-* Installation Changes in Emacs 28.1
-
-** Emacs now optionally supports native compilation of Lisp files.
-To enable this, configure Emacs with the '--with-native-compilation' option.
-This requires the libgccjit library to be installed and functional,
-and also requires GCC and Binutils to be available when Lisp code is
-natively compiled. See the Info node "(elisp) Native Compilation" for
-more details.
-
-If you build Emacs with native compilation, but without zlib, be sure
-to configure with the '--without-compress-install' option, so that the
-installed *.el files are not compressed; otherwise, you will not be
-able to use JIT native compilation of the installed *.el files.
-
-** The Cairo graphics library is now used by default if present.
-'--with-cairo' is now the default, if the appropriate development files
-are found by 'configure'. Note that building with Cairo means using
-Pango instead of libXFT for font support. Since Pango 1.44 has
-removed support for bitmapped fonts, this may require you to adjust
-your font settings.
-
-Note also that 'FontBackend' settings in ".Xdefaults" or
-".Xresources", or 'font-backend' frame parameter settings in your init
-files, may need to be adjusted, as 'xft' is no longer a valid backend
-when using Cairo. Use 'ftcrhb' if your Emacs was built with HarfBuzz
-text shaping support, and 'ftcr' otherwise. You can determine this by
-checking 'system-configuration-features'. The 'ftcr' backend will
-still be available when HarfBuzz is supported, but will not be used by
-default. We strongly recommend building with HarBuzz support. 'x' is
-still a valid backend.
-
----
-** 'configure' now warns about building with libXft support.
-libXft is unmaintained, and causes a number of problems with modern
-fonts including but not limited to crashes; support for it may be
-removed in a future version of Emacs. Please consider using
-Cairo + HarfBuzz instead.
-
----
-** 'configure' now warns about not using HarfBuzz if using Cairo.
-We want to encourage people to use the most modern font features
-available, and this is the Cairo graphics library + HarfBuzz for font
-shaping, so 'configure' now recommends that combination.
-
----
-** Building without double buffering support.
-'configure --with-xdbe=no' can now be used to disable double buffering
-at build time.
-
----
-** Support for building with Motif has been removed.
-
----
-** The configure option '--without-makeinfo' has been removed.
-This was only ever relevant when building from a repository checkout.
-This now requires makeinfo, which is part of the texinfo package.
-
----
-** Support for building with '-fcheck-pointer-bounds' has been removed.
-GCC has withdrawn the '-fcheck-pointer-bounds' option and support for
-its implementation has been removed from the Linux kernel.
-
----
-** The ftx font backend driver has been removed.
-It was declared obsolete in Emacs 27.1.
-
----
-** Emacs no longer supports old OpenBSD systems.
-OpenBSD 5.3 and older releases are no longer supported, as they lack
-proper pty support that Emacs needs.
-
-
-* Startup Changes in Emacs 28.1
-
----
-** In GTK builds, Emacs now supports startup notification.
-This means that Emacs won't steal keyboard focus upon startup
-(when started via the Desktop) if the user is typing into another
-application.
-
----
-** Errors in 'kill-emacs-hook' no longer prevent Emacs from shutting down.
-If a function in that hook signals an error in an interactive Emacs,
-the user will be prompted on whether to continue. If the user doesn't
-answer within five seconds, Emacs will continue shutting down anyway.
-
-** Emacs now supports loading a Secure Computing filter.
-This is supported only on capable GNU/Linux systems. To activate,
-invoke Emacs with the '--seccomp=FILE' command-line option. FILE must
-name a binary file containing an array of 'struct sock_filter'
-structures. Emacs will then install that list of Secure Computing
-filters into its own process early during the startup process. You
-can use this functionality to put an Emacs process in a sandbox to
-avoid security issues when executing untrusted code. See the manual
-page for 'seccomp' system call, for details about Secure Computing
-filters.
-
-** Emacs can support 24-bit color TTY without terminfo database.
-If your text-mode terminal supports 24-bit true color, but your system
-lacks the terminfo database, you can instruct Emacs to support 24-bit
-true color by setting 'COLORTERM=truecolor' in the environment. This is
-useful on systems such as FreeBSD which ships only with "etc/termcap".
-
----
-** File names given on the command line are now be pushed onto history.
-The file names will be pushed onto 'file-name-history', like the names
-of files visited via 'C-x C-f' and other commands.
-
-
-* Changes in Emacs 28.1
-
----
-** Emacs now supports Unicode Standard version 14.0.
-
-+++
-** New character script 'emoji' has been created.
-Various blocks of codepoints have been split out of the 'symbol'
-script into their own 'emoji' script to allow easier specification of
-their treatment. Which codepoints are treated as emoji is derived
-from the Unicode specifications. Also, Emacs will now use "Noto Color
-Emoji" by default for that script. Use:
-
-(set-fontset-font t 'emoji
- '("My New Emoji Font" . "iso10646-1") nil 'prepend)
-
-to change the font used.
-
-+++
-** Zero Width Joiner (ZWJ) and emoji sequences are now composed.
-Emacs can now compose (almost) all the Unicode-14 ZWJ and emoji
-sequences (if a suitable font is installed) so that they are displayed
-as single glyphs instead of multiple ones. 'Noto Color Emoji' is one
-such suitable font.
-
-+++
-** Composition of emoji has been improved.
-If autocomposition is triggered by an emoji character, then the emoji
-font is now used to check if composition can be performed, rather than
-the font of the first character of the string being composed. This
-allows e.g.
-
-'Emoji codepoint' + VS-16
-
-to be displayed using the emoji font even if 'Emoji codepoint' does
-not have emoji presentation by default.
-
-+++
-** 'glyphless-char-display-control' now applies to Variation Selectors.
-VS-1 through VS-16 are now displayed as 'thin-space' by default when
-not composed.
-
-+++
-** New command 'execute-extended-command-for-buffer'.
-This new command, bound to 'M-S-x', works like
-'execute-extended-command', but limits the set of commands to the
-commands that have been determined to be particularly useful with the
-current mode.
-
-+++
-** New user option 'read-extended-command-predicate'.
-This user option controls how 'M-x' performs completion of commands when
-you type 'TAB'. By default, any command that matches what you have
-typed is considered a completion candidate, but you can customize this
-option to exclude commands that are not applicable to the current
-buffer's major and minor modes, and respect the command's completion
-predicate (if any).
-
-+++
-** Completion on 'M-x' shows key bindings for commands.
-When 'suggest-key-bindings' is non-nil (as it is by default), the
-completion list popped up by 'M-x' shows the key bindings for all the
-commands shown in the list of candidate completions that have a key
-binding.
-
-+++
-** New user option 'completions-detailed'.
-When non-nil, some commands like 'describe-symbol' show more detailed
-completions with more information in completion prefix and suffix.
-The default is nil.
-
----
-** 'C-s' in 'M-x' now once again searches over completions.
-In Emacs 23, typing 'M-x' ('read-extended-command') and then 'C-s' (to
-do an interactive search) would search over possible completions.
-This was lost in Emacs 24, but is now back again.
-
----
-** User option 'completions-format' supports a new value 'one-column'.
-
-+++
-** New system for displaying documentation for groups of functions.
-This can either be used by saying 'M-x shortdoc-display-group' and
-choosing a group, or clicking a button in the "*Help*" buffers when
-looking at the doc string of a function that belongs to one of these
-groups.
-
-+++
-** New minor mode 'context-menu-mode' for context menus popped by 'mouse-3'.
-When this mode is enabled, clicking 'down-mouse-3' anywhere in the buffer
-pops up a menu whose contents depends on surrounding context near the
-mouse click. You can change the order of the default sub-menus in the
-context menu by customizing the user option 'context-menu-functions'.
-You can also invoke the context menu by pressing 'S-<F10>' or,
-on macOS, by clicking 'C-down-mouse-1'.
-
-+++
-** A new keymap for buffer actions has been added.
-The 'C-x x' keymap now holds keystrokes for various buffer-oriented
-commands. The new keystrokes are 'C-x x g' ('revert-buffer-quick'),
-'C-x x r' ('rename-buffer'), 'C-x x u' ('rename-uniquely'), 'C-x x n'
-('clone-buffer'), 'C-x x i' ('insert-buffer'), 'C-x x t'
-('toggle-truncate-lines') and 'C-x x f' ('font-lock-update').
-
-+++
-** Modifiers now go outside angle brackets in pretty-printed key bindings.
-For example, 'RET' with Control and Meta modifiers is now shown as
-'C-M-<return>' instead of '<C-M-return>'. Either variant can be used
-as input; functions such as 'kbd' and 'read-kbd-macro' accept both
-styles as equivalent (they have done so for a long time).
-
----
-** 'eval-expression' no longer signals an error on incomplete expressions.
-Previously, typing 'M-: ( RET' would result in Emacs saying "End of
-file during parsing" and dropping out of the minibuffer. The user
-would have to type 'M-: M-p' to edit and redo the expression. Now
-Emacs will echo the message and allow the user to continue editing.
-
-+++
-** 'eval-last-sexp' now handles 'defvar'/'defcustom'/'defface' specially.
-This command would previously not redefine values defined by these
-forms, but this command has now been changed to work more like
-'eval-defun', and reset the values as specified.
-
----
-** New user option 'use-short-answers'.
-When non-nil, the function 'y-or-n-p' is used instead of
-'yes-or-no-p'. This eliminates the need to define an alias that maps
-one to another in the init file. The same user option also controls
-whether the function 'read-answer' accepts short answers.
-
-+++
-** New user option 'kill-buffer-delete-auto-save-files'.
-If non-nil, killing a buffer that has an auto-save file will prompt
-the user for whether that file should be deleted. (Note that
-'delete-auto-save-files', if non-nil, was previously documented to
-result in deletion of auto-save files when killing a buffer without
-unsaved changes, but this has apparently not worked for several
-decades, so the documented semantics of this variable has been changed
-to match the behavior.)
-
-+++
-** New user option 'next-error-message-highlight'.
-In addition to a fringe arrow, 'next-error' error may now optionally
-highlight the current error message in the 'next-error' buffer.
-This user option can be also customized to keep highlighting on all
-visited errors, so you can have an overview what errors were already visited.
-
----
-** New choice 'next-error-quit-window' for 'next-error-found-function'.
-When 'next-error-found-function' is customized to 'next-error-quit-window',
-then typing the numeric prefix argument 0 before the command 'next-error'
-will quit the source window after visiting the next occurrence.
-
-+++
-** New user option 'file-preserve-symlinks-on-save'.
-This controls what Emacs does when saving buffers that visit files via
-symbolic links, and 'file-precious-flag' is non-nil.
-
-+++
-** New user option 'copy-directory-create-symlink'.
-If non-nil, will make 'copy-directory' (when used on a symbolic
-link) copy the link instead of following the link. The default is
-nil, so the default behavior is unchanged.
-
-+++
-** New user option 'ignored-local-variable-values'.
-This is the opposite of 'safe-local-variable-values' -- it's an alist
-of variable-value pairs that are to be ignored when reading a
-local-variables section of a file.
-
----
-** Specific warnings can now be disabled from the warning buffer.
-When a warning is displayed to the user, the resulting buffer now has
-buttons which allow making permanent changes to the treatment of that
-warning. Automatic showing of the warning can be disabled (although
-it is still logged to the "*Messages*" buffer), or the warning can be
-disabled entirely.
-
-+++
-** ".dir-locals.el" now supports setting 'auto-mode-alist'.
-The new 'auto-mode-alist' specification in ".dir-locals.el" files can
-now be used to override the global 'auto-mode-alist' in the current
-directory tree.
-
----
-** User option 'uniquify-buffer-name-style' can now be a function.
-This user option can be one of the predefined styles or a function to
-personalize the uniquified buffer name.
-
----
-** 'remove-hook' is now an interactive command.
-
----
-** 'expand-file-name' now checks for null bytes in filenames.
-The function will now check for null bytes in both NAME and
-DEFAULT-DIRECTORY arguments, as well as in the 'default-directory'
-buffer-local variable, when its value is used. If null bytes are
-found, 'expand-file-name' will signal an error.
-This means that practically all file-related operations will now check
-file names for null bytes, thus avoiding subtle bugs with silently
-using only the part of file name up to the first null byte.
-
----
-** Frames
-
-+++
-*** The key prefix 'C-x 5 5' displays next command buffer in a new frame.
-It's bound to the command 'other-frame-prefix' that requests the buffer
-of the next command to be displayed in a new frame.
-
-+++
-*** New command 'clone-frame' (bound to 'C-x 5 c').
-This is like 'C-x 5 2', but uses the frame parameters of the current
-frame instead of 'default-frame-alist'.
-
----
-*** Default values of 'frame-title-format' and 'icon-title-format' have
changed.
-These variables are used to display the title bar of visible frames
-and the title bar of an iconified frame. They now show the name of
-the current buffer and the text "GNU Emacs" instead of the value of
-'invocation-name'. To get the old behavior back, add the following to
-your init file:
-
- (setq frame-title-format '(multiple-frames "%b"
- ("" invocation-name "@" system-name)))
-
-+++
-*** New frame parameter 'drag-with-tab-line'.
-This parameter, similar to 'drag-with-header-line', allows moving frames
-by dragging the tab lines of their topmost windows with the mouse.
-
-+++
-*** New optional behavior of 'delete-other-frames'.
-When invoked with a prefix argument, 'delete-other-frames' now
-iconifies frames, rather than deleting them.
-
----
-*** Commands 'set-frame-width' and 'set-frame-height' now prompt for values.
-These commands now prompt for the value via the minibuffer, instead of
-requiring the user to specify the value via the prefix argument.
-
-** Windows
-
-*** The key prefix 'C-x 4 1' displays next command buffer in the same window.
-It's bound to the command 'same-window-prefix' that requests the buffer
-of the next command to be displayed in the same window.
-
-*** The key prefix 'C-x 4 4' displays next command buffer in a new window.
-It's bound to the command 'other-window-prefix' that requests the buffer
-of the next command to be displayed in a new window.
-
-+++
-*** New command 'recenter-other-window', bound to 'S-M-C-l'.
-Like 'recenter-top-bottom' acting on the other window.
-
-+++
-*** New user option 'delete-window-choose-selected'.
-This allows to choose a window that will be the frame's selected
-window after deleting the currently selected one.
-
-+++
-*** New argument NO-OTHER for some window functions.
-'get-lru-window', 'get-mru-window' and 'get-largest-window' now accept a
-new optional argument NO-OTHER which, if non-nil, avoids returning a
-window whose 'no-other-window' parameter is non-nil.
-
-+++
-*** New 'display-buffer' function 'display-buffer-use-least-recent-window'.
-This is like 'display-buffer-use-some-window', but won't reuse the
-current window, and when called repeatedly will try not to reuse a
-previously selected window.
-
-+++
-*** New function 'window-bump-use-time'.
-This updates the use time of a window.
-
-** Minibuffer
-
-+++
-*** Minibuffer scrolling is now conservative by default.
-This is controlled by the new variable 'scroll-minibuffer-conservatively'.
-It is t by default; setting it to nil will cause scrolling in the
-minibuffer obey the value of 'scroll-conservatively'.
-
-+++
-*** Improved handling of minibuffers on switching frames.
-By default, when you switch to another frame, an active minibuffer now
-moves to the newly selected frame. Nevertheless, the effect of what
-you type in the minibuffer happens in the frame where the minibuffer
-was first activated. An alternative behavior is available by
-customizing 'minibuffer-follows-selected-frame' to nil. Here, the
-minibuffer stays in the frame where you first opened it, and you must
-switch back to this frame to continue or abort its command. The old
-behavior, which mixed these two, can be approximated by customizing
-'minibuffer-follows-selected-frame' to a value which is neither nil
-nor t.
-
-+++
-*** New user option 'read-minibuffer-restore-windows'.
-When customized to nil, it uses 'minibuffer-restore-windows' in
-'minibuffer-exit-hook' to remove only the window showing the
-"*Completions*" buffer.
-
----
-*** New variable 'redisplay-adhoc-scroll-in-resize-mini-windows'.
-Customizing it to nil will disable the ad-hoc auto-scrolling of
-minibuffer text shown in mini-windows when resizing those windows.
-The default heuristics of that scrolling can be counter productive in
-some corner cases, though the cure might be worse than the disease.
-This said, the effect should be negligible in the vast majority of
-cases anyway.
-
-** Mode Line
-
-+++
-*** New user option 'mode-line-compact'.
-If non-nil, repeating spaces are compressed into a single space. If
-'long', this is only done when the mode line is longer than the
-current window width (in columns).
-
-+++
-*** New user options to control format of line/column numbers in the mode line.
-'mode-line-position-line-format' is the line number format (when
-'line-number-mode' is on), 'mode-line-position-column-format' is
-the column number format (when 'column-number-mode' is on), and
-'mode-line-position-column-line-format' is the combined format (when
-both modes are on).
-
-** Tab Bars and Tab Lines
-
-+++
-*** The prefix key 'C-x t t' can be used to display a buffer in a new tab.
-Typing 'C-x t t' before a command will cause the buffer shown by that
-command to be displayed in a new tab. 'C-x t t" is bound to the
-command 'other-tab-prefix'.
-
-+++
-*** New command 'C-x t C-r' to open file read-only in the other tab.
-
-*** The tab bar now supports more mouse commands.
-Clicking 'mouse-2' closes the tab, 'mouse-3' displays the context menu
-with items that operate on the clicked tab. Dragging the tab with
-'mouse-1' moves it to another position on the tab bar. Mouse wheel
-scrolling switches to the previous/next tab, and holding the Shift key
-during scrolling moves the tab to the left/right.
-
----
-*** Frame-specific appearance of the tab bar when 'tab-bar-show' is a number.
-When 'tab-bar-show' is a number, the tab bar on different frames can
-be shown or hidden independently, as determined by the number of tabs
-on each frame compared to the numerical value of 'tab-bar-show'.
-
----
-*** New command 'toggle-frame-tab-bar'.
-It can be used to enable/disable the tab bar on the currently selected
-frame regardless of the values of 'tab-bar-mode' and 'tab-bar-show'.
-This allows to enable/disable the tab bar independently on different
-frames.
-
----
-*** New user option 'tab-bar-format' defines a list of tab bar items.
-When it contains 'tab-bar-format-global' (possibly appended after
-'tab-bar-format-align-right'), then after enabling 'display-time-mode'
-(or any other mode that uses 'global-mode-string') it displays time
-aligned to the right on the tab bar instead of on the mode line.
-When 'tab-bar-format-tabs' is replaced with 'tab-bar-format-tabs-groups',
-the tab bar displays tab groups.
-
----
-*** New optional key binding for 'tab-last'.
-If you customize the user option 'tab-bar-select-tab-modifiers' for
-selecting tabs using its index numbers, the '<MODIFIER>-9' key is
-bound to 'tab-last', and switches to the last tab. Here <MODIFIER> is
-any of the modifiers in the list that is the value of
-'tab-bar-select-tab-modifiers'. You can also use negative indices,
-which count from the last tab: -1 is the last tab, -2 the one before
-that, etc.
-
----
-*** New command 'tab-duplicate' bound to 'C-x t n'.
-
----
-*** 'C-x t N' creates a new tab at the specified absolute position.
-The position is provided as prefix arg, and specifies an index that
-starts at 1. Negative values count from the end of the tab bar.
-
----
-*** 'C-x t M' moves the current tab to the specified absolute position.
-The position is provided as prefix arg, whose interpretation is as in
-'C-x t N'.
-
----
-*** 'C-x t G' assigns a tab to a named group of tabs.
-'tab-close-group' closes all tabs that belong to the selected group.
-The user option 'tab-bar-new-tab-group' defines the default group of
-new tabs. After customizing 'tab-bar-tab-post-change-group-functions'
-to 'tab-bar-move-tab-to-group', changing the group of a tab will also
-move it closer to other tabs in the same group.
-
----
-*** New user option 'tab-bar-tab-name-format-function'.
-
----
-*** New user option 'tab-line-tab-name-format-function'.
-
----
-*** The tabs in the tab line can now be scrolled using horizontal scroll.
-If your mouse or trackpad supports it, you can now scroll tabs when
-the mouse pointer is in the tab line by scrolling left or right.
-
----
-*** New tab-line faces and options.
-The face 'tab-line-tab-special' is used for tabs whose buffers are
-special, i.e. buffers that don't visit a file. The face
-'tab-line-tab-modified' is used to display modified, file-backed
-buffers. The face 'tab-line-tab-inactive-alternate' is used to
-display inactive tabs with an alternating background color, making
-them easier to distinguish, especially if the face 'tab-line-tab' is
-configured to not display with a box; this alternate face is only
-applied when the option 'tab-line-tab-face-functions' is so
-configured. That option may also be used to customize tab-line faces
-in other ways.
-
-** Mouse wheel
-
----
-*** Mouse wheel scrolling now defaults to one line at a time.
-
----
-*** Mouse wheel scrolling now works on more parts of frame's display.
-When using 'mwheel-mode', the mouse wheel will now scroll also when
-the mouse cursor is on the scroll bars, fringes, margins, header line,
-and mode line. ('mwheel-mode' is enabled by default on most graphical
-displays.)
-
-+++
-*** Mouse wheel scrolling with Shift modifier now scrolls horizontally.
-This works in text buffers and over images. Typing a numeric prefix arg
-(e.g. 'M-5') before starting horizontal scrolling changes its step value.
-The value is saved in the user option 'mouse-wheel-scroll-amount-horizontal'.
-
-** Customize
-
----
-*** Customize buffers can now be reverted with 'C-x x g'.
-
----
-*** Most customize commands now hide obsolete user options.
-Obsolete user options are no longer shown in the listings produced by
-the commands 'customize', 'customize-group', 'customize-apropos' and
-'customize-changed'.
-
-To customize obsolete user options, use 'customize-option' or
-'customize-saved'.
-
----
-*** New SVG icons for checkboxes and arrows.
-They will be used automatically instead of the old icons. If Emacs is
-built without SVG support, the old icons will be used instead.
-
-** Help
-
----
-*** The order things are displayed in the *Help* buffer has been changed.
-The indented "administrative" block (containing the "probably
-introduced" and "other relevant functions" (and similar things) has
-been moved to after the doc string.
-
-+++
-*** New command 'describe-command' shows help for a command.
-This can be used instead of 'describe-function' for interactive
-commands and is globally bound to 'C-h x'.
-
-+++
-*** New command 'describe-keymap' describes keybindings in a keymap.
-
----
-*** New command 'apropos-function'.
-This works like 'C-u M-x apropos-command' but is more discoverable.
-
----
-*** New keybinding 'C-h R' prompts for an Info manual and displays it.
-
----
-*** Keybindings in 'help-mode' use the new 'help-key-binding' face.
-This face is added by 'substitute-command-keys' to any "\[command]"
-substitution. The return value of that function should consequently
-be assumed to be a propertized string.
-
-Note that the new face will also be used in tooltips. When using the
-GTK toolkit, this is only true if 'x-gtk-use-system-tooltips' is t.
-
-+++
-*** New user option 'help-enable-symbol-autoload'.
-If non-nil, displaying help for an autoloaded function whose
-'autoload' form provides no documentation string will try to load the
-file it's from. This will give more extensive help for such
-functions.
-
----
-*** The 'help-for-help' ('C-h C-h') screen has been redesigned.
-
-+++
-*** New convenience commands with short keys in the Help buffer.
-New command 'help-view-source' ('s') will view the source file (if
-any) of the current help topic. New command 'help-goto-info' ('i')
-will look up the current symbol (if any) in Info. New command
-'help-customize' ('c') will customize the user option or the face
-(if any) whose doc string is being shown in the Help buffer.
-
----
-*** New user option 'describe-bindings-outline'.
-It enables outlines in the output buffer of 'describe-bindings' that
-can provide a better overview in a long list of available bindings.
-
-+++
-*** New command 'lossage-size'.
-It allows users to change the maximum number of keystrokes and
-commands recorded for the purpose of 'view-lossage'.
-
-+++
-*** New commands to describe buttons and widgets.
-'widget-describe' (on a widget) will pop up a help buffer and give a
-description of the properties. Likewise 'button-describe' does the
-same for a button.
-
----
-*** Improved "find definition" feature of "*Help*" buffers.
-Now clicking on the link to find the definition of functions generated
-by 'cl-defstruct', or variables generated by 'define-derived-mode',
-for example, will go to the exact place where they are defined.
-
----
-*** New commands 'apropos-next-symbol' and 'apropos-previous-symbol'.
-These new navigation commands are bound to 'n' and 'p' in
-'apropos-mode'.
-
----
-*** The command 'view-lossage' can now be invoked from the menu bar.
-The menu bar "Help" menu now has a "Show Recent Inputs" item under the
-"Describe" sub-menu.
-
----
-*** Closing the "*Help*" buffer from the toolbar now buries the buffer.
-In previous Emacs versions, the "*Help*" buffer was killed instead when
-clicking the "X" icon in the tool bar.
-
----
-*** 'g' ('revert-buffer') in 'help-mode' no longer requires confirmation.
-
-** File Locks
-
-+++
-*** New user option 'lock-file-name-transforms'.
-This option allows controlling where lock files are written. It uses
-the same syntax as 'auto-save-file-name-transforms'.
-
-+++
-*** New user option 'remote-file-name-inhibit-locks'.
-When non-nil, this option suppresses lock files for remote files.
-
-+++
-*** New minor mode 'lock-file-mode'.
-This command, called interactively, toggles the local value of
-'create-lockfiles' in the current buffer.
-
-** Emacs Server
-
-+++
-*** New user option 'server-client-instructions'.
-When emacsclient connects, Emacs will (by default) output a message
-about how to exit the client frame. If 'server-client-instructions'
-is set to nil, this message is inhibited.
-
-+++
-*** New command 'server-edit-abort'.
-This command (not bound to any key by default) can be used to abort
-an edit instead of marking it as "Done" (which the 'C-x #' command
-does). The 'emacsclient' program exits with an abnormal status as
-result of this command.
-
-+++
-*** New desktop integration for connecting to the server.
-If your operating system’s desktop environment is
-freedesktop.org-compatible (which is true of most GNU/Linux and other
-recent Unix-like desktops), you may use the new "Emacs (Client)"
-desktop menu entry to open files in an existing Emacs instance rather
-than starting a new one. The daemon starts if it is not already
-running.
-
-** Miscellaneous
-
-+++
-*** New command 'font-lock-update', bound to 'C-x x f'.
-This command updates the syntax highlighting in this buffer.
-
-+++
-*** New command 'memory-report'.
-This command opens a new buffer called "*Memory Report*" and gives a
-summary of where Emacs is using memory currently.
-
-+++
-*** New command 'submit-emacs-patch'.
-This works like 'report-emacs-bug', but is more geared towards sending
-patches to the Emacs issue tracker.
-
----
-*** New face 'apropos-button'.
-Applies to buttons that indicate a face.
-
-+++
-*** New face 'font-lock-doc-markup-face'.
-Intended for documentation mark-up syntax and tags inside text that
-uses 'font-lock-doc-face', with which it should harmonize. It would
-typically be used in structured documentation comments in program
-source code by language-specific modes, for mark-up conventions like
-Haddock, Javadoc or Doxygen. By default this face inherits from
-'font-lock-constant-face'.
-
-+++
-*** New face 'flat-button'.
-This is a plain 2D button, but uses the background color instead of
-the foreground color.
-
----
-*** New face 'shortdoc-heading'.
-Applies to headings of shortdoc sections.
-
----
-*** New face 'separator-line'.
-This is used by 'make-separator-line' (see below).
-
-+++
-*** 'redisplay-skip-fontification-on-input' helps Emacs keep up with fast
input.
-This is another attempt to solve the problem of handling high key repeat rate
-and other "slow scrolling" situations. It is hoped it behaves better
-than 'fast-but-imprecise-scrolling' and 'jit-lock-defer-time'.
-It is not enabled by default.
-
----
-*** Obsolete aliases are no longer hidden from command completion.
-Completion of command names now considers obsolete aliases as
-candidates, if they were marked obsolete in the current major version
-of Emacs. Invoking a command via an obsolete alias now mentions the
-obsolescence fact and shows the new name of the command.
-
-+++
-*** Support for '(box . SIZE)' 'cursor-type'.
-By default, 'box' cursor always has a filled box shape. But if you
-specify 'cursor-type' to be '(box . SIZE)', the cursor becomes a hollow
-box if the point is on an image larger than SIZE pixels in any
-dimension.
-
-+++
-*** The user can now customize how "default" values are prompted for.
-The new utility function 'format-prompt' has been added which uses the
-new 'minibuffer-default-prompt-format' user option to format "default"
-prompts. This means that prompts that look like "Enter a number
-(default 10)" can be customized to look like, for instance, "Enter a
-number [10]", or not have the default displayed at all, like "Enter a
-number". (This only affects callers that were altered to use
-'format-prompt'.)
-
----
-*** New help window when Emacs prompts before opening a large file.
-Commands like 'find-file' or 'visit-tags-table' ask to visit a file
-normally or literally when the file is larger than a certain size (by
-default, 9.5 MiB). Press '?' or 'C-h' in that prompt to read more
-about the different options to visit a file, how you can disable the
-prompt, and how you can tweak the file size threshold.
-
-+++
-*** Emacs now defaults to UTF-8 instead of ISO-8859-1.
-This is only for the default, where the user has set no 'LANG' (or
-similar) variable or environment. This change should lead to no
-user-visible changes for normal usage.
-
----
-*** 'global-display-fill-column-indicator-mode' skips some buffers.
-By default, turning on 'global-display-fill-column-indicator-mode'
-doesn't turn on 'display-fill-column-indicator-mode' in special-mode
-buffers. This can be controlled by customizing the user option
-'global-display-fill-column-indicator-modes'.
-
-+++
-*** 'nobreak-char-display' now also affects all non-ASCII space characters.
-Previously, this was limited only to 'NO-BREAK SPACE' and hyphen
-characters. Now it also covers the rest of the non-ASCII Unicode
-space characters.
-
-+++
-*** Improved support for terminal emulators that encode the Meta flag.
-Some terminal emulators set the 8th bit of Meta characters, and then
-encode the resulting character code as if it were non-ASCII character
-above codepoint 127. Previously, the only way of using these in Emacs
-was to set up the terminal emulator to use the 'ESC' characters to send
-Meta characters to Emacs, e.g., send "ESC x" when the user types
-'M-x'. You can now avoid the need for this setup of such terminal
-emulators by using the new input-meta-mode with the special value
-'encoded' with these terminal emulators.
-
----
-*** 'auto-composition-mode' can now be selectively disabled on some TTYs.
-Some text-mode terminals produce display glitches trying to compose
-characters. The 'auto-composition-mode' can now have a string value
-that names a terminal type; if the value returned by the 'tty-type'
-function compares equal with that string, automatic composition will
-be disabled in windows shown on that terminal. The Linux terminal
-sets this up by default.
-
----
-*** Support for the 'strike-through' face attribute on TTY frames.
-If your terminal's termcap or terminfo database entry has the 'smxx'
-capability defined, Emacs will now emit the prescribed escape
-sequences necessary to render faces with the 'strike-through'
-attribute on TTY frames.
-
----
-*** TTY menu navigation is now supported in 'xterm-mouse-mode'.
-TTY menus support mouse navigation and selection when 'xterm-mouse-mode'
-is active. When run on a terminal, clicking on the menu bar with the
-mouse now pops up a TTY menu by default instead of running the command
-'tmm-menubar'. To restore the old behavior, set the user option
-'tty-menu-open-use-tmm' to non-nil.
-
----
-*** 'M-x report-emacs-bug' will no longer include "Recent messages" section.
-These were taken from the "*Messages*" buffer, and may inadvertently
-leak information from the reporting user.
-
----
-*** 'C-u M-x dig' will now prompt for a query type to use.
-
----
-*** Rudimentary support for the 'st' terminal emulator.
-Emacs now supports 256 color display on the 'st' terminal emulator.
-
-+++
-*** Update IRC-related references to point to Libera.Chat.
-The Free Software Foundation and the GNU Project have moved their
-official IRC channels from the Freenode network to Libera.Chat. For the
-original announcement and the follow-up update, including more details,
-see:
-
-https://lists.gnu.org/archive/html/info-gnu/2021-06/msg00005.html
-https://lists.gnu.org/archive/html/info-gnu/2021-06/msg00007.html
-
-Given the relocation of GNU and FSF's official IRC channels, as well
-as #emacs and various other Emacs-themed channels (see the link below)
-to Libera.Chat, IRC-related references in the Emacs repository have
-now been updated to point to Libera.Chat.

-
-* Editing Changes in Emacs 28.1
-
-** Input methods
-
-+++
-*** Emacs now supports "transient" input methods.
-A transient input method is enabled for inserting a single character,
-and is then automatically disabled. 'C-x \' temporarily enables the
-selected transient input method. Use 'C-u C-x \' to select a
-transient input method (which can be different from the input method
-enabled by 'C-\'). For example, 'C-u C-x \ compose RET' selects the
-'compose' input method; then typing 'C-x \ 1 2' will insert the
-character '½', and disable the 'compose' input method afterwards.
-You can use 'C-x \' in incremental search to insert a single character
-to the search string.
-
----
-*** New input method 'compose' based on X Multi_key sequences.
-
----
-*** New input method 'iso-transl' with the same keys as 'C-x 8'.
-After selecting it as a transient input method with 'C-u C-x \
-iso-transl RET', it supports the same key sequences as 'C-x 8',
-so e.g. like 'C-x 8 [' inserts a left single quotation mark,
-'C-x \ [' does the same.
-
----
-*** New user option 'read-char-by-name-sort'.
-It defines the sorting order of characters for completion of 'C-x 8 RET TAB'
-and can be customized to sort them by codepoints instead of character names.
-Additionally, you can group characters by Unicode blocks after customizing
-'completions-group' and 'completions-group-sort'.
-
----
-*** Improved language transliteration in Malayalam input methods.
-Added a new Mozhi scheme. The inapplicable ITRANS scheme is now
-deprecated. Errors in the Inscript method were corrected.
-
----
-*** New input method 'cham'.
-There's also a Cham greeting in "etc/HELLO".
-
----
-*** New input methods for Lakota language orthographies.
-Two orthographies are represented here, the Suggested Lakota
-Orthography and what is known as the White Hat Orthography. Input
-methods 'lakota-slo-prefix', 'lakota-slo-postfix', and
-'lakota-white-hat-postfix' have been added. There is also a Lakota
-greeting in "etc/HELLO".
-
-+++
-** Standalone 'M-y' allows interactive selection from previous kills.
-'M-y' can now be typed after a command that is not a yank command.
-When invoked like that, it prompts in the minibuffer for one of the
-previous kills, offering completion and minibuffer-history navigation
-through previous kills recorded in the kill ring. A similar feature
-in Isearch can be invoked if you bind 'C-s M-y' to the command
-'isearch-yank-pop'. When the user option 'yank-from-kill-ring-rotate'
-is nil the kill ring is not rotated after 'yank-from-kill-ring'.
-
-+++
-** New user option 'word-wrap-by-category'.
-When word-wrap is enabled, and this option is non-nil, that allows
-Emacs to break lines after more characters than just whitespace
-characters. In particular, this significantly improves word-wrapping
-for CJK text mixed with Latin text.
-
-+++
-** New command 'undo-redo'.
-It undoes previous undo commands, but doesn't record itself as an
-undoable command. It is bound to 'C-?' and 'C-M-_', the first binding
-works well in graphical mode, and the second one is easy to hit on tty.
-
-For full conventional undo/redo behavior, you can also customize the
-user option 'undo-no-redo' to t.
-
-+++
-** New commands 'copy-matching-lines' and 'kill-matching-lines'.
-These commands are similar to the command 'flush-lines',
-but add the matching lines to the kill ring as a single string,
-including the newlines that separate the lines.
-
-+++
-** New user option 'kill-transform-function'.
-This can be used to transform (and suppress) strings from entering the
-kill ring.
-
-+++
-** 'save-interprogram-paste-before-kill' can now be a number.
-In that case, it's interpreted as a limit on the size of the clipboard
-data that will be saved to the 'kill-ring' prior to killing text: if
-the size of the clipboard data is greater than or equal to the limit,
-it will not be saved.
-
-+++
-** New user option 'tab-first-completion'.
-If 'tab-always-indent' is 'complete', this new user option can be used to
-further tweak whether to complete or indent.
-
----
-** 'indent-tabs-mode' is now a global minor mode instead of just a variable.
-
----
-** New choice 'permanent' for 'shift-select-mode'.
-When the mark was activated by shifted motion keys, non-shifted motion
-keys don't deactivate the mark after customizing 'shift-select-mode'
-to 'permanent'.
-
-+++
-** The "Edit => Clear" menu item now obeys a rectangular region.
-
-+++
-** New command 'revert-buffer-with-fine-grain'.
-Revert a buffer trying to be as non-destructive as possible,
-preserving markers, properties and overlays. The new variable
-'revert-buffer-with-fine-grain-max-seconds' specifies the maximum
-number of seconds that 'revert-buffer-with-fine-grain' should spend
-trying to be non-destructive, with a default value of 2 seconds.
-
-+++
-** New command 'revert-buffer-quick'.
-This is bound to 'C-x x g' and is like 'revert-buffer', but prompts
-less.
-
-+++
-** New user option 'revert-buffer-quick-short-answers'.
-This controls how the new 'revert-buffer-quick' ('C-x x g') command
-prompts.
-
-+++
-** New user option 'query-about-changed-file'.
-If non-nil (the default), Emacs prompts as before when re-visiting a
-file that has changed externally after it was visited the first time.
-If nil, Emacs does not prompt, but instead shows the buffer with its
-contents before the change, and provides instructions how to revert
-the buffer.
-
----
-** New value 'save-some-buffers-root' of 'save-some-buffers-default-predicate'.
-When using this predicate, only buffers under the current project root
-will be considered when saving buffers with 'save-some-buffers'.
-
----
-** New user option 'save-place-abbreviate-file-names'.
-This can simplify sharing the 'save-place-file' file across
-different hosts.
-
----
-** New user options 'copy-region-blink-delay' and 'delete-pair-blink-delay'.
-'copy-region-blink-delay' specifies a delay to indicate the region
-copied by 'kill-ring-save'. 'delete-pair-blink-delay' specifies
-a delay to show the paired character to delete.
-
----
-** 'zap-up-to-char' now uses 'read-char-from-minibuffer'.
-This allows navigating through the history of characters that have
-been input. This is mostly useful for characters that have complex
-input methods where inputting the character again may involve many
-keystrokes.
-
-+++
-** Input history for 'goto-line' can now be made local to every buffer.
-In any event, line numbers used with 'goto-line' are kept in their own
-history list. This should help make faster the process of finding
-line numbers that were previously jumped to. By default, all buffers
-share a single history list. To make every buffer have its own
-history list, customize the user option 'goto-line-history-local'.
-
-+++
-** New command 'goto-line-relative' for use in a narrowed buffer.
-It moves point to the line relative to the accessible portion of the
-narrowed buffer. 'M-g M-g' in Info is rebound to this command.
-When 'widen-automatically' is non-nil, 'goto-line' widens the narrowed
-buffer to be able to move point to the inaccessible portion.
-'goto-line-relative' is bound to 'C-x n g'.
-
-+++
-** 'got-char' prompts for the character position.
-When called interactively, 'goto-char' now offers the position at
-point as the default.
-
-** Autosaving via 'auto-save-visited-mode' can now be inhibited.
-Set the variable 'auto-save-visited-mode' buffer-locally to nil to
-achieve that.
-
-+++
-** New command 'kdb-macro-redisplay' to force redisplay in keyboard macros.
-This command is bound to 'C-x C-k d'.
-
----
-** 'blink-cursor-mode' is now enabled by default regardless of the UI.
-It used to be enabled when Emacs is started in GUI mode but not when started
-in text mode. The cursor still only actually blinks in GUI frames.
-
-** 'show-paren-mode' is now enabled by default.
-To go back to the previous behavior, customize the user option by the
-same name to nil.
-
-+++
-** New minor mode 'show-paren-local-mode'.
-It serves as a local counterpart for 'show-paren-mode', allowing you
-to toggle it separately in different buffers. To use it only in
-programming modes, for example, add the following to your init file:
-
-(add-hook 'prog-mode-hook #'show-paren-local-mode)
-
-
-* Changes in Specialized Modes and Packages in Emacs 28.1
-
-** Isearch and Replace
-
-+++
-*** Interactive regular expression search now uses faces for sub-groups.
-E.g., 'C-M-s foo-\([0-9]+\)' will now use the 'isearch-group-1' face
-on the part of the regexp that matches the sub-expression "[0-9]+".
-By default, there are two faces for sub-group highlighting, but you
-can define more faces whose names are of the form 'isearch-group-N',
-where N are successive numbers above 2.
-
-This is controlled by the 'search-highlight-submatches' user option.
-This feature is available only on terminals that have enough colors to
-distinguish between sub-expression highlighting.
-
-+++
-*** Interactive regular expression replace now uses faces for sub-groups.
-Like 'search-highlight-submatches', this is controlled by the new user option
-'query-replace-highlight-submatches'.
-
-+++
-*** New user option 'isearch-wrap-pause' defines how to wrap the search.
-There are choices to disable wrapping completely and to wrap immediately.
-When wrapping immediately, it consistently handles the numeric arguments
-of 'C-s' ('isearch-repeat-forward') and 'C-r' ('isearch-repeat-backward'),
-continuing with the remaining count after wrapping.
-
-+++
-*** New user option 'isearch-repeat-on-direction-change'.
-When this option is set, direction changes in Isearch move to another
-search match, if there is one, instead of moving point to the other
-end of the current match.
-
-*** New key 'M-s M-.' starts isearch looking for the thing at point.
-This key is bound to the new command 'isearch-forward-thing-at-point'.
-The new user option 'isearch-forward-thing-at-point' defines
-a list of symbols to try to get the "thing" at point. By default,
-the first element of the list is 'region' that tries to yank
-the currently active region to the search string.
-
-+++
-*** New user option 'lazy-highlight-no-delay-length'.
-Lazy highlighting of matches in Isearch now starts immediately if the
-search string is at least this long. 'lazy-highlight-initial-delay'
-still applies for shorter search strings, which avoids flicker in the
-search buffer due to too many matches being highlighted.
-
----
-*** The default 'search-whitespace-regexp' value has changed.
-This used to be "\\s-+", which meant that it was mode-dependent whether
-newlines were included in the whitespace set. This has now been
-changed to only match spaces and tab characters.
-
-** Dired
-
-+++
-*** New user option 'dired-kill-when-opening-new-dired-buffer'.
-If non-nil, Dired will kill the current buffer when selecting a new
-directory to display.
-
-+++
-*** Behavior change on 'dired-do-chmod'.
-As a security precaution, Dired's M command no longer follows symbolic
-links. Instead, it changes the symbolic link's own mode; this always
-fails on platforms where such modes are immutable.
-
----
-*** Behavior change on 'dired-clean-confirm-killing-deleted-buffers'.
-Previously, if 'dired-clean-up-buffers-too' was non-nil, and
-'dired-clean-confirm-killing-deleted-buffers' was nil, the buffers
-wouldn't be killed. This combination will now kill the buffers.
-
-+++
-*** New user option 'dired-switches-in-mode-line'.
-This user option controls how 'ls' switches are displayed in the mode
-line, and allows truncating them (to preserve space on the mode line)
-or showing them literally, either instead of, or in addition to,
-displaying "by name" or "by date" sort order.
-
-+++
-*** New user option 'dired-compress-directory-default-suffix'.
-This user option controls default suffix for compressing a directory.
-If it's nil, ".tar.gz" will be used. Refer to
-'dired-compress-files-alist' for a list of supported suffixes.
-
-+++
-*** New user option 'dired-compress-file-default-suffix'.
-This user option controls the default suffix for compressing files.
-If it's nil, ".gz" will be used. Refer to 'dired-compress-file-alist'
-for a list of supported suffixes.
-
----
-*** Broken and circular links are shown with the 'dired-broken-symlink' face.
-
----
-*** '=' ('dired-diff') will now put all backup files into the 'M-n' history.
-When using '=' on a file with backup files, the default file to use
-for diffing is the newest backup file. You can now use 'M-n' to quickly
-select a different backup file instead.
-
-+++
-*** New user option 'dired-maybe-use-globstar'.
-If set, enables globstar (recursive globbing) in shells that support
-this feature, but turn it off by default. This allows producing
-directory listings with files matching a wildcard in all the
-subdirectories of a given directory. The new variable
-'dired-enable-globstar-in-shell' lists which shells can have globstar
-enabled, and how to enable it.
-
-+++
-*** New user option 'dired-copy-dereference'.
-If set to non-nil, Dired will dereference symbolic links when copying.
-This can be switched off on a per-usage basis by providing
-'dired-do-copy' with a 'C-u' prefix.
-
----
-*** New user option 'dired-do-revert-buffer'.
-Non-nil reverts the destination Dired buffer after performing one
-of these operations: 'dired-do-copy', 'dired-do-rename',
-'dired-do-symlink', 'dired-do-hardlink'.
-
-*** New user option 'dired-mark-region'.
-This option affects all Dired commands that mark files. When non-nil
-and the region is active in Transient Mark mode, then Dired commands
-operate only on files in the active region. The values 'file' and
-'line' of this user option define the details of marking the file at
-the end of the region.
-
-*** State changing VC operations are supported in Dired.
-These operations are supported on files and directories via the new
-command 'dired-vc-next-action'.
-
-+++
-*** 'dired-jump' and 'dired-jump-other-window' moved from 'dired-x' to 'dired'.
-The 'dired-jump' and 'dired-jump-other-window' commands have been
-moved from the 'dired-x' package to 'dired'. The user option
-'dired-bind-jump' no longer has any effect and is now obsolete.
-The commands are now bound to 'C-x C-j' and 'C-x 4 C-j' by default.
-
-To get the old behavior of 'dired-bind-jump' back and unbind the above
-keys, add the following to your init file:
-
-(global-set-key "\C-x\C-j" nil)
-(global-set-key "\C-x4\C-j" nil)
-
----
-*** 'dired-query' now uses 'read-char-from-minibuffer'.
-Using it instead of 'read-char-choice' allows using 'C-x o'
-to switch to the help window displayed after typing 'C-h'.
-
-+++
-** New user option 'isearch-allow-motion'.
-When 'isearch-allow-motion' is set, the commands 'beginning-of-buffer',
-'end-of-buffer', 'scroll-up-command' and 'scroll-down-command', when
-invoked during I-search, move respectively to the first occurrence of
-the current search string in the buffer, the last one, the first one
-after the current window, and the last one before the current window.
-Additionally, users can change the meaning of other motion commands
-during I-search by using their 'isearch-motion' property. The
-option 'isearch-motion-changes-direction' controls whether the
-direction of the search changes after a motion command.
-
-+++
-** Emacs 28.1 comes with Org v9.5.
-See the file ORG-NEWS for user-visible changes in Org.
-
-** Outline
-
-+++
-*** New commands to cycle heading visibility.
-Typing 'TAB' on a heading line cycles the current section between
-"hide all", "subheadings", and "show all" states. Typing 'S-TAB'
-anywhere in the buffer cycles the whole buffer between "only top-level
-headings", "all headings and subheadings", and "show all" states.
-
-+++
-*** New user option 'outline-minor-mode-cycle'.
-This user option customizes 'outline-minor-mode', with the difference
-that 'TAB' and 'S-TAB' on heading lines cycle heading visibility.
-Typing 'TAB' on a heading line cycles the current section between
-"hide all", "subheadings", and "show all" states. Typing 'S-TAB' on a
-heading line cycles the whole buffer between "only top-level
-headings", "all headings and subheadings", and "show all" states.
-
----
-*** New user option 'outline-minor-mode-highlight'.
-This user option customizes 'outline-minor-mode'. It puts
-highlighting on heading lines using standard outline faces. This
-works well only when there are no conflicts with faces used by the
-major mode.
-
-** Ispell
-
-+++
-*** 'ispell-comments-and-strings' now accepts START and END arguments.
-These arguments default to active region when used interactively.
-
-+++
-*** New command 'ispell-comment-or-string-at-point'.
-
----
-*** New user option 'ispell-help-timeout'.
-This controls how long the ispell help (on the '?' key) is displayed.
-
-** Flyspell mode
-
-+++
-*** Corrections and actions menu can be optionally bound to 'mouse-3'.
-When Flyspell mode highlights a word as misspelled, you can click on
-it to display a menu of possible corrections and actions. You can now
-easily bind this menu to 'down-mouse-3' (usually the right mouse button)
-instead of 'mouse-2' (the default) by enabling 'context-menu-mode'.
-
----
-*** The current dictionary is now displayed in the minor mode lighter.
-Clicking the dictionary name changes the current dictionary.
-
-** Package
-
-*** The new NonGNU ELPA archive is enabled by default alongside GNU ELPA.
-Thus, packages on NonGNU ELPA will appear by default in the list shown
-by 'list-packages'.
-
----
-*** '/ s' ('package-menu-filter-by-status') changed parameter handling.
-The command was documented to take a comma-separated list of statuses
-to filter by, but instead it used the parameter as a regexp. The
-command has been changed so that it now works as documented, and
-checks statuses not as a regexp, but instead an exact match from the
-comma-separated list.
-
-+++
-*** New command 'package-browse-url' and keystroke 'w'.
-
-+++
-*** New commands to filter the package list.
-The filter commands are bound to the following keys:
-
-key binding
---- -------
-/ a package-menu-filter-by-archive
-/ d package-menu-filter-by-description
-/ k package-menu-filter-by-keyword
-/ N package-menu-filter-by-name-or-description
-/ n package-menu-filter-by-name
-/ s package-menu-filter-by-status
-/ v package-menu-filter-by-version
-/ m package-menu-filter-marked
-/ u package-menu-filter-upgradable
-/ / package-menu-filter-clear
-
-*** Option to automatically native-compile packages upon installation.
-Customize the user option 'package-native-compile' to enable automatic
-native compilation of packages when they are installed. That option
-is nil by default; if set non-nil, and if your Emacs was built with
-native-compilation support, each package will be natively compiled
-when it is installed, by invoking an asynchronous Emacs subprocess to
-run the native-compilation of the package files. (Be sure to leave
-Emacs running until these asynchronous subprocesses exit, or else the
-native-compilation will be aborted when you exit Emacs.)
-
----
-*** Column widths in 'list-packages' display can now be customized.
-See the new user options 'package-name-column-width',
-'package-version-column-width', 'package-status-column-width', and
-'package-archive-column-width'.
-
-** Info
-
----
-*** New user option 'Info-warn-on-index-alternatives-wrap'.
-This option affects what happens when using the ',' command after
-looking up an entry with 'i' in info buffers. If non-nil (the
-default), the ',' command will now display a warning when proceeding
-beyond the final index match, and tapping ',' once more will then take
-you to the first match.
-
-** Abbrev mode
-
-+++
-*** Emacs can now suggest to use an abbrev based on text you type.
-A new user option, 'abbrev-suggest', enables the new abbrev suggestion
-feature. When enabled, if a user manually types a piece of text that
-could have saved enough typing by using an abbrev, a hint will be
-displayed in the echo area, mentioning the abbrev that could have been
-used instead.
-
-** Bookmarks
-
-*** Bookmarks can now be targets for new tabs.
-When the bookmark.el library is loaded, a customize choice is added
-to 'tab-bar-new-tab-choice' for new tabs to show the bookmark list.
-
----
-*** The 'list-bookmarks' menu is now based on 'tabulated-list-mode'.
-The interactive bookmark list will now benefit from features in
-'tabulated-list-mode' like sorting columns or changing column width.
-
-Support for the optional "inline" header line, allowing for a header
-without using 'header-line-format', has been dropped. Consequently,
-the variables 'bookmark-bmenu-use-header-line' and
-'bookmark-bmenu-inline-header-height' are now declared obsolete.
-
----
-*** New user option 'bookmark-set-fringe-mark'.
-If non-nil, setting a bookmark will set a fringe mark on the current
-line, and jumping to a bookmark will also set this mark.
-
----
-*** New user option 'bookmark-menu-confirm-deletion'.
-In Bookmark Menu mode, Emacs by default does not prompt for
-confirmation when you type 'x' to execute the deletion of bookmarks
-that have been marked for deletion. However, if this new option is
-non-nil then Emacs will require confirmation with 'yes-or-no-p' before
-deleting.
-
-** Recentf
-
----
-*** The recentf files are no longer backed up.
-
----
-*** 'recentf-auto-cleanup' now repeats daily when set to a time string.
-When 'recentf-auto-cleanup' is set to a time string, it now repeats
-every day, rather than only running once after the mode is turned on.
-
-** Calc
-
----
-*** The behavior when doing forward-delete has been changed.
-Previously, using the 'C-d' command would delete the final number in
-the input field, no matter where point was. This has been changed to
-work more traditionally, with 'C-d' deleting the next character.
-Likewise, point isn't moved to the end of the string before inserting
-digits.
-
-+++
-*** Setting the word size to zero disables word clipping.
-The word size normally clips the results of certain bit-oriented
-operations such as shifts and bitwise XOR. A word size of zero, set
-by 'b w', makes the operation have effect on the whole argument values
-and the result is not truncated in any way.
-
----
-*** The '/' operator now has higher precedence in (La)TeX input mode.
-It no longer has lower precedence than '+' and '-'.
-
----
-*** Calc now marks its windows dedicated.
-The new user option 'calc-make-windows-dedicated' controls this. It
-is t by default; set to nil to get back the old behavior.
-
-** Calendar
-
-+++
-*** New user option 'calendar-time-zone-style'.
-If 'numeric', calendar functions (eg 'calendar-sunrise-sunset') that display
-time zones will use a form like "+0100" instead of "CET".
-
-** Imenu
-
-+++
-*** New user option 'imenu-max-index-time'.
-If creating the imenu index takes longer than specified by this
-option (default 5 seconds), imenu indexing is stopped.
-
-** ido
-
----
-*** Switching on 'ido-mode' now also overrides 'ffap-file-finder'.
-
----
-*** Killing virtual ido buffers interactively will make them go away.
-Previously, killing a virtual ido buffer with 'ido-kill-buffer' didn't
-do anything. This has now been changed, and killing virtual buffers
-with that command will remove the buffer from recentf.
-
-** So Long
-
----
-*** New 'so-long-predicate' function 'so-long-statistics-excessive-p'.
-It efficiently detects the presence of a long line anywhere in the
-buffer using 'buffer-line-statistics' (see above). This is now the
-default predicate (replacing 'so-long-detected-long-line-p').
-
----
-*** Default values 'so-long-threshold' and 'so-long-max-lines' increased.
-The values of these user options have been raised to 10000 bytes and 500
-lines respectively, to reduce the likelihood of false-positives when
-'global-so-long-mode' is enabled. The latter value is now only used
-by the old predicate, as the new predicate knows the longest line in
-the entire buffer.
-
----
-*** 'so-long-target-modes' now includes 'fundamental-mode' by default.
-This means that 'global-so-long-mode' will also process files which were
-not recognised. (This only has an effect if 'set-auto-mode' chooses
-'fundamental-mode'; buffers which are simply in 'fundamental-mode' by
-default are unaffected.)
-
----
-*** New user options to preserve modes and variables.
-The new options 'so-long-mode-preserved-minor-modes' and
-'so-long-mode-preserved-variables' allow specified mode and variable
-states to be maintained if 'so-long-mode' replaces the original major
-mode. By default, these new options support 'view-mode'.
-
-** Grep
-
-+++
-*** New user option 'grep-match-regexp' matches grep markers to highlight.
-Grep emits SGR ANSI escape sequences to color its output. The new
-user option 'grep-match-regexp' holds the regular expression to match
-the appropriate markers in order to provide highlighting in the source
-buffer. The user option can be customized to accommodate other
-grep-like tools.
-
----
-*** The 'lgrep' command now ignores directories.
-On systems where the grep command supports it, directories will be
-skipped.
-
-*** Commands that use 'grep-find' now follow symlinks for command-line args.
-This is because the default value of 'grep-find-template' now includes
-the 'find' option '-H'. Commands that use that variable, including
-indirectly via a call to 'xref-matches-in-directory', might be
-affected. In particular, there should be no need anymore to ensure
-any directory names on the 'find' command lines end in a slash.
-This change is for better compatibility with old versions of non-GNU
-'find', such as the one used on macOS.
-
----
-*** New utility function 'grep-file-at-point'.
-This returns the name of the file at point (if any) in 'grep-mode'
-buffers.
-
-** Shell
-
----
-*** New command in 'shell-mode': 'narrow-to-prompt'.
-This is bound to 'C-x n d' in 'shell-mode' buffers, and narrows to the
-command line under point (and any following output).
-
----
-*** New user option 'shell-has-auto-cd'.
-If non-nil, 'shell-mode' handles implicit "cd" commands, changing the
-directory if the command is a directory. Useful for shells like "zsh"
-that has this feature.
-
-** term-mode
-
----
-*** New user option 'term-scroll-snap-to-bottom'.
-By default, 'term' and 'ansi-term' will now recenter the buffer so
-that the prompt is on the final line in the window. Setting this new
-user option to nil inhibits this behavior.
-
----
-*** New user option 'term-set-terminal-size'
-If non-nil, the 'LINES' and 'COLUMNS' environment variables will be set
-based on the current window size. In previous versions of Emacs, this
-was always done (and that could lead to odd displays when resizing the
-window after starting). This variable defaults to nil.
-
----
-*** 'term-mode' now supports "bright" color codes.
-"Bright" ANSI color codes are now displayed using the color values
-defined in 'term-color-bright-*'. In addition, bold text with regular
-ANSI colors can be displayed as "bright" if 'ansi-color-bold-is-bright'
-is non-nil.
-
-** Eshell
-
----
-*** 'eshell-hist-ignoredups' can now also be used to mimic "erasedups" in bash.
-
----
-*** Environment variable 'INSIDE_EMACS' is now copied to subprocesses.
-Its value contains the result of evaluating '(format "%s,eshell"
-emacs-version)'. Other package names, like "tramp", could also be included.
-
----
-*** Eshell no longer re-initializes its keymap every call.
-This allows users to use (define-key eshell-mode-map ...) as usual.
-Some modules have their own minor mode now to account for these
-changes.
-
-*** Support for bookmark.el.
-The command `bookmark-set' (bound to `C-x r m') is now supported, and
-will create a bookmark that opens the current directory in Eshell.
-
-** Archive mode
-
----
-*** Archive Mode can now parse ".squashfs" files.
-
-*** Can now modify members of 'ar' archives.
-
-*** Display of summaries is unified between backends.
-
-*** New user option and command to control displayed columns.
-New user option 'archive-hidden-columns' and new command
-'archive-hideshow-column' let you control which columns are displayed
-and which are kept hidden.
-
----
-*** New command bound to 'C': 'archive-copy-file'.
-This command extracts the file at point and writes its data to a
-file.
-
-** browse-url
-
-*** Added support for custom URL handlers.
-There is a new variable 'browse-url-default-handlers' and a user
-option 'browse-url-handlers' being alists with '(REGEXP-OR-PREDICATE
-. FUNCTION)' entries allowing to define different browsing FUNCTIONs
-depending on the URL to be browsed. The variable is for default
-handlers provided by Emacs itself or external packages, the user
-option is for the user (and allows for overriding the default
-handlers).
-
-Formerly, one could do the same by setting
-'browse-url-browser-function' to such an alist. This usage is still
-supported but deprecated.
-
-*** Categorization of browsing commands into internal vs. external.
-All standard browsing commands such as 'browse-url-firefox',
-'browse-url-mail', or 'eww' have been categorized into internal (URL
-is browsed in Emacs) or external (an external application is spawned
-with the URL). This is done by adding a 'browse-url-browser-kind'
-symbol property to the browsing commands. With a new command
-'browse-url-with-browser-kind', an URL can explicitly be browsed with
-either an internal or external browser.
-
----
-*** Support for browsing of remote files.
-If a remote file is specified, a local temporary copy of that file is
-passed to the browser.
-
----
-*** Support for the conkeror browser is now obsolete.
-
----
-*** Support for the Mosaic browser has been removed.
-This support has been obsolete since 25.1.
-
-** Completion List Mode
-
-*** Improved navigation in the "*Completions*" buffer.
-New key bindings have been added to 'completion-list-mode': 'n' and
-'p' now navigate completions, and 'M-g M-c' switches to the
-minibuffer and back to the completion list buffer.
-
-+++
-** profiler.el
-The results displayed by 'profiler-report' now have the usage figures
-at the left hand side followed by the function name. This is intended
-to make better use of the horizontal space, in particular eliminating
-the truncation of function names. There is no way to get the former
-layout back.
-
-** Icomplete
-
----
-*** New user option 'icomplete-matches-format'.
-This allows controlling the current/total number of matches for the
-prompt prefix.
-
-+++
-*** New minor modes 'icomplete-vertical-mode' and 'fido-vertical-mode'.
-These modes modify Icomplete ('M-x icomplete-mode') and Fido ('M-x
-fido-mode'), to display completion candidates vertically instead of
-horizontally. In Icomplete, completions are rotated and selection
-kept at the top. In Fido, completions scroll like a typical dropdown
-widget. Both these new minor modes will turn on their non-vertical
-counterparts first, if they are not on already.
-
----
-*** Default value of 'icomplete-compute-delay' has been changed to 0.15 s.
-
----
-*** Default value of 'icomplete-max-delay-chars' has been changed to 2.
-
----
-*** Reduced blinking while completing the next completions set.
-Icomplete doesn't hide the hint with the previously computed
-completions anymore when compute delay is in effect, or the previous
-computation has been aborted by input. Instead it shows the previous
-completions until the new ones are ready.
-
----
-*** Change in meaning of 'icomplete-show-matches-on-no-input'.
-Previously, choosing a different completion with commands like 'C-.'
-and then hitting 'RET' would choose the default completion. Doing this
-will now choose the completion under point instead. Also when this option
-is nil, completions are not shown when the minibuffer reads a file name
-with initial input as the default directory.
-
-** Windmove
-
-+++
-*** New user options to customize windmove keybindings.
-These options include 'windmove-default-keybindings',
-'windmove-display-default-keybindings',
-'windmove-delete-default-keybindings',
-'windmove-swap-states-default-keybindings'.
-
-** Occur mode
-
-*** New bindings in occur-mode.
-The command 'next-error-no-select' is now bound to 'n' and
-'previous-error-no-select' is bound to 'p'.
-
-*** The new command 'recenter-current-error'.
-It is bound to 'l' in Occur or compilation buffers, and recenters the
-current displayed occurrence/error.
-
-*** Matches in target buffers are now highlighted as in 'compilation-mode'.
-The method of highlighting is specified by the user options
-'next-error-highlight' and 'next-error-highlight-no-select'.
-
----
-*** A fringe arrow in the "*Occur*" buffer indicates the selected match.
-
----
-*** Occur mode may use a different type for 'occur-target' property values.
-The value was previously always a marker set to the start of the first
-match on the line but can now also be a list of '(BEGIN . END)' pairs
-of markers delimiting each match on the line.
-This is a fully compatible change to the internal occur-mode
-implementation, and code creating their own occur-mode buffers will
-work as before.
-
-** Emacs Lisp mode
-
----
-*** The mode-line now indicates whether we're using lexical or dynamic scoping.
-
-+++
-*** A space between an open paren and a symbol changes the indentation rule.
-The presence of a space between an open paren and a symbol now is
-taken as a statement by the programmer that this should be indented
-as a data list rather than as a piece of code.
-
-** Lisp Mode
-
-*** New minor mode 'cl-font-lock-built-in-mode' for 'lisp-mode'.
-The mode provides refined highlighting of built-in functions, types,
-and variables.
-
----
-*** Lisp mode now uses 'common-lisp-indent-function'.
-To revert to the previous behavior,
-'(setq lisp-indent-function 'lisp-indent-function)' from 'lisp-mode-hook'.
-
-** Change Logs and VC
-
-+++
-*** 'vc-revert-show-diff' now has a third possible value: 'kill'.
-If this user option is 'kill', then the diff buffer will be killed
-after the 'vc-revert' action instead of buried.
-
-*** More VC commands can be used from non-file buffers.
-The relevant commands are those that don't change the VC state.
-The non-file buffers which can use VC commands are those that have
-their 'default-directory' under VC.
-
-*** New command 'vc-dir-root' uses the root directory without asking.
-
----
-*** New face 'log-view-commit-body'.
-This is used when expanding commit messages from 'vc-print-root-log'
-and similar commands.
-
----
-*** New faces for 'vc-dir' buffers.
-Those are: 'vc-dir-header', 'vc-dir-header-value', 'vc-dir-directory',
-'vc-dir-file', 'vc-dir-mark-indicator', 'vc-dir-status-warning',
-'vc-dir-status-edited', 'vc-dir-status-up-to-date',
-'vc-dir-status-ignored'.
-
----
-*** The responsible VC backend is now the most specific one.
-'vc-responsible-backend' loops over the backends in
-'vc-handled-backends' to determine which backend is responsible for a
-specific (unregistered) file. Previously, the first matching backend
-was chosen, but now the one with the most specific path is chosen (in
-case there's a directory handled by one backend inside another).
-
-*** New commands 'vc-dir-mark-registered-files' (bound to '* r') and
-'vc-dir-mark-unregistered-files'.
-
-*** Support for bookmark.el.
-Bookmark locations can refer to VC directory buffers.
-
----
-*** New user option 'vc-hg-create-bookmark'.
-It controls whether a bookmark or branch will be created when you
-invoke 'C-u C-x v s' ('vc-create-tag').
-
----
-*** 'vc-hg' now uses 'hg summary' to populate extra 'vc-dir' headers.
-
----
-*** New user option 'vc-git-revision-complete-only-branches'.
-If non-nil, only branches and remotes are considered when doing
-completion over Git branch names. The default is nil, which causes
-tags to be considered as well.
-
----
-*** New user option 'vc-git-log-switches'.
-String or list of strings specifying switches for Git log under VC.
-
-** Gnus
-
-+++
-*** New user option 'gnus-topic-display-predicate'.
-This can be used to inhibit the display of some topics completely.
-
-+++
-*** nnimap now supports the oauth2.el library.
-
-+++
-*** New Summary buffer sort options for extra headers.
-The extra header sort option ('C-c C-s C-x') prompts for a header
-and fails if no sort function has been defined. Sorting by
-Newsgroups ('C-c C-s C-u') has been pre-defined.
-
-+++
-*** The '#' command in the Group and Summary buffer now toggles,
-instead of sets, the process mark.
-
-+++
-*** New user option 'gnus-process-mark-toggle'.
-If non-nil (the default), the '#' command in the Group and Summary
-buffers will toggle, instead of set, the process mark.
-
-
-+++
-*** New user option 'gnus-registry-register-all'.
-If non-nil (the default), create registry entries for all messages.
-If nil, don't automatically create entries, they must be created
-manually.
-
-+++
-*** New user options to customise the summary line specs "%[" and "%]".
-Four new options introduced in customisation group
-'gnus-summary-format'. These are 'gnus-sum-opening-bracket',
-'gnus-sum-closing-bracket', 'gnus-sum-opening-bracket-adopted', and
-'gnus-sum-closing-bracket-adopted'. Their default values are "[", "]",
-"<", ">" respectively. These options control the appearance of "%["
-and "%]" specs in the summary line format. "%[" will normally display
-the value of 'gnus-sum-opening-bracket', but can also be
-'gnus-sum-opening-bracket-adopted' for the adopted articles. "%]" will
-normally display the value of 'gnus-sum-closing-bracket', but can also
-be 'gnus-sum-closing-bracket-adopted' for the adopted articles.
-
-+++
-*** New user option 'gnus-paging-select-next'.
-This controls what happens when using commands like 'SPC' and 'DEL' to
-page the current article. If non-nil (the default), go to the
-next/prev article, but if nil, do nothing at the end/start of the article.
-
-+++
-*** New gnus-search library.
-A new unified search syntax which can be used across multiple
-supported search engines. Set 'gnus-search-use-parsed-queries' to
-non-nil to enable.
-
-+++
-*** New value for user option 'smiley-style'.
-Smileys can now be rendered with emojis instead of small images when
-using the new 'emoji' value in 'smiley-style'.
-
-+++
-*** New user option 'gnus-agent-eagerly-store-articles'.
-If non-nil (which is the default), the Gnus Agent will store all read
-articles in the Agent cache.
-
-+++
-*** New user option 'gnus-global-groups'.
-Gnus handles private groups differently from public (i.e., NNTP-like)
-groups. Most importantly, Gnus doesn't download external images from
-mail-like groups. This can be overridden by putting group names in
-'gnus-global-groups': Any group present in that list will be treated
-like a public group.
-
-+++
-*** New scoring types for the Date header.
-You can now score based on the relative age of an article with the new
-'<' and '>' date scoring types.
-
-+++
-*** User-defined scoring is now possible.
-The new type is 'score-fn'. More information in the Gnus manual node
-"(gnus) Score File Format".
-
-+++
-*** New backend 'nnselect'.
-The newly added 'nnselect' backend allows creating groups from an
-arbitrary list of articles that may come from multiple groups and
-servers. These groups generally behave like any other group: they may
-be ephemeral or persistent, and allow article marking, moving,
-deletion, etc. 'nnselect' groups may be created like any other group,
-but there are three convenience functions for the common case of
-obtaining the list of articles as a result of a search:
-'gnus-group-make-search-group' ('G g') that will prompt for an 'nnir'
-search query and create a persistent group for that search;
-'gnus-group-read-ephemeral-search-group' ('G G') that will prompt for
-an 'nnir' search query and create an ephemeral group for that search;
-and 'gnus-summary-make-group-from-search' ('C-c C-p') that will create
-a persistent group with the search parameters of a current ephemeral
-search group.
-
-As part of this addition, the user option 'nnir-summary-line-format'
-has been removed; its functionality is now available directly in the
-'gnus-summary-line-format' specs '%G' and '%g'. The user option
-'gnus-refer-thread-use-nnir' has been renamed to
-'gnus-refer-thread-use-search'.
-
-+++
-*** New user option 'gnus-dbus-close-on-sleep'.
-On systems with D-Bus support, it is now possible to register a signal
-to close all Gnus servers before the system sleeps.
-
-+++
-*** The key binding of 'gnus-summary-search-article-forward' has changed.
-This command was previously on 'M-s' and shadowed the global 'M-s'
-search prefix. The command has now been moved to 'M-s M-s'. (For
-consistency, the 'M-s M-r' key binding has been added for the
-'gnus-summary-search-article-backward' command.)
-
----
-*** The value of "all" in the 'large-newsgroup-initial' group parameter
changes.
-It was previously nil, which didn't work, because nil is
-indistinguishable from not being present. The new value for "all" is
-the symbol 'all'.
-
-+++
-*** The name of dependent Gnus sessions has changed from "slave" to "child".
-The names of the commands 'gnus-slave', 'gnus-slave-no-server' and
-'gnus-slave-unplugged' have changed to 'gnus-child',
-'gnus-child-no-server' and 'gnus-child-unplugged' respectively.
-
-+++
-*** The 'W Q' summary mode command now takes a numerical prefix to
-allow adjusting the fill width.
-
-+++
-*** New variable 'mm-inline-font-lock'.
-This variable is supposed to be bound by callers to determine whether
-inline MIME parts (that support it) are supposed to be font-locked or
-not.
-
-** Message
-
----
-*** Respect 'message-forward-ignored-headers' more.
-Previously, this user option would not be consulted if
-'message-forward-show-mml' was nil and forwarding as MIME.
-
-+++
-*** New user option 'message-forward-included-mime-headers'.
-This is used when forwarding messages as MIME, but not using MML.
-
-+++
-*** Message now supports the OpenPGP header.
-To generate these headers, add the new function
-'message-add-openpgp-header' to 'message-send-hook'. The header will
-be generated according to the new 'message-openpgp-header' user
-option.
-
----
-*** A change to how "Mail-Copies-To: never" is handled.
-If a user has specified "Mail-Copies-To: never", and Message was asked
-to do a "wide reply", some other arbitrary recipient would end up in
-the resulting "To" header, while the remaining recipients would be put
-in the "Cc" header. This is somewhat misleading, as it looks like
-you're responding to a specific person in particular. This has been
-changed so that all the recipients are put in the "To" header in these
-instances.
-
-+++
-*** New command to start Emacs in Message mode to send an email.
-Emacs can be defined as a handler for the "x-scheme-handler/mailto"
-MIME type with the following command: "emacs -f message-mailto %u".
-An "emacs-mail.desktop" file has been included, suitable for
-installing in desktop directories like "/usr/share/applications" or
-"~/.local/share/applications".
-Clicking on a 'mailto:' link in other applications will then open
-Emacs with headers filled out according to the link, e.g.
-"mailto:larsi@gnus.org?subject=This+is+a+test";. If you prefer
-emacsclient, use "emacsclient -e '(message-mailto "%u")'"
-or "emacsclient-mail.desktop".
-
----
-*** Change to default value of 'message-draft-headers' user option.
-The 'Date' symbol has been removed from the default value, meaning that
-draft or delayed messages will get a date reflecting when the message
-was sent. To restore the original behavior of dating a message
-from when it is first saved or delayed, add the symbol 'Date' back to
-this user option.
-
-+++
-*** New command to take screenshots.
-In Message mode buffers, the 'C-c C-p' ('message-insert-screenshot')
-command has been added. It depends on using an external program to
-take the actual screenshot, and defaults to "ImageMagick import".
-
-** Smtpmail
-
-+++
-*** smtpmail now supports using the oauth2.el library.
-
-+++
-*** New user option 'smtpmail-store-queue-variables'.
-If non-nil, SMTP variables will be stored together with the queued
-messages, and will then be used when sending with
-'M-x smtpmail-send-queued-mail'.
-
-+++
-*** Allow direct selection of smtp authentication mechanism.
-A server entry retrieved by auth-source can request a desired smtp
-authentication mechanism by setting a value for the key 'smtp-auth'.
-
-** ElDoc
-
-+++
-*** New user option 'eldoc-echo-area-display-truncation-message'.
-If non-nil (the default), eldoc will display a message saying
-something like "(Documentation truncated. Use `M-x eldoc-doc-buffer'
-to see rest)" when a message has been truncated. If nil, truncated
-messages will be marked with just "..." at the end.
-
-+++
-*** New hook 'eldoc-documentation-functions'.
-This hook is intended to be used for registering doc string functions.
-These functions don't need to produce the doc string right away, they
-may arrange for it to be produced asynchronously. The results of all
-doc string functions are accessible to the user through the user
-option 'eldoc-documentation-strategy'.
-
-*** New hook 'eldoc-display-functions'.
-This hook is intended to be used for displaying doc strings. The
-functions receive the doc string composed according to
-'eldoc-documentation-strategy' and are tasked with displaying it to
-the user. Examples of such functions would use the echo area, a
-separate buffer, or a tooltip.
-
-+++
-*** New user option 'eldoc-documentation-strategy'.
-The built-in choices available for this user option let users compose
-the results of 'eldoc-documentation-functions' in various ways, even
-if some of those functions are synchronous and some asynchronous.
-The user option replaces 'eldoc-documentation-function', which is now
-obsolete.
-
-*** 'eldoc-echo-area-use-multiline-p' is now handled by ElDoc.
-The user option 'eldoc-echo-area-use-multiline-p' is now handled
-by the ElDoc library itself. Functions in
-'eldoc-documentation-functions' don't need to worry about consulting
-it when producing a doc string.
-
-** Tramp
-
-+++
-*** New connection method "mtp".
-It allows accessing media devices like cell phones, tablets or
-cameras.
-
-+++
-*** New connection method "sshfs".
-It allows accessing remote files via a file system mounted with
-'sshfs'.
-
-+++
-*** Tramp supports SSH authentication via a hardware security key now.
-This requires at least OpenSSH 8.2, and a FIDO U2F compatible
-security key, like yubikey, solokey, or nitrokey.
-
-+++
-*** Trashed remote files are moved to the local trash directory.
-All remote files that are trashed are moved to the local trash
-directory, except remote encrypted files, which are always deleted.
-
-+++
-*** New command 'tramp-crypt-add-directory'.
-This command marks a remote directory to contain only encrypted files.
-See the "(tramp) Keeping files encrypted" node of the Tramp manual for
-details. This feature is experimental.
-
-+++
-*** Support of direct asynchronous process invocation.
-When Tramp connection property "direct-async-process" is set to
-non-nil for a given connection, 'make-process' and 'start-file-process'
-calls are performed directly as in "ssh ... <command>". This avoids
-initialization performance penalties. See the "(tramp) Improving
-performance of asynchronous remote processes" node of the Tramp manual
-for details, and also for a discussion or restrictions. This feature
-is experimental.
-
-+++
-*** New user option 'tramp-debug-to-file'.
-When non-nil, this user option instructs Tramp to mirror the debug
-buffer to a file under the "/tmp/" directory. This is useful, if (in
-rare cases) Tramp blocks Emacs, and we need further debug information.
-
-+++
-*** Tramp supports lock files now.
-In order to deactivate this, set user option
-'remote-file-name-inhibit-locks' to t.
-
-+++
-*** Writing sensitive data locally requires confirmation.
-Writing auto-save, backup or lock files to the local temporary
-directory must be confirmed. In order to suppress this confirmation,
-set user option 'tramp-allow-unsafe-temporary-files' to t.
-
-+++
-*** 'make-directory' of a remote directory honors the default file modes.
-
-** gdb-mi
-
-*** New user option 'gdb-registers-enable-filter'.
-If non-nil, apply a register filter based on
-'gdb-registers-filter-pattern-list'.
-
-+++
-*** gdb-mi can now save and restore window configurations.
-Use 'gdb-save-window-configuration' to save window configuration to a
-file and 'gdb-load-window-configuration' to load from a file. These
-commands can also be accessed through the menu bar under "Gud =>
-GDB-Windows". 'gdb-default-window-configuration-file', when non-nil,
-is loaded when GDB starts up.
-
-+++
-*** gdb-mi can now restore window configuration after quitting.
-Set 'gdb-restore-window-configuration-after-quit' to non-nil and Emacs
-will remember the window configuration before GDB started and restore
-it after GDB quits. A toggle button is also provided under "Gud =>
-GDB-Windows" menu item.
-
-+++
-*** gdb-mi now has a better logic for displaying source buffers.
-Now GDB only uses one source window to display source file by default.
-Customize 'gdb-max-source-window-count' to use more than one window.
-Control source file display by 'gdb-display-source-buffer-action'.
-
-+++
-*** The default value of 'gdb-mi-decode-strings' is now t.
-This means that the default coding-system is now used to decode strings
-and source file names from GDB.
-
-** Compilation mode
-
----
-*** New function 'ansi-color-compilation-filter'.
-This function is meant to be used in 'compilation-filter-hook'.
-
----
-*** New user option 'ansi-color-for-compilation-mode'.
-This controls what 'ansi-color-compilation-filter' does.
-
-*** Regexp matching of messages is now case-sensitive by default.
-The variable 'compilation-error-case-fold-search' can be set for
-case-insensitive matching of messages when the old behavior is
-required, but the recommended solution is to use a correctly matching
-regexp instead.
-
----
-*** New user option 'compilation-search-all-directories'.
-When doing parallel builds, directories and compilation errors may
-arrive in the "*compilation*" buffer out-of-order. If this option is
-non-nil (the default), Emacs will now search backwards in the buffer
-for any directory the file with errors may be in. If nil, this won't
-be done (and this restores how this previously worked).
-
----
-*** Messages from ShellCheck are now recognized.
-
----
-*** Messages from Visual Studio that mention column numbers are now recognized.
-
-** Hi Lock mode
-
----
-*** Matching in 'hi-lock-mode' can be case-sensitive.
-The matching is case-sensitive when a regexp contains upper case
-characters and 'search-upper-case' is non-nil. 'highlight-phrase'
-also uses 'search-whitespace-regexp' to substitute spaces in regexp
-search.
-
----
-*** The default value of 'hi-lock-highlight-range' was enlarged.
-The new default value is 2000000 (2 megabytes).
-
-** Whitespace mode
-
-+++
-*** New style 'missing-newline-at-eof'.
-If present in 'whitespace-style' (as it is by default), the final
-character in the buffer will be highlighted if the buffer doesn't end
-with a newline.
-
----
-*** The default 'whitespace-enable-predicate' predicate has changed.
-It used to check elements in the list version of
-'whitespace-global-modes' with 'eq', but now uses 'derived-mode-p'.
-
-** Texinfo
-
----
-*** New user option 'texinfo-texi2dvi-options'.
-This is used when invoking 'texi2dvi' from 'texinfo-tex-buffer'.
-
----
-*** New commands for moving in and between environments.
-An "environment" is something that ends with '@end'. The commands are
-'C-c C-c C-f' (next end), 'C-c C-c C-b' (previous end),
-'C-c C-c C-n' (next start) and 'C-c C-c C-p' (previous start), as well
-as 'C-c .', which will alternate between the start and the end of the
-current environment.
-
-** Rmail
-
----
-*** New user option 'rmail-re-abbrevs'.
-Its default value matches localized abbreviations of the "reply"
-prefix on the Subject line in various languages.
-
----
-*** New user option 'shr-offer-extend-specpdl'.
-If this is nil, rendering of HTML in the email message body that
-requires to enlarge 'max-specpdl-size', the number of Lisp variable
-bindings, will be aborted, and Emacs will not ask you whether to
-enlarge 'max-specpdl-size' to complete the rendering. The default is
-t, which preserves the original behavior.
-
----
-*** New user option 'rmail-show-message-set-modified'.
-If set non-nil, showing an unseen message will set the Rmail buffer's
-modified flag. The default is nil, to preserve the old behavior.
-
-** CC Mode
-
-+++
-*** Added support for Doxygen documentation style.
-'doxygen' is now a valid 'c-doc-comment-style' which recognises all
-comment styles supported by Doxygen (namely '///', '//!', '/** … */'
-and '/*! … */'. 'gtkdoc' remains the default for C and C++ modes; to
-use 'doxygen' by default one might evaluate:
-
- (setq-default c-doc-comment-style
- '((java-mode . javadoc)
- (pike-mode . autodoc)
- (c-mode . doxygen)
- (c++-mode . doxygen)))
-
-or use it in a custom 'c-style'.
-
-+++
-*** Added support to line up '?' and ':' of a ternary operator.
-The new 'c-lineup-ternary-bodies' function can be used as a lineup
-function to align question mark and colon which are part of a ternary
-operator ('?:'). For example:
-
- return arg % 2 == 0 ? arg / 2
- : (3 * arg + 1);
-
-To enable, add it to appropriate entries in 'c-offsets-alist', e.g.:
-
- (c-set-offset 'arglist-cont '(c-lineup-ternary-bodies
- c-lineup-gcc-asm-reg))
- (c-set-offset 'arglist-cont-nonempty '(c-lineup-ternary-bodies
- c-lineup-gcc-asm-reg
- c-lineup-arglist))
- (c-set-offset 'statement-cont '(c-lineup-ternary-bodies +))
-
-** Images
-
----
-*** You can explicitly specify base_uri for svg images.
-':base-uri' image property can be used to explicitly specify base_uri
-for embedded images into svg. ':base-uri' is supported for both file
-and data svg images.
-
-+++
-*** 'svg-embed-base-uri-image' added to embed images.
-'svg-embed-base-uri-image' can be used to embed images located
-relatively to 'file-name-directory' of the ':base-uri' svg image property.
-This works much faster then 'svg-embed'.
-
-+++
-*** New function 'image-cache-size'.
-This function returns the size of the current image cache, in bytes.
-
----
-*** Animated images stop automatically under high CPU pressure sooner.
-Previously, an animated image would stop animating if any single image
-took more than two seconds to display. The new algorithm maintains a
-decaying average of delays, and if this number gets too high, the
-animation is stopped.
-
-+++
-*** The 'n' and 'p' commands (next/previous image) now respect Dired order.
-These commands would previously display the next/previous image in
-lexicographic order, but will now find the "parent" Dired buffer and
-select the next/previous image file according to how the files are
-sorted there. The commands have also been extended to work when the
-"parent" buffer is an archive mode (i.e., zip file or the like) or tar
-mode buffer.
-
----
-*** 'image-converter' is now restricted to formats in 'auto-mode-alist'.
-When using external image converters, the external program is queried
-for what formats it supports. This list may contain formats that are
-problematic in some contexts (like PDFs), so this list is now filtered
-based on 'auto-mode-alist'. Only file names that map to 'image-mode'
-are now supported.
-
----
-*** The background and foreground of images now default to face colors.
-When an image doesn't specify a foreground or background color, Emacs
-now uses colors from the face used to draw the surrounding text
-instead of the frame's default colors.
-
-To load images with the default frame colors use the ':foreground' and
-':background' image attributes, for example:
-
- (create-image "filename" nil nil
- :foreground (face-attribute 'default :foreground)
- :background (face-attribute 'default :background))
-
-This change only affects image types that support foreground and
-background colors or transparency, such as xbm, pbm, svg, png and gif.
-
-+++
-*** Image smoothing can now be explicitly enabled or disabled.
-Smoothing applies a bilinear filter while scaling or rotating an image
-to prevent aliasing and other unwanted effects. The new image
-property ':transform-smoothing' can be set to t to force smoothing
-and nil to disable smoothing.
-
-The default behavior of smoothing on down-scaling and not smoothing
-on up-scaling remains unchanged.
-
-+++
-*** New user option 'image-transform-smoothing'.
-This controls whether to use smoothing or not for an image. Values
-include nil (no smoothing), t (do smoothing) or a predicate function
-that's called with the image object and should return nil/t.
-
-+++
-*** SVG images now support user stylesheets.
-The ':css' image attribute can be used to override the default CSS
-stylesheet for an image. The default sets 'font-family' and
-'font-size' to match the current face, so an image with 'height="1em"'
-will match the font size in use where it is embedded.
-
-This feature relies on librsvg 2.48 or above being available.
-
-+++
-*** Image properties support 'em' sizes.
-Size image properties, for example ':height', ':max-height', etc., can
-be given a cons of the form '(SIZE . em)', where SIZE is an integer or
-float which is multiplied by the font size to calculate the image
-size, and 'em' is a symbol.
-
-** EWW
-
-+++
-*** New user option 'eww-use-browse-url'.
-This is a regexp that can be set to alter how links are followed in eww.
-
-+++
-*** New user option 'eww-retrieve-command'.
-This can be used to download data via an external command. If nil
-(the default), then 'url-retrieve' is used. When 'sync', then
-'url-retrieve-synchronously' is used.
-
-+++
-*** New Emacs command line convenience command.
-The 'eww-browse' command has been added, which allows you to register
-Emacs as a MIME handler for "text/x-uri", and will call 'eww' on the
-supplied URL. Usage example: "emacs -f eww-browse https://gnu.org";.
-
-+++
-*** 'eww-download-directory' will now use the XDG location, if defined.
-However, if "~/Downloads/" already exists, that will continue to be
-used.
-
----
-*** The command 'eww-follow-link' now supports custom mailto handlers.
-The function that is invoked when clicking on or otherwise following a
-'mailto:' link in an EWW buffer can now be customized. For more
-information, see the related entry about 'shr-browse-url' above.
-
----
-*** Support for bookmark.el.
-The command `bookmark-set' (bound to `C-x r m') is now supported, and
-will create a bookmark that opens the current URL in EWW.
-
-** SHR
-
----
-*** The command 'shr-browse-url' now supports custom mailto handlers.
-Clicking on or otherwise following a 'mailto:' link in a HTML buffer
-rendered by SHR previously invoked the command 'browse-url-mailto'.
-This is still the case by default, but if you customize
-'browse-url-mailto-function' or 'browse-url-handlers' to call some
-other function, it will now be called instead of the default.
-
-+++
-*** New user option 'shr-max-width'.
-If this user option is non-nil, and 'shr-width' is nil, then SHR will
-use the value of 'shr-max-width' to limit the width of the rendered
-HTML. The default is 120 characters, so even if you have very wide
-frames, HTML text will be rendered more narrowly, which usually leads
-to a more readable text. Customize it to nil to get the previous
-behavior of rendering as wide as the 'window-width' allows. If
-'shr-width' is non-nil, it overrides this option.
-
----
-*** New faces for heading elements.
-Those are 'shr-h1', 'shr-h2', 'shr-h3', 'shr-h4', 'shr-h5', 'shr-h6'.
-
-** Project
-
-*** New user option 'project-vc-merge-submodules'.
-
-*** Project commands now have their own history.
-Previously used project directories are now suggested by all commands
-that prompt for a project directory.
-
-+++
-*** New prefix keymap 'project-prefix-map'.
-Key sequences that invoke project-related commands start with the
-prefix 'C-x p'. Type "C-x p C-h" to show the full list.
-
-+++
-*** New commands 'project-dired', 'project-vc-dir', 'project-shell',
-'project-eshell'. These commands run Dired/VC-Dir and Shell/Eshell in
-a project's root directory, respectively.
-
-+++
-*** New command 'project-compile'.
-This command runs compilation in the current project's root
-directory.
-
-+++
-*** New command 'project-switch-project'.
-This command lets you "switch" to another project and run a project
-command chosen from a dispatch menu.
-
-+++
-*** New commands 'project-shell-command' and 'project-async-shell-command'.
-These commands run 'shell-command' and 'async-shell-command' in a
-project's root directory, respectively.
-
-+++
-*** New user option 'project-list-file'.
-This specifies the file in which to save the list of known projects.
-
-+++
-*** New command 'project-remember-projects-under'.
-This command can automatically locate and index projects in a
-directory and optionally also its subdirectories, storing them in
-'project-list-file'.
-
-+++
-*** New commands 'project-forget-project' and 'project-forget-projects-under'.
-These command lets you interactively remove entries from the list of projects
-in 'project-list-file'.
-
-+++
-*** New command 'project-forget-zombie-projects'.
-This command detects indexed projects that have since been deleted,
-and removes them from the list of known projects in 'project-list-file'.
-
----
-*** 'project-find-file' now accepts non-existent file names.
-This is to allow easy creation of files inside some nested
-sub-directory.
-
-+++
-*** 'project-find-file' doesn't use the string at point as default input.
-Now it's only suggested as part of the "future history".
-
-+++
-*** New command 'project-find-dir' runs Dired in a directory inside project.
-
-** Xref
-
----
-*** Prefix arg of 'xref-goto-xref' quits the "*xref*" buffer.
-So typing 'C-u RET' in the "*xref*" buffer quits its window
-before navigating to the selected location.
-
-+++
-*** New user options to automatically show the first Xref match.
-The new user option 'xref-auto-jump-to-first-definition' controls the
-behavior of 'xref-find-definitions' and its variants, like
-'xref-find-definitions-other-window': if it's t or 'show', the first
-match is automatically displayed; if it's 'move', point in the
-"*xref*" buffer is automatically moved to the first match without
-displaying it.
-The new user option 'xref-auto-jump-to-first-xref' changes the
-behavior of Xref commands such as 'xref-find-references',
-'xref-find-apropos', and 'project-find-regexp', which are expected to
-display many matches that the user would like to
-visit. 'xref-auto-jump-to-first-xref' changes their behavior much in
-the same way as 'xref-auto-jump-to-first-definition' affects the
-"find-definitions" commands.
-
----
-*** New user options 'xref-search-program' and 'xref-search-program-alist'.
-So far 'grep' and 'ripgrep' are supported. 'ripgrep' seems to offer better
-performance in certain cases, in particular for case-insensitive
-searches.
-
-+++
-*** New commands 'xref-prev-group' and 'xref-next-group'.
-These commands are bound respectively to 'P' and 'N', and navigate to
-the first item of the previous or next group in the "*xref*" buffer.
-
----
-*** New alternative value for 'xref-show-definitions-function':
-'xref-show-definitions-completing-read'.
-
----
-*** The two existing alternatives for 'xref-show-definitions-function'
-have been renamed to have "proper" public names and documented
-('xref-show-definitions-buffer' and
-'xref-show-definitions-buffer-at-bottom').
-
-+++
-*** New command 'xref-quit-and-pop-marker-stack'.
-This command is bound to 'M-,' in "*xref*" buffers. This combination
-is easy to press semi-accidentally if the user wants to go back in the
-middle of choosing the exact definition to go to, and this should do
-TRT.
-
----
-*** New value 'project-relative' for 'xref-file-name-display'.
-If chosen, file names in "*xref*" buffers will be displayed relative
-to the 'project-root' of the current project, when available.
-
-+++
-*** The 'TAB' key binding in "*xref*" buffers is obsolete.
-Use 'C-u RET' instead. The 'TAB' binding in "*xref*" buffers is still
-supported, but we plan on removing it in a future version; at that
-time, the command 'xref-quit-and-goto-xref' will no longer have a key
-binding in 'xref--xref-buffer-mode-map'.
-
----
-*** New user option 'etags-xref-prefer-current-file'.
-When non-nil, matches for identifiers in the file visited by the
-current buffer will be shown first in the "*xref*" buffer.
-
-+++
-*** The etags Xref backend now honors 'tags-apropos-additional-actions'.
-You can customize it to augment the output of 'xref-find-apropos',
-like it affected the output of 'tags-apropos', which is obsolete since
-Emacs 25.1.
-
-** Battery
-
----
-*** UPower is now the default battery status backend when available.
-UPower support via the function 'battery-upower' was added in Emacs
-26.1, but was disabled by default. It is now the default value of
-'battery-status-function' when the system provides a UPower D-Bus
-service. The user options 'battery-upower-device' and
-'battery-upower-subscribe' control which power sources to query and
-whether to respond to status change notifications in addition to
-polling, respectively.
-
----
-*** A richer syntax can be used to format battery status information.
-The user options 'battery-mode-line-format' and
-'battery-echo-area-format' now support the full formatting syntax of
-the function 'format-spec' documented under node "(elisp) Custom Format
-Strings". The new syntax includes specifiers for padding and
-truncation, amongst other things.
-
-** bug-reference.el
-
----
-*** Bug reference mode uses auto-setup.
-If 'bug-reference-mode' or 'bug-reference-prog-mode' have been
-activated, their respective hook has been run, and both
-'bug-reference-bug-regexp' and 'bug-reference-url-format' are still
-not set, it tries to guess appropriate values for those two variables.
-There are three guessing mechanisms so far: based on version control
-information of the current buffer's file, based on
-newsgroup/mail-folder name and several news and mail message headers
-in Gnus buffers, and based on IRC channel and network in rcirc and ERC
-buffers. All the mechanisms are extensible with custom rules, see the
-variables 'bug-reference-setup-from-vc-alist',
-'bug-reference-setup-from-mail-alist', and
-'bug-reference-setup-from-irc-alist'.
-
-** HTML Mode
-
----
-*** A new skeleton for adding relative URLs has been added.
-It's bound to the 'C-c C-c f' keystroke, and prompts for a local file
-name.
-
-** Widget
-
-+++
-*** 'widget-choose' now supports menus in extended format.
-
----
-*** The 'editable-list' widget now supports moving items up and down.
-You can now move items up and down by deleting and then reinserting
-them, using the 'DEL' and 'INS' buttons respectively. This is useful
-in Custom buffers, for example, to change the order of the elements in
-a list.
-
-** Diff
-
----
-*** New face 'diff-changed-unspecified'.
-This is used to highlight "changed" lines (those marked with '!') in
-context diffs, when 'diff-use-changed-face' is non-nil.
-
----
-*** New 'diff-mode' font locking face 'diff-error'.
-This face is used for error messages from 'diff'.
-
-+++
-*** New command 'diff-refresh-hunk'.
-This new command (bound to 'C-c C-l') regenerates the current hunk.
-
-** thing-at-point
-
-+++
-*** New 'thing-at-point' target: 'existing-filename'.
-This is like 'filename', but is a full path, and is nil if the file
-doesn't exist.
-
-+++
-*** New 'thing-at-point' target: 'string'.
-If point is inside a string, it returns that string.
-
-+++
-*** New variable 'thing-at-point-provider-alist'.
-This allows mode-specific alterations to how 'thing-at-point' works.
-
----
-*** thing-at-point now respects fields.
-'thing-at-point' (and all functions that use it, like
-'symbol-at-point') will narrow to the current field (if any) before
-trying to identify the thing at point.
-
-*** New function 'thing-at-mouse'.
-
-** image-dired
-
----
-*** 'image-dired-mouse-toggle-mark' now toggles files in the active region.
-
-+++
-*** New user option 'image-dired-thumb-visible-marks'.
-If non-nil (the default), use 'image-dired-thumb-mark' to say what
-images are marked.
-
----
-*** New command 'image-dired-delete-marked'.
-
-** Flymake mode
-
-+++
-*** New command 'flymake-show-project-diagnostics'
-This lists all diagnostics for buffers in the currently active
-project. The listing is similar to the one obtained by
-'flymake-show-buffer-diagnostics', but adds a column for the
-project-relative file name. For backends which support it,
-'flymake-show-project-diagnostics' also lists diagnostics for files
-that have not yet been visited.
-
-+++
-*** New user options to customize Flymake's mode-line.
-The new user option 'flymake-mode-line-format' is a mix of strings and
-symbols like 'flymake-mode-line-title', 'flymake-mode-line-exception'
-and 'flymake-mode-line-counters'. The new user option
-'flymake-mode-line-counter-format' is a mix of strings and symbols
-like 'flymake-mode-line-error-counter',
-'flymake-mode-line-warning-counter' and 'flymake-mode-line-note-counter'.
-
-** Time
-
----
-*** 'display-time-world' has been renamed to 'world-clock'.
-'world-clock' creates a buffer with an updating time display using
-several time zones. It is hoped that the new names are more
-discoverable.
-
-The following commands have been renamed:
-
- 'display-time-world' to 'world-clock'
- 'display-time-world-mode' to 'world-clock-mode'
- 'display-time-world-display' to 'world-clock-display'
- 'display-time-world-timer' to 'world-clock-update'
-
-The following user options have been renamed:
-
- 'display-time-world-list' to 'world-clock-list'
- 'display-time-world-time-format' to 'world-clock-time-format'
- 'display-time-world-buffer-name' to 'world-clock-buffer-name'
- 'display-time-world-timer-enable' to 'world-clock-timer-enable'
- 'display-time-world-timer-second' to 'world-clock-timer-second'
-
-The old names are now obsolete.
-
----
-*** 'world-clock-mode' can no longer be turned on interactively.
-Use 'world-clock' to turn on that mode.
-
-** Python mode
-
----
-*** New user option 'python-forward-sexp-function'.
-This allows the user easier customization of whether to use block-based
-navigation or not.
-
----
-*** 'python-shell-interpreter' now defaults to python3 on systems with python3.
-
----
-*** 'C-c C-r' can now be used on arbitrary regions.
-The command previously extended the start of the region to the start
-of the line, but will now actually send the marked region, as
-documented.
-
-** Ruby Mode
-
----
-*** 'ruby-use-smie' is declared obsolete.
-SMIE is now always enabled and 'ruby-use-smie' only controls whether
-indentation is done using SMIE or with the old ad-hoc code.
-
----
-*** Indentation has changed when 'ruby-align-chained-calls' is non-nil.
-This previously used to align subsequent lines with the last sibling,
-but it now aligns with the first sibling (which is the preferred style
-in Ruby).
-
-** CPerl Mode
-
----
-*** New face 'perl-heredoc', used for heredoc elements.
-
----
-*** The command 'cperl-set-style' offers the new value "PBP".
-This value customizes Emacs to use the style recommended in Damian
-Conway's book "Perl Best Practices" for indentation and formatting
-of conditionals.
-
-** Perl mode
-
----
-*** New face 'perl-non-scalar-variable'.
-This is used to fontify non-scalar variables.
-
-** Octave Mode
-
-+++
-*** Line continuations in double-quoted strings now use a backslash.
-Typing 'C-M-j' (bound to 'octave-indent-new-comment-line') now follows
-the behavior introduced in Octave 3.8 of using a backslash as a line
-continuation marker within double-quoted strings, and an ellipsis
-everywhere else.
-
-+++
-** EasyPG
-GPG key servers can now be queried for keys with the
-'M-x epa-search-keys' command. Keys can then be added to your
-personal key ring.
-
-** Etags
-
-+++
-*** Etags now supports the Mercury programming language.
-See https://mercurylang.org.
-
-+++
-*** Etags command line option '--declarations' now has Mercury-specific
behavior.
-All Mercury declarations are tagged by default. However, for
-compatibility with 'etags' support for Prolog, predicates and
-functions appearing first in clauses will also be tagged if 'etags' is
-invoked with the '--declarations' command-line option.
-
-** Comint
-
-+++
-*** Support for OSC escape sequences.
-Adding the new 'comint-osc-process-output' to
-'comint-output-filter-functions' enables the interpretation of OSC
-("Operating System Command") escape sequences in comint buffers. By
-default, only OSC 8, for hyperlinks, and OSC 7, for directory
-tracking, are acted upon. Adding more entries to
-'comint-osc-handlers' allows a customized treatment of further escape
-sequences.
-
-+++
-*** 'comint-delete-output' can now save deleted text in the kill-ring.
-Interactively, 'C-u C-c C-o' triggers this new optional behavior.
-
-** ansi-color.el
-
----
-*** Colors are now defined by faces.
-ANSI SGR codes now have corresponding faces to describe their
-appearance, e.g. 'ansi-color-bold'.
-
----
-*** Support for "bright" color codes.
-"Bright" ANSI color codes are now displayed when applying ANSI color
-filters using the color values defined by the faces
-'ansi-color-bright-COLOR'. In addition, bold text with regular ANSI
-colors can be displayed as "bright" if 'ansi-color-bold-is-bright' is
-non-nil.
-
-** ERC
-
----
-*** NickServ passwords can now be retrieved from auth-source.
-The 'erc-use-auth-source-for-nickserv-password' user option enables
-querying auth-source for NickServ passwords. To enable this, add the
-following to your init file:
-
- (setq erc-use-auth-source-for-nickserv-password t)
-
----
-*** NickServ identification now prompts for password last.
-When 'erc-prompt-for-nickserv-password' is non-nil, the user used to
-be unconditionally prompted interactively for a password, regardless
-of the value of 'erc-nickserv-passwords', which was effectively
-ignored (same for the new
-'erc-use-auth-source-for-nickserv-password'). This limitation is now
-lifted, and the user is interactively prompted last, after the other
-identification methods have run.
-
----
-*** The '/ignore' command will now ask for a timeout to stop ignoring the user.
-Allowed inputs are seconds or ISO8601-like periods like "1h" or "4h30m".
-
----
-*** ERC now recognizes 'C-]' for italic text.
-Italic text is displayed in the new 'erc-italic-face'.
-
----
-*** erc-match.el now supports 'message' highlight type (not including the
nick).
-The 'erc-current-nick-highlight-type', 'erc-pal-highlight-type',
-'erc-fool-highlight-type', 'erc-keyword-highlight-type', and
-'erc-dangerous-host-highlight-type' user options now support a
-'message' type for highlighting the entire message but not the
-sender's nick.
-
----
-*** erc-status-sidebar.el is now part of ERC.
-The 'erc-status-sidebar' package which provides a HexChat-like
-activity overview sidebar for joined IRC channels is now part of ERC.
-
-+++
-*** erc-tls now supports specifying a TLS client certificate.
-The 'erc-tls' function has been updated to allow specifying a TLS
-client certificate for authentication, as an alternative to NickServ
-password-based authentication. This is referred to as "CertFP" (short
-for Certificate Fingerprint) by several IRC networks. See the Info
-node "(erc) Connecting" in the ERC manual for more details and
-examples on how to specify and use TLS client certificates with
-'erc-tls'.
-
----
-*** Add 'erc-track-select-mode-line-face' (obsoletes 'erc-track-find-face').
-The 'erc-track-find-face' function of the erc-track module has been
-declared obsolete and rewritten as 'erc-track-select-mode-line-face',
-with different expected arguments (the current and old faces are now
-separated) and clearer documentation.
-
----
-*** Add '/opme' and '/deopme' convenience commands.
-The new '/opme' convenience command asks ChanServ to set the operator
-status for the current nick in the current channel, and '/deopme'
-unsets it.
-
----
-*** Add '/wii' convenience command for whois with idle time.
-The new '/wii' convenience command calls the '/whois' command with the
-given nick as both arguments, which is useful for displaying the whois
-information for the nick along with idle time, even if the nick is on
-a different server than the one the current user is connected to.
-Using the given nick itself instead of the server it is connected to
-is not standardized, but is widely supported across IRC networks.
-
-** xwidget-webkit mode
-
----
-*** New xwidget commands.
-'xwidget-webkit-uri' (return the current URL), 'xwidget-webkit-title'
-(return the current title), and 'xwidget-webkit-goto-history' (goto a
-point in history).
-
----
-*** Pixel-based scrolling.
-The 'xwidget-webkit-scroll-up', 'xwidget-webkit-scroll-down' commands
-now supports scrolling arbitrary pixel values. It now treats the
-optional 2nd argument as the pixel values to scroll.
-
----
-*** New commands for scrolling.
-The new commands 'xwidget-webkit-scroll-up-line',
-'xwidget-webkit-scroll-down-line', 'xwidget-webkit-scroll-forward',
-'xwidget-webkit-scroll-backward' can be used to scroll webkit by the
-height of lines or width of chars.
-
----
-*** New user option 'xwidget-webkit-bookmark-jump-new-session'.
-When non-nil, use a new xwidget webkit session after bookmark jump.
-Otherwise, it will use 'xwidget-webkit-last-session'.
-
-** Checkdoc
-
----
-*** No longer warns about command substitutions by default.
-Checkdoc used to warn about "too many command substitutions" (as in
-"\\[foo-command]"), even if you only used ten of them in a docstring.
-On modern machines, you can have hundreds or thousands of command
-substitutions before it becomes a performance issue, so this warning
-is now disabled by default. To re-enable this warning, customize the
-user option 'checkdoc-max-keyref-before-warn'.
-
----
-*** New user option 'checkdoc-column-zero-backslash-before-paren'.
-Checkdoc warns if there is a left parenthesis in column zero of a
-documentation string. That warning can now be disabled by customizing
-this new user option to nil. This is useful if you don't expect
-your code to be edited with an Emacs older than version 27.1.
-
----
-*** Now checks the prompt format for 'yes-or-no-p'.
-In addition to verifying the format of the prompt for 'y-or-n-p',
-checkdoc will now check the format of 'yes-or-no-p'.
-
----
-*** New command 'checkdoc-dired'.
-This can be used to run checkdoc on files from a Dired buffer.
-
----
-*** No longer checks for "A-" modifiers.
-Checkdoc recommends usage of command substitutions ("\\[foo-command]")
-in favor of writing keybindings like "C-c f". It now no longer warns
-about the "A-" modifier as it is not used very much in practice, and
-this warning therefore mostly led to false positives.
-
-** Enriched mode
-
----
-*** 'C-a' is by default no longer bound to 'beginning-of-line-text'.
-This is so 'C-a' works as in other modes, and in particular holding
-Shift while typing 'C-a', i.e. 'C-S-a', will now highlight the text.
-
-** Gravatar
-
----
-*** New user option 'gravatar-service' for host to query for gravatars.
-Defaults to 'libravatar', with 'unicornify' and 'gravatar' as options.
-
-** MH-E mail handler for Emacs
-
-Functions and variables related to handling junk mail have been
-renamed to not associate color with sender quality.
-
-+++
-*** New names for mh-junk interactive functions.
-Function 'mh-junk-whitelist' is renamed 'mh-junk-allowlist'.
-Function 'mh-junk-blacklist' is renamed 'mh-junk-blocklist'.
-
-+++
-*** New binding for 'mh-junk-allowlist'.
-The key binding for 'mh-junk-allowlist' is changed from 'J w' to 'J a'.
-The old binding is supported but warns that it is obsolete.
-
-+++
-*** New names for some hooks.
-'mh-whitelist-msg-hook' is renamed 'mh-allowlist-msg-hook'.
-'mh-blacklist-msg-hook' is renamed 'mh-blocklist-msg-hook'.
-
-+++
-*** New names for some user options.
-User option 'mh-whitelist-preserves-sequences-flag' is renamed
-'mh-allowlist-preserves-sequences-flag'.
-
-+++
-*** New names for some faces.
-Face 'mh-folder-blacklisted' is renamed 'mh-folder-blocklisted'.
-Face 'mh-folder-whitelisted' is renamed 'mh-folder-allowlisted'.
-
-** Rcirc
-
-+++
-*** rcirc now supports SASL authentication.
-
----
-*** rcirc connects asynchronously.
-
----
-*** Integrate formatting into 'rcirc-send-string'.
-The function now accepts a variable number of arguments.
-
-+++
-*** Deprecate 'defun-rcirc-command' in favour of 'rcirc-define-command'.
-The new macro handles multiple and optional arguments.
-
----
-*** Add basic IRCv3 support.
-This includes support for the capabilities: 'server-time', 'batch',
-'message-ids', 'invite-notify', 'multi-prefix' and 'standard-replies'.
-
----
-*** Add mouse property support to 'rcirc-track-minor-mode'.
-
----
-*** Improve support for IRC markup codes.
-
----
-*** Check 'auth-sources' for server passwords.
-
-+++
-*** Implement repeated reconnection strategy.
-See 'rcirc-reconnect-attempts'.
-
-** MPC
-
----
-*** New command 'mpc-goto-playing-song'.
-This command, bound to 'o' in any 'mpc-mode' buffer, moves point to
-the currently playing song in the "*Songs*" buffer.
-
----
-*** New user option 'mpc-cover-image-re'.
-If non-nil, it is a regexp that should match a valid cover image.
-
-** Miscellaneous
-
----
-*** 'shell-script-mode' now supports 'outline-minor-mode'.
-The outline headings have lines that start with "###".
-
----
-*** fileloop will now skip missing files instead of signalling an error.
-
----
-*** 'tabulated-list-mode' can now restore original display order.
-Many commands (like 'C-x C-b') are derived from 'tabulated-list-mode',
-and that mode allows the user to sort on any column. There was
-previously no easy way to get back to the original displayed order
-after sorting, but giving a -1 numerical prefix to the sorting command
-will now restore the original order.
-
----
-*** 'M-left' and 'M-right' now move between columns in 'tabulated-list-mode'.
-
----
-*** New variable 'hl-line-overlay-priority'.
-This can be used to change the priority of the hl-line overlays.
-
-+++
-*** New command 'mailcap-view-file'.
-This command will open a viewer based on the file type, as determined
-by "~/.mailcap" and related files and variables.
-
----
-*** New user option 'remember-diary-regexp'.
-
----
-*** New user option 'remember-text-format-function'.
-
----
-*** New user option 'authinfo-hide-elements'.
-This can be set to nil to inhibit hiding passwords in ".authinfo" files.
-
----
-*** 'hexl-mode' scrolling commands now heed 'next-screen-context-lines'.
-Previously, 'hexl-scroll-down' and 'hexl-scroll-up' would scroll
-up/down an entire window, but they now work more like the standard
-scrolling commands.
-
----
-*** New user option 'bibtex-unify-case-function'.
-This new option allows the user to customize how case is converted
-when unifying entries.
-
----
-*** The user option 'bibtex-maintain-sorted-entries' now permits
-user-defined sorting schemes.
-
----
-*** New user option 'reveal-auto-hide'.
-If non-nil (the default), revealed text is automatically hidden when
-point leaves the text. If nil, the text is not hidden again. Instead
-'M-x reveal-hide-revealed' can be used to hide all the revealed text.
-
----
-*** New user option 'ffap-file-name-with-spaces'.
-If non-nil, 'find-file-at-point' and friends will try to guess more
-expansively to identify a file name with spaces. Default value is
-nil.
-
----
-*** Two new commands for centering in 'doc-view-mode'.
-The new commands 'doc-view-center-page-horizontally' (bound to 'c h')
-and 'doc-view-center-page-vertically' (bound to 'c v') center the page
-horizontally and vertically, respectively.
-
----
-*** 'tempo-define-template' can now re-assign templates to tags.
-Previously, assigning a new template to an already defined tag had no
-effect.
-
----
-*** The width of the buffer-name column in 'list-buffers' is now dynamic.
-The width now depends of the width of the window, but will never be
-wider than the length of the longest buffer name, except that it will
-never be narrower than 19 characters.
-
-+++
-*** New diary sexp 'diary-offset'.
-It offsets another diary sexp by a number of days. This is useful
-when for example your organization has a committee meeting two days
-after every monthly meeting which takes place on the third Thursday,
-or if you would like to attend a virtual meeting scheduled in a
-different timezone causing a difference in the date.
-
----
-*** The old non-SMIE indentation of 'sh-mode' has been removed.
-
----
-*** 'mspools-show' is now autoloaded.
-
----
-*** Loading dunnet.el in batch mode doesn't start the game any more.
-Instead you need to do "emacs -f dun-batch" to start the game in
-batch mode.
-
-
-* New Modes and Packages in Emacs 28.1
-
-+++
-** New transient mode 'repeat-mode' to allow shorter key sequences.
-You can type 'C-x u u' instead of 'C-x u C-x u' to undo many changes,
-'C-x o o' instead of 'C-x o C-x o' to switch several windows,
-'C-x { { } } ^ ^ v v' to resize the selected window interactively,
-'M-g n n p p' to navigate next-error matches. Any other key exits
-transient mode and then is executed normally. 'repeat-exit-key'
-defines an additional key to exit mode like 'isearch-exit' ('RET').
-The user option 'repeat-exit-timeout' specifies the number of
-seconds of idle time to break the repetition chain automatically.
-With 'repeat-keep-prefix' you can keep the prefix arg of the previous
-command. For example, this can help to reverse the window navigation
-direction with e.g. 'C-x o M-- o o'. Also it can help to set a new
-step with e.g. 'C-x { C-5 { { {', which will set the window resizing
-step to 5 columns.
-
----
-** New themes 'modus-vivendi' and 'modus-operandi'.
-These themes are designed to conform with the highest standard for
-color-contrast accessibility (WCAG AAA). You can load either of them
-using 'M-x customize-themes' or 'load-theme' from your init file.
-Consult the Modus Themes Info manual for more information on the user
-options they provide.
-
-** Dictionary mode
-This is a mode for searching a RFC 2229 dictionary server.
-'dictionary' opens a buffer for starting operations.
-'dictionary-search' performs a lookup for a word. It also supports a
-'dictionary-tooltip-mode' which performs a lookup of the word under
-the mouse in 'dictionary-tooltip-dictionary' (which must be customized
-first).
-
----
-** Lisp Data mode
-The new command 'lisp-data-mode' enables a major mode for buffers
-composed of Lisp symbolic expressions that do not form a computer
-program. The ".dir-locals.el" file is automatically set to use this
-mode, as are other data files produced by Emacs.
-
-+++
-** New global mode 'global-goto-address-mode'.
-This will enable 'goto-address-mode' in all buffers.
-
-** transient.el
-This library implements support for powerful keyboard-driven menus.
-Such menus can be used as simple visual command dispatchers. More
-complex menus take advantage of infix arguments, which are somewhat
-similar to prefix arguments, but are more flexible and discoverable.
-
-** hierarchy.el
-This library can create, query, navigate and display hierarchical
-structures.
-
----
-** New major mode for displaying the "etc/AUTHORS" file.
-This new 'etc-authors-mode' provides font-locking for displaying the
-"etc/AUTHORS" file from the Emacs distribution, and not much else.
+* Installation Changes in Emacs 29.1
-* Incompatible Editing Changes in Emacs 28.1
-
----
-** 'toggle-truncate-lines' now disables 'visual-line-mode'.
-This is for symmetry with 'visual-line-mode', which disables
-'truncate-lines'.
-
----
-** 'electric-indent-mode' now also indents inside strings and comments.
-(This only happens when indentation function also supports this.)
-
-To recover the previous behavior you can use:
-
- (add-hook 'electric-indent-functions
- (lambda (_) (if (nth 8 (syntax-ppss)) 'no-indent)))
-
----
-** The 'M-o' ('facemenu-keymap') global binding has been removed.
-To restore the old binding, say something like:
-
- (require 'facemenu)
- (define-key global-map "\M-o" 'facemenu-keymap)
- (define-key facemenu-keymap "\es" 'center-line)
- (define-key facemenu-keymap "\eS" 'center-paragraph)
-
-The last two lines are not strictly necessary if you don't care about
-having those two commands on the 'M-o' keymap; see the next section.
-
----
-** The 'M-o M-s' and 'M-o M-S' global bindings have been removed.
-Use 'M-x center-line' and 'M-x center-paragraph' instead. See the
-previous section for how to get back the old bindings. Alternatively,
-if you only want these two commands to have global bindings they had
-before, you can add the following to your init file:
-
- (define-key global-map "\M-o\M-s" 'center-line)
- (define-key global-map "\M-o\M-S" 'center-paragraph)
-
----
-** The 'M-o M-o' global binding has been removed.
-Use 'M-x font-lock-fontify-block' instead, or the new 'C-x x f'
-command, which updates the syntax highlighting in the current buffer.
-
----
-** The escape sequence '\e[29~' in Xterm is now mapped to 'menu'.
-Xterm sends this sequence for both 'F16' and 'Menu' keys
-It used to be mapped to 'print' but we couldn't find a terminal
-that uses this sequence for any kind of 'Print' key.
-This makes the Menu key (see https://en.wikipedia.org/wiki/Menu_key)
-work for 'context-menu-mode' in Xterm.
-
----
-** New user option 'xterm-store-paste-on-kill-ring'.
-If non-nil (the default), Emacs pushes pasted text onto the kill ring
-(if using an xterm-like terminal that supports bracketed paste).
-Setting this to nil inhibits that.
-
----
-** 'vc-print-branch-log' shows the change log from its root directory.
-It previously used to use the default directory.
-
----
-** 'project-shell' and 'shell' now use 'pop-to-buffer-same-window'.
-This is to keep the same behavior as Eshell.
-
----
-** In 'nroff-mode', 'center-line' is no longer bound to a key.
-The original key binding was 'M-s', which interfered with I-search,
-since the latter uses 'M-s' as a prefix key of the search prefix map.
-
----
-** In 'f90-mode', the backslash character ('\') no longer escapes.
-For about a decade, the backslash character has no longer had a
-special escape syntax in Fortran F90. To get the old behavior back,
-say something like:
-
- (modify-syntax-entry ?\\ "\\" f90-mode-syntax-table)
-
-+++
-** Setting 'fill-column' to nil is obsolete.
-This undocumented use of 'fill-column' is now obsolete. To disable
-auto filling, turn off 'auto-fill-mode' instead.
-
-For instance, you could add something like the following to your init
-file:
-
- (add-hook 'foo-mode-hook (lambda () (auto-fill-mode -1))
+* Startup Changes in Emacs 29.1
-* Incompatible Lisp Changes in Emacs 28.1
-
-+++
-** Emacs now prints a backtrace when signaling an error in batch mode.
-This makes debugging Emacs Lisp scripts run in batch mode easier. To
-get back the old behavior, set the new variable
-'backtrace-on-error-noninteractive' to a nil value.
-
----
-** Some floating-point numbers are now handled differently by the Lisp reader.
-In previous versions of Emacs, numbers with a trailing dot and an exponent
-were read as integers and the exponent ignored: 2.e6 was interpreted as the
-integer 2. Such numerals are now read as floats with the exponent included:
-2.e6 is now read as the floating-point value 2000000.0.
-That is, '(read-from-string "1.e3")' => '(1000.0 . 4)' now.
-
----
-** 'equal' no longer examines some contents of window configurations.
-Instead, it considers window configurations to be equal only if they
-are 'eq'. To compare contents, use 'compare-window-configurations'
-instead. This change helps fix a bug in 'sxhash-equal', which returned
-incorrect hashes for window configurations and some other objects.
-
-+++
-** The 'lexical-binding' local variable is always enabled.
-Previously, if 'enable-local-variables' was nil, a 'lexical-binding'
-local variable would not be heeded. This has now changed, and a file
-with a 'lexical-binding' cookie is always heeded. To revert to the
-old behavior, set 'permanently-enabled-local-variables' to nil.
-
-+++
-** '&rest' in argument lists must always be followed by a variable name.
-Omitting the variable name after '&rest' was previously tolerated in
-some cases but not consistently so; it could lead to crashes or
-outright wrong results. Since the utility was marginal at best, it is
-now an error to omit the variable.
-
----
-** 'kill-all-local-variables' has changed how it handles non-symbol hooks.
-The function is documented to eliminate all buffer-local bindings
-except variables with a 'permanent-local' property, or hooks that
-have elements with a 'permanent-local-hook' property. In addition, it
-would also keep lambda expressions in hooks sometimes. The latter has
-now been changed: The function will now also remove these.
-
-+++
-** Temporary buffers no longer run certain buffer hooks.
-The macros 'with-temp-buffer' and 'with-temp-file' no longer run the
-hooks 'kill-buffer-hook', 'kill-buffer-query-functions', and
-'buffer-list-update-hook' for the temporary buffers they create. This
-avoids slowing them down when a lot of these hooks are defined.
-
-+++
-** New face 'child-frame-border' and frame parameter
'child-frame-border-width'.
-The face and width of child frames borders can now be determined
-separately from those of normal frames. To minimize backward
-incompatibility, child frames without a 'child-frame-border-width'
-parameter will fall back to using 'internal-border-width'. However,
-the new 'child-frame-border' face does constitute a breaking change
-since child frames' borders no longer use the 'internal-border' face.
-
----
-** 'run-at-time' now tries harder to implement the t TIME parameter.
-If TIME is t, the timer runs at an integral multiple of REPEAT.
-(I.e., if given a REPEAT of 60, it'll run at 08:11:00, 08:12:00,
-08:13:00.) However, when a machine goes to sleep (or otherwise didn't
-get a time slot to run when the timer was scheduled), the timer would
-then fire every 60 seconds after the time the timer was fired. This
-has now changed, and the timer code now recomputes the integral
-multiple every time it runs, which means that if the laptop wakes at
-08:16:43, it'll fire at that time, but then at 08:17:00, 08:18:00...
-
----
-** 'parse-partial-sexp' now signals an error if TO is smaller than FROM.
-Previously, this would lead to the function interpreting FROM as TO and
-vice versa, which would be confusing when passing in OLDSTATE, which
-refers to the old state at FROM.
-
-+++
-** 'global-mode-string' constructs should end with a space.
-This was previously not formalized, which led to combinations of modes
-displaying data "smushed together" on the mode line.
-
-+++
-** 'overlays-in' now handles zero-length overlays slightly differently.
-Previously, zero-length overlays at the end of the buffer were included
-in the result (if the region queried for stopped at that position).
-The same was not the case if the buffer had been narrowed to exclude
-the real end of the buffer. This has now been changed, and
-zero-length overlays at 'point-max' are always included in the results.
-
----
-** 'replace-match' now runs modification hooks slightly later.
-The function is documented to leave point after the replacement text,
-but this was not always the case if a modification hook inserted text
-in front of the replaced text -- 'replace-match' would instead leave
-point where the end of the inserted text would have been before the
-hook ran. 'replace-match' now always leaves point after the
-replacement text.
-
-+++
-** 'completing-read-default' sets completion variables buffer-locally.
-'minibuffer-completion-table' and related variables are now set buffer-locally
-in the minibuffer instead of being set via a global let-binding.
-
----
-** XML serialization functions now reject invalid characters.
-Previously, 'xml-print' would produce invalid XML when given a string
-with characters that are not valid in XML (see
-https://www.w3.org/TR/xml/#charsets). Now it rejects such strings.
-
----
-** JSON
-
----
-*** JSON number parsing is now stricter.
-Numbers with a leading plus sign, leading zeros, or a missing integer
-component are now rejected by 'json-read' and friends. This makes
-them more compliant with the JSON specification and consistent with
-the native JSON parsing functions.
-
----
-*** JSON functions support the semantics of RFC 8259.
-The JSON functions 'json-serialize', 'json-insert',
-'json-parse-string', and 'json-parse-buffer' now implement some of the
-semantics of RFC 8259 instead of the earlier RFC 4627. In particular,
-these functions now accept top-level JSON values that are neither
-arrays nor objects.
-
----
-*** Some JSON encoding functions are now obsolete.
-The functions 'json-encode-number', 'json-encode-hash-table',
-'json-encode-key', and 'json-encode-list' are now obsolete.
-
-The first two are kept as aliases of 'json-encode', which should be
-used instead. Uses of 'json-encode-list' should be changed to call
-one of 'json-encode', 'json-encode-alist', 'json-encode-plist', or
-'json-encode-array' instead.
-
-+++
-*** Native JSON functions now signal an error if libjansson is unavailable.
-This affects 'json-serialize', 'json-insert', 'json-parse-string',
-and 'json-parse-buffer'. This can happen if Emacs was compiled with
-libjansson, but the DLL cannot be found and/or loaded by Emacs at run
-time. Previously, Emacs would display a message and return nil in
-these cases.
-
-+++
-** The use of positional arguments in 'define-minor-mode' is obsolete.
-These were actually rendered obsolete in Emacs 21 but were never
-marked as such.
-
----
-** 'pcomplete-ignore-case' is now an obsolete alias of
'completion-ignore-case'.
-
-+++
-** 'completions-annotations' face is not used when the caller puts own face.
-This affects the suffix specified by completion 'annotation-function'.
-
-+++
-** An active minibuffer now has major mode 'minibuffer-mode'.
-This is instead of the erroneous 'minibuffer-inactive-mode' it
-formerly had.
-
----
-** 'make-text-button' no longer modifies text properties of its first argument.
-When its first argument is a string, 'make-text-button' no longer
-modifies the string's text properties; instead, it uses and returns
-a copy of the string. This helps avoid trouble when strings are
-shared or constants.
-
-+++
-** Some properties from completion tables are now preserved.
-If 'minibuffer-allow-text-properties' is non-nil, doing completion
-over a table of strings with properties will no longer remove all the
-properties before returning. This affects things like 'completing-read'.
-
----
-** 'dns-query' now consistently uses Lisp integers to represent integers.
-Formerly it made an exception for integer components of SOA records,
-because SOA serial numbers can exceed fixnum ranges on 32-bit platforms.
-Emacs now supports bignums so this old glitch is no longer needed.
-
-+++
-** The '&define' keyword in an Edebug specification now disables backtracking.
-The implementation was buggy, and multiple '&define' forms in an '&or'
-form should be exceedingly rare. See the Info node "(elisp) Backtracking" in
-the Emacs Lisp reference manual for background.
-
-+++
-** The error 'ftp-error' belongs also to category 'remote-file-error'.
-
-+++
-** The WHEN argument of 'make-obsolete' and related functions is mandatory.
-The use of those functions without a WHEN argument was marked obsolete
-back in Emacs 23.1. The affected functions are: 'make-obsolete',
-'define-obsolete-function-alias', 'make-obsolete-variable',
-'define-obsolete-variable-alias'.
-
-+++
-** 'inhibit-nul-byte-detection' is renamed to 'inhibit-null-byte-detection'.
-
----
-** Some functions are no longer considered safe by 'unsafep':
-'replace-regexp-in-string', 'catch', 'throw', 'error', 'signal'
-and 'play-sound-file'.
-
----
-** 'sql-*-statement-starters' are no longer user options.
-These variables describe facts about the SQL standard and
-product-specific additions. There should be no need for users to
-customize them.
-
----
-** Some locale-related variables have been removed.
-The Lisp variables 'previous-system-messages-locale' and
-'previous-system-time-locale' have been removed, as they were created
-by mistake and were not useful to Lisp code.
-
----
-** Function 'lm-maintainer' is replaced with 'lm-maintainers'.
-The former is now declared obsolete.
-
-+++
-** 'facemenu.el' is no longer preloaded.
-To use functions/variables from the package, you now have to say
-'(require 'facemenu)' or similar.
-
----
-** 'facemenu-color-alist' is now obsolete, and is not used.
-
----
-** The variable 'keyboard-type' is obsolete and not dynamically scoped any
more.
-
-+++
-** The 'values' variable is now obsolete.
-Using it just contributes to the growth of the Emacs memory
-footprint.
-
----
-** The 'load-dangerous-libraries' variable is now obsolete.
-It was used to allow loading Lisp libraries compiled by XEmacs, a
-modified version of Emacs which is no longer actively maintained.
-This is no longer supported, and setting this variable has no effect.
-
-+++
-** The macro 'with-displayed-buffer-window' is now obsolete.
-Use macro 'with-current-buffer-window' with action alist entry 'body-function'.
-
----
-** The rfc2368.el library is now obsolete.
-Use rfc6068.el instead. The main difference is that
-'rfc2368-parse-mailto-url' and 'rfc2368-unhexify-string' assumed that
-the strings were all-ASCII, while 'rfc6068-parse-mailto-url' and
-'rfc6068-unhexify-string' parse UTF-8 strings.
-
----
-** The inversion.el library is now obsolete.
-
----
-** The metamail.el library is now obsolete.
-
-** Edebug changes
-
----
-*** 'get-edebug-spec' is obsolete, replaced by 'edebug-get-spec'.
-
-+++
-*** The spec operator ':name NAME' is obsolete, use '&name' instead.
-
-+++
-*** The spec element 'function-form' is obsolete, use 'form' instead.
-
-+++
-*** New function 'def-edebug-elem-spec' to define Edebug spec elements.
-These used to be defined with 'def-edebug-spec' thus conflating the
-two name spaces, which lead to name collisions.
-The use of 'def-edebug-spec' to define Edebug spec elements is
-declared obsolete.
-
----
-** The sb-image.el library is now obsolete.
-This was a compatibility kludge which is no longer needed.
-
----
-** Some libraries obsolete since Emacs 23 have been removed:
-ledit.el, lmenu.el, lucid.el and old-whitespace.el.
-
----

-** Some functions and variables obsolete since Emacs 22 have been removed:
-'erc-current-network', 'gnus-article-hide-pgp-hook',
-'gnus-inews-mark-gcc-as-read', 'gnus-treat-display-xface',
-'gnus-treat-strip-pgp', 'nnmail-spool-file'.
-
----
-** The obsolete function 'thread-alive-p' has been removed.
-
----
-** The variable 'force-new-style-backquotes' has been removed.
-This removes the final remaining trace of old-style backquotes.
-
----
-** Some obsolete variable and function aliases in dbus.el have been removed.
-In Emacs 24.3, the variable 'dbus-event-error-hooks' was renamed to
-'dbus-event-error-functions' and the function
-'dbus-call-method-non-blocking' was renamed to 'dbus-call-method'.
-The old names, which were kept as obsolete aliases of the new names,
-have now been removed.
-
----
-** 'find-function-source-path' renamed and re-documented.
-The 'find-function' command (and various related commands) were
-documented to respect 'find-function-source-path', and to search for
-objects in files specified by that variable. It's unclear when this
-actually changed, but at some point (perhaps decades ago) these
-commands started using 'load-history' to determine where symbols had
-been defined (which is much faster). The doc strings of all the
-affected function has been updated. 'find-function-source-path' was
-still being used by 'find-library' and related commands, so the
-variable has been renamed to 'find-library-source-path', and
-'find-function-source-path' is now an obsolete variable alias.
-
----
-** The macro 'vc-call' no longer evaluates its second argument twice.
+* Changes in Emacs 29.1
-* Lisp Changes in Emacs 28.1
-
-+++
-** The 'interactive' syntax has been extended to allow listing applicable
modes.
-Forms like '(interactive "p" dired-mode)' can be used to annotate the
-commands as being applicable for modes derived from 'dired-mode',
-or if the mode is a minor mode, that the current buffer has that
-minor mode activated. Note that using this form will create byte code
-that is not compatible with byte code in previous Emacs versions.
-
-+++
-** New forms to declare how completion should happen has been added.
-'(declare (completion PREDICATE))' can be used as a general predicate
-to say whether the command should be present when completing with
-'M-x TAB'. '(declare (modes MODE...))' can be used as a short-hand
-way of saying that the command should be present when completing from
-buffers in major modes derived from MODE..., or, if it's a minor mode,
-whether that minor mode is enabled in the current buffer.
-
-+++
-** 'define-minor-mode' now takes an ':interactive' argument.
-This can be used for specifying which modes this minor mode is meant
-for, or to make the new minor mode non-interactive. The default value
-is t.
-
-+++
-** 'define-derived-mode' now takes an ':interactive' argument.
-This can be used to control whether the defined mode is a command
-or not, and is useful when defining commands that aren't meant to be
-used by users directly.
-
-+++
-** 'define-globalized-minor-mode' now takes a ':predicate' parameter.
-This can be used to control which major modes the minor mode should be
-used in.
-
-+++
-** 'condition-case' now allows for a success handler.
-It is written as '(:success BODY...)' where BODY is executed
-whenever the protected form terminates without error, with the
-specified variable bound to the value of the protected form.
-
-+++
-** New function 'benchmark-call' to measure the execution time of a function.
-Additionally, the number of repetitions can be expressed as a minimal duration
-in seconds.
-
-+++
-** The value thrown to the 'exit' label can now be a function.
-This is in addition to values t or nil. If the value is a function,
-the command loop will call it with zero arguments before returning.
-
-+++
-** The behavior of 'format-spec' is now closer to that of 'format'.
-In order for the two functions to behave more consistently,
-'format-spec' now pads and truncates based on string width rather than
-length, and also supports format specifications that include a
-truncating precision field, such as "%.2a".
-
----
-** 'defvar' detects the error of defining a variable currently lexically bound.
-Such mixes are always signs that the outer lexical binding was an
-error and should have used dynamic binding instead.
-
----
-** New variable 'inhibit-mouse-event-check'.
-If bound to non-nil, a command with '(interactive "e")' doesn't signal
-an error when invoked by input event that is not a mouse click (e.g.,
-a key sequence).
-
----
-** New variable 'redisplay-skip-initial-frame' to enable batch redisplay tests.
-Setting it to nil forces the redisplay to do its job even in the
-initial frame used in batch mode.
-
-+++
-** Doc strings can now link to customization groups.
-Text like "customization group `whitespace'" will be made into a
-button. When clicked, it will open a Custom buffer displaying that
-customization group.
-
-+++
-** Doc strings can now link to man pages.
-Text like "man page `chmod(1)'" will be made into a button. When
-clicked, it will open a Man mode buffer displaying that man page.
-
-+++
-** Buffers can now be created with certain hooks disabled.
-The functions 'get-buffer-create' and 'generate-new-buffer' accept a
-new optional argument INHIBIT-BUFFER-HOOKS. If non-nil, the new
-buffer does not run the hooks 'kill-buffer-hook',
-'kill-buffer-query-functions', and 'buffer-list-update-hook'. This
-avoids slowing down internal or temporary buffers that are never
-presented to users or passed on to other applications.
-
-+++
-** New command 'make-directory-autoloads'.
-This does the same as the old command 'update-directory-autoloads',
-but has different semantics: Instead of passing in the output file via
-the dynamically bound 'generated-autoload-file' variable, the output
-file is now a explicit parameter.
-
----
-** Dragging a file into Emacs pushes the file name onto 'file-name-history'.
-
----
-** The 'easymenu' library is now preloaded.
-
----
-** The 'iso-transl' library is now preloaded.
-This means that keystrokes like 'Alt-[' are defined by default,
-instead of only becoming available after doing (for instance)
-'C-x 8 <letter>'.
-
----
-** ':safe' settings in 'defcustom' are now propagated to the loaddefs files.
-
-+++
-** New ':type' for 'defcustom' for nonnegative integers.
-The new 'natnum' type can be used for options that should be
-nonnegative integers.
-
-+++
-** ERT can now output more verbose test failure reports.
-If the 'EMACS_TEST_VERBOSE' environment variable is set, failure
-summaries will include the failing condition.
-
-** Byte compiler changes
-
-+++
-*** New byte-compiler check for missing dynamic variable declarations.
-It is meant as an (experimental) aid for converting Emacs Lisp code
-to lexical binding, where dynamic (special) variables bound in one
-file can affect code in another. For details, see the manual section
-"(elisp) Converting to Lexical Binding".
-
-+++
-*** 'byte-recompile-directory' can now compile symlinked ".el" files.
-This is achieved by giving a non-nil FOLLOW-SYMLINKS parameter.
-
----
-*** The byte-compiler now warns about too wide documentation strings.
-By default, it will warn if a documentation string is wider than the
-largest of 'byte-compile-docstring-max-column' or 'fill-column'
-characters.
-
-+++
-*** 'byte-compile-file' optional argument LOAD is now obsolete.
-To load the file after byte-compiling, add a call to 'load' from Lisp
-or use 'M-x emacs-lisp-byte-compile-and-load' interactively.
-
-** Macroexp
-
----
-*** New function 'macroexp-file-name' to know the name of the current file.
-
----
-*** New function 'macroexp-compiling-p' to know if we're compiling.
-
----
-*** New function 'macroexp-warn-and-return' to help emit warnings.
-This used to be named 'macroexp--warn-and-return' and has proved useful
-and well-behaved enough to lose the "internal" marker.
-
-** map.el
-
----
-*** Alist keys are now consistently compared with 'equal' by default.
-Until now, 'map-elt' and 'map-delete' compared alist keys with 'eq' by
-default. They now use 'equal' instead, for consistency with
-'map-put!' and 'map-contains-key'.
-
-*** Pcase 'map' pattern added keyword symbols abbreviation.
-A pattern like '(map :sym)' binds the map's value for ':sym' to 'sym',
-equivalent to '(map (:sym sym))'.
-
----
-*** The function 'map-copy' now uses 'copy-alist' on alists.
-This is a slightly deeper copy than the previous 'copy-sequence'.
-
----
-*** The function 'map-contains-key' now supports plists.
-
----
-*** More consistent duplicate key handling in 'map-merge-with'.
-Until now, 'map-merge-with' promised to call its function argument
-whenever multiple maps contained 'eql' keys. However, this did not
-always coincide with the keys that were actually merged, which could
-be 'equal' instead. The function argument is now called whenever keys
-are merged, for greater consistency with 'map-merge' and 'map-elt'.
-
-** pcase
-
-+++
-*** The 'or' pattern now binds the union of the vars of its sub-patterns.
-If a variable is not bound by the subpattern that matched, it gets bound
-to nil. This was already sometimes the case, but it is now guaranteed.
-
-+++
-*** The 'pred' pattern can now take the form '(pred (not FUN))'.
-This is like '(pred (lambda (x) (not (FUN x))))' but results
-in better code.
-
----
-*** New function 'pcase-compile-patterns' to write other macros.
-
-+++
-*** Added 'cl-type' pattern.
-The new 'cl-type' pattern compares types using 'cl-typep', which allows
-comparing simple types like '(cl-type integer)', as well as forms like
-'(cl-type (integer 0 10))'.
-
-+++
-*** New macro 'pcase-setq'.
-This macro is the 'setq' equivalent of 'pcase-let', which allows for
-destructuring patterns in a 'setq' form.
-
-** Edebug
-
-*** Edebug specification lists can use some new keywords:
-
-+++
-**** '&interpose SPEC FUN ARGS..' lets FUN control parsing after SPEC.
-More specifically, FUN is called with 'HEAD PF ARGS..' where
-PF is a parsing function that expects a single argument (the specs to
-use) and HEAD is the code that matched SPEC.
-
-+++
-**** '&error MSG' unconditionally aborts the current edebug instrumentation.
-
-+++
-**** '&name SPEC FUN' extracts the current name from the code matching SPEC.
-
-** Dynamic modules changes
-
-+++
-*** Type aliases for module functions and finalizers.
-The module header 'emacs-module.h' now contains type aliases
-'emacs_function' and 'emacs_finalizer' for module functions and
-finalizers, respectively.
-
-+++
-*** Module functions can now be made interactive.
-Use 'make_interactive' to give a module function an interactive
-specification.
-
-+++
-*** Module functions can now install an optional finalizer.
-The finalizer is called when the function object is garbage-collected.
-Use 'set_function_finalizer' to set the finalizer and
-'get_function_finalizer' to retrieve it.
-
-+++
-*** Modules can now open a channel to an existing pipe process.
-Modules can use the new module function 'open_channel' to do that.
-On capable systems, modules can use this functionality to
-asynchronously send data back to Emacs.
-
-+++
-*** A new module API 'make_unibyte_string'.
-It can be used to create Lisp strings with arbitrary byte sequences
-(a.k.a. "raw bytes").

-** Shorthands for Lisp symbols.
-Shorthands are a general purpose namespacing system to make Emacs
-Lisp's symbol-naming etiquette easier to use. A shorthand is any
-symbolic form found in Lisp source that "abbreviates" a symbol's print
-name. Among other applications, this feature can be used to avoid
-name clashes and namespace pollution by renaming an entire file's
-worth of symbols with proper and longer prefixes, without actually
-touching the Lisp source. For details, see the manual section
-"(elisp) Shorthands".
-
-+++
-** New function 'string-search'.
-This function takes two string parameters and returns the position of
-the first instance of the former string in the latter.
-
-+++
-** New function 'string-replace'.
-This function works along the line of 'replace-regexp-in-string', but
-it matches on fixed strings instead of regexps, and does not change
-the global match state.
-
-+++
-** New function 'ensure-list'.
-This function makes a list of its object if it's not a list already.
-If it's already a list, the list is returned as is.

-for the specified file.
-
-+++
-** New function 'directory-empty-p'.
-This predicate tests whether a given file name is an accessible
-directory and whether it contains no other directories or files.
-
-+++
-** New function 'buffer-local-boundp'.
-This predicate says whether a symbol is bound in a specific buffer.
-
-+++
-** New function 'always'.
-This is identical to 'ignore', but returns t instead.
-
-+++
-** New function 'sxhash-equal-including-properties'.
-This is identical to 'sxhash-equal' but also accounts for string
-properties.
-
----
-** New function 'buffer-line-statistics'.
-This function returns some statistics about the line lengths in a buffer.
-
----
-** New function 'color-values-from-color-spec'.
-This can be used to parse RGB color specs in several formats and
-convert them to a list '(R G B)' of primary color values.
-
----
-** New function 'custom-add-choice'.
-This function can be used by modes to add elements to the
-'choice' customization type of a variable.

-** New function 'dom-print'.
-
-+++
-** New function 'dom-remove-attribute'.
-
----

-Parse a string as a mail address-like string.
-
----
-** New function 'make-separator-line'.
-Make a string appropriate for usage as a visual separator line.
-
-+++
-** New function 'object-intervals'.
-This function returns a copy of the list of intervals (i.e., text
-properties) in the object in question (which must either be a string
-or a buffer).
-
-+++
-** New function 'process-lines-ignore-status'.
-This is like 'process-lines', but does not signal an error if the
-return status is non-zero. 'process-lines-handling-status' has also
-been added, and takes a callback to handle the return status.
-
-+++
-** New function 'require-theme'.
-This function is like 'require', but searches 'custom-theme-load-path'
-instead of 'load-path'. It can be used by Custom themes to load
-supporting Lisp files when 'require' is unsuitable.
-
-+++
-** New function 'seq-union'.
-This function takes two sequences and returns a list of all elements
-that appear in either of them, with no two elements that compare equal
-appearing in the result.
-
-+++
-** New function 'syntax-class-to-char'.
-This does almost the opposite of 'string-to-syntax' -- it returns the
-syntax descriptor (a character) given a raw syntax descriptor (an
-integer).
-
-+++
-** New functions 'null-device' and 'path-separator'.
-These functions return the connection local value of the respective
-variables. This can be used for remote hosts.
-
-+++
-** New predicate functions 'length<', 'length>' and 'length='.
-Using these functions may be more efficient than using 'length' (if
-the length of a (long) list is being computed just to compare this
-length to a number).
-
-+++
-** New macro 'dlet' to dynamically bind variables.
-
-+++
-** New macro 'with-existing-directory'.
-This macro binds 'default-directory' to some other existing directory
-if 'default-directory' doesn't exist, and then executes the body forms.
-
-+++
-** New variable 'current-minibuffer-command'.
-This is like 'this-command', but it is bound recursively when entering
-the minibuffer.
-
-+++
-** New variable 'inhibit-interaction' to make user prompts signal an error.
-If this is bound to something non-nil, functions like
-'read-from-minibuffer', 'read-char' (and related) will signal an
-'inhibited-interaction' error.
-
----
-** New variable 'indent-line-ignored-functions'.
-This allows modes to cycle through a set of indentation functions
-appropriate for those modes.
-
-+++
-** New variable 'print-integers-as-characters' modifies integer printing.
-If this variable is non-nil, character syntax is used for printing
-numbers when this makes sense, such as '?A' for 65.
-
-+++
-** New variable 'tty-menu-calls-mouse-position-function'.
-This controls whether 'mouse-position-function' is called by functions
-that retrieve the mouse position when that happens during TTY menu
-handling. Lisp programs that set 'mouse-position-function' should
-also set this variable non-nil if they are compatible with the tty
-menu handling.
-
-+++
-** New variables that hold default buffer names for shell output.
-The new constants 'shell-command-buffer-name' and
-'shell-command-buffer-name-async' store the default buffer names
-for the output of, respectively, synchronous and async shell
-commands.
-
----
-** New variables 'read-char-choice-use-read-key' and 'y-or-n-p-use-read-key'.
-When non-nil, then functions 'read-char-choice' and 'y-or-n-p'
-(respectively) use the function 'read-key' to read a character instead
-of using the minibuffer.
-
-+++
-** New variable 'global-minor-modes'.
-This variable holds a list of currently enabled global minor modes (as
-a list of symbols).
-
-+++
-** New buffer-local variable 'local-minor-modes'.
-This permanently buffer-local variable holds a list of currently
-enabled non-global minor modes in the current buffer (as a list of
-symbols).
-
-+++
-** New completion function 'affixation-function' to add prefix/suffix.
-It accepts a list of completions and should return a list where
-each element is a list with three elements: a completion,
-a prefix string, and a suffix string.
-
-+++
-** New completion function 'group-function' for grouping candidates.
-It takes two arguments: a completion candidate and a 'transform' flag.
-
-+++
-** New error symbol 'minibuffer-quit'.
-Signaling it has almost the same effect as 'quit' except that it
-doesn't cause keyboard macro termination.
-
-+++
-** New error 'remote-file-error', a subcategory of 'file-error'.
-It is signaled if a remote file operation fails due to internal
-reasons, and could block Emacs. It does not replace 'file-error'
-signals for the usual cases. Timers, process filters and process
-functions, which run remote file operations, shall protect themselves
-against this error.
-
-If such an error occurs, please report this as bug via 'M-x report-emacs-bug'.
-Until it is solved you could ignore such errors by performing
-
- (setq debug-ignored-errors (cons 'remote-file-error debug-ignored-errors))
-
-+++
-** New macro 'named-let' added to subr-x.el.
-It provides Scheme's "named let" looping construct.
-
----
-** Emacs now attempts to test for high-rate subprocess output more fairly.
-When several subprocesses produce output simultaneously at high rate,
-Emacs will now by default attempt to service them all in a round-robin
-fashion. Set the new variable 'process-prioritize-lower-fds' to a
-non-nil value to get back the old behavior, whereby after reading
-from a subprocess, Emacs would check for output of other subprocesses
-in a way that is likely to read from the same process again.
-
-+++
-** 'set-process-buffer' now updates the process mark.
-The mark will be set to point to the end of the new buffer.
-
-+++
-** 'unlock-buffer' displays warnings instead of signaling.
-Instead of signaling 'file-error' conditions for file system level
-errors, the function now calls 'display-warning' and continues as if
-the error did not occur.
-
-+++
-** 'read-char-from-minibuffer' and 'y-or-n-p' support 'help-form'.
-If you bind 'help-form' to a non-nil value while calling these functions,
-then pressing 'C-h' ('help-char') causes the function to evaluate 'help-form'
-and display the result.
-
-+++
-** 'read-number' now has its own history variable.
-Additionally, the function now accepts a HIST argument which can be
-used to specify a custom history variable.
-
-+++
-** 'set-window-configuration' now takes two optional parameters,
-'dont-set-frame' and 'dont-set-miniwindow'. The first of these, when
-non-nil, instructs the function not to select the frame recorded in
-the configuration. The second prevents the current minibuffer being
-replaced by the one stored in the configuration.
-
----
-** 'count-windows' now takes an optional parameter ALL-FRAMES.
-The semantics are as with 'walk-windows'.
-
-+++
-** 'truncate-string-ellipsis' now uses '…' by default.
-Modes that use 'truncate-string-to-width' with non-nil, non-string
-argument ELLIPSIS, will now indicate truncation using '…' when
-the selected frame can display it, and using "..." otherwise.
-
-+++
-** 'string-width' now accepts two optional arguments FROM and TO.
-This allows calculating the width of a substring without consing a
-new string.
-
-+++
-** 'directory-files' now takes an additional COUNT parameter.
-The parameter makes 'directory-files' return COUNT first file names
-from a directory. If MATCH is also given, the function will return
-first COUNT file names that match the expression. The same COUNT
-parameter has been added to 'directory-files-and-attributes'.
-
-+++
-** 'count-lines' can now ignore invisible lines.
-This is controlled by the optional parameter IGNORE-INVISIBLE-LINES.
-
----
-** 'count-words' now crosses field boundaries.
-Originally, 'count-words' would stop counting at the first field
-boundary it encountered; now it keeps counting all the way to the
-region's (or buffer's) end.
-
-+++
-** File-related APIs can optionally follow symlinks.
-The functions 'file-modes', 'set-file-modes', and 'set-file-times' now
-have an optional argument specifying whether to follow symbolic links.
-
-+++
-** 'format-seconds' can now be used for sub-second times.
-The new optional "," parameter has been added, and
-'(format-seconds "%mm %,1ss" 66.4)' will now result in "1m 6.4s".
-
-+++
-** 'parse-time-string' can now parse ISO 8601 format strings.
-These have a format like "2020-01-15T16:12:21-08:00".
-
----
-** 'make-network-process', 'make-serial-process' ':coding' behavior change.
-Previously, passing ':coding nil' to either of these functions would
-override any non-nil binding for 'coding-system-for-read' and
-'coding-system-for-write'. For consistency with 'make-process' and
-'make-pipe-process', passing ':coding nil' is now ignored. No code in
-Emacs depended on the previous behavior; if you really want the
-process' coding-system to be nil, use 'set-process-coding-system'
-after the process has been created, or pass in ':coding '(nil nil)'.
-
-+++
-** 'open-network-stream' now accepts a ':coding' argument.
-This allows specifying the coding systems used by a network process
-for encoding and decoding without having to bind
-'coding-system-for-{read,write}' or call 'set-process-coding-system'.
-
-+++
-** 'open-network-stream' can now take a ':capability-command' that's a
function.
-The function is called with the greeting from the server as its only
-parameter, and allows sending different TLS capability commands to the
-server based on that greeting.
-
-+++
-** 'open-gnutls-stream' now also accepts a ':coding' argument.
-
----
-** 'process-attributes' now works under OpenBSD, too.
-
-+++
-** 'format-spec' now takes an optional SPLIT parameter.
-If non-nil, 'format-spec' will split the resulting string into a list
-of strings, based on where the format specs (and expansions) were.
-
----
-** 'unload-feature' now also tries to undo additions to buffer-local hooks.
-
----
-** 'while-no-input-ignore-events' accepts more special events.
-The special events 'dbus-event' and 'file-notify' are now ignored in
-'while-no-input' when added to this variable.
-
----
-** 'start-process-shell-command' and 'start-file-process-shell-command'
-do not support the old calling conventions any longer.
-
-+++
-** 'yes-or-no-p' and 'y-or-n-p' PROMPT parameter no longer needs trailing
space.
-In other words, the prompt can now end with "?" instead of "? ". This
-has been the case since Emacs 24.4 but was not announced or documented
-until now. (Checkdoc has also been updated to accept this convention.)
-
-+++
-** The 'uniquify' argument in 'auto-save-file-name-transforms' can be a symbol.
-If this symbol is one of the members of 'secure-hash-algorithms',
-Emacs constructs the nondirectory part of the auto-save file name by
-applying that 'secure-hash' to the buffer file name. This avoids any
-risk of excessively long file names.
-
-+++
-** New user option 'process-file-return-signal-string'.
-It controls, whether 'process-file' returns a string when a remote
-process is interrupted by a signal.
-
-** EIEIO Changes
-
-+++
-*** The macro 'oref-default' can now be used with 'setf'.
-It is now defined as a generalized variable that can be used with
-'setf' to modify the value stored in a given class slot.
-
----
-*** 'form' in '(eql form)' specializers in 'cl-defmethod' is now evaluated.
-This corresponds to the behavior of defmethod in Common Lisp Object System.
-For compatibility, '(eql SYMBOL)' does not evaluate SYMBOL, for now.
-
-** D-Bus
-
-+++
-*** Property values can be typed explicitly.
-'dbus-register-property' and 'dbus-set-property' accept now optional
-type symbols. Both functions propagate D-Bus errors.
-
-+++
-*** Registered properties can have the new access type ':write'.
-
-+++
-*** In case of problems, handlers can emit proper D-Bus error messages now.
-
-+++
-*** D-Bus errors, which have been converted from incoming D-Bus error
-messages, contain the error name of that message now.
-
-+++
-*** D-Bus messages can be monitored with the new command 'dbus-monitor'.
-
-+++
-*** D-Bus events have changed their internal structure.
-They carry now the destination and the error-name of an event. They
-also keep the type information of their arguments. Use the
-'dbus-event-*' accessor functions.
-
-** Buttons
-
-+++
-*** New minor mode 'button-mode'.
-This minor mode does nothing else than install 'button-buffer-map' as
-a minor mode map (which binds the 'TAB' / 'S-TAB' key bindings to navigate
-to buttons), and can be used in any view-mode-like buffer that has
-buttons in it.
-
-+++
-*** New utility function 'button-buttonize'.
-This function takes a string and returns a string propertized in a way
-that makes it a valid button.
-
----
-** 'text-scale-mode' can now adjust font size of the header line.
-When the new buffer local variable 'text-scale-remap-header-line'
-is non-nil, 'text-scale-adjust' will also scale the text in the header
-line when displaying that buffer.
-
-This is useful for major modes that arrange their display in a tabular
-form below the header line. It is enabled by default in
-'tabulated-list-mode' and its derived modes.
-
----
-** 'ascii' is now a coding system alias for 'us-ascii'.
-
----
-** New coding-systems for EBCDIC variants.
-New coding-systems 'ibm256', 'ibm273', 'ibm274', 'ibm277', 'ibm278',
-'ibm280', 'ibm281', 'ibm284', 'ibm285', 'ibm290', 'ibm297'. These are
-variants of the EBCDIC encoding tailored to some European and Japanese
-locales. They are also available as aliases 'ebcdic-cp-*' (e.g.,
-'ebcdic-cp-fi' for the Finnish variant 'ibm278'), and 'cp2xx' (e.g.,
-'cp278' for 'ibm278'). There are also new charsets 'ibm2xx' to
-support these coding-systems.
-
-+++
-** New 'Bindat type expression' description language.
-This new system is provided by the new macro 'bindat-type' and
-obsoletes the old data layout specifications. It supports
-arbitrary-size integers, recursive types, and more. See the Info node
-"(elisp) Byte Packing" in the ELisp manual for more details.
-
-+++
-** New macro 'with-environment-variables'.
-This macro allows setting environment variables temporarily when
-executing a form.
+* Editing Changes in Emacs 29.1
-* Changes in Emacs 28.1 on Non-Free Operating Systems
-
-+++
-** On MS-Windows, Emacs can now use the native image API to display images.
-Emacs can now use the MS-Windows GDI+ library to load and display
-images in JPEG, PNG, GIF and TIFF formats. This support is available
-unless Emacs was configured '--without-native-image-api'.
-
-This feature is experimental, and needs to be turned on to be used.
-To turn this on, set the variable 'w32-use-native-image-API' to a
-non-nil value. Please report any bugs you find while using the native
-image API via 'M-x report-emacs-bug'.
-
-+++
-** On MS-Windows, Emacs can now toggle the IME.
-A new function 'w32-set-ime-open-status' can now be used to disable
-and enable the MS-Windows native Input Method Editor (IME) at run
-time. A companion function 'w32-get-ime-open-status' returns the
-current IME activation status.
-
---
-** On macOS, 's-<left>' and 's-<right>' are now bound to
-'move-beginning-of-line' and 'move-end-of-line' respectively. The commands
-to select previous/next frame are still bound to 's-~' and 's-`'.
+* Changes in Specialized Modes and Packages in Emacs 29.1
-+++
-** On macOS, Emacs can now load dynamic modules with a ".dylib" suffix.
-'module-file-suffix' now has the value ".dylib" on macOS, but the
-".so" suffix is supported as well.
-
----
-** On macOS, the user option 'make-pointer-invisible' is now honored.
-
----
-** On macOS, Xwidget is now supported.
-If Emacs was built with xwidget support, you can access the embedded
-webkit browser with 'M-x xwidget-webkit-browse-url'. Viewing two
-instances of xwidget webkit is not supported.
-
----
-*** Downloading files from xwidget-webkit is now supported.
-The new user option 'xwidget-webkit-download-dir' says where to download to.
-
----
-*** New command 'xwidget-webkit-clone-and-split-below'.
-Open a new window below displaying the current URL.
+
+* New Modes and Packages in Emacs 29.1
----
-*** New command 'xwidget-webkit-clone-and-split-right'.
-Open a new window to the right displaying the current URL.
+
+* Incompatible Lisp Changes in Emacs 29.1
----
-*** New user option 'xwidget-webkit-enable-plugins'.
-If non-nil, enable plugins in xwidget. (This is only available on
-macOS.)
+
+* Lisp Changes in Emacs 29.1
-+++
-** New macOS Contacts back-end for EUDC.
-This backend works on newer versions of macOS and is generally
-preferred over the eudcb-mab.el backend.
