MH-E 7.90 released

[Bill Wohler]

MH-E is the Emacs interface to the MH mail system. It offers all the
functionality of MH, the visual orientation and simplicity of use of a
GUI, and full integration with Emacs and XEmacs, including thorough
configuration and online help.

* Changes in MH-E 7.90

Version 7.90 is the first 8.0 beta release and is a release that has
finally broken away from some unfortunate legacy decisions in favor of
something that will be easier to use and support. Many bugs were fixed
and many features were added, including making the pick search
equivalent to the other types of searches.

The rewrite of the manual accelerated dramatically in recent months
and drove the changes in this release. In order to make the
manual--and hence the software--better, clearer, more consistent, more
predictable, and easier to understand, many variables and functions
were renamed. The changes to the user-visible variables are listed
here. It is our hope that you, dear MH-E user, will embrace the
changes for the better and forgive us from making so many incompatible
changes.

If you use undocumented functionality, be sure to read the ChangeLog
for changes that might affect you.

** New Features in MH-E 7.90

*** Entry Points Have Moved

Emacs 21 users must now add `(require 'mh-autoloads)' because the
entry points (such as `mh-rmail' and `mh-smail') have moved to
different files which have made the autoloads that come with Emacs
inaccurate. This change was necessary because the code was reorganized
to remove circular dependencies, to make the code more stable and
maintainable, and to reduce the time to load MH-E.

*** MH-E No Longer Calls install-mh

The new variant detection code makes use of `mhparam' which assumes
that your MH environment has already been set up. The code to call
`install-mh', which could no longer be run anyway, was removed.

*** Use run-hook-with-args

We use normal hooks whenever possible and do not use
`run-hook-with-args' (with one documented exception) (closes SF
#643702).

*** Merge mh-index.el and mh-pick.el

We merged `mh-index.el' and `mh-pick.el' into a new file
`mh-search.el'. As part of this process, the old `F s' behavior of
adding messages to the search sequence has been removed. The `F i'
keybinding was then renamed to `F s' (`mh-search'). The mode of the
search-pattern buffer was renamed from MH-Pick to MH-Search. Within
the MH-Search buffer, the command `C-c C-p' (`mh-pick-do-search') now
runs pick on the given folder recursively and displays the results in
a search folder like the other search methods (closes SF #829207).

*** Improve Security of mh-fetch-x-image-url

The default has been changed to "Never Fetch." Those of you who like
the value of "Ask Before Fetching" will have to customize this option
(closes SF #831278).

*** Remove Emacs 20 Support

As it turns out, we had already added some code that didn't work on
Emacs 20. However, now we've formalized it and removed code that was
present solely for Emacs 20 support (closes SF #1359240).

*** Derive mh-letter-mode from mail-mode

MH-Letter mode is now derived from `mail-mode'. We were able to delete
a lot of code. In return, there are a few `mail-mode' commands that
are available that may or may not be useful and the `mail-mode-hook'
is run (closes SF #1385571).

*** Add Choices to mh-to-field-choices

In MH-Letter mode, you can use the "C-c C-f (mh-to-field)" prefix to
go to and insert fields. The fields "Reply-To:", "Mail-Reply-To:",
"Mail-Followup-To:" can now be created via the "C-r", "C-a" (for
author), and "C-l" keys respectively. The key for the "From:" field
has been renamed from "C-r" to "C-m" for consistency with `mail-mode'
(closes SF #1400139).

*** MH-Folder Keymap Changes

The function `mh-ps-print-toggle-mime' was never implemented and the
functionality in `mh-ps-print-msg-show' was better afforded by
`mh-ps-print-msg' and `mh-ps-print-msg-file'.

Key          7.4.85                        7.4.90

F i          mh-index-search               -
F s          mh-search-folder              mh-search
P A          mh-ps-print-toggle-mime       -
P M          mh-ps-print-toggle-mime       -
P s          mh-ps-print-msg-show          -

*** MH-Letter Keymap Changes

The change where `mh-letter-mode' derives from `mail-mode' adds a few
keybindings. Some are interesting; experiment! Most of the changes
have to do with the renaming of the functions with "mhn" in them to
"mh" because nmh doesn't use `mhn'. The names were also made
consistent with the the family of "mml" functions.

Key          7.4.85                        7.4.90

C-c C-e      mh-edit-mhn                   mh-mh-to-mime
C-c C-f C-a  -                             mh-to-field
C-c C-f C-l  -                             mh-to-field
C-c C-f RET  -                             mh-to-field
C-c C-f a    -                             mh-to-field
C-c C-f l    -                             mh-to-field
C-c C-f m    -                             mh-to-field
C-c RET C-g  mh-mhn-compose-anon-ftp       mh-mh-compose-anon-ftp
C-c RET C-t  mh-mhn-compose-external-compressed-tar
                                           mh-mh-compose-external-compressed-tar
C-c RET C-u  mh-revert-mhn-edit            mh-mh-to-mime-undo
C-c RET C-x  mh-mhn-compose-external-type  mh-mh-compose-external-type
C-c RET g    mh-mhn-compose-anon-ftp       mh-mh-compose-anon-ftp
C-c RET t    mh-mhn-compose-external-compressed-tar
                                           mh-mh-compose-external-compressed-tar
C-c RET u    mh-revert-mhn-edit            mh-mh-to-mime-undo
C-c RET x    mh-mhn-compose-external-type  mh-mh-compose-external-type

*** MH-Search Keymap Changes

These are the changes associated with the new search mode. The command
`C-c C-c' (`mh-index-do-search') now performs the standard indexed
search, while `C-c C-p' (`mh-pick-do-search') runs pick as before,
only better!

Key          7.4.85                        7.4.90

C-c C-c      mh-do-search                  mh-index-do-search
C-c TAB      mh-index-do-search            -

** New Variables in MH-E 7.90

*** mh-after-commands-processed-hook

Hook run by `x' (`mh-execute-commands') after performing outstanding
refile and delete requests.

*** mh-before-commands-processed-hook

Renamed from `mh-folder-updated-hook'. It wasn't clear whether
`mh-folder-updated-hook' was run before or after the commands were
executed. We now provide both with clear names.

*** mh-highlight-citation-style

Renamed from `mh-highlight-citation-p' since it wasn't a boolean. The
new name is also more descriptive.

*** mh-insert-signature-hook

Renamed from `mh-letter-insert-signature-hook' since most of the other
hooks do not carry the mode in the prefix and because the new name is
equally clear.

*** mh-kill-folder-suppress-prompt-hooks

Renamed from `mh-kill-folder-suppress-prompt-hook'. By convention,
abnormal hooks, which this is, either have a -function or -hooks
suffix.

*** mh-mhl-format-file

Renamed from `mhl-formfile' to put it in the MH-E namespace and to be
consistent with other similar options.

*** mh-mh-to-mime-hook

Renamed from `mh-edit-mhn-hook'. We have a family of `mh-mml-to-mime'
functions and variables; the older mhn functions and variables were
renamed to have a consistent `mh-mh-to-mime' prefix.

*** mh-new-messages-folders

Renamed from `mh-index-new-messages-folders' for clarity.

*** mh-path

Additional list of directories to search for MH.

*** mh-redist-full-contents-flag

On means the `dist' command needs entire letter for redistribution.
This was previously a variable. It's now an option.

*** mh-search-mode-hook

Renamed from `mh-pick-mode-hook' as part of the
`mh-index.el'/`mh-pick.el' merge into `mh-search.el'.

*** mh-search-program

Renamed from `mh-index-program' as part of the
`mh-index.el'/`mh-pick.el' merge into `mh-search.el'.

*** mh-sortm-args

Additional arguments for `sortm'. This was previously an internal
variable. It's now an user-customizable option.

*** mh-speed-update-interval

Renamed from `mh-speed-flists-interval' for clarity.

*** mh-ticked-messages-folders

Renamed from `mh-index-ticked-messages-folders' for clarity.

*** mh-xemacs-tool-bar-position

Renamed from `mh-xemacs-toolbar-position' per GNU Emacs naming conventions.

*** mh-xemacs-use-tool-bar-flag

Renamed from `mh-xemacs-use-toolbar-flag' per GNU Emacs naming conventions.

*** mh-yank-behavior

Renamed from `mh-yank-from-start-of-msg' for clarity.

** Variables Deleted in MH-E 7.90

*** mail-citation-hook

This is already defined in `sendmail.el'.

*** mh-edit-mhn-hook

Renamed to `mh-mh-to-mime-hook'.

*** mh-folder-updated-hook

Renamed to `mh-before-commands-processed-hook'.

*** mh-highlight-citation-p

Renamed to `mh-highlight-citation-style'.

*** mh-index-new-messages-folders

Renamed to `mh-new-messages-folders'.

*** mh-index-program

Renamed to `mh-search-program'.

*** mh-index-ticked-messages-folders

Renamed to `mh-ticked-messages-folders'.

*** mh-kill-folder-suppress-prompt-hook

Renamed to `mh-kill-folder-suppress-prompt-hooks'.

*** mh-letter-insert-signature-hook

Renamed to `mh-insert-signature-hook'.

*** mhl-formfile

Renamed to `mh-mhl-format-file'.

*** mh-pick-mode-hook

Renamed to `mh-search-mode-hook'.

*** mh-speed-flists-interval

Renamed to `mh-speed-update-interval'.

*** mh-speed-run-flists-flag

Deleted since setting `mh-speed-flists-interval' to 0 accomplishes the
same thing.

*** mh-xemacs-toolbar-position

Renamed to `mh-xemacs-tool-bar-position'.

*** mh-xemacs-use-toolbar-flag

Renamed to `mh-xemacs-use-tool-bar-flag'.

*** mh-yank-from-start-of-msg

Renamed to `mh-yank-behavior'.

** Bug Fixes in MH-E 7.90

*** Error Message When Trying to Send Using MH-E

This behavior is no longer observed (closes SF #1002103).

*** "Args out of range" Error in Displaying Message

This behavior is no longer observed (closes SF #1227504).

*** Front-and-back Truncation in mailto: Rendering

This behavior is no longer observed (closes SF #1227510).

*** Completions Offered by mh-refile-message Are Not Sorted

This behavior is no longer observed (closes SF #698734).

*** Add Message-ID to Outgoing Messages

If you replied to a message in your `+outbox', an `In-Reply-To:'
header field was created that broke threading at the recipient's end.
We now add a `Message-ID:' to outgoing messages which fixes this
(closes SF #725425).

*** Speedbar Creating New Folders Instead of Visiting Existing 

This was actually fixed in 7.4.3 (closes SF #792300).

*** Args Out of Range

This compilation error was actually fixed in 7.4.3 (closes SF
#806577).

*** Initialization Fails If ~/Mail Exists

MH-E no longer calls `install-mh' so this issue has gone away (closes
SF #835192).

*** RETURN Causes Infinite Loop in mh-letter

This behavior is no longer observed (closes SF #887346).

*** Missing Headers When Replying to All

User needed to edit `replgroupcomps' (closes SF #918194).

*** mh-find-path Doesn't Use mhparam

MH-E no longer peeks into the MH profile `~/.mh_profile' directly. It
uses `mhparam' instead (closes SF #1016027).

*** mh-index-previous-folder Does Not Work Correctly

If your cursor was on an item below a folder heading and you used
`M-TAB' (`mh-index-previous-folder'), you would move to the previous
folder heading. This has been fixed (closes SF #1126188).

*** XEmacs Compile Fails

Compiling produced a "Symbol's value as variable is void: require"
error on all files. This has been fixed. As a bonus, warnings have
been reduced from hundreds to just a few (closes SF #1127595).

*** buffer-offer-save Permanent Local

There was a movement to make `buffer-offer-save' a permanent local
which would have meant that we could not set it in `mh-letter-mode'.
However, this movement was fraught with issues and was postponed
(closes SF #1184756).

*** Better Handling of Empty cur Sequence

If you refiled a message into a folder and then used `F r'
(`mh-rescan-folder') in that folder, your cursor would be taken to the
first message. The cursor now stays where it was (closes SF #1207247).

*** Name of the Draft File in mh-comp.el

MH is documented to use the draft file. If you use a draft file for
something else (like Sylpheed), then use draft folders (closes SF
#1231483).

*** Use Standard Default Notation in Prompts

Emacs changed their defaults in prompts from "Prompt: [value]" to
"Prompt (default value): ". All MH-E prompts have been updated to
comply with the new standard (closes SF #1275933).

*** Msg Display Broken After Displaying Msg with Inline Image

Messages with inline images no longer trim certain message header
fields (closes SF #1306141).

*** mh-visit-folder Munges font-lock-keywords

MH-E broke highlighting in Gnus buffers. This was actually a problem
in CVS Emacs 22 and has been fixed there (closes SF #1393879).

*** Illegal Filename Chars for W32 Filesystems

Windows users who view `X-Image-URL:' images could not cache the
images since the cached image file names had illegal characters. This
has been fixed (closes SF #1396499).

*** mh-send Doesn't Handle mml Insertions Via mail-user-agent

Can now forward messages in Gnus if MH-E is your `mail-user-agent'
(closes SF #1399307).
