User-agent: Wanderlust/2.14.0 (Africa) SEMI/1.14.6 (Maruoka) FLIM/1.14.8 (Shijō) APEL/10.6 Emacs/22.3 (sparc-sun-solaris2.8) MULE/5.0 (SAKAKI)

The Mac port based on Emacs 24.4 is now available from


                             YAMAMOTO Mitsuharu

** Fixed bugs

*** Keyboard input via Screen Sharing causes crash.
Reported by Kazu Yamamoto.

** Changes from emacs-24.3-mac-4.8

*** High-resolution icons are now distributed as a separate
package, which is available from

*** File notification is supported via GLib (you'll also need
`pkg-config' when running the configure command).

*** The `image-io' image type supports `:max-width',
`:max-height', and `:format' keywords just as in `imagemagick'.

*** Now that Image mode supports multi-frame image
navigation (`f', 'b', and `F'), you can browse multi-page
documents in several formats that `image-io' supports (e.g., PDF
and DOC) with the setting like this:
  (when (and (image-type-available-p 'image-io)
             (not (boundp 'imagemagick-render-type)))
     ;; Image I/O is used as a fallback of ImageMagick.
     (setq imagemagick-enabled-types t)
     (setq imagemagick-types-inhibit
          (cons 'XML (delq 'PDF imagemagick-types-inhibit)))
Note: if you have ImageMagick installed, you need to build the Mac
port executable without the genuine ImageMagick support so `image-io'
can be used as a fallback of `imagemagick'.

*** New variables mac-right-control-modifier,
mac-right-command-modifier, and mac-right-option-modifier.
Note: the left and right versions cannot be distinguished on some
environments such as Screen Sharing.  Also, certain combinations of a
key with both versions of the same modifier do not emit events at the
system level.

*** A single physical modifier key can be mapped to different Emacs
modifiers depending on its input type (ordinary keys, function keys,
or mouse operations) using the property list format `(:ordinary SYMBOL
:function SYMBOL :mouse SYMBOL)'.  By default, the option key works as
the normal Mac option key for the ordinary keys, and as the Alt
modifier for the function keys and the mouse operations.

*** Remove mac-ts-script-language-on-focus, which hasn't had any
effect on 64-bit executables.

*** Blend and blur fringe background of the focused frame with the
contents behind it on OS X 10.10.
This is currently experimental, hard-coded, and subject to change.

*** Add mouse pointer color support.

*** Animation-related properties of animated GIF are added to metadata
of images in the `image-io' image type.  Likewise for animated PNG on
OS X 10.10.
