Please send Emacs bug reports to bug-gnu-emacs@gnu.org.
|

If possible, use M-x report-emacs-bug.
|
||
|
||
This file is about changes in Emacs version 24.
|
||
|
||
See files NEWS.23, NEWS.22, NEWS.21, NEWS.20, NEWS.19, NEWS.18,
|
||
and NEWS.1-17 for changes in older Emacs versions.
|
||
|
||
You can narrow news to a specific version by calling `view-emacs-news'
|
||
with a prefix argument or by typing C-u C-h C-n.
|
||
|
||
|
||
Temporary note:
|
||
+++ indicates that the appropriate manual has already been updated.
|
||
--- means no change in the manuals is called for.
|
||
When you add a new item, please add it without either +++ or ---
|
||
so we will look at it and add it to the manual.

|
||
* Installation Changes in Emacs 24.1
|
||
|
||
---
|
||
** There are new configure options:
|
||
--with-mmdf, --with-mail-unlink, --with-mailhost.
|
||
These provide no new functionality, they just remove the need to edit
|
||
lib-src/Makefile by hand in order to use the associated features.
|
||
|
||
|
||
* Startup Changes in Emacs 24.1
|

|
||
|
||
* Changes in Emacs 24.1
|
||
|
||
+++
|
||
** Emacs now supports display and editing of bidirectional text.
|
||
Warning: This is still very much experimental! The existing support
|
||
is minimal, and when it's turned on (see below), many features are
|
||
likely to give unexpected results, or break, or even crash! Use at
|
||
your own risk!
|
||
|
||
See the node "Bidirectional Editing" in the Emacs Manual for some
|
||
initial documentation.
|
||
|
||
To turn this on in any given buffer, set the buffer-local variable
|
||
`bidi-display-reordering' to a non-nil value. The default is nil.
|
||
|
||
The buffer-local variable `bidi-paragraph-direction', if non-nil,
|
||
forces each paragraph in the buffer to have its base direction
|
||
according to the value of this variable. Possible values are
|
||
`right-to-left' and `left-to-right'. If the value is nil (the
|
||
default), Emacs determines the base direction of each paragraph from
|
||
its text, as specified by the Unicode Bidirectional Algorithm.
|
||
|
||
Reordering of bidirectional text for display in Emacs is a "Full
|
||
bidirectionality" class implementation of the Unicode Bidirectional
|
||
Algorithm.
|
||
|
||
** GTK scroll-bars are now placed on the right by default.
|
||
Use `set-scroll-bar-mode' to change this.
|
||
|
||
|
||
* Editing Changes in Emacs 24.1
|
||
|
||
|
||
* Changes in Specialized Modes and Packages in Emacs 24.1
|
||
|
||
** mpc.el: Can use pseudo tags of the form tag1|tag2 as a union of two tags.
|
||
** Customize
|
||
|
||
*** Customize buffers now contain a search field.
|
||
The search is performed using `customize-apropos'.
|
||
To turn off the search field, set custom-search-field to nil .
|
||
|
||
*** Custom options now start out hidden if at their default values.
|
||
Use the arrow to the left of the option name to toggle visibility.
|
||
|
||
*** custom-buffer-sort-alphabetically now defaults to t.
|
||
|
||
*** The color widget now has a "Choose" button, which allows you to
|
||
choose a color via list-colors-display.
|
||
|
||
** VC and related modes
|
||
|
||
*** vc-dir for Bzr supports viewing shelve contents and shelving snapshots.
|
||
|
||
*** Special markup can be added to log-edit buffers.
|
||
|
||
**** For Bzr, adding an
|
||
Author: NAME
|
||
line will add "--author NAME" to the "bzr commit" command.
|
||
|
||
**** For Hg, adding an
|
||
Author: NAME
|
||
line will add "--user NAME" to the "hg commit" command.
|
||
|
||
** Directory local variables can apply to file-less buffers.
|
||
For example, adding "(diff-mode . ((mode . whitespace)))" to your
|
||
.dir-locals.el file, will turn on `whitespace-mode' for *vc-diff*
|
||
buffers.
|
||
|
||
** s-region.el is now declared obsolete, superceded by shift-select-mode
|
||
enabled by default in 23.1.
|
||
|
||
** gdb-mi
|
||
|
||
*** GDB User Interface migrated to GDB Machine Interface and now
|
||
supports multithread non-stop debugging and debugging of several
|
||
threads simultaneously.
|
||
|
||
|
||
* New Modes and Packages in Emacs 24.1
|
||
|
||
** secrets.el is an implementation of the Secret Service API, an
|
||
interface to password managers like GNOME Keyring or KDE Wallet. The
|
||
Secret Service API requires D-Bus for communication.
|
||
|
||
|
||
* Incompatible Lisp Changes in Emacs 24.1
|
||
|
||
|
||
* Lisp changes in Emacs 24.1
|
||
|
||
** New completion style `substring'.
|
||
|
||
** Image API
|
||
|
||
*** When the image type is one of listed in `image-animated-types'
|
||
and the number of sub-images in the image is more then one, then the
|
||
new function `create-animated-image' creates an animated image where
|
||
sub-images are displayed successively with the duration defined by
|
||
`image-animate-max-time' and the delay between sub-images defined
|
||
by the Graphic Control Extension of the image.
