GNU Emacs NEWS -- history of user-visible changes. Copyright (C) 2010 Free Software Foundation, Inc. See the end of the file for license conditions. 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 ** 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 ** s-region.el is now declared obsolete, superceded by shift-select-mode enabled by default in 23.1.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. * Changes in Emacs 24.1 on non-free operating systems ---------------------------------------------------------------------- This file is part of GNU Emacs.
