9 This file is about changes in Emacs version 24.
11 See files NEWS.23, NEWS.22, NEWS.21, NEWS.20, NEWS.19, NEWS.18,
12 and NEWS.1-17 for changes in older Emacs versions.
14 You can narrow news to a specific version by calling `view-emacs-news'
15 with a prefix argument or by typing C-u C-h C-n.
19 +++ indicates that the appropriate manual has already been updated.
20 --- means no change in the manuals is called for.
21 When you add a new item, please add it without either +++ or ---
22 so we will look at it and add it to the manual.
25 * Installation Changes in Emacs 24.1
27 ** Configure links against libselinux if it is found.
28 You can disable this by using --without-selinux.
31 ** By default, the installed Info and man pages are compressed.
32 You can disable this by configuring --without-compress-info.
35 ** There are new configure options:
36 --with-mmdf, --with-mail-unlink, --with-mailhost.
37 These provide no new functionality, they just remove the need to edit
38 lib-src/Makefile by hand in order to use the associated features.
41 ** Emacs can be compiled against Gtk+ 3.0 if you pass --with-x-toolkit=gtk3
42 to configure. Note that other libraries used by Emacs, RSVG and GConf,
43 also depend on Gtk+. You can disable them with --without-rsvg and
46 ** There is a new configure option --enable-use-lisp-union-type.
47 This is only useful for Emacs developers to debug certain types of bugs.
48 This is not a new feature; only the configure flag is new.
51 ** New translation of the Emacs Tutorial in Hebrew is available
52 Type `C-u C-h t' to choose it in case your language setup doesn't
53 automatically select it.
56 * Startup Changes in Emacs 24.1
58 ** The --unibyte, --multibyte, --no-multibyte, and --no-unibyte
59 command line arguments, and the EMACS_UNIBYTE environment variable, no
60 longer have any effect. (They were declared obsolete in Emacs 23.)
63 * Changes in Emacs 24.1
65 ** emacsclient changes
67 *** New emacsclient argument --parent-id ID can be used to open a
68 client frame in parent X window ID, via XEmbed. This works like the
69 --parent-id argument to Emacs.
71 *** If emacsclient shuts down as a result of Emacs signalling an
72 error, its exit status is 1.
74 ** Completion can cycle, depending on completion-cycle-threshold.
76 ** auto-mode-case-fold is now enabled by default.
79 ** Emacs now supports display and editing of bidirectional text.
81 See the node "Bidirectional Editing" in the Emacs Manual for some
82 initial documentation.
84 To turn this on in any given buffer, set the buffer-local variable
85 `bidi-display-reordering' to a non-nil value. The default is nil.
87 The buffer-local variable `bidi-paragraph-direction', if non-nil,
88 forces each paragraph in the buffer to have its base direction
89 according to the value of this variable. Possible values are
90 `right-to-left' and `left-to-right'. If the value is nil (the
91 default), Emacs determines the base direction of each paragraph from
92 its text, as specified by the Unicode Bidirectional Algorithm.
94 The function `current-bidi-paragraph-direction' returns the actual
95 value of paragraph base direction at point.
97 Reordering of bidirectional text for display in Emacs is a "Full
98 bidirectionality" class implementation of the Unicode Bidirectional
101 Note that some advanced display features, such as overlay strings and
102 `display' text properties, do not yet work correctly when
103 bidirectional text is reordered for display.
105 ** GTK scroll-bars are now placed on the right by default.
106 Use `set-scroll-bar-mode' to change this.
108 ** GTK tool bars can have just text, just images or images and text.
109 Customize `tool-bar-style' to choose style. On a Gnome desktop, the default
110 is taken from the desktop settings.
112 ** GTK tool bars can be placed on the left/right or top/bottom of the frame.
113 The frame-parameter tool-bar-position controls this. It takes the values
114 top, left, right or bottom. The Options => Show/Hide menu has entries
117 ** ImageMagick support.
118 It is now possible to use the ImageMagick library to load many new
119 image formats in Emacs. By default, Emacs links with the ImageMagick
120 libraries if they are present at build time. To disable this, use
121 the configure option `--without-imagemagick'.
123 The new function `imagemagick-types' returns a list of image file
124 extensions that your installation of ImageMagick supports. The
125 function `imagemagick-register-types' enables ImageMagick support for
126 these image types, minus those listed in `imagemagick-types-inhibit'.
128 See the Emacs Lisp Reference Manual for more information.
130 ** The colors for selected text (the region face) are taken from the GTK
131 theme when Emacs is built with GTK.
133 ** Emacs uses GTK tooltips by default if built with GTK. You can turn that
134 off by customizing x-gtk-use-system-tooltips.
136 ** Lucid menus and dialogs can display antialiased fonts if Emacs is built
137 with Xft. To change font, use X resource faceName, for example:
138 Emacs.pane.menubar.faceName: Courier-12
139 Set faceName to none and use font to use the old X fonts.
142 ** Enhanced support for characters that have no glyphs in available fonts
143 If a character has no glyphs in any of the available fonts, Emacs by
144 default will display it either as a hexadecimal code in a box or as a
145 thin 1-pixel space. In addition to these two methods, Emacs can
146 display these characters as empty box, as an acronym, or not display
147 them at all. To change how these characters are displayed, customize
148 the variable `glyphless-char-display-control'.
150 On character terminals these methods are used for characters that
151 cannot be encoded by the `terminal-coding-system'.
153 ** On graphical displays, the mode-line no longer ends in dashes.
155 ** Basic SELinux support has been added.
156 This requires Emacs to be linked with libselinux at build time.
158 *** Emacs preserves the SELinux file context when backing up, and
159 optionally when copying files. To this end, copy-file has an extra
160 optional argument, and backup-buffer and friends include the SELinux
161 context in their return values.
163 *** The new functions file-selinux-context and set-file-selinux-context
164 get and set the SELinux context of a file.
166 *** Tramp offers handlers for file-selinux-context and set-file-selinux-context
167 for remote machines which support SELinux.
169 ** The function kill-emacs is now run upon receipt of the signals SIGTERM
170 and SIGHUP, and upon SIGINT in batch mode.
172 ** kill-emacs-hook is now also run in batch mode.
174 ** New scrolling commands `scroll-up-command' and `scroll-down-command'
175 (bound to C-v/[next] and M-v/[prior]) does not signal errors at top/bottom
176 of buffer at first key-press (instead moves to top/bottom of buffer)
177 when a new variable `scroll-error-top-bottom' is non-nil.
179 ** New scrolling commands `scroll-up-line' and `scroll-down-line'
180 scroll a line instead of full screen.
182 ** New property `scroll-command' should be set on a command's symbol to
183 define it as a scroll command affected by `scroll-preserve-screen-position'.
187 *** `delete-by-moving-to-trash' now only affects commands that specify
188 trashing. This avoids inadvertently trashing temporary files.
190 *** Calling `delete-file' or `delete-directory' with a prefix argument
191 now forces true deletion, regardless of `delete-by-moving-to-trash'.
193 ** New option `list-colors-sort' defines the color sort order
194 for `list-colors-display'.
196 ** An Emacs Lisp package manager is now included.
197 This is a convenient way to download and install additional packages,
198 from a package repository at elpa.gnu.org.
200 *** `M-x list-packages' shows a list of packages, which can be
201 selected for installation.
203 *** New command `describe-package', bound to `C-h P'.
205 *** By default, all installed packages are loaded and activated
206 automatically when Emacs starts up. To disable this, set
207 `package-enable-at-startup' to nil. To change which packages are
208 loaded, customize `package-load-list'.
212 *** `M-x customize-themes' lists Custom themes which can be enabled.
214 *** New option `custom-theme-load-path' is the load path for themes.
215 Emacs no longer looks for custom themes in `load-path'. The default
216 is to search in `custom-theme-directory', followed by a built-in theme
217 directory named "themes/" in `data-directory'.
219 ** The user option `remote-file-name-inhibit-cache' controls whether
220 the remote file-name cache is used for read access.
222 ** The standalone programs lib-src/digest-doc and sorted-doc have been
223 replaced with Lisp commands `doc-file-to-man' and `doc-file-to-info'.
226 * Editing Changes in Emacs 24.1
229 ** There is a new command `count-words-region', which does what you expect.
231 ** completion-at-point is now an alias for complete-symbol.
233 ** The default value of `backup-by-copying-when-mismatch' is now t.
237 *** New option `delete-active-region'.
238 If non-nil, C-d, [delete], and DEL delete the region if it is active
239 and no prefix argument is given. If set to `kill', these commands
242 *** New command `delete-forward-char', bound to C-d and [delete].
243 This is meant for interactive use, and obeys `delete-active-region'.
244 The command `delete-char' does not obey `delete-active-region'.
246 *** `delete-backward-char' is now a Lisp function.
247 Apart from obeying `delete-active-region', its behavior is unchanged.
248 However, the byte compiler now warns if it is called from Lisp; you
249 should use delete-char with a negative argument instead.
251 *** The option `mouse-region-delete-keys' has been deleted.
253 ** Selection changes.
255 The default handling of clipboard and primary selections has been
256 changed to conform with other X applications. The exact changes are
257 described below; in short, mouse commands to select and paste text now
258 use the primary selection, while all other commands for killing and
259 yanking text now use the clipboard.
261 *** Merely selecting text (e.g. with drag-mouse-1) does not add it to
262 the kill-ring. On systems with a primary selection separate from the
263 clipboard (such as X), the selected text is put in the primary
266 *** mouse-2 is now bound to `mouse-yank-primary', which pastes from
267 the primary selection regardless of the contents of the kill-ring.
269 *** Commands that kill text or copy it to the kill-ring (M-w, C-w,
270 C-k, etc.) also put the killed text into the clipboard. This change
271 also means that the "Copy", "Cut", and "Paste" items in the "Edit"
272 menu are now exactly equivalent to, respectively M-w, C-w, and C-y.
274 *** Yank commands, such as C-y and M-y, retrieve text from the
275 clipboard if it is available.
277 *** The above changes are reflected in the following new defaults:
279 **** `select-active-regions' now defaults to t.
280 It also accepts a new value, `only', which means to only set the
281 primary selection for temporarily active regions (usually made by
282 mouse-dragging or shift-selection).
284 **** `mouse-2' is now bound to `mouse-yank-primary'.
285 Previously, it was bound to `mouse-yank-at-click' (which is now
288 **** `x-select-enable-clipboard' now defaults to t on all platforms.
289 Note that this variable was already non-nil by default on MS-Windows,
290 which does not support the primary selection between applications.
292 **** `x-select-enable-primary' now defaults to nil.
293 This variable exists only on X; its default value was t in previous
296 **** `mouse-drag-copy-region' now defaults to nil.
298 *** To return to the previous behavior, where mouse commands use the
299 clipboard, change `mouse-drag-copy-region' and (on X only)
300 `x-select-enable-primary' to t. If you don't want Emacs to put the
301 text into the clipboard, only to the primary selection, additionally
302 set `x-select-enable-clipboard' to nil.
304 *** Support for X cut buffers has been removed.
307 * Changes in Specialized Modes and Packages in Emacs 24.1
309 ** shell-mode can track your cwd by reading it from your prompt.
310 Just set shell-dir-cookie-re to an appropriate regexp.
312 ** Modula-2 mode provides auto-indentation.
314 ** latex-electric-env-pair-mode keeps \begin..\end matched on the fly.
316 ** FIXME: xdg-open for browse-url and reportbug, 2010/08.
318 ** Archive Mode has basic support to browse 7z archives.
320 ** browse-url has gotten a new variable that is used for mailto: URLs,
321 `browse-url-mailto-function', which defaults to `browse-url-mail'.
325 *** New vars `erc-autojoin-timing' and `erc-autojoin-delay'.
326 If the value of `erc-autojoin-timing' is 'ident, ERC autojoins after a
327 successful NickServ identification, or after `erc-autojoin-delay'
328 seconds. The default value, 'ident, means to autojoin immediately
331 *** New variable `erc-coding-system-precedence': If we use `undecided'
332 as the server coding system, this variable will then be consulted.
333 The default is to decode strings that can be decoded as utf-8 as
334 utf-8, and do the normal `undecided' decoding for the rest.
336 ** In ido-mode, C-v is no longer bound to ido-toggle-vc.
337 The reason is that this interferes with cua-mode.
339 ** partial-completion-mode is now obsolete.
340 You can get a comparable behavior with:
341 (setq completion-styles '(partial-completion initials))
342 (setq completion-pcm-complete-word-inserts-delimiters t)
344 ** mpc.el: Can use pseudo tags of the form tag1|tag2 as a union of two tags.
346 ** server can listen on a specific port using the server-port option.
348 ** Calendar, Diary, and Appt
351 *** The obsolete (since Emacs 22.1) method of enabling the appt package
352 by adding appt-make-list to diary-hook has been removed. Use appt-activate.
355 *** Some appt variables (obsolete since Emacs 22.1) have been removed:
356 appt-issue-message (use the function appt-activate)
357 appt-visible/appt-msg-window (use the variable appt-display-format)
360 *** Some diary function aliases (obsolete since Emacs 22.1) have been removed:
361 view-diary-entries, list-diary-entries, show-all-diary-entries
365 *** Customize buffers now contain a search field.
366 The search is performed using `customize-apropos'.
367 To turn off the search field, set custom-search-field to nil.
369 *** Custom options now start out hidden if at their default values.
370 Use the arrow to the left of the option name to toggle visibility.
372 *** custom-buffer-sort-alphabetically now defaults to t.
374 *** The color widget now has a "Choose" button, which allows you to
375 choose a color via list-colors-display.
379 *** dired-jump and dired-jump-other-window called with a prefix argument
380 read a file name from the minibuffer instead of using buffer-file-name.
382 ** Directory local variables can apply to file-less buffers.
383 For example, adding "(diff-mode . ((mode . whitespace)))" to your
384 .dir-locals.el file, will turn on `whitespace-mode' for *vc-diff* buffers.
386 ** SQL Mode enhancements.
388 *** Several variables have been marked as safe local variables. The
389 variables `sql-product', `sql-user', `sql-server', `sql-database' and
390 `sql-port' can now be safely used as local variables.
392 *** `sql-dialect' is a synonym for `sql-product'.
394 *** Added ability to login with a port on MySQL and Postgres.
395 The custom variable `sql-port' can be specified for connection to
396 MySQL or Postgres servers. By default, the port is not listed in
397 either login parameter, but will be added to the command line if set
400 *** Dynamic selection of product in an SQL interactive session.
401 If you use `sql-product-interactive' to start an SQL interactive
402 session it uses the current value of `sql-product'. Preceding the
403 invocation with C-u will force it to ask for the product before
404 creating the session.
406 *** Renaming a SQL interactive buffer when it is created.
407 Prefixing the SQL interactive commands (`sql-sqlite', `sql-postgres',
408 `sql-mysql', etc.) with C-u will force a new interactive session to be
409 started and will prompt for the new name. This will reduce the need
410 for `sql-rename-buffer' is most common use cases.
412 *** Command continuation prompts in SQL interactive mode are suppressed.
413 Multiple line commands in SQL interactive mode, generate command
414 continuation prompts which needlessly confuse the output. These
415 prompts are now filtered out from the output. This change impacts
416 multiple line SQL statements entered with C-j between each line,
417 statements yanked into the buffer and statements sent with
418 `sql-send-*' functions.
420 *** Custom variables control prompting for login parameters.
421 Each supported product has a custom variable `sql-*-login-params'
422 which is a list of the parameters to be prompted for before a
423 connection is established.
425 The lists consist of the following five tokens: `user', `password',
426 `database', `server', and `port'. The order in which they appear is
427 the order in which they are prompted. The tokens symbols can be
428 replaced by a sublist starting with the token and followed by a plist
429 which control the prompting for values. The tokens `user',
430 `database', and `server' each can take a property of :default which
431 specifies the value to be used if no value is entered. The
432 `database', `server', and `port' tokens handle the :completion
433 property which restricts the entry to either one of the values in the
434 list or to one of the values returned by the function provided as the
435 property value. The `database' and `server' tokens also accept the
436 :file property whose value is a regexp to identify useful file names.
439 (database :default DEF
441 :completion COMPLETE)
444 :completion COMPLETE)
446 The FILEPAT when :file is specified is a regexp that will match valid
447 file names (without the directory portion). Generally these strings
448 will be of the form ".+\.SUF" where SUF is the desired file suffix.
450 When :completion is specified, the COMPLETE corresponds to the
451 PREDICATE argument to the `completing-read' function (a list of
452 possible values or a function returning such a list).
454 *** Added `sql-connection-alist' to record login parameter values.
455 An alist for recording different username, database and server
456 values. If there are multiple databases that you connect to the
457 parameters needed can be stored in this alist.
459 For example, the following might be set in the user's init.el:
461 (setq sql-connection-alist
462 '((dev (sql-product 'sqlite)
463 (sql-database "/home/mmaug/dev.db"))
464 (prd (sql-product 'oracle)
466 (sql-database "iprd2a"))))
468 This defines two connections named "dev" and "prd".
470 *** Added `sql-connect' to use predefined connections.
471 Sets the login parameters based on the values in the
472 `sql-connection-alist' and start a SQL interactive session. Any
473 values specified in the connection will not be prompted for.
475 In the example above, if the user were to invoke M-x sql-connect, they
476 would be prompted for the connection. The user can respond with
477 either "dev" or "prd". The "dev" connection would connect to the
478 SQLite database without prompting; the "prd" connection would prompt
479 for the users password and then connect to the Oracle database.
481 **** Added SQL->Start... submenu when connections are defined.
482 When connections have been defined, there is a submenu available that
483 allows the user to select one to start a SQLi session. The "Start
484 SQLi Session" item moves to the "Start..." submenu when cnnections
487 **** Added "Save Connection" menu item in SQLi buffers.
488 When a SQLi session is not started by a connection then
489 `sql-save-connection' will gather the login params specified for the
490 session and save them as a new connection.
492 *** List database objects and details.
493 Once a SQL interactive session has been started, you can get a list of
494 the objects in the database and see details of those objects. The
495 objects shown and the details available are product specific.
497 **** List all objects.
498 Using `M-x sql-list-all', `C-c C-l a' or selecting "SQL->List all
499 objects" will list all the objects in the database. At a minimum it
500 lists the tables and views in the database. Preceeding the command by
501 universal argument may provide additional details or extend the
502 listing to include other schemas objects. The list will appear in a
503 separate window in view-mode.
505 **** List Table details.
506 Using `M-x sql-list-table', `C-c C-l t' or selecting "SQL->List Table
507 details" will ask for the name of a database table or view and display
508 the list of columns in the relation. Preceeding the comand with the
509 universal argument may provide additional details about each column.
510 The list will appear in a separate window in view-mode.
512 *** Added option `sql-send-terminator'.
513 When set makes sure that each command sent with `sql-send-*' commands
514 are properly terminated and submitted to the SQL processor.
516 *** Added option `sql-oracle-scan-on'.
517 When set commands sent to Oracle's SQL*Plus are scanned for strings
518 starting with an ampersand and the user is asked for replacement text.
519 In general, the SQL*Plus option SCAN should always be set OFF under
520 SQL interactive mode and this option used in its place.
522 *** SQL interactive mode will replace tabs with spaces.
523 This prevents the comand interpretter for MySQL and Postgres from
524 listing object name completions when being sent text via
525 `sql-send-*' functions.
527 *** An API for manipulating SQL product definitions has been added.
529 ** s-region.el is now declared obsolete, superceded by shift-select-mode
530 enabled by default in 23.1.
534 *** GDB User Interface migrated to GDB Machine Interface and now
535 supports multithread non-stop debugging and debugging of several
536 threads simultaneously.
540 *** It is possible now, to access alternative buses than the default
541 system or session bus.
545 *** The following access methods are discontinued: "ssh1_old",
546 "ssh2_old", "scp1_old", "scp2_old" and "fish".
548 ** VC and related modes
550 *** Support for pulling on distributed version control systems.
551 The vc-update command now runs a "pull" operation, if it is supported.
552 This updates the current branch from upstream. A prefix argument
553 means to prompt the user for command specifics, e.g. a pull location.
555 **** vc-pull is an alias for vc-update.
557 **** Currently supported by Bzr.
559 *** Support for merging on distributed version control systems.
560 The vc-merge command now runs a "merge" operation, if it is supported.
561 This merges another branch into the current one. A prefix argument
562 means to prompt the user for command specifics, e.g. a merge location.
564 **** Currently supported by Bzr.
567 * New Modes and Packages in Emacs 24.1
569 ** New global minor modes electric-pair-mode, electric-indent-mode,
570 and electric-layout-mode.
572 ** pcase.el provides the ML-style pattern matching macro `pcase'.
574 ** secrets.el is an implementation of the Secret Service API, an
575 interface to password managers like GNOME Keyring or KDE Wallet. The
576 Secret Service API requires D-Bus for communication. The command
577 `secrets-show-secrets' offers a buffer with a visualization of the
580 ** notifications.el provides an implementation of the Desktop
581 Notifications API. It requires D-Bus for communication.
584 * Incompatible Lisp Changes in Emacs 24.1
586 ** For mouse click input events in the text area, the Y pixel
587 coordinate in the POSITION list now counts from the top of the text
588 area, excluding any header line. Previously, it counted from the top
591 ** Remove obsolete name `e' (use `float-e' instead).
593 ** A backquote not followed by a space is now always treated as new-style.
595 ** Test for special mode-class was moved from view-file to view-buffer.
596 FIXME: This only says what was changed, but not what are the
597 programmer-visible consequences.
599 ** Passing a nil argument to a minor mode function now turns the mode
602 ** During startup, Emacs no longer adds entries for `menu-bar-lines'
603 and `tool-bar-lines' to `default-frame-alist' and
604 `initial-frame-alist'. With these alist entries omitted, `make-frame'
605 checks the value of the variable `menu-bar-mode'/`tool-bar-mode' to
606 determine whether to create a menu-bar or tool-bar, respectively.
607 If the alist entries are added, they override the value of
608 `menu-bar-mode'/`tool-bar-mode'.
610 ** Regions created by mouse dragging are now normal active regions,
611 similar to the ones created by shift-selection. In previous Emacs
612 versions, these regions were delineated by `mouse-drag-overlay', which
613 has now been removed.
615 ** cl.el no longer provides `cl-19'.
617 ** The following functions and aliases, obsolete since at least Emacs 21.1,
619 comint-kill-output, decompose-composite-char, outline-visible,
620 internal-find-face, internal-get-face, frame-update-faces,
621 frame-update-face-colors, x-frob-font-weight, x-frob-font-slant,

628 ** The following variables and aliases, obsolete since at least Emacs 21.1,
630 checkdoc-minor-keymap, vc-header-alist, directory-sep-char,
631 font-lock-defaults-alist
633 ** The following files, obsolete since at least Emacs 21.1, have been removed:
634 sc.el, x-menu.el, rnews.el, rnewspost.el
636 ** FIXME finder-inf.el changes.
639 * Lisp changes in Emacs 24.1
641 ** `image-library-alist' is renamed to `dynamic-library-alist'.
642 The variable is now used to load all kind of supported dynamic libraries,
643 not just image libraries. The previous name is still available as an
646 ** New variable syntax-propertize-function to set syntax-table properties.
647 Replaces font-lock-syntactic-keywords which are now obsolete.
648 This allows syntax-table properties to be set independently from font-lock:
649 just call syntax-propertize to make sure the text is propertized.
650 Together with this new variable come a new hook
651 syntax-propertize-extend-region-functions, as well as two helper functions:
652 syntax-propertize-via-font-lock to reuse old font-lock-syntactic-keywords
653 as-is; and syntax-propertize-rules which provides a new way to specify
656 ** New hook post-self-insert-hook run at the end of self-insert-command.
659 ** Syntax tables support a new "comment style c" additionally to style b.
660 ** frame-local variables cannot be let-bound any more.
661 ** prog-mode is a new major-mode meant to be the parent of programming mode.
662 ** define-minor-mode accepts a new keyword :variable.
664 ** `delete-file' and `delete-directory' now accept optional arg TRASH.
665 Trashing is performed if TRASH and `delete-by-moving-to-trash' are
666 both non-nil. Interactively, TRASH defaults to t, unless a prefix
667 argument is supplied (see Trash changes, above).
669 ** buffer-substring-filters is obsoleted by filter-buffer-substring-functions.
671 ** New completion style `substring'.
673 ** `facemenu-read-color' is now an alias for `read-color'.
674 The command `read-color' now requires a match for a color name or RGB
675 triplet, instead of signalling an error if the user provides a invalid
681 *** When the image type is one of listed in `image-animated-types'
682 and the number of sub-images in the image is more than one, then the
683 new function `create-animated-image' creates an animated image where
684 sub-images are displayed successively with the duration defined by
685 `image-animate-max-time' and the delay between sub-images defined
686 by the Graphic Control Extension of the image.
688 *** `image-extension-data' is renamed to `image-metadata'.
690 ** XML and HTML parsing
692 *** If Emacs is compiled with libxml2 support (which is the default),
693 two new Emacs Lisp-level functions are defined:
694 `xml-parse-html-string-internal' (which will parse "real world" HTML)
695 and `xml-parse-string-internal' (which parses XML). Both return an
696 Emacs Lisp parse tree.
698 FIXME: These should be front-ended by xml.el.
704 *** New hook `isearch-update-post-hook' that runs in `isearch-update'.
706 ** Progress reporters can now "spin".
707 The MIN-VALUE and MAX-VALUE arguments of `make-progress-reporter' can
708 now be nil, or omitted. This makes a "non-numeric" reporter. Each
709 time you call `progress-reporter-update' on that progress reporter,
710 with a nil or omitted VALUE argument, the reporter message is
711 displayed with a "spinning bar".
714 * Changes in Emacs 24.1 on non-free operating systems
716 ** New configure.bat option --enable-checking builds emacs with extra
719 ** New configure.bat option --distfiles to specify files to be
720 included in binary distribution
722 ** New make target `dist' to create binary disttribution for Windows
