GM
27** Configure links against libselinux if it is found.
28You can disable this by using --without-selinux.
29
30---
31** By default, the installed Info and man pages are compressed.
32You can disable this by configuring --without-compress-info.
33
aded53ff
GM
34---
35** There are new configure options:
36--with-mmdf, --with-mail-unlink, --with-mailhost.
37These provide no new functionality, they just remove the need to edit
38lib-src/Makefile by hand in order to use the associated features.
39
1ddac986
GM
40---
41** There is a new configure option --with-crt-dir.
42This is only useful if your crt*.o files are in a non-standard location.
43
e547b051 44---
30c4d8dc 45** Emacs can be compiled against Gtk+ 3.0 if you pass --with-x-toolkit=gtk3
e547b051
J
46to configure. Note that other libraries used by Emacs, RSVG and GConf,
47also depend on Gtk+. You can disable them with --without-rsvg and
48--without-gconf.
49
d9170db5
DN
50** There is a new configure option --enable-use-lisp-union-type.
51This is only useful for Emacs developers to debug certain types of bugs.
b2957ea8 52This is not a new feature; only the configure flag is new.
d9170db5 53

54---
55** New translation of the Emacs Tutorial in Hebrew is available
56Type `C-u C-h t' to choose it in case your language setup doesn't
57automatically select it.

eb199145 60* Startup Changes in Emacs 24.1
4a263588 61
198a7a97
CY
62** The --unibyte, --multibyte, --no-multibyte, and --no-unibyte
63command line arguments no longer have any effect. (They were declared
64obsolete in Emacs 23.)

eb199145 67* Changes in Emacs 24.1
7841339b 68
2a847524
CY
69** emacsclient changes
70
71*** New emacsclient argument --parent-id ID can be used to open a
0191e222
CY
72client frame in parent X window ID, via XEmbed. This works like the
73--parent-id argument to Emacs.
74
2a847524
CY
75*** If emacsclient shuts down as a result of Emacs signalling an
76error, its exit status is 1.
77
902a6d8d
SM
78** Completion can cycle, depending on completion-cycle-threshold.
79
2372f278
SM
80** auto-mode-case-fold is now enabled by default.
81
f4b6ba46
EZ
82+++
83** Emacs now supports display and editing of bidirectional text.
f4b6ba46
EZ
84
85See the node "Bidirectional Editing" in the Emacs Manual for some
86initial documentation.
87
88To turn this on in any given buffer, set the buffer-local variable
89`bidi-display-reordering' to a non-nil value. The default is nil.
90
91The buffer-local variable `bidi-paragraph-direction', if non-nil,
92forces each paragraph in the buffer to have its base direction
93according to the value of this variable. Possible values are
94`right-to-left' and `left-to-right'. If the value is nil (the
95default), Emacs determines the base direction of each paragraph from
96its text, as specified by the Unicode Bidirectional Algorithm.
97
d20e1419
EZ
98The function `current-bidi-paragraph-direction' returns the actual
99value of paragraph base direction at point.
100
f4b6ba46
EZ
101Reordering of bidirectional text for display in Emacs is a "Full
102bidirectionality" class implementation of the Unicode Bidirectional
103Algorithm.
104
46759717
EZ
105Note that some advanced display features, such as overlay strings and
106`display' text properties, do not yet work correctly when
107bidirectional text is reordered for display.
108
303500aa 109** GTK scroll-bars are now placed on the right by default.
52834b6b
CY
110Use `set-scroll-bar-mode' to change this.
111
20fe03ad 112** GTK tool bars can have just text, just images or images and text.
d8004abe 113Customize `tool-bar-style' to choose style. On a Gnome desktop, the default
20fe03ad
JD
114is taken from the desktop settings.
115
8b2dd508
JD
116** GTK tool bars can be placed on the left/right or top/bottom of the frame.
117The frame-parameter tool-bar-position controls this. It takes the values
1c0d77cc 118top, left, right or bottom. The Options => Show/Hide menu has entries
8b2dd508
JD
119for this.
120
8740c12d 121** ImageMagick support.
b2fa3a09
GM
122It is now possible to use the ImageMagick library to load many new
123image formats in Emacs. By default, Emacs links with the ImageMagick
124libraries if they are present at build time. To disable this, use
8ea189f7 125the configure option `--without-imagemagick'.
16a91140 126
8740c12d
GM
127The new function `imagemagick-types' returns a list of image file
128extensions that your installation of ImageMagick supports. The
129function `imagemagick-register-types' enables ImageMagick support for
b2957ea8 130these image types, minus those listed in `imagemagick-types-inhibit'.
16a91140 131
8740c12d 132See the Emacs Lisp Reference Manual for more information.
16a91140 133
3a46642b
J
134** The colors for selected text (the region face) are taken from the GTK
135theme when Emacs is built with GTK.
136
aa1859f5
J
137** Emacs uses GTK tooltips by default if built with GTK. You can turn that
138off by customizing x-gtk-use-system-tooltips.
139
1ecb2d3f 140** Lucid menus and dialogs can display antialiased fonts if Emacs is built
a6ac7fc4
JD
141with Xft. To change font, use X resource faceName, for example:
142Emacs.pane.menubar.faceName: Courier-12
143Set faceName to none and use font to use the old X fonts.
99852628 144
917794d5
CY
145** On graphical displays, the mode-line no longer ends in dashes.
146
b7d65a5f
GM
147** Basic SELinux support has been added.
148This requires Emacs to be linked with libselinux at build time.
149
d8004abe
GM
150*** Emacs preserves the SELinux file context when backing up, and
151optionally when copying files. To this end, copy-file has an extra
152optional argument, and backup-buffer and friends include the SELinux
153context in their return values.
b7d65a5f
GM
154
155*** The new functions file-selinux-context and set-file-selinux-context
156get and set the SELinux context of a file.
157
a5bee597
MA
158*** Tramp offers handlers for file-selinux-context and set-file-selinux-context
159for remote machines which support SELinux.
160
9c524fcb 161** The function kill-emacs is now run upon receipt of the signals SIGTERM
383ebd15 162and SIGHUP, and upon SIGINT in batch mode.
9c524fcb
GM
163
164** kill-emacs-hook is now also run in batch mode.
165
79ce172a 166** New scrolling commands `scroll-up-command' and `scroll-down-command'
7b05466f
JL
167(bound to C-v/[next] and M-v/[prior]) does not signal errors at top/bottom
168of buffer at first key-press (instead moves to top/bottom of buffer)
169when a new variable `scroll-error-top-bottom' is non-nil.
79ce172a 170
5a97d2da
JL
171** New scrolling commands `scroll-up-line' and `scroll-down-line'
172scroll a line instead of full screen.
173
a4b000fb 174** New property `scroll-command' should be set on a command's symbol to
b2957ea8 175define it as a scroll command affected by `scroll-preserve-screen-position'.
9013a7f8 176
f1a5d776
CY
177** Trash changes
178
179*** `delete-by-moving-to-trash' now only affects commands that specify
180trashing. This avoids inadvertently trashing temporary files.
181
182*** Calling `delete-file' or `delete-directory' with a prefix argument
183now forces true deletion, regardless of `delete-by-moving-to-trash'.
184
f0bf7c8e
JL
185** New option `list-colors-sort' defines the color sort order
186for `list-colors-display'.
187
44198b6e
CY
188** An Emacs Lisp package manager is now included.
189This is a convenient way to download and install additional packages,
cb6c4991
CY
190from elpa.gnu.org.
191
192*** `M-x list-packages' shows a list of packages, which can be
193selected for installation.
194
195*** New command `describe-package', bound to `C-h P'.
44198b6e
CY
196
197*** By default, all installed packages are loaded and activated
198automatically when Emacs starts up. To disable this, set
199`package-enable-at-startup' to nil. To change which packages are
200loaded, customize `package-load-list'.
201
f065864f
CY
202** Custom Themes
203
204*** `M-x customize-themes' lists Custom themes which can be enabled.
205
782b5e8d
CY
206*** New option `custom-theme-load-path' is the load path for themes.
207Emacs no longer looks for custom themes in `load-path'. The default
208is to search in `custom-theme-directory', followed by a built-in theme
209directory named "themes/" in `data-directory'.
210
4ddf410a
MA
211** The user option `remote-file-name-inhibit-cache' controls whether
212the remote file-name cache is used for read access.
213
17284e30
GM
214** The standalone programs lib-src/digest-doc and sorted-doc have been
215replaced with Lisp commands `doc-file-to-man' and `doc-file-to-info'.

eb199145 218* Editing Changes in Emacs 24.1
b350bdf2 219
a982c7ec
CY
220** completion-at-point is now an alias for complete-symbol.
221
b9229673
CY
222** Deletion changes
223
224*** New option `delete-active-region'.
225If non-nil, C-d, [delete], and DEL delete the region if it is active
226and no prefix argument is given. If set to `kill', these commands
227kill instead.
228
229*** New command `delete-forward-char', bound to C-d and [delete].
230This is meant for interactive use, and obeys `delete-active-region';
231delete-char, meant for Lisp, does not obey `delete-active-region'.
232
233*** `delete-backward-char' is now a Lisp function.
234Apart from obeying `delete-active-region', its behavior is unchanged.
235However, the byte compiler now warns if it is called from Lisp; you
236should use delete-char with a negative argument instead.
237
238*** The option `mouse-region-delete-keys' has been deleted.
239
f9d71b42
CY
240** Selection changes.
241
7c23dd44
CY
242The default handling of clipboard and primary selections has been
243changed to conform with other X applications.
f9d71b42 244
4c0f50c9
EZ
245The new behavior is that by default Emacs does not put selected text
246into the clipboard, and does not add it to kill-ring, merely because
247the text was selected. Only commands that kill text or copy it to the
7c9b11be
EZ
248kill-ring (C-w, M-w, C-k, etc.) put the killed text into the
249clipboard. Selected text is put into the primary selection (on
250systems, such as X, that support the primary selection separately from
251the clipboard).
252
253Similarly, Emacs by default does not retrieve text from the clipboard
254when the mouse (e.g., mouse-2) is used for pasting text selected in
4c0f50c9
EZ
255another application. Mouse commands that paste text retrieve text
256from the primary selection, on systems that support it separately from
257the clipboard. Text from the clipboard is retrieved only by C-y, M-y
258and other commands that yank text from the kill-ring.
7c9b11be
EZ
259
260In other words, the default behavior is that mouse gestures that
4c0f50c9
EZ
261select and paste text work with the primary selection (on X), while
262keyboard commands that kill/copy and paste text work with the
263clipboard.
7c9b11be
EZ
264
265This change also means that the "Copy", "Cut", and "Paste" items of
266the menu-bar "Edit" menu are now exactly equivalent to, respectively
267M-w, C-w, and C-y.
268
269To get back the previous behavior, whereby mouse gestures set the
270clipboard and retrieve text from there, customize the variables
4c0f50c9
EZ
271`mouse-drag-copy-region' and (on X only) `x-select-enable-primary' to
272non-nil values. If you don't want Emacs to put the text into the
273clipboard, only to the primary selection, additionally customize
7c9b11be
EZ
274`x-select-enable-clipboard' to nil.
275
276These changes in the default behavior are reflected in the default
277values of several variables:
278
7c23dd44 279*** `select-active-regions' now defaults to t, so active regions set
7c9b11be 280the primary selection. It was nil in previous versions.
7c23dd44 281
d1b08c88 282It also accepts a new value, `only', which means to only set the
7c23dd44
CY
283primary selection for temporarily active regions (usually made by
284mouse-dragging or shift-selection).
285
286*** `mouse-2' is now bound to `mouse-yank-primary'.
7c9b11be 287Previously, it was bound to `mouse-yank-at-click' (which is now
4c0f50c9 288unbound by default).
f9d71b42 289
7c9b11be 290*** `x-select-enable-clipboard' now defaults to t on all platforms.
7c23dd44 291Thus, killing and yanking now use the clipboard (in addition to the
7c9b11be
EZ
292kill ring). Note that this variable was already non-nil by default on
293MS-Windows, which does not support the primary selection between
294applications.
f9d71b42 295
2490cbbc 296*** `x-select-enable-primary' now defaults to nil.
7c9b11be
EZ
297This variable exists only on X; its default value was t in previous
298versions.
2490cbbc 299
f9d71b42 300*** `mouse-drag-copy-region' now defaults to nil.
7c9b11be 301Its previous default value was t.
f9d71b42 302
084e6df3
JD
303*** Support for X cut buffers has been removed.
304

eb199145 306* Changes in Specialized Modes and Packages in Emacs 24.1
efeb796b 307
b879a6e2
SM
308** latex-electric-env-pair-mode keeps \begin..\end matched on the fly.
309
360ac530 310** FIXME: xdg-open for browse-url and reportbug, 2010/08.
0ac3effe 311
b3671a51
JL
312** Archive Mode has basic support to browse 7z archives.
313
8a8d54cd
VD
314** ERC changes
315
316*** New vars `erc-autojoin-timing' and `erc-autojoin-delay'.
317If the value of `erc-autojoin-timing' is 'ident, ERC autojoins after a
318successful NickServ identification, or after `erc-autojoin-delay'
319seconds. The default value, 'ident, means to autojoin immediately
320after connecting.
321
27d3cd56
CY
322** In ido-mode, C-v is no longer bound to ido-toggle-vc.
323The reason is that this interferes with cua-mode.
324
c1e25821 325** partial-completion-mode is now obsolete.
79ccd68f
SM
326You can get a comparable behavior with:
327(setq completion-styles '(partial-completion initials))
328(setq completion-pcm-complete-word-inserts-delimiters t)
c1e25821 329
18c812bd 330** mpc.el: Can use pseudo tags of the form tag1|tag2 as a union of two tags.
b2957ea8 331
1d83b0e9
GM
332** server can listen on a specific port using the server-port option.
333
cf16af42
GM
334** Calendar, Diary, and Appt
335
336---
337*** The obsolete (since Emacs 22.1) method of enabling the appt package
338by adding appt-make-list to diary-hook has been removed. Use appt-activate.
339
340---
341*** Some appt variables (obsolete since Emacs 22.1) have been removed:
342appt-issue-message (use the function appt-activate)
343appt-visible/appt-msg-window (use the variable appt-display-format)
344
345---
346*** Some diary function aliases (obsolete since Emacs 22.1) have been removed:
347view-diary-entries, list-diary-entries, show-all-diary-entries
348
52834b6b
CY
349** Customize
350
351*** Customize buffers now contain a search field.
352The search is performed using `customize-apropos'.
353To turn off the search field, set custom-search-field to nil .
354
355*** Custom options now start out hidden if at their default values.
356Use the arrow to the left of the option name to toggle visibility.
357
358*** custom-buffer-sort-alphabetically now defaults to t.
359
360*** The color widget now has a "Choose" button, which allows you to
361choose a color via list-colors-display.
362
f5d6548a
JL
363** Dired-x
364
365*** dired-jump and dired-jump-other-window called with a prefix argument
366read a file name from the minibuffer instead of using buffer-file-name.
367
855a2294
DN
368** VC and related modes
369
e97a42c1 370*** New VC commands: vc-log-incoming, vc-log-outgoing, vc-find-conflicted-file.
31527c56 371
6941ffec
DN
372**** vc-log-incoming for Git runs "git fetch" so that the necessary
373data is available locally.
374
eccdfe5f
DN
375**** vc-log-incoming and vc-log-outgoing for Git require version 1.7 (or newer).
376
54d3626e
DN
377*** New key bindings: C-x v I and C-x v O bound to vc-log-incoming and
378vc-log-outgoing, respectively.
379
1fbcf428
DN
380*** The 'g' key in VC diff, log, log-incoming and log-outgoing buffers
381reruns the corresponding VC command to compute an up to date version
382of the buffer.
383
855a2294
DN
384*** vc-dir for Bzr supports viewing shelve contents and shelving snapshots.
385
09158997 386*** Special markup can be added to log-edit buffers.
e97a42c1
SM
387The log-edit buffers are expected to have a format similar to email messages
388with headers of the form:
389 Author: <author of this change>
390 Summary: <one line summary of this change>
391 Fixes: <reference to the bug fixed by this change>
392Some backends handle some of those headers specially, but any unknown header
393is just left as is in the message, so it is not lost.
09158997 394
fab43c76
DN
395**** vc-git handles Author: and Date:
396**** vc-hg handles Author: and Date:
397**** vc-bzr handles Author:, Date: and Fixes:
398**** vc-mtn handles Author: and Date:
399
b3d42406
DN
400*** Pressing g in a *vc-diff* buffer reruns vc-diff, so it will
401produce an up to date diff.
402
8117868f
DN
403** Directory local variables can apply to file-less buffers.
404For example, adding "(diff-mode . ((mode . whitespace)))" to your
d8004abe 405.dir-locals.el file, will turn on `whitespace-mode' for *vc-diff* buffers.
8117868f 406
7492acc9
MM
407** SQL Mode enhancements.
408
30c4d8dc
MM
409*** Several variables have been marked as safe local variables. The
410variables `sql-product', `sql-user', `sql-server', `sql-database' and
411`sql-port' can now be safely used as local variables.
7492acc9 412
9250002f
MM
413*** `sql-dialect' is a synonym for `sql-product'.
414
74790210 415*** Added ability to login with a port on MySQL and Postgres.
7492acc9 416The custom variable `sql-port' can be specified for connection to
74790210
MM
417MySQL or Postgres servers. By default, the port is not listed in
418either login parameter, but will be added to the command line if set
419to a non-zero value.
7492acc9 420
9250002f
MM
421*** Dynamic selection of product in an SQL interactive session.
422If you use `sql-product-interactive' to start an SQL interactive
423session it uses the current value of `sql-product'. Preceding the
424invocation with C-u will force it to ask for the product before
425creating the session.
426
427*** Renaming a SQL interactive buffer when it is created.
428Prefixing the SQL interactive commands (`sql-sqlite', `sql-postgres',
429`sql-mysql', etc.) with C-u will force a new interactive session to be
430started and will prompt for the new name. This will reduce the need
431for `sql-rename-buffer' is most common use cases.
432
3bd2cfef
MM
433*** Command continuation prompts in SQL interactive mode are suppressed.
434Multiple line commands in SQL interactive mode, generate command
435continuation prompts which needlessly confuse the output. These
436prompts are now filtered out from the output. This change impacts
437multiple line SQL statements entered with C-j between each line,
438statements yanked into the buffer and statements sent with
439`sql-send-*' functions.
440
7492acc9
MM
441*** Custom variables control prompting for login parameters.
442Each supported product has a custom variable `sql-*-login-params'
443which is a list of the parameters to be prompted for before a
444connection is established.
445
74790210
MM
446The lists consist of the following five tokens: `user', `password',
447`database', `server', and `port'. The order in which they appear is
448the order in which they are prompted. The tokens symbols can be
449replaced by a sublist starting with the token and followed by a plist
450which control the prompting for values. The tokens `user',
451`database', and `server' each can take a property of :default which
452specifies the value to be used if no value is entered. The
453`database', `server', and `port' tokens handle the :completion
454property which restricts the entry to either one of the values in the
455list or to one of the values returned by the function provided as the
456property value. The `database' and `server' tokens also accept the
457:file property whose value is a regexp to identify useful file names.
458
459 (user :default DEF)
460 (database :default DEF
461 :file FILEPAT
462 :completion COMPLETE)
463 (server :default DEF
464 :file FILEPAT
465 :completion COMPLETE)
466
467The FILEPAT when :file is specified is a regexp that will match valid
468file names (without the directory portion). Generally these strings
469will be of the form ".+\.SUF" where SUF is the desired file suffix.
470
471When :completion is specified, the COMPLETE corresponds to the
472PREDICATE argument to the `completing-read' function (a list of
473possible values or a function returning such a list).
5474c40f 474
30c4d8dc
MM
475*** Added `sql-connection-alist' to record login parameter values.
476An alist for recording different username, database and server
477values. If there are multiple databases that you connect to the
478parameters needed can be stored in this alist.
479
480For example, the following might be set in the user's init.el:
481
482 (setq sql-connection-alist
483 '((dev (sql-product 'sqlite)
484 (sql-database "/home/mmaug/dev.db"))
485 (prd (sql-product 'oracle)
486 (sql-user "mmaug")
487 (sql-database "iprd2a"))))
488
489This defines two connections named "dev" and "prd".
490
491*** Added `sql-connect' to use predefined connections.
492Sets the login parameters based on the values in the
493`sql-connection-alist' and start a SQL interactive session. Any
494values specified in the connection will not be prompted for.
495
496In the example above, if the user were to invoke M-x sql-connect, they
497would be prompted for the connection. The user can respond with
498either "dev" or "prd". The "dev" connection would connect to the
499SQLite database without prompting; the "prd" connection would prompt
500for the users password and then connect to the Oracle database.
501
d26b0ea9 502**** Added SQL->Start... submenu when connections are defined.
b2957ea8 503When connections have been defined, there is a submenu available that
d26b0ea9
MM
504allows the user to select one to start a SQLi session. The "Start
505SQLi Session" item moves to the "Start..." submenu when cnnections
506have been defined.
507
508**** Added "Save Connection" menu item in SQLi buffers.
509When a SQLi session is not started by a connection then
510`sql-save-connection' will gather the login params specified for the
511session and save them as a new connection.
512
74790210
MM
513*** List database objects and details.
514Once a SQL interactive session has been started, you can get a list of
515the objects in the database and see details of those objects. The
516objects shown and the details available are product specific.
517
518**** List all objects.
519Using `M-x sql-list-all', `C-c C-l a' or selecting "SQL->List all
520objects" will list all the objects in the database. At a minimum it
521lists the tables and views in the database. Preceeding the command by
522universal argument may provide additional details or extend the
523listing to include other schemas objects. The list will appear in a
524separate window in view-mode.
525
526**** List Table details.
527Using `M-x sql-list-table', `C-c C-l t' or selecting "SQL->List Table
528details" will ask for the name of a database table or view and display
529the list of columns in the relation. Preceeding the comand with the
530universal argument may provide additional details about each column.
531The list will appear in a separate window in view-mode.
532
7492acc9
MM
533*** Added option `sql-send-terminator'.
534When set makes sure that each command sent with `sql-send-*' commands
535are properly terminated and submitted to the SQL processor.
536
537*** Added option `sql-oracle-scan-on'.
538When set commands sent to Oracle's SQL*Plus are scanned for strings
30c4d8dc
MM
539starting with an ampersand and the user is asked for replacement text.
540In general, the SQL*Plus option SCAN should always be set OFF under
541SQL interactive mode and this option used in its place.
7492acc9
MM
542
543*** SQL interactive mode will replace tabs with spaces.
544This prevents the comand interpretter for MySQL and Postgres from
545listing object name completions when being sent text via
546`sql-send-*' functions.
547
548*** An API for manipulating SQL product definitions has been added.
549
5e418f17
JL
550** s-region.el is now declared obsolete, superceded by shift-select-mode
551enabled by default in 23.1.

553** gdb-mi
554
555*** GDB User Interface migrated to GDB Machine Interface and now
556supports multithread non-stop debugging and debugging of several
557threads simultaneously.

600
601** During startup, Emacs no longer adds entries for `menu-bar-lines'
602and `tool-bar-lines' to `default-frame-alist' and
603`initial-frame-alist'. With these alist entries omitted, `make-frame'
604checks the value of the variable `menu-bar-mode'/`tool-bar-mode' to
605determine whether to create a menu-bar or tool-bar, respectively.
606If the alist entries are added, they override the value of
607`menu-bar-mode'/`tool-bar-mode'.
608

CY
609** Regions created by mouse dragging are now normal active regions,
610similar to the ones created by shift-selection. In previous Emacs
611versions, these regions were delineated by `mouse-drag-overlay', which

638* Lisp changes in Emacs 24.1
9097e8af 639
2e288d54
JB
640** `image-library-alist' is renamed to `dynamic-library-alist'.
641The variable is now used to load all kind of supported dynamic libraries,
642not just image libraries. The previous name is still available as an
643obsolete alias.
644
cf38dd42
SM
645** New variable syntax-propertize-function to set syntax-table properties.
646Replaces font-lock-syntactic-keywords which are now obsolete.
647This allows syntax-table properties to be set independently from font-lock:
648just call syntax-propertize to make sure the text is propertized.
649Together with this new variable come a new hook
650syntax-propertize-extend-region-functions, as well as two helper functions:
651syntax-propertize-via-font-lock to reuse old font-lock-syntactic-keywords
652as-is; and syntax-propertize-rules which provides a new way to specify
653syntactic rules.

4e2db1fe 659** frame-local variables cannot be let-bound any more.
10dcc561 660** prog-mode is a new major-mode meant to be the parent of programming mode.
f44379e7
SM
661** define-minor-mode accepts a new keyword :variable.
662
b2957ea8 663** `delete-file' and `delete-directory' now accept optional arg TRASH.
f1a5d776
CY
664Trashing is performed if TRASH and `delete-by-moving-to-trash' are
665both non-nil. Interactively, TRASH defaults to t, unless a prefix
666argument is supplied (see Trash changes, above).

670** New completion style `substring'.
671
9317e499
CY
672** `facemenu-read-color' is now an alias for `read-color'.
673The command `read-color' now requires a match for a color name or RGB
674triplet, instead of signalling an error if the user provides a invalid
675input.

678** Image API
679
680*** When the image type is one of listed in `image-animated-types'
1546c559 681and the number of sub-images in the image is more than one, then the
00fe2df1
JL
682new function `create-animated-image' creates an animated image where
683sub-images are displayed successively with the duration defined by
684`image-animate-max-time' and the delay between sub-images defined
685by the Graphic Control Extension of the image.

689** XML and HTML parsing
690
691*** If Emacs is compiled with libxml2 support (which is the default),
4b9832a6
CY
692two new Emacs Lisp-level functions are defined:
693`xml-parse-html-string-internal' (which will parse "real world" HTML)
694and `xml-parse-string-internal' (which parses XML). Both return an
695Emacs Lisp parse tree.
696
697FIXME: These should be front-ended by xml.el.

9326ba26
CY
705** Progress reporters can now "spin".
706The MIN-VALUE and MAX-VALUE arguments of `make-progress-reporter' can
707now be nil, or omitted. This makes a "non-numeric" reporter. Each
708time you call `progress-reporter-update' on that progress reporter,
709with a nil or omitted VALUE argument, the reporter message is
710displayed with a "spinning bar".
