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
e547b051 40---
30c4d8dc 41** Emacs can be compiled against Gtk+ 3.0 if you pass --with-x-toolkit=gtk3
e547b051
J
42to configure. Note that other libraries used by Emacs, RSVG and GConf,
43also depend on Gtk+. You can disable them with --without-rsvg and
44--without-gconf.
45
d9170db5
DN
46** There is a new configure option --enable-use-lisp-union-type.
47This is only useful for Emacs developers to debug certain types of bugs.
b2957ea8 48This is not a new feature; only the configure flag is new.

eb199145 56* Startup Changes in Emacs 24.1
4a263588 57
198a7a97
CY
58** The --unibyte, --multibyte, --no-multibyte, and --no-unibyte
59command line arguments no longer have any effect. (They were declared
60obsolete in Emacs 23.)

eb199145 63* Changes in Emacs 24.1
7841339b 64
2a847524
CY
65** emacsclient changes
66
67*** New emacsclient argument --parent-id ID can be used to open a
0191e222
CY
68client frame in parent X window ID, via XEmbed. This works like the
69--parent-id argument to Emacs.
70
2a847524
CY
71*** If emacsclient shuts down as a result of Emacs signalling an
72error, its exit status is 1.
73
902a6d8d
SM
74** Completion can cycle, depending on completion-cycle-threshold.
75
2372f278
SM
76** auto-mode-case-fold is now enabled by default.

78+++
79** Emacs now supports display and editing of bidirectional text.
f4b6ba46
EZ
80
81See the node "Bidirectional Editing" in the Emacs Manual for some
82initial documentation.
83
84To 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.
86
87The buffer-local variable `bidi-paragraph-direction', if non-nil,
88forces each paragraph in the buffer to have its base direction
89according to the value of this variable. Possible values are
90`right-to-left' and `left-to-right'. If the value is nil (the
91default), Emacs determines the base direction of each paragraph from
92its text, as specified by the Unicode Bidirectional Algorithm.
93
d20e1419
EZ
94The function `current-bidi-paragraph-direction' returns the actual
95value of paragraph base direction at point.
96
f4b6ba46
EZ
97Reordering of bidirectional text for display in Emacs is a "Full
98bidirectionality" class implementation of the Unicode Bidirectional
99Algorithm.
100
46759717
EZ
101Note that some advanced display features, such as overlay strings and
102`display' text properties, do not yet work correctly when
103bidirectional text is reordered for display.
104
303500aa 105** GTK scroll-bars are now placed on the right by default.
52834b6b
CY
106Use `set-scroll-bar-mode' to change this.
107
20fe03ad 108** GTK tool bars can have just text, just images or images and text.
d8004abe 109Customize `tool-bar-style' to choose style. On a Gnome desktop, the default
20fe03ad
JD
110is taken from the desktop settings.
111
8b2dd508
JD
112** GTK tool bars can be placed on the left/right or top/bottom of the frame.
113The frame-parameter tool-bar-position controls this. It takes the values
1c0d77cc 114top, left, right or bottom. The Options => Show/Hide menu has entries
8b2dd508
JD
115for this.
116
8740c12d 117** ImageMagick support.
b2fa3a09
GM
118It is now possible to use the ImageMagick library to load many new
119image formats in Emacs. By default, Emacs links with the ImageMagick
120libraries if they are present at build time. To disable this, use
8ea189f7 121the configure option `--without-imagemagick'.
16a91140 122
8740c12d
GM
123The new function `imagemagick-types' returns a list of image file
124extensions that your installation of ImageMagick supports. The
125function `imagemagick-register-types' enables ImageMagick support for
b2957ea8 126these image types, minus those listed in `imagemagick-types-inhibit'.
16a91140 127
8740c12d 128See the Emacs Lisp Reference Manual for more information.
16a91140 129
3a46642b
J
130** The colors for selected text (the region face) are taken from the GTK
131theme when Emacs is built with GTK.
132
aa1859f5
J
133** Emacs uses GTK tooltips by default if built with GTK. You can turn that
134off by customizing x-gtk-use-system-tooltips.
135
1ecb2d3f 136** Lucid menus and dialogs can display antialiased fonts if Emacs is built
a6ac7fc4
JD
137with Xft. To change font, use X resource faceName, for example:
138Emacs.pane.menubar.faceName: Courier-12
139Set faceName to none and use font to use the old X fonts.
99852628 140
0eb025fb
EZ
141+++
142** Enhanced support for characters that have no glyphs in available fonts
143If a character has no glyphs in any of the available fonts, Emacs by
144default will display it either as a hexadecimal code in a box or as a
145thin 1-pixel space. In addition to these two methods, Emacs can
146display these characters as empty box, as an acronym, or not display
147them at all. To change how these characters are displayed, customize
148the variable `glyphless-char-display-control'.
149
150On character terminals these methods are used for characters that
151cannot be encoded by the `terminal-coding-system'.
152
917794d5
CY
153** On graphical displays, the mode-line no longer ends in dashes.
154
b7d65a5f
GM
155** Basic SELinux support has been added.
156This requires Emacs to be linked with libselinux at build time.
157
d8004abe
GM
158*** Emacs preserves the SELinux file context when backing up, and
159optionally when copying files. To this end, copy-file has an extra
160optional argument, and backup-buffer and friends include the SELinux
161context in their return values.
b7d65a5f
GM
162
163*** The new functions file-selinux-context and set-file-selinux-context
164get and set the SELinux context of a file.
165
a5bee597
MA
166*** Tramp offers handlers for file-selinux-context and set-file-selinux-context
167for remote machines which support SELinux.
168
9c524fcb 169** The function kill-emacs is now run upon receipt of the signals SIGTERM
383ebd15 170and SIGHUP, and upon SIGINT in batch mode.
9c524fcb
GM
171
172** kill-emacs-hook is now also run in batch mode.
173
79ce172a 174** New scrolling commands `scroll-up-command' and `scroll-down-command'
7b05466f
JL
175(bound to C-v/[next] and M-v/[prior]) does not signal errors at top/bottom
176of buffer at first key-press (instead moves to top/bottom of buffer)
177when a new variable `scroll-error-top-bottom' is non-nil.
79ce172a 178
5a97d2da
JL
179** New scrolling commands `scroll-up-line' and `scroll-down-line'
180scroll a line instead of full screen.
181
a4b000fb 182** New property `scroll-command' should be set on a command's symbol to
b2957ea8 183define it as a scroll command affected by `scroll-preserve-screen-position'.
9013a7f8 184
f1a5d776
CY
185** Trash changes
186
187*** `delete-by-moving-to-trash' now only affects commands that specify
188trashing. This avoids inadvertently trashing temporary files.
189
190*** Calling `delete-file' or `delete-directory' with a prefix argument
191now forces true deletion, regardless of `delete-by-moving-to-trash'.
192
f0bf7c8e
JL
193** New option `list-colors-sort' defines the color sort order
194for `list-colors-display'.
195
44198b6e
CY
196** An Emacs Lisp package manager is now included.
197This is a convenient way to download and install additional packages,
42d9cffa 198from a package repository at elpa.gnu.org.
cb6c4991
CY
199
200*** `M-x list-packages' shows a list of packages, which can be
201selected for installation.
202
203*** New command `describe-package', bound to `C-h P'.
44198b6e
CY
204
205*** By default, all installed packages are loaded and activated
206automatically when Emacs starts up. To disable this, set
207`package-enable-at-startup' to nil. To change which packages are
208loaded, customize `package-load-list'.
209
f065864f
CY
210** Custom Themes
211
212*** `M-x customize-themes' lists Custom themes which can be enabled.
213
782b5e8d
CY
214*** New option `custom-theme-load-path' is the load path for themes.
215Emacs no longer looks for custom themes in `load-path'. The default
216is to search in `custom-theme-directory', followed by a built-in theme
217directory named "themes/" in `data-directory'.
218
4ddf410a
MA
219** The user option `remote-file-name-inhibit-cache' controls whether
220the remote file-name cache is used for read access.
221
17284e30
GM
222** The standalone programs lib-src/digest-doc and sorted-doc have been
223replaced with Lisp commands `doc-file-to-man' and `doc-file-to-info'.

eb199145 226* Editing Changes in Emacs 24.1
b350bdf2 227
ea4f7750
GM
228+++
229** There is a new command `count-words-region', which does what you expect.
230
a982c7ec
CY
231** completion-at-point is now an alias for complete-symbol.
232
d74cba8f
MA
233** The default value of `backup-by-copying-when-mismatch' is now t.
234
b9229673
CY
235** Deletion changes
236
237*** New option `delete-active-region'.
238If non-nil, C-d, [delete], and DEL delete the region if it is active
239and no prefix argument is given. If set to `kill', these commands
240kill instead.
241
242*** New command `delete-forward-char', bound to C-d and [delete].
42d9cffa
CY
243This is meant for interactive use, and obeys `delete-active-region'.
244The command `delete-char' does not obey `delete-active-region'.
b9229673
CY
245
246*** `delete-backward-char' is now a Lisp function.
247Apart from obeying `delete-active-region', its behavior is unchanged.
248However, the byte compiler now warns if it is called from Lisp; you
249should use delete-char with a negative argument instead.
250
251*** The option `mouse-region-delete-keys' has been deleted.
252
f9d71b42
CY
253** Selection changes.
254
7c23dd44 255The default handling of clipboard and primary selections has been
42d9cffa
CY
256changed to conform with other X applications. The exact changes are
257described below; in short, mouse commands to select and paste text now
258use the primary selection, while all other commands for killing and
259yanking text now use the clipboard.
7c23dd44 260
42d9cffa
CY
261*** Merely selecting text (e.g. with drag-mouse-1) does not add it to
262the kill-ring. On systems with a primary selection separate from the
263clipboard (such as X), the selected text is put in the primary
264selection.
265
266*** mouse-2 is now bound to `mouse-yank-primary', which pastes from
267the primary selection regardless of the contents of the kill-ring.
268
269*** Commands that kill text or copy it to the kill-ring (M-w, C-w,
270C-k, etc.) also put the killed text into the clipboard. This change
271also means that the "Copy", "Cut", and "Paste" items in the "Edit"
272menu are now exactly equivalent to, respectively M-w, C-w, and C-y.
273
274*** Yank commands, such as C-y and M-y, retrieve text from the
275clipboard if it is available.
276
277*** The above changes are reflected in the following new defaults:
278
279**** `select-active-regions' now defaults to t.
d1b08c88 280It also accepts a new value, `only', which means to only set the
7c23dd44
CY
281primary selection for temporarily active regions (usually made by
282mouse-dragging or shift-selection).
283
42d9cffa 284**** `mouse-2' is now bound to `mouse-yank-primary'.
7c9b11be 285Previously, it was bound to `mouse-yank-at-click' (which is now
4c0f50c9 286unbound by default).
f9d71b42 287
42d9cffa
CY
288**** `x-select-enable-clipboard' now defaults to t on all platforms.
289Note that this variable was already non-nil by default on MS-Windows,
290which does not support the primary selection between applications.
f9d71b42 291
42d9cffa 292**** `x-select-enable-primary' now defaults to nil.
7c9b11be
EZ
293This variable exists only on X; its default value was t in previous
294versions.
2490cbbc 295
42d9cffa
CY
296**** `mouse-drag-copy-region' now defaults to nil.
297
298*** To return to the previous behavior, where mouse commands use the
299clipboard, 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
301text into the clipboard, only to the primary selection, additionally
302set `x-select-enable-clipboard' to nil.
f9d71b42 303
084e6df3
JD
304*** Support for X cut buffers has been removed.
305

eb199145 307* Changes in Specialized Modes and Packages in Emacs 24.1
efeb796b 308
78835dd0
SM
309** shell-mode can track your cwd by reading it from your prompt.
310Just set shell-dir-cookie-re to an appropriate regexp.
311
cbf83ce9
SM
312** Modula-2 mode provides auto-indentation.
313
b879a6e2
SM
314** latex-electric-env-pair-mode keeps \begin..\end matched on the fly.
315
360ac530 316** FIXME: xdg-open for browse-url and reportbug, 2010/08.
0ac3effe 317
b3671a51
JL
318** Archive Mode has basic support to browse 7z archives.
319
8a8d54cd
VD
320** ERC changes
321
322*** New vars `erc-autojoin-timing' and `erc-autojoin-delay'.
323If the value of `erc-autojoin-timing' is 'ident, ERC autojoins after a
324successful NickServ identification, or after `erc-autojoin-delay'
325seconds. The default value, 'ident, means to autojoin immediately
326after connecting.
327
5c0c0f77
LMI
328*** New variable `erc-coding-system-precedence': If we use `undecided'
329as the server coding system, this variable will then be consulted.
330The default is to decode strings that can be decoded as utf-8 as
331utf-8, and do the normal `undecided' decoding for the rest.
332
27d3cd56
CY
333** In ido-mode, C-v is no longer bound to ido-toggle-vc.
334The reason is that this interferes with cua-mode.
335
c1e25821 336** partial-completion-mode is now obsolete.
79ccd68f
SM
337You can get a comparable behavior with:
338(setq completion-styles '(partial-completion initials))
339(setq completion-pcm-complete-word-inserts-delimiters t)
c1e25821 340
18c812bd 341** mpc.el: Can use pseudo tags of the form tag1|tag2 as a union of two tags.
b2957ea8 342
1d83b0e9
GM
343** server can listen on a specific port using the server-port option.
344
cf16af42
GM
345** Calendar, Diary, and Appt
346
347---
348*** The obsolete (since Emacs 22.1) method of enabling the appt package
349by adding appt-make-list to diary-hook has been removed. Use appt-activate.
350
351---
352*** Some appt variables (obsolete since Emacs 22.1) have been removed:
353appt-issue-message (use the function appt-activate)
354appt-visible/appt-msg-window (use the variable appt-display-format)
355
356---
357*** Some diary function aliases (obsolete since Emacs 22.1) have been removed:
358view-diary-entries, list-diary-entries, show-all-diary-entries
359
52834b6b
CY
360** Customize
361
362*** Customize buffers now contain a search field.
363The search is performed using `customize-apropos'.
42d9cffa 364To turn off the search field, set custom-search-field to nil.
52834b6b
CY
365
366*** Custom options now start out hidden if at their default values.
367Use the arrow to the left of the option name to toggle visibility.
368
369*** custom-buffer-sort-alphabetically now defaults to t.
370
371*** The color widget now has a "Choose" button, which allows you to
372choose a color via list-colors-display.
373
f5d6548a
JL
374** Dired-x
375
376*** dired-jump and dired-jump-other-window called with a prefix argument
377read a file name from the minibuffer instead of using buffer-file-name.
378
8117868f
DN
379** Directory local variables can apply to file-less buffers.
380For example, adding "(diff-mode . ((mode . whitespace)))" to your
d8004abe 381.dir-locals.el file, will turn on `whitespace-mode' for *vc-diff* buffers.
8117868f 382
7492acc9
MM
383** SQL Mode enhancements.
384
30c4d8dc
MM
385*** Several variables have been marked as safe local variables. The
386variables `sql-product', `sql-user', `sql-server', `sql-database' and
387`sql-port' can now be safely used as local variables.
7492acc9 388
9250002f
MM
389*** `sql-dialect' is a synonym for `sql-product'.
390
74790210 391*** Added ability to login with a port on MySQL and Postgres.
7492acc9 392The custom variable `sql-port' can be specified for connection to
74790210
MM
393MySQL or Postgres servers. By default, the port is not listed in
394either login parameter, but will be added to the command line if set
395to a non-zero value.
7492acc9 396
9250002f
MM
397*** Dynamic selection of product in an SQL interactive session.
398If you use `sql-product-interactive' to start an SQL interactive
399session it uses the current value of `sql-product'. Preceding the
400invocation with C-u will force it to ask for the product before
401creating the session.
402
403*** Renaming a SQL interactive buffer when it is created.
404Prefixing the SQL interactive commands (`sql-sqlite', `sql-postgres',
405`sql-mysql', etc.) with C-u will force a new interactive session to be
406started and will prompt for the new name. This will reduce the need
407for `sql-rename-buffer' is most common use cases.
408
3bd2cfef
MM
409*** Command continuation prompts in SQL interactive mode are suppressed.
410Multiple line commands in SQL interactive mode, generate command
411continuation prompts which needlessly confuse the output. These
412prompts are now filtered out from the output. This change impacts
413multiple line SQL statements entered with C-j between each line,
414statements yanked into the buffer and statements sent with
415`sql-send-*' functions.
416
7492acc9
MM
417*** Custom variables control prompting for login parameters.
418Each supported product has a custom variable `sql-*-login-params'
419which is a list of the parameters to be prompted for before a
420connection is established.
421
74790210
MM
422The lists consist of the following five tokens: `user', `password',
423`database', `server', and `port'. The order in which they appear is
424the order in which they are prompted. The tokens symbols can be
425replaced by a sublist starting with the token and followed by a plist
426which control the prompting for values. The tokens `user',
427`database', and `server' each can take a property of :default which
428specifies the value to be used if no value is entered. The
429`database', `server', and `port' tokens handle the :completion
430property which restricts the entry to either one of the values in the
431list or to one of the values returned by the function provided as the
432property value. The `database' and `server' tokens also accept the
433:file property whose value is a regexp to identify useful file names.
434
435 (user :default DEF)
436 (database :default DEF
437 :file FILEPAT
438 :completion COMPLETE)
439 (server :default DEF
440 :file FILEPAT
441 :completion COMPLETE)
442
443The FILEPAT when :file is specified is a regexp that will match valid
444file names (without the directory portion). Generally these strings
445will be of the form ".+\.SUF" where SUF is the desired file suffix.
446
447When :completion is specified, the COMPLETE corresponds to the
448PREDICATE argument to the `completing-read' function (a list of
449possible values or a function returning such a list).
5474c40f 450
30c4d8dc
MM
451*** Added `sql-connection-alist' to record login parameter values.
452An alist for recording different username, database and server
453values. If there are multiple databases that you connect to the
454parameters needed can be stored in this alist.
455
456For example, the following might be set in the user's init.el:
457
458 (setq sql-connection-alist
459 '((dev (sql-product 'sqlite)
460 (sql-database "/home/mmaug/dev.db"))
461 (prd (sql-product 'oracle)
462 (sql-user "mmaug")
463 (sql-database "iprd2a"))))
464
465This defines two connections named "dev" and "prd".
466
467*** Added `sql-connect' to use predefined connections.
468Sets the login parameters based on the values in the
469`sql-connection-alist' and start a SQL interactive session. Any
470values specified in the connection will not be prompted for.
471
472In the example above, if the user were to invoke M-x sql-connect, they
473would be prompted for the connection. The user can respond with
474either "dev" or "prd". The "dev" connection would connect to the
475SQLite database without prompting; the "prd" connection would prompt
476for the users password and then connect to the Oracle database.
477
d26b0ea9 478**** Added SQL->Start... submenu when connections are defined.
b2957ea8 479When connections have been defined, there is a submenu available that
d26b0ea9
MM
480allows the user to select one to start a SQLi session. The "Start
481SQLi Session" item moves to the "Start..." submenu when cnnections
482have been defined.
483
484**** Added "Save Connection" menu item in SQLi buffers.
485When a SQLi session is not started by a connection then
486`sql-save-connection' will gather the login params specified for the
487session and save them as a new connection.
488
74790210
MM
489*** List database objects and details.
490Once a SQL interactive session has been started, you can get a list of
491the objects in the database and see details of those objects. The
492objects shown and the details available are product specific.
493
494**** List all objects.
495Using `M-x sql-list-all', `C-c C-l a' or selecting "SQL->List all
496objects" will list all the objects in the database. At a minimum it
497lists the tables and views in the database. Preceeding the command by
498universal argument may provide additional details or extend the
499listing to include other schemas objects. The list will appear in a
500separate window in view-mode.
501
502**** List Table details.
503Using `M-x sql-list-table', `C-c C-l t' or selecting "SQL->List Table
504details" will ask for the name of a database table or view and display
505the list of columns in the relation. Preceeding the comand with the
506universal argument may provide additional details about each column.
507The list will appear in a separate window in view-mode.
508
7492acc9
MM
509*** Added option `sql-send-terminator'.
510When set makes sure that each command sent with `sql-send-*' commands
511are properly terminated and submitted to the SQL processor.
512
513*** Added option `sql-oracle-scan-on'.
514When set commands sent to Oracle's SQL*Plus are scanned for strings
30c4d8dc
MM
515starting with an ampersand and the user is asked for replacement text.
516In general, the SQL*Plus option SCAN should always be set OFF under
517SQL interactive mode and this option used in its place.
7492acc9
MM
518
519*** SQL interactive mode will replace tabs with spaces.
520This prevents the comand interpretter for MySQL and Postgres from
521listing object name completions when being sent text via
522`sql-send-*' functions.
523
524*** An API for manipulating SQL product definitions has been added.
525

526** s-region.el is now declared obsolete, superceded by shift-select-mode
527enabled by default in 23.1.

CY
545** VC and related modes
546
547*** Support for pulling on distributed version control systems.
548The vc-update command now runs a "pull" operation, if it is supported.
549This updates the current branch from upstream. A prefix argument
550means to prompt the user for command specifics, e.g. a pull location.
551
552**** vc-pull is an alias for vc-update.
553
554**** Currently supported by Bzr.
555
556*** Support for merging on distributed version control systems.
557The vc-merge command now runs a "merge" operation, if it is supported.
558This merges another branch into the current one. A prefix argument
559means to prompt the user for command specifics, e.g. a merge location.
560
561**** Currently supported by Bzr.

CY
583** For mouse click input events in the text area, the Y pixel
584coordinate in the POSITION list now counts from the top of the text
585area, excluding any header line. Previously, it counted from the top
586of the header line.

596** Passing a nil argument to a minor mode function now turns the mode
597 ON unconditionally.

598
599** During startup, Emacs no longer adds entries for `menu-bar-lines'
600and `tool-bar-lines' to `default-frame-alist' and
601`initial-frame-alist'. With these alist entries omitted, `make-frame'
602checks the value of the variable `menu-bar-mode'/`tool-bar-mode' to
603determine whether to create a menu-bar or tool-bar, respectively.
604If the alist entries are added, they override the value of
605`menu-bar-mode'/`tool-bar-mode'.
606

607** Regions created by mouse dragging are now normal active regions,
608similar to the ones created by shift-selection. In previous Emacs
609versions, these regions were delineated by `mouse-drag-overlay', which

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

659** define-minor-mode accepts a new keyword :variable.
660
b2957ea8 661** `delete-file' and `delete-directory' now accept optional arg TRASH.
f1a5d776
CY
662Trashing is performed if TRASH and `delete-by-moving-to-trash' are
663both non-nil. Interactively, TRASH defaults to t, unless a prefix
664argument is supplied (see Trash changes, above).

668** New completion style `substring'.
669
9317e499
CY
670** `facemenu-read-color' is now an alias for `read-color'.
671The command `read-color' now requires a match for a color name or RGB
672triplet, instead of signalling an error if the user provides a invalid
673input.

676** Image API
677
678*** When the image type is one of listed in `image-animated-types'
1546c559 679and the number of sub-images in the image is more than one, then the
00fe2df1
JL
680new function `create-animated-image' creates an animated image where
681sub-images are displayed successively with the duration defined by
682`image-animate-max-time' and the delay between sub-images defined
683by the Graphic Control Extension of the image.

687** XML and HTML parsing
688
689*** If Emacs is compiled with libxml2 support (which is the default),
4b9832a6
CY
690two new Emacs Lisp-level functions are defined:
691`xml-parse-html-string-internal' (which will parse "real world" HTML)
692and `xml-parse-string-internal' (which parses XML). Both return an
693Emacs Lisp parse tree.
694
695FIXME: These should be front-ended by xml.el.

9326ba26
CY
703** Progress reporters can now "spin".
704The MIN-VALUE and MAX-VALUE arguments of `make-progress-reporter' can
705now be nil, or omitted. This makes a "non-numeric" reporter. Each
706time you call `progress-reporter-update' on that progress reporter,
707with a nil or omitted VALUE argument, the reporter message is
708displayed with a "spinning bar".
