eb199145 25* Installation Changes in Emacs 24.1
09e18d03 26
338648ad
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
JD
140** Lucid menus and dialogs can display antialiased fonts if Emacs is built
141with Xft.
99852628 142
917794d5
CY
143** On graphical displays, the mode-line no longer ends in dashes.
144
b7d65a5f
GM
145** Basic SELinux support has been added.
146This requires Emacs to be linked with libselinux at build time.
147
d8004abe
GM
148*** Emacs preserves the SELinux file context when backing up, and
149optionally when copying files. To this end, copy-file has an extra
150optional argument, and backup-buffer and friends include the SELinux
151context in their return values.
b7d65a5f
GM
152
153*** The new functions file-selinux-context and set-file-selinux-context
154get and set the SELinux context of a file.
155
a5bee597
MA
156*** Tramp offers handlers for file-selinux-context and set-file-selinux-context
157for remote machines which support SELinux.
158
9c524fcb 159** The function kill-emacs is now run upon receipt of the signals SIGTERM
383ebd15 160and SIGHUP, and upon SIGINT in batch mode.
9c524fcb
GM
161
162** kill-emacs-hook is now also run in batch mode.
163
79ce172a 164** New scrolling commands `scroll-up-command' and `scroll-down-command'
7b05466f
JL
165(bound to C-v/[next] and M-v/[prior]) does not signal errors at top/bottom
166of buffer at first key-press (instead moves to top/bottom of buffer)
167when a new variable `scroll-error-top-bottom' is non-nil.
79ce172a 168
5a97d2da
JL
169** New scrolling commands `scroll-up-line' and `scroll-down-line'
170scroll a line instead of full screen.
171
a4b000fb 172** New property `scroll-command' should be set on a command's symbol to
b2957ea8 173define it as a scroll command affected by `scroll-preserve-screen-position'.
9013a7f8 174
f1a5d776
CY
175** Trash changes
176
177*** `delete-by-moving-to-trash' now only affects commands that specify
178trashing. This avoids inadvertently trashing temporary files.
179
180*** Calling `delete-file' or `delete-directory' with a prefix argument
181now forces true deletion, regardless of `delete-by-moving-to-trash'.
182
f0bf7c8e
JL
183** New option `list-colors-sort' defines the color sort order
184for `list-colors-display'.
185
44198b6e
CY
186** An Emacs Lisp package manager is now included.
187This is a convenient way to download and install additional packages,
cb6c4991
CY
188from elpa.gnu.org.
189
190*** `M-x list-packages' shows a list of packages, which can be
191selected for installation.
192
193*** New command `describe-package', bound to `C-h P'.
44198b6e
CY
194
195*** By default, all installed packages are loaded and activated
196automatically when Emacs starts up. To disable this, set
197`package-enable-at-startup' to nil. To change which packages are
198loaded, customize `package-load-list'.
199
f065864f
CY
200** Custom Themes
201
202*** `M-x customize-themes' lists Custom themes which can be enabled.
203
782b5e8d
CY
204*** New option `custom-theme-load-path' is the load path for themes.
205Emacs no longer looks for custom themes in `load-path'. The default
206is to search in `custom-theme-directory', followed by a built-in theme
207directory named "themes/" in `data-directory'.
208
4ddf410a
MA
209** The user option `remote-file-name-inhibit-cache' controls whether
210the remote file-name cache is used for read access.
211
0bfd685e 212\f
eb199145 213* Editing Changes in Emacs 24.1
b350bdf2 214
a982c7ec
CY
215** completion-at-point is now an alias for complete-symbol.
216
b9229673
CY
217** Deletion changes
218
219*** New option `delete-active-region'.
220If non-nil, C-d, [delete], and DEL delete the region if it is active
221and no prefix argument is given. If set to `kill', these commands
222kill instead.
223
224*** New command `delete-forward-char', bound to C-d and [delete].
225This is meant for interactive use, and obeys `delete-active-region';
226delete-char, meant for Lisp, does not obey `delete-active-region'.
227
228*** `delete-backward-char' is now a Lisp function.
229Apart from obeying `delete-active-region', its behavior is unchanged.
230However, the byte compiler now warns if it is called from Lisp; you
231should use delete-char with a negative argument instead.
232
233*** The option `mouse-region-delete-keys' has been deleted.
234
f9d71b42
CY
235** Selection changes.
236
7c23dd44
CY
237The default handling of clipboard and primary selections has been
238changed to conform with other X applications.
f9d71b42 239
4c0f50c9
EZ
240The new behavior is that by default Emacs does not put selected text
241into the clipboard, and does not add it to kill-ring, merely because
242the text was selected. Only commands that kill text or copy it to the
7c9b11be
EZ
243kill-ring (C-w, M-w, C-k, etc.) put the killed text into the
244clipboard. Selected text is put into the primary selection (on
245systems, such as X, that support the primary selection separately from
246the clipboard).
247
248Similarly, Emacs by default does not retrieve text from the clipboard
249when the mouse (e.g., mouse-2) is used for pasting text selected in
4c0f50c9
EZ
250another application. Mouse commands that paste text retrieve text
251from the primary selection, on systems that support it separately from
252the clipboard. Text from the clipboard is retrieved only by C-y, M-y
253and other commands that yank text from the kill-ring.
7c9b11be
EZ
254
255In other words, the default behavior is that mouse gestures that
4c0f50c9
EZ
256select and paste text work with the primary selection (on X), while
257keyboard commands that kill/copy and paste text work with the
258clipboard.
7c9b11be
EZ
259
260This change also means that the "Copy", "Cut", and "Paste" items of
261the menu-bar "Edit" menu are now exactly equivalent to, respectively
262M-w, C-w, and C-y.
263
264To get back the previous behavior, whereby mouse gestures set the
265clipboard and retrieve text from there, customize the variables
4c0f50c9
EZ
266`mouse-drag-copy-region' and (on X only) `x-select-enable-primary' to
267non-nil values. If you don't want Emacs to put the text into the
268clipboard, only to the primary selection, additionally customize
7c9b11be
EZ
269`x-select-enable-clipboard' to nil.
270
271These changes in the default behavior are reflected in the default
272values of several variables:
273
7c23dd44 274*** `select-active-regions' now defaults to t, so active regions set
7c9b11be 275the primary selection. It was nil in previous versions.
7c23dd44 276
d1b08c88 277It also accepts a new value, `only', which means to only set the
7c23dd44
CY
278primary selection for temporarily active regions (usually made by
279mouse-dragging or shift-selection).
280
281*** `mouse-2' is now bound to `mouse-yank-primary'.
7c9b11be 282Previously, it was bound to `mouse-yank-at-click' (which is now
4c0f50c9 283unbound by default).
f9d71b42 284
7c9b11be 285*** `x-select-enable-clipboard' now defaults to t on all platforms.
7c23dd44 286Thus, killing and yanking now use the clipboard (in addition to the
7c9b11be
EZ
287kill ring). Note that this variable was already non-nil by default on
288MS-Windows, which does not support the primary selection between
289applications.
f9d71b42 290
2490cbbc 291*** `x-select-enable-primary' now defaults to nil.
7c9b11be
EZ
292This variable exists only on X; its default value was t in previous
293versions.
2490cbbc 294
f9d71b42 295*** `mouse-drag-copy-region' now defaults to nil.
7c9b11be 296Its previous default value was t.
f9d71b42 297
084e6df3
JD
298*** Support for X cut buffers has been removed.
299

eb199145 301* Changes in Specialized Modes and Packages in Emacs 24.1
efeb796b 302
b879a6e2
SM
303** latex-electric-env-pair-mode keeps \begin..\end matched on the fly.
304
360ac530 305** FIXME: xdg-open for browse-url and reportbug, 2010/08.
0ac3effe 306
b3671a51
JL
307** Archive Mode has basic support to browse 7z archives.
308
8a8d54cd
VD
309** ERC changes
310
311*** New vars `erc-autojoin-timing' and `erc-autojoin-delay'.
312If the value of `erc-autojoin-timing' is 'ident, ERC autojoins after a
313successful NickServ identification, or after `erc-autojoin-delay'
314seconds. The default value, 'ident, means to autojoin immediately
315after connecting.
316
27d3cd56
CY
317** In ido-mode, C-v is no longer bound to ido-toggle-vc.
318The reason is that this interferes with cua-mode.
319
c1e25821 320** partial-completion-mode is now obsolete.
79ccd68f
SM
321You can get a comparable behavior with:
322(setq completion-styles '(partial-completion initials))
323(setq completion-pcm-complete-word-inserts-delimiters t)
c1e25821 324
18c812bd 325** mpc.el: Can use pseudo tags of the form tag1|tag2 as a union of two tags.
b2957ea8 326
cf16af42
GM
327** Calendar, Diary, and Appt
328
329---
330*** The obsolete (since Emacs 22.1) method of enabling the appt package
331by adding appt-make-list to diary-hook has been removed. Use appt-activate.
332
333---
334*** Some appt variables (obsolete since Emacs 22.1) have been removed:
335appt-issue-message (use the function appt-activate)
336appt-visible/appt-msg-window (use the variable appt-display-format)
337
338---
339*** Some diary function aliases (obsolete since Emacs 22.1) have been removed:
340view-diary-entries, list-diary-entries, show-all-diary-entries
341
52834b6b
CY
342** Customize
343
344*** Customize buffers now contain a search field.
345The search is performed using `customize-apropos'.
346To turn off the search field, set custom-search-field to nil .
347
348*** Custom options now start out hidden if at their default values.
349Use the arrow to the left of the option name to toggle visibility.
350
351*** custom-buffer-sort-alphabetically now defaults to t.
352
353*** The color widget now has a "Choose" button, which allows you to
354choose a color via list-colors-display.
355
f5d6548a
JL
356** Dired-x
357
358*** dired-jump and dired-jump-other-window called with a prefix argument
359read a file name from the minibuffer instead of using buffer-file-name.
360
855a2294
DN
361** VC and related modes
362
e97a42c1 363*** New VC commands: vc-log-incoming, vc-log-outgoing, vc-find-conflicted-file.
31527c56 364
6941ffec
DN
365**** vc-log-incoming for Git runs "git fetch" so that the necessary
366data is available locally.
367
eccdfe5f
DN
368**** vc-log-incoming and vc-log-outgoing for Git require version 1.7 (or newer).
369
54d3626e
DN
370*** New key bindings: C-x v I and C-x v O bound to vc-log-incoming and
371vc-log-outgoing, respectively.
372
1fbcf428
DN
373*** The 'g' key in VC diff, log, log-incoming and log-outgoing buffers
374reruns the corresponding VC command to compute an up to date version
375of the buffer.
376
855a2294
DN
377*** vc-dir for Bzr supports viewing shelve contents and shelving snapshots.
378
09158997 379*** Special markup can be added to log-edit buffers.
e97a42c1
SM
380The log-edit buffers are expected to have a format similar to email messages
381with headers of the form:
382 Author: <author of this change>
383 Summary: <one line summary of this change>
384 Fixes: <reference to the bug fixed by this change>
385Some backends handle some of those headers specially, but any unknown header
386is just left as is in the message, so it is not lost.
09158997 387
fab43c76
DN
388**** vc-git handles Author: and Date:
389**** vc-hg handles Author: and Date:
390**** vc-bzr handles Author:, Date: and Fixes:
391**** vc-mtn handles Author: and Date:
392
b3d42406
DN
393*** Pressing g in a *vc-diff* buffer reruns vc-diff, so it will
394produce an up to date diff.
395
8117868f
DN
396** Directory local variables can apply to file-less buffers.
397For example, adding "(diff-mode . ((mode . whitespace)))" to your
d8004abe 398.dir-locals.el file, will turn on `whitespace-mode' for *vc-diff* buffers.
8117868f 399
7492acc9
MM
400** SQL Mode enhancements.
401
30c4d8dc
MM
402*** Several variables have been marked as safe local variables. The
403variables `sql-product', `sql-user', `sql-server', `sql-database' and
404`sql-port' can now be safely used as local variables.
7492acc9 405
9250002f
MM
406*** `sql-dialect' is a synonym for `sql-product'.
407
74790210 408*** Added ability to login with a port on MySQL and Postgres.
7492acc9 409The custom variable `sql-port' can be specified for connection to
74790210
MM
410MySQL or Postgres servers. By default, the port is not listed in
411either login parameter, but will be added to the command line if set
412to a non-zero value.
7492acc9 413
9250002f
MM
414*** Dynamic selection of product in an SQL interactive session.
415If you use `sql-product-interactive' to start an SQL interactive
416session it uses the current value of `sql-product'. Preceding the
417invocation with C-u will force it to ask for the product before
418creating the session.
419
420*** Renaming a SQL interactive buffer when it is created.
421Prefixing the SQL interactive commands (`sql-sqlite', `sql-postgres',
422`sql-mysql', etc.) with C-u will force a new interactive session to be
423started and will prompt for the new name. This will reduce the need
424for `sql-rename-buffer' is most common use cases.
425
3bd2cfef
MM
426*** Command continuation prompts in SQL interactive mode are suppressed.
427Multiple line commands in SQL interactive mode, generate command
428continuation prompts which needlessly confuse the output. These
429prompts are now filtered out from the output. This change impacts
430multiple line SQL statements entered with C-j between each line,
431statements yanked into the buffer and statements sent with
432`sql-send-*' functions.

434*** Custom variables control prompting for login parameters.
435Each supported product has a custom variable `sql-*-login-params'
436which is a list of the parameters to be prompted for before a
437connection is established.
438
74790210
MM
439The lists consist of the following five tokens: `user', `password',
440`database', `server', and `port'. The order in which they appear is
441the order in which they are prompted. The tokens symbols can be
442replaced by a sublist starting with the token and followed by a plist
443which control the prompting for values. The tokens `user',
444`database', and `server' each can take a property of :default which
445specifies the value to be used if no value is entered. The
446`database', `server', and `port' tokens handle the :completion
447property which restricts the entry to either one of the values in the
448list or to one of the values returned by the function provided as the
449property value. The `database' and `server' tokens also accept the
450:file property whose value is a regexp to identify useful file names.
451
452 (user :default DEF)
453 (database :default DEF
454 :file FILEPAT
455 :completion COMPLETE)
456 (server :default DEF
457 :file FILEPAT
458 :completion COMPLETE)
459
460The FILEPAT when :file is specified is a regexp that will match valid
461file names (without the directory portion). Generally these strings
462will be of the form ".+\.SUF" where SUF is the desired file suffix.
463
464When :completion is specified, the COMPLETE corresponds to the
465PREDICATE argument to the `completing-read' function (a list of
466possible values or a function returning such a list).
5474c40f 467
30c4d8dc
MM
468*** Added `sql-connection-alist' to record login parameter values.
469An alist for recording different username, database and server
470values. If there are multiple databases that you connect to the
471parameters needed can be stored in this alist.
472
473For example, the following might be set in the user's init.el:
474
475 (setq sql-connection-alist
476 '((dev (sql-product 'sqlite)
477 (sql-database "/home/mmaug/dev.db"))
478 (prd (sql-product 'oracle)
479 (sql-user "mmaug")
480 (sql-database "iprd2a"))))
481
482This defines two connections named "dev" and "prd".
483
484*** Added `sql-connect' to use predefined connections.
485Sets the login parameters based on the values in the
486`sql-connection-alist' and start a SQL interactive session. Any
487values specified in the connection will not be prompted for.
488
489In the example above, if the user were to invoke M-x sql-connect, they
490would be prompted for the connection. The user can respond with
491either "dev" or "prd". The "dev" connection would connect to the
492SQLite database without prompting; the "prd" connection would prompt
493for the users password and then connect to the Oracle database.
494
d26b0ea9 495**** Added SQL->Start... submenu when connections are defined.
b2957ea8 496When connections have been defined, there is a submenu available that
d26b0ea9
MM
497allows the user to select one to start a SQLi session. The "Start
498SQLi Session" item moves to the "Start..." submenu when cnnections
499have been defined.
500
501**** Added "Save Connection" menu item in SQLi buffers.
502When a SQLi session is not started by a connection then
503`sql-save-connection' will gather the login params specified for the
504session and save them as a new connection.
505
74790210
MM
506*** List database objects and details.
507Once a SQL interactive session has been started, you can get a list of
508the objects in the database and see details of those objects. The
509objects shown and the details available are product specific.
510
511**** List all objects.
512Using `M-x sql-list-all', `C-c C-l a' or selecting "SQL->List all
513objects" will list all the objects in the database. At a minimum it
514lists the tables and views in the database. Preceeding the command by
515universal argument may provide additional details or extend the
516listing to include other schemas objects. The list will appear in a
517separate window in view-mode.
518
519**** List Table details.
520Using `M-x sql-list-table', `C-c C-l t' or selecting "SQL->List Table
521details" will ask for the name of a database table or view and display
522the list of columns in the relation. Preceeding the comand with the
523universal argument may provide additional details about each column.
524The list will appear in a separate window in view-mode.
525
7492acc9
MM
526*** Added option `sql-send-terminator'.
527When set makes sure that each command sent with `sql-send-*' commands
528are properly terminated and submitted to the SQL processor.
529
530*** Added option `sql-oracle-scan-on'.
531When set commands sent to Oracle's SQL*Plus are scanned for strings
30c4d8dc
MM
532starting with an ampersand and the user is asked for replacement text.
533In general, the SQL*Plus option SCAN should always be set OFF under
534SQL interactive mode and this option used in its place.
7492acc9
MM
535
536*** SQL interactive mode will replace tabs with spaces.
537This prevents the comand interpretter for MySQL and Postgres from
538listing object name completions when being sent text via
539`sql-send-*' functions.
540
541*** An API for manipulating SQL product definitions has been added.
542
5e418f17
JL
543** s-region.el is now declared obsolete, superceded by shift-select-mode
544enabled by default in 23.1.

546** gdb-mi
547
548*** GDB User Interface migrated to GDB Machine Interface and now
549supports multithread non-stop debugging and debugging of several
550threads simultaneously.

591
592** During startup, Emacs no longer adds entries for `menu-bar-lines'
593and `tool-bar-lines' to `default-frame-alist' and
594`initial-frame-alist'. With these alist entries omitted, `make-frame'
595checks the value of the variable `menu-bar-mode'/`tool-bar-mode' to
596determine whether to create a menu-bar or tool-bar, respectively.
597If the alist entries are added, they override the value of
598`menu-bar-mode'/`tool-bar-mode'.

JB
629** `image-library-alist' is renamed to `dynamic-library-alist'.
630The variable is now used to load all kind of supported dynamic libraries,
631not just image libraries. The previous name is still available as an
632obsolete alias.
633
cf38dd42
SM
634** New variable syntax-propertize-function to set syntax-table properties.
635Replaces font-lock-syntactic-keywords which are now obsolete.
636This allows syntax-table properties to be set independently from font-lock:
637just call syntax-propertize to make sure the text is propertized.
638Together with this new variable come a new hook
639syntax-propertize-extend-region-functions, as well as two helper functions:
640syntax-propertize-via-font-lock to reuse old font-lock-syntactic-keywords
641as-is; and syntax-propertize-rules which provides a new way to specify
642syntactic rules.

b2957ea8 652** `delete-file' and `delete-directory' now accept optional arg TRASH.
f1a5d776
CY
653Trashing is performed if TRASH and `delete-by-moving-to-trash' are
654both non-nil. Interactively, TRASH defaults to t, unless a prefix
655argument is supplied (see Trash changes, above).

661** Image API
662
663*** When the image type is one of listed in `image-animated-types'
1546c559 664and the number of sub-images in the image is more than one, then the
00fe2df1
JL
665new function `create-animated-image' creates an animated image where
666sub-images are displayed successively with the duration defined by
667`image-animate-max-time' and the delay between sub-images defined
668by the Graphic Control Extension of the image.
669

672** XML and HTML parsing
673
674*** If Emacs is compiled with libxml2 support (which is the default),
4b9832a6
CY
675two new Emacs Lisp-level functions are defined:
676`xml-parse-html-string-internal' (which will parse "real world" HTML)
677and `xml-parse-string-internal' (which parses XML). Both return an
678Emacs Lisp parse tree.
679
680FIXME: These should be front-ended by xml.el.

9326ba26
CY
688** Progress reporters can now "spin".
689The MIN-VALUE and MAX-VALUE arguments of `make-progress-reporter' can
690now be nil, or omitted. This makes a "non-numeric" reporter. Each
691time you call `progress-reporter-update' on that progress reporter,
692with a nil or omitted VALUE argument, the reporter message is
693displayed with a "spinning bar".
