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.

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
b7d65a5f
GM
143** Basic SELinux support has been added.
144This requires Emacs to be linked with libselinux at build time.
145
d8004abe
GM
146*** Emacs preserves the SELinux file context when backing up, and
147optionally when copying files. To this end, copy-file has an extra
148optional argument, and backup-buffer and friends include the SELinux
149context in their return values.
b7d65a5f
GM
150
151*** The new functions file-selinux-context and set-file-selinux-context
152get and set the SELinux context of a file.
153
a5bee597
MA
154*** Tramp offers handlers for file-selinux-context and set-file-selinux-context
155for remote machines which support SELinux.
156
9c524fcb 157** The function kill-emacs is now run upon receipt of the signals SIGTERM
383ebd15 158and SIGHUP, and upon SIGINT in batch mode.
9c524fcb
GM
159
160** kill-emacs-hook is now also run in batch mode.
161
79ce172a 162** New scrolling commands `scroll-up-command' and `scroll-down-command'
7b05466f
JL
163(bound to C-v/[next] and M-v/[prior]) does not signal errors at top/bottom
164of buffer at first key-press (instead moves to top/bottom of buffer)
165when a new variable `scroll-error-top-bottom' is non-nil.
79ce172a 166
5a97d2da
JL
167** New scrolling commands `scroll-up-line' and `scroll-down-line'
168scroll a line instead of full screen.
169
a4b000fb 170** New property `scroll-command' should be set on a command's symbol to
b2957ea8 171define it as a scroll command affected by `scroll-preserve-screen-position'.
9013a7f8 172
f1a5d776
CY
173** Trash changes
174
175*** `delete-by-moving-to-trash' now only affects commands that specify
176trashing. This avoids inadvertently trashing temporary files.
177
178*** Calling `delete-file' or `delete-directory' with a prefix argument
179now forces true deletion, regardless of `delete-by-moving-to-trash'.
180
f0bf7c8e
JL
181** New option `list-colors-sort' defines the color sort order
182for `list-colors-display'.
183
44198b6e
CY
184** An Emacs Lisp package manager is now included.
185This is a convenient way to download and install additional packages,
cb6c4991
CY
186from elpa.gnu.org.
187
188*** `M-x list-packages' shows a list of packages, which can be
189selected for installation.
190
191*** New command `describe-package', bound to `C-h P'.
44198b6e
CY
192
193*** By default, all installed packages are loaded and activated
194automatically when Emacs starts up. To disable this, set
195`package-enable-at-startup' to nil. To change which packages are
196loaded, customize `package-load-list'.
197
f065864f
CY
198** Custom Themes
199
200*** `M-x customize-themes' lists Custom themes which can be enabled.
201
782b5e8d
CY
202*** New option `custom-theme-load-path' is the load path for themes.
203Emacs no longer looks for custom themes in `load-path'. The default
204is to search in `custom-theme-directory', followed by a built-in theme
205directory named "themes/" in `data-directory'.
206
4ddf410a
MA
207** The user option `remote-file-name-inhibit-cache' controls whether
208the remote file-name cache is used for read access.

eb199145 211* Editing Changes in Emacs 24.1
b350bdf2 212
a982c7ec
CY
213** completion-at-point is now an alias for complete-symbol.
214
b9229673
CY
215** Deletion changes
216
217*** New option `delete-active-region'.
218If non-nil, C-d, [delete], and DEL delete the region if it is active
219and no prefix argument is given. If set to `kill', these commands
220kill instead.
221
222*** New command `delete-forward-char', bound to C-d and [delete].
223This is meant for interactive use, and obeys `delete-active-region';
224delete-char, meant for Lisp, does not obey `delete-active-region'.
225
226*** `delete-backward-char' is now a Lisp function.
227Apart from obeying `delete-active-region', its behavior is unchanged.
228However, the byte compiler now warns if it is called from Lisp; you
229should use delete-char with a negative argument instead.
230
231*** The option `mouse-region-delete-keys' has been deleted.
232
f9d71b42
CY
233** Selection changes.
234
7c23dd44
CY
235The default handling of clipboard and primary selections has been
236changed to conform with other X applications.
f9d71b42 237
4c0f50c9
EZ
238The new behavior is that by default Emacs does not put selected text
239into the clipboard, and does not add it to kill-ring, merely because
240the text was selected. Only commands that kill text or copy it to the
7c9b11be
EZ
241kill-ring (C-w, M-w, C-k, etc.) put the killed text into the
242clipboard. Selected text is put into the primary selection (on
243systems, such as X, that support the primary selection separately from
244the clipboard).
245
246Similarly, Emacs by default does not retrieve text from the clipboard
247when the mouse (e.g., mouse-2) is used for pasting text selected in
4c0f50c9
EZ
248another application. Mouse commands that paste text retrieve text
249from the primary selection, on systems that support it separately from
250the clipboard. Text from the clipboard is retrieved only by C-y, M-y
251and other commands that yank text from the kill-ring.
7c9b11be
EZ
252
253In other words, the default behavior is that mouse gestures that
4c0f50c9
EZ
254select and paste text work with the primary selection (on X), while
255keyboard commands that kill/copy and paste text work with the
256clipboard.
7c9b11be
EZ
257
258This change also means that the "Copy", "Cut", and "Paste" items of
259the menu-bar "Edit" menu are now exactly equivalent to, respectively
260M-w, C-w, and C-y.
261
262To get back the previous behavior, whereby mouse gestures set the
263clipboard and retrieve text from there, customize the variables
4c0f50c9
EZ
264`mouse-drag-copy-region' and (on X only) `x-select-enable-primary' to
265non-nil values. If you don't want Emacs to put the text into the
266clipboard, only to the primary selection, additionally customize
7c9b11be
EZ
267`x-select-enable-clipboard' to nil.
268
269These changes in the default behavior are reflected in the default
270values of several variables:
271
7c23dd44 272*** `select-active-regions' now defaults to t, so active regions set
7c9b11be 273the primary selection. It was nil in previous versions.
7c23dd44 274
d1b08c88 275It also accepts a new value, `only', which means to only set the
7c23dd44
CY
276primary selection for temporarily active regions (usually made by
277mouse-dragging or shift-selection).
278
279*** `mouse-2' is now bound to `mouse-yank-primary'.
7c9b11be 280Previously, it was bound to `mouse-yank-at-click' (which is now
4c0f50c9 281unbound by default).
f9d71b42 282
7c9b11be 283*** `x-select-enable-clipboard' now defaults to t on all platforms.
7c23dd44 284Thus, killing and yanking now use the clipboard (in addition to the
7c9b11be
EZ
285kill ring). Note that this variable was already non-nil by default on
286MS-Windows, which does not support the primary selection between
287applications.
f9d71b42 288
2490cbbc 289*** `x-select-enable-primary' now defaults to nil.
7c9b11be
EZ
290This variable exists only on X; its default value was t in previous
291versions.
2490cbbc 292
f9d71b42 293*** `mouse-drag-copy-region' now defaults to nil.
7c9b11be 294Its previous default value was t.
f9d71b42 295
084e6df3
JD
296*** Support for X cut buffers has been removed.
297

eb199145 299* Changes in Specialized Modes and Packages in Emacs 24.1
efeb796b 300
b879a6e2
SM
301** latex-electric-env-pair-mode keeps \begin..\end matched on the fly.
302
360ac530 303** FIXME: xdg-open for browse-url and reportbug, 2010/08.
0ac3effe 304
b3671a51
JL
305** Archive Mode has basic support to browse 7z archives.
306
8a8d54cd
VD
307** ERC changes
308
309*** New vars `erc-autojoin-timing' and `erc-autojoin-delay'.
310If the value of `erc-autojoin-timing' is 'ident, ERC autojoins after a
311successful NickServ identification, or after `erc-autojoin-delay'
312seconds. The default value, 'ident, means to autojoin immediately
313after connecting.
314
27d3cd56
CY
315** In ido-mode, C-v is no longer bound to ido-toggle-vc.
316The reason is that this interferes with cua-mode.
317
c1e25821 318** partial-completion-mode is now obsolete.
79ccd68f
SM
319You can get a comparable behavior with:
320(setq completion-styles '(partial-completion initials))
321(setq completion-pcm-complete-word-inserts-delimiters t)
c1e25821 322
18c812bd 323** mpc.el: Can use pseudo tags of the form tag1|tag2 as a union of two tags.
b2957ea8 324
cf16af42
GM
325** Calendar, Diary, and Appt
326
327---
328*** The obsolete (since Emacs 22.1) method of enabling the appt package
329by adding appt-make-list to diary-hook has been removed. Use appt-activate.
330
331---
332*** Some appt variables (obsolete since Emacs 22.1) have been removed:
333appt-issue-message (use the function appt-activate)
334appt-visible/appt-msg-window (use the variable appt-display-format)
335
336---
337*** Some diary function aliases (obsolete since Emacs 22.1) have been removed:
338view-diary-entries, list-diary-entries, show-all-diary-entries
339
52834b6b
CY
340** Customize
341
342*** Customize buffers now contain a search field.
343The search is performed using `customize-apropos'.
344To turn off the search field, set custom-search-field to nil .
345
346*** Custom options now start out hidden if at their default values.
347Use the arrow to the left of the option name to toggle visibility.
348
349*** custom-buffer-sort-alphabetically now defaults to t.
350
351*** The color widget now has a "Choose" button, which allows you to
352choose a color via list-colors-display.
353
f5d6548a
JL
354** Dired-x
355
356*** dired-jump and dired-jump-other-window called with a prefix argument
357read a file name from the minibuffer instead of using buffer-file-name.
358
855a2294
DN
359** VC and related modes
360
e97a42c1 361*** New VC commands: vc-log-incoming, vc-log-outgoing, vc-find-conflicted-file.
31527c56 362
6941ffec
DN
363**** vc-log-incoming for Git runs "git fetch" so that the necessary
364data is available locally.
365
eccdfe5f
DN
366**** vc-log-incoming and vc-log-outgoing for Git require version 1.7 (or newer).
367
54d3626e
DN
368*** New key bindings: C-x v I and C-x v O bound to vc-log-incoming and
369vc-log-outgoing, respectively.
370
1fbcf428
DN
371*** The 'g' key in VC diff, log, log-incoming and log-outgoing buffers
372reruns the corresponding VC command to compute an up to date version
373of the buffer.
374
855a2294
DN
375*** vc-dir for Bzr supports viewing shelve contents and shelving snapshots.
376
09158997 377*** Special markup can be added to log-edit buffers.
e97a42c1
SM
378The log-edit buffers are expected to have a format similar to email messages
379with headers of the form:
380 Author: <author of this change>
381 Summary: <one line summary of this change>
382 Fixes: <reference to the bug fixed by this change>
383Some backends handle some of those headers specially, but any unknown header
384is just left as is in the message, so it is not lost.
09158997 385
fab43c76
DN
386**** vc-git handles Author: and Date:
387**** vc-hg handles Author: and Date:
388**** vc-bzr handles Author:, Date: and Fixes:
389**** vc-mtn handles Author: and Date:
390
b3d42406
DN
391*** Pressing g in a *vc-diff* buffer reruns vc-diff, so it will
392produce an up to date diff.
393
8117868f
DN
394** Directory local variables can apply to file-less buffers.
395For example, adding "(diff-mode . ((mode . whitespace)))" to your
d8004abe 396.dir-locals.el file, will turn on `whitespace-mode' for *vc-diff* buffers.
8117868f 397
7492acc9
MM
398** SQL Mode enhancements.
399
30c4d8dc
MM
400*** Several variables have been marked as safe local variables. The
401variables `sql-product', `sql-user', `sql-server', `sql-database' and
402`sql-port' can now be safely used as local variables.
7492acc9 403
9250002f
MM
404*** `sql-dialect' is a synonym for `sql-product'.
405
74790210 406*** Added ability to login with a port on MySQL and Postgres.
7492acc9 407The custom variable `sql-port' can be specified for connection to
74790210
MM
408MySQL or Postgres servers. By default, the port is not listed in
409either login parameter, but will be added to the command line if set
410to a non-zero value.
7492acc9 411
9250002f
MM
412*** Dynamic selection of product in an SQL interactive session.
413If you use `sql-product-interactive' to start an SQL interactive
414session it uses the current value of `sql-product'. Preceding the
415invocation with C-u will force it to ask for the product before
416creating the session.
417
418*** Renaming a SQL interactive buffer when it is created.
419Prefixing the SQL interactive commands (`sql-sqlite', `sql-postgres',
420`sql-mysql', etc.) with C-u will force a new interactive session to be
421started and will prompt for the new name. This will reduce the need
422for `sql-rename-buffer' is most common use cases.
423
3bd2cfef
MM
424*** Command continuation prompts in SQL interactive mode are suppressed.
425Multiple line commands in SQL interactive mode, generate command
426continuation prompts which needlessly confuse the output. These
427prompts are now filtered out from the output. This change impacts
428multiple line SQL statements entered with C-j between each line,
429statements yanked into the buffer and statements sent with
430`sql-send-*' functions.
431

432*** Custom variables control prompting for login parameters.
433Each supported product has a custom variable `sql-*-login-params'
434which is a list of the parameters to be prompted for before a
435connection is established.
436
74790210
MM
437The lists consist of the following five tokens: `user', `password',
438`database', `server', and `port'. The order in which they appear is
439the order in which they are prompted. The tokens symbols can be
440replaced by a sublist starting with the token and followed by a plist
441which control the prompting for values. The tokens `user',
442`database', and `server' each can take a property of :default which
443specifies the value to be used if no value is entered. The
444`database', `server', and `port' tokens handle the :completion
445property which restricts the entry to either one of the values in the
446list or to one of the values returned by the function provided as the
447property value. The `database' and `server' tokens also accept the
448:file property whose value is a regexp to identify useful file names.
449
450 (user :default DEF)
451 (database :default DEF
452 :file FILEPAT
453 :completion COMPLETE)
454 (server :default DEF
455 :file FILEPAT
456 :completion COMPLETE)
457
458The FILEPAT when :file is specified is a regexp that will match valid
459file names (without the directory portion). Generally these strings
460will be of the form ".+\.SUF" where SUF is the desired file suffix.
461
462When :completion is specified, the COMPLETE corresponds to the
463PREDICATE argument to the `completing-read' function (a list of
464possible values or a function returning such a list).
5474c40f 465
30c4d8dc
MM
466*** Added `sql-connection-alist' to record login parameter values.
467An alist for recording different username, database and server
468values. If there are multiple databases that you connect to the
469parameters needed can be stored in this alist.
470
471For example, the following might be set in the user's init.el:
472
473 (setq sql-connection-alist
474 '((dev (sql-product 'sqlite)
475 (sql-database "/home/mmaug/dev.db"))
476 (prd (sql-product 'oracle)
477 (sql-user "mmaug")
478 (sql-database "iprd2a"))))
479
480This defines two connections named "dev" and "prd".
481
482*** Added `sql-connect' to use predefined connections.
483Sets the login parameters based on the values in the
484`sql-connection-alist' and start a SQL interactive session. Any
485values specified in the connection will not be prompted for.
486
487In the example above, if the user were to invoke M-x sql-connect, they
488would be prompted for the connection. The user can respond with
489either "dev" or "prd". The "dev" connection would connect to the
490SQLite database without prompting; the "prd" connection would prompt
491for the users password and then connect to the Oracle database.
492
d26b0ea9 493**** Added SQL->Start... submenu when connections are defined.
b2957ea8 494When connections have been defined, there is a submenu available that
d26b0ea9
MM
495allows the user to select one to start a SQLi session. The "Start
496SQLi Session" item moves to the "Start..." submenu when cnnections
497have been defined.
498
499**** Added "Save Connection" menu item in SQLi buffers.
500When a SQLi session is not started by a connection then
501`sql-save-connection' will gather the login params specified for the
502session and save them as a new connection.
503
74790210
MM
504*** List database objects and details.
505Once a SQL interactive session has been started, you can get a list of
506the objects in the database and see details of those objects. The
507objects shown and the details available are product specific.
508
509**** List all objects.
510Using `M-x sql-list-all', `C-c C-l a' or selecting "SQL->List all
511objects" will list all the objects in the database. At a minimum it
512lists the tables and views in the database. Preceeding the command by
513universal argument may provide additional details or extend the
514listing to include other schemas objects. The list will appear in a
515separate window in view-mode.
516
517**** List Table details.
518Using `M-x sql-list-table', `C-c C-l t' or selecting "SQL->List Table
519details" will ask for the name of a database table or view and display
520the list of columns in the relation. Preceeding the comand with the
521universal argument may provide additional details about each column.
522The list will appear in a separate window in view-mode.
523
7492acc9
MM
524*** Added option `sql-send-terminator'.
525When set makes sure that each command sent with `sql-send-*' commands
526are properly terminated and submitted to the SQL processor.
527
528*** Added option `sql-oracle-scan-on'.
529When set commands sent to Oracle's SQL*Plus are scanned for strings
30c4d8dc
MM
530starting with an ampersand and the user is asked for replacement text.
531In general, the SQL*Plus option SCAN should always be set OFF under
532SQL interactive mode and this option used in its place.
7492acc9
MM
533
534*** SQL interactive mode will replace tabs with spaces.
535This prevents the comand interpretter for MySQL and Postgres from
536listing object name completions when being sent text via
537`sql-send-*' functions.
538
539*** An API for manipulating SQL product definitions has been added.
540
5e418f17
JL
541** s-region.el is now declared obsolete, superceded by shift-select-mode
542enabled by default in 23.1.

544** gdb-mi
545
546*** GDB User Interface migrated to GDB Machine Interface and now
547supports multithread non-stop debugging and debugging of several
548threads simultaneously.
549
37221432
MA
550** D-Bus

589
590** During startup, Emacs no longer adds entries for `menu-bar-lines'
591and `tool-bar-lines' to `default-frame-alist' and
592`initial-frame-alist'. With these alist entries omitted, `make-frame'
593checks the value of the variable `menu-bar-mode'/`tool-bar-mode' to
594determine whether to create a menu-bar or tool-bar, respectively.
595If the alist entries are added, they override the value of
596`menu-bar-mode'/`tool-bar-mode'.
597

598** Regions created by mouse dragging are now normal active regions,
599similar to the ones created by shift-selection. In previous Emacs

625* Lisp changes in Emacs 24.1
9097e8af 626
2e288d54
JB
627** `image-library-alist' is renamed to `dynamic-library-alist'.
628The variable is now used to load all kind of supported dynamic libraries,
629not just image libraries. The previous name is still available as an
630obsolete alias.
631
cf38dd42
SM
632** New variable syntax-propertize-function to set syntax-table properties.
633Replaces font-lock-syntactic-keywords which are now obsolete.
634This allows syntax-table properties to be set independently from font-lock:
635just call syntax-propertize to make sure the text is propertized.
636Together with this new variable come a new hook
637syntax-propertize-extend-region-functions, as well as two helper functions:
638syntax-propertize-via-font-lock to reuse old font-lock-syntactic-keywords
639as-is; and syntax-propertize-rules which provides a new way to specify
640syntactic rules.

b2957ea8 650** `delete-file' and `delete-directory' now accept optional arg TRASH.
f1a5d776
CY
651Trashing is performed if TRASH and `delete-by-moving-to-trash' are
652both non-nil. Interactively, TRASH defaults to t, unless a prefix
653argument is supplied (see Trash changes, above).

659** Image API
660
661*** When the image type is one of listed in `image-animated-types'
1546c559 662and the number of sub-images in the image is more than one, then the
00fe2df1
JL
663new function `create-animated-image' creates an animated image where
664sub-images are displayed successively with the duration defined by
665`image-animate-max-time' and the delay between sub-images defined
666by the Graphic Control Extension of the image.
667

670** XML and HTML parsing
671
672*** If Emacs is compiled with libxml2 support (which is the default),
4b9832a6
CY
673two new Emacs Lisp-level functions are defined:
674`xml-parse-html-string-internal' (which will parse "real world" HTML)
675and `xml-parse-string-internal' (which parses XML). Both return an
676Emacs Lisp parse tree.
677
678FIXME: These should be front-ended by xml.el.

9326ba26
CY
686** Progress reporters can now "spin".
687The MIN-VALUE and MAX-VALUE arguments of `make-progress-reporter' can
688now be nil, or omitted. This makes a "non-numeric" reporter. Each
689time you call `progress-reporter-update' on that progress reporter,
690with a nil or omitted VALUE argument, the reporter message is
691displayed with a "spinning bar".
