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
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
17284e30
GM
212** The standalone programs lib-src/digest-doc and sorted-doc have been
213replaced with Lisp commands `doc-file-to-man' and `doc-file-to-info'.
214
0bfd685e 215\f
eb199145 216* Editing Changes in Emacs 24.1
b350bdf2 217
a982c7ec
CY
218** completion-at-point is now an alias for complete-symbol.
219
b9229673
CY
220** Deletion changes
221
222*** New option `delete-active-region'.
223If non-nil, C-d, [delete], and DEL delete the region if it is active
224and no prefix argument is given. If set to `kill', these commands
225kill instead.
226
227*** New command `delete-forward-char', bound to C-d and [delete].
228This is meant for interactive use, and obeys `delete-active-region';
229delete-char, meant for Lisp, does not obey `delete-active-region'.
230
231*** `delete-backward-char' is now a Lisp function.
232Apart from obeying `delete-active-region', its behavior is unchanged.
233However, the byte compiler now warns if it is called from Lisp; you
234should use delete-char with a negative argument instead.
235
236*** The option `mouse-region-delete-keys' has been deleted.
237
f9d71b42
CY
238** Selection changes.
239
7c23dd44
CY
240The default handling of clipboard and primary selections has been
241changed to conform with other X applications.
f9d71b42 242
4c0f50c9
EZ
243The new behavior is that by default Emacs does not put selected text
244into the clipboard, and does not add it to kill-ring, merely because
245the text was selected. Only commands that kill text or copy it to the
7c9b11be
EZ
246kill-ring (C-w, M-w, C-k, etc.) put the killed text into the
247clipboard. Selected text is put into the primary selection (on
248systems, such as X, that support the primary selection separately from
249the clipboard).
250
251Similarly, Emacs by default does not retrieve text from the clipboard
252when the mouse (e.g., mouse-2) is used for pasting text selected in
4c0f50c9
EZ
253another application. Mouse commands that paste text retrieve text
254from the primary selection, on systems that support it separately from
255the clipboard. Text from the clipboard is retrieved only by C-y, M-y
256and other commands that yank text from the kill-ring.
7c9b11be
EZ
257
258In other words, the default behavior is that mouse gestures that
4c0f50c9
EZ
259select and paste text work with the primary selection (on X), while
260keyboard commands that kill/copy and paste text work with the
261clipboard.
7c9b11be
EZ
262
263This change also means that the "Copy", "Cut", and "Paste" items of
264the menu-bar "Edit" menu are now exactly equivalent to, respectively
265M-w, C-w, and C-y.
266
267To get back the previous behavior, whereby mouse gestures set the
268clipboard and retrieve text from there, customize the variables
4c0f50c9
EZ
269`mouse-drag-copy-region' and (on X only) `x-select-enable-primary' to
270non-nil values. If you don't want Emacs to put the text into the
271clipboard, only to the primary selection, additionally customize
7c9b11be
EZ
272`x-select-enable-clipboard' to nil.
273
274These changes in the default behavior are reflected in the default
275values of several variables:
276
7c23dd44 277*** `select-active-regions' now defaults to t, so active regions set
7c9b11be 278the primary selection. It was nil in previous versions.
7c23dd44 279
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
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
7c9b11be 288*** `x-select-enable-clipboard' now defaults to t on all platforms.
7c23dd44 289Thus, killing and yanking now use the clipboard (in addition to the
7c9b11be
EZ
290kill ring). Note that this variable was already non-nil by default on
291MS-Windows, which does not support the primary selection between
292applications.
f9d71b42 293
2490cbbc 294*** `x-select-enable-primary' now defaults to nil.
7c9b11be
EZ
295This variable exists only on X; its default value was t in previous
296versions.
2490cbbc 297
f9d71b42 298*** `mouse-drag-copy-region' now defaults to nil.
7c9b11be 299Its previous default value was t.
f9d71b42 300
084e6df3
JD
301*** Support for X cut buffers has been removed.
302

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

MM
429*** Command continuation prompts in SQL interactive mode are suppressed.
430Multiple line commands in SQL interactive mode, generate command
431continuation prompts which needlessly confuse the output. These
432prompts are now filtered out from the output. This change impacts
433multiple line SQL statements entered with C-j between each line,
434statements yanked into the buffer and statements sent with
435`sql-send-*' functions.
436
7492acc9
MM
437*** Custom variables control prompting for login parameters.
438Each supported product has a custom variable `sql-*-login-params'
439which is a list of the parameters to be prompted for before a
440connection is established.
441
74790210
MM
442The lists consist of the following five tokens: `user', `password',
443`database', `server', and `port'. The order in which they appear is
444the order in which they are prompted. The tokens symbols can be
445replaced by a sublist starting with the token and followed by a plist
446which control the prompting for values. The tokens `user',
447`database', and `server' each can take a property of :default which
448specifies the value to be used if no value is entered. The
449`database', `server', and `port' tokens handle the :completion
450property which restricts the entry to either one of the values in the
451list or to one of the values returned by the function provided as the
452property value. The `database' and `server' tokens also accept the
453:file property whose value is a regexp to identify useful file names.
454
455 (user :default DEF)
456 (database :default DEF
457 :file FILEPAT
458 :completion COMPLETE)
459 (server :default DEF
460 :file FILEPAT
461 :completion COMPLETE)
462
463The FILEPAT when :file is specified is a regexp that will match valid
464file names (without the directory portion). Generally these strings
465will be of the form ".+\.SUF" where SUF is the desired file suffix.
466
467When :completion is specified, the COMPLETE corresponds to the
468PREDICATE argument to the `completing-read' function (a list of
469possible values or a function returning such a list).
5474c40f 470
30c4d8dc
MM
471*** Added `sql-connection-alist' to record login parameter values.
472An alist for recording different username, database and server
473values. If there are multiple databases that you connect to the
474parameters needed can be stored in this alist.
475
476For example, the following might be set in the user's init.el:
477
478 (setq sql-connection-alist
479 '((dev (sql-product 'sqlite)
480 (sql-database "/home/mmaug/dev.db"))
481 (prd (sql-product 'oracle)
482 (sql-user "mmaug")
483 (sql-database "iprd2a"))))
484
485This defines two connections named "dev" and "prd".
486
487*** Added `sql-connect' to use predefined connections.
488Sets the login parameters based on the values in the
489`sql-connection-alist' and start a SQL interactive session. Any
490values specified in the connection will not be prompted for.
491
492In the example above, if the user were to invoke M-x sql-connect, they
493would be prompted for the connection. The user can respond with
494either "dev" or "prd". The "dev" connection would connect to the
495SQLite database without prompting; the "prd" connection would prompt
496for the users password and then connect to the Oracle database.
497
d26b0ea9 498**** Added SQL->Start... submenu when connections are defined.
b2957ea8 499When connections have been defined, there is a submenu available that
d26b0ea9
MM
500allows the user to select one to start a SQLi session. The "Start
501SQLi Session" item moves to the "Start..." submenu when cnnections
502have been defined.
503
504**** Added "Save Connection" menu item in SQLi buffers.
505When a SQLi session is not started by a connection then
506`sql-save-connection' will gather the login params specified for the
507session and save them as a new connection.
508
74790210
MM
509*** List database objects and details.
510Once a SQL interactive session has been started, you can get a list of
511the objects in the database and see details of those objects. The
512objects shown and the details available are product specific.
513
514**** List all objects.
515Using `M-x sql-list-all', `C-c C-l a' or selecting "SQL->List all
516objects" will list all the objects in the database. At a minimum it
517lists the tables and views in the database. Preceeding the command by
518universal argument may provide additional details or extend the
519listing to include other schemas objects. The list will appear in a
520separate window in view-mode.
521
522**** List Table details.
523Using `M-x sql-list-table', `C-c C-l t' or selecting "SQL->List Table
524details" will ask for the name of a database table or view and display
525the list of columns in the relation. Preceeding the comand with the
526universal argument may provide additional details about each column.
527The list will appear in a separate window in view-mode.
528
7492acc9
MM
529*** Added option `sql-send-terminator'.
530When set makes sure that each command sent with `sql-send-*' commands
531are properly terminated and submitted to the SQL processor.
532
533*** Added option `sql-oracle-scan-on'.
534When set commands sent to Oracle's SQL*Plus are scanned for strings
30c4d8dc
MM
535starting with an ampersand and the user is asked for replacement text.
536In general, the SQL*Plus option SCAN should always be set OFF under
537SQL interactive mode and this option used in its place.
7492acc9
MM
538
539*** SQL interactive mode will replace tabs with spaces.
540This prevents the comand interpretter for MySQL and Postgres from
541listing object name completions when being sent text via
542`sql-send-*' functions.
543
544*** An API for manipulating SQL product definitions has been added.
545
5e418f17
JL
546** s-region.el is now declared obsolete, superceded by shift-select-mode
547enabled by default in 23.1.

549** gdb-mi
550
551*** GDB User Interface migrated to GDB Machine Interface and now
552supports multithread non-stop debugging and debugging of several
553threads simultaneously.

594
595** During startup, Emacs no longer adds entries for `menu-bar-lines'
596and `tool-bar-lines' to `default-frame-alist' and
597`initial-frame-alist'. With these alist entries omitted, `make-frame'
598checks the value of the variable `menu-bar-mode'/`tool-bar-mode' to
599determine whether to create a menu-bar or tool-bar, respectively.
600If the alist entries are added, they override the value of
601`menu-bar-mode'/`tool-bar-mode'.
602

603** Regions created by mouse dragging are now normal active regions,
604similar to the ones created by shift-selection. In previous Emacs

630* Lisp changes in Emacs 24.1
9097e8af 631
2e288d54
JB
632** `image-library-alist' is renamed to `dynamic-library-alist'.
633The variable is now used to load all kind of supported dynamic libraries,
634not just image libraries. The previous name is still available as an
635obsolete alias.
636
cf38dd42
SM
637** New variable syntax-propertize-function to set syntax-table properties.
638Replaces font-lock-syntactic-keywords which are now obsolete.
639This allows syntax-table properties to be set independently from font-lock:
640just call syntax-propertize to make sure the text is propertized.
641Together with this new variable come a new hook
642syntax-propertize-extend-region-functions, as well as two helper functions:
643syntax-propertize-via-font-lock to reuse old font-lock-syntactic-keywords
644as-is; and syntax-propertize-rules which provides a new way to specify
645syntactic rules.
646

b2957ea8 655** `delete-file' and `delete-directory' now accept optional arg TRASH.
f1a5d776
CY
656Trashing is performed if TRASH and `delete-by-moving-to-trash' are
657both non-nil. Interactively, TRASH defaults to t, unless a prefix
658argument is supplied (see Trash changes, above).

664** Image API
665
666*** When the image type is one of listed in `image-animated-types'
1546c559 667and the number of sub-images in the image is more than one, then the
00fe2df1
JL
668new function `create-animated-image' creates an animated image where
669sub-images are displayed successively with the duration defined by
670`image-animate-max-time' and the delay between sub-images defined
671by the Graphic Control Extension of the image.
672

675** XML and HTML parsing
676
677*** If Emacs is compiled with libxml2 support (which is the default),
4b9832a6
CY
678two new Emacs Lisp-level functions are defined:
679`xml-parse-html-string-internal' (which will parse "real world" HTML)
680and `xml-parse-string-internal' (which parses XML). Both return an
681Emacs Lisp parse tree.
682
683FIXME: These should be front-ended by xml.el.

9326ba26
CY
691** Progress reporters can now "spin".
692The MIN-VALUE and MAX-VALUE arguments of `make-progress-reporter' can
693now be nil, or omitted. This makes a "non-numeric" reporter. Each
694time you call `progress-reporter-update' on that progress reporter,
695with a nil or omitted VALUE argument, the reporter message is
696displayed with a "spinning bar".
