25* Installation Changes in Emacs 24.1
26
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
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
40---
41** Emacs can be compiled against Gtk+ 3.0 if you pass --with-x-toolkit=gtk3
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
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.
48This is not a new feature; only the configure flag is new.
49
50---
51** New translation of the Emacs Tutorial in Hebrew is available
52Type `C-u C-h t' to choose it in case your language setup doesn't
53automatically select it.
54
55\f
56* Startup Changes in Emacs 24.1
57
58** The --unibyte, --multibyte, --no-multibyte, and --no-unibyte
59command line arguments, and the EMACS_UNIBYTE environment variable, no
60longer have any effect. (They were declared obsolete in Emacs 23.)
61
62** New command line option `--no-site-lisp' removes site-lisp directories
63from load-path. -Q now implies this.
64
65\f
66* Changes in Emacs 24.1
67
68** emacsclient changes
69
70*** New emacsclient argument --parent-id ID can be used to open a
71client frame in parent X window ID, via XEmbed. This works like the
72--parent-id argument to Emacs.
73
74*** If emacsclient shuts down as a result of Emacs signalling an
75error, its exit status is 1.
76
77** Completion can cycle, depending on completion-cycle-threshold.
78
79** auto-mode-case-fold is now enabled by default.
80
81+++
82** Emacs now supports display and editing of bidirectional text.
83
84See the node "Bidirectional Editing" in the Emacs Manual for some
85initial documentation.
86
87To turn this on in any given buffer, set the buffer-local variable
88`bidi-display-reordering' to a non-nil value. The default is nil.
89
90The buffer-local variable `bidi-paragraph-direction', if non-nil,
91forces each paragraph in the buffer to have its base direction
92according to the value of this variable. Possible values are
93`right-to-left' and `left-to-right'. If the value is nil (the
94default), Emacs determines the base direction of each paragraph from
95its text, as specified by the Unicode Bidirectional Algorithm.
96
97The function `current-bidi-paragraph-direction' returns the actual
98value of paragraph base direction at point.
99
100Reordering of bidirectional text for display in Emacs is a "Full
101bidirectionality" class implementation of the Unicode Bidirectional
102Algorithm.
103
104Note that some advanced display features, such as overlay strings and
105`display' text properties, do not yet work correctly when
106bidirectional text is reordered for display.
107
108** GTK scroll-bars are now placed on the right by default.
109Use `set-scroll-bar-mode' to change this.
110
111** GTK tool bars can have just text, just images or images and text.
112Customize `tool-bar-style' to choose style. On a Gnome desktop, the default
113is taken from the desktop settings.
114
115** GTK tool bars can be placed on the left/right or top/bottom of the frame.
116The frame-parameter tool-bar-position controls this. It takes the values
117top, left, right or bottom. The Options => Show/Hide menu has entries
118for this.
119
120** ImageMagick support.
121It is now possible to use the ImageMagick library to load many new
122image formats in Emacs. By default, Emacs links with the ImageMagick
123libraries if they are present at build time. To disable this, use
124the configure option `--without-imagemagick'.
125
126The new function `imagemagick-types' returns a list of image file
127extensions that your installation of ImageMagick supports. The
128function `imagemagick-register-types' enables ImageMagick support for
129these image types, minus those listed in `imagemagick-types-inhibit'.
130
131See the Emacs Lisp Reference Manual for more information.
132
133** The colors for selected text (the region face) are taken from the GTK
134theme when Emacs is built with GTK.
135
136** Emacs uses GTK tooltips by default if built with GTK. You can turn that
137off by customizing x-gtk-use-system-tooltips.
138
139** Lucid menus and dialogs can display antialiased fonts if Emacs is built
140with Xft. To change font, use the X resource font, for example:
141Emacs.pane.menubar.font: Courier-12
142
143+++
144** Enhanced support for characters that have no glyphs in available fonts
145If a character has no glyphs in any of the available fonts, Emacs by
146default will display it either as a hexadecimal code in a box or as a
147thin 1-pixel space. In addition to these two methods, Emacs can
148display these characters as empty box, as an acronym, or not display
149them at all. To change how these characters are displayed, customize
150the variable `glyphless-char-display-control'.
151
152On character terminals these methods are used for characters that
153cannot be encoded by the `terminal-coding-system'.
154
155** On graphical displays, the mode-line no longer ends in dashes.
156
157** Basic SELinux support has been added.
158This requires Emacs to be linked with libselinux at build time.
159
160*** Emacs preserves the SELinux file context when backing up, and
161optionally when copying files. To this end, copy-file has an extra
162optional argument, and backup-buffer and friends include the SELinux
163context in their return values.
164
165*** The new functions file-selinux-context and set-file-selinux-context
166get and set the SELinux context of a file.
167
168*** Tramp offers handlers for file-selinux-context and set-file-selinux-context
169for remote machines which support SELinux.
170
171+++
172** The function format-time-string now supports the %N directive, for
173higher-resolution time stamps.
174
175** The function kill-emacs is now run upon receipt of the signals SIGTERM
176and SIGHUP, and upon SIGINT in batch mode.
177
178** kill-emacs-hook is now also run in batch mode.
179
180** New scrolling commands `scroll-up-command' and `scroll-down-command'
181(bound to C-v/[next] and M-v/[prior]) does not signal errors at top/bottom
182of buffer at first key-press (instead moves to top/bottom of buffer)
183when a new variable `scroll-error-top-bottom' is non-nil.
184
185** New scrolling commands `scroll-up-line' and `scroll-down-line'
186scroll a line instead of full screen.
187
188** New property `scroll-command' should be set on a command's symbol to
189define it as a scroll command affected by `scroll-preserve-screen-position'.
190
191** Trash changes
192
193*** `delete-by-moving-to-trash' now only affects commands that specify
194trashing. This avoids inadvertently trashing temporary files.
195
196*** Calling `delete-file' or `delete-directory' with a prefix argument
197now forces true deletion, regardless of `delete-by-moving-to-trash'.
198
199** New option `list-colors-sort' defines the color sort order
200for `list-colors-display'.
201
202** An Emacs Lisp package manager is now included.
203This is a convenient way to download and install additional packages,
204from a package repository at elpa.gnu.org.
205
206*** `M-x list-packages' shows a list of packages, which can be
207selected for installation.
208
209*** New command `describe-package', bound to `C-h P'.
210
211*** By default, all installed packages are loaded and activated
212automatically when Emacs starts up. To disable this, set
213`package-enable-at-startup' to nil. To change which packages are
214loaded, customize `package-load-list'.
215
216** An Emacs Lisp testing tool is now included.
217Emacs Lisp developers can use this tool to write automated tests for
218their code. See the ERT info manual for details.
219
220** Custom Themes
221
222*** `M-x customize-themes' lists Custom themes which can be enabled.
223
224*** New option `custom-theme-load-path' is the load path for themes.
225Emacs no longer looks for custom themes in `load-path'. The default
226is to search in `custom-theme-directory', followed by a built-in theme
227directory named "themes/" in `data-directory'.
228
229*** New option `custom-safe-themes' records known-safe theme files.
230If a theme is not in this list, Emacs queries before loading it, and
231offers to save the theme to `custom-safe-themes' automatically. By
232default, all themes included in Emacs are treated as safe.
233
234** The user option `remote-file-name-inhibit-cache' controls whether
235the remote file-name cache is used for read access.
236
237** The standalone programs lib-src/digest-doc and sorted-doc have been
238replaced with Lisp commands `doc-file-to-man' and `doc-file-to-info'.
239
240** The variable `focus-follows-mouse' now always defaults to nil.
241
242\f
243* Editing Changes in Emacs 24.1
244
245+++
246** There is a new command `count-words-region', which does what you expect.
247
248** completion-at-point now handles tags and semantic completion.
249
250** The default value of `backup-by-copying-when-mismatch' is now t.
251
252** The command `just-one-space' (C-SPC), if given a negative argument,
253also deletes newlines around point.
254
255** Deletion changes
256
257*** New option `delete-active-region'.
258If non-nil, C-d, [delete], and DEL delete the region if it is active
259and no prefix argument is given. If set to `kill', these commands
260kill instead.
261
262*** New command `delete-forward-char', bound to C-d and [delete].
263This is meant for interactive use, and obeys `delete-active-region'.
264The command `delete-char' does not obey `delete-active-region'.
265
266*** `delete-backward-char' is now a Lisp function.
267Apart from obeying `delete-active-region', its behavior is unchanged.
268However, the byte compiler now warns if it is called from Lisp; you
269should use delete-char with a negative argument instead.
270
271*** The option `mouse-region-delete-keys' has been deleted.
272
273** Selection changes.
274
275The default handling of clipboard and primary selections was changed
276to conform with modern X applications. In short, most commands for
277killing and yanking text now use the clipboard, while mouse commands
278use the primary selection.
279
280In the following, we provide a list of these changes, followed by a
281list of steps to get the old behavior back if you prefer that.
282
283*** `mouse-drag-copy-region' now defaults to nil.
284*** `select-active-regions' now defaults to t.
285Merely selecting text (e.g. with drag-mouse-1) no longer puts it in
286the kill-ring. The selected text is put in the primary selection, if
287the system possesses a separate primary selection facility (e.g. X).
288
289**** `select-active-regions' also accepts a new value, `only'.
290This means to only set the primary selection for temporarily active
291regions (usually made by mouse-dragging or shift-selection);
292"ordinary" active regions, such as those made with C-SPC followed by
293point motion, do not alter the primary selection.
294
295*** mouse-2 is now bound to `mouse-yank-primary'.
296This pastes from the primary selection, ignoring the kill-ring.
297Previously, mouse-2 was bound to `mouse-yank-at-click'.
298
299*** `x-select-enable-clipboard' now defaults to t on all platforms.
300*** `x-select-enable-primary' now defaults to nil.
301Thus, commands that kill text or copy it to the kill-ring (such as
302M-w, C-w, and C-k) also use the clipboard---not the primary selection.
303
304**** The "Copy", "Cut", and "Paste" items in the "Edit" menu are now
305exactly equivalent to, respectively M-w, C-w, and C-y.
306
307**** Note that on MS-Windows, `x-select-enable-clipboard' was already
308non-nil by default, as Windows does not support the primary selection
309between applications.
310
311*** To return to the previous behavior, do the following:
312
313**** Change `mouse-drag-copy-region' to t.
314**** Change `x-select-enable-primary' to t (on X only).
315**** Change `x-select-enable-clipboard' to nil.
316**** Bind `mouse-yank-at-click' to mouse-2.
317
318*** Support for X cut buffers has been removed.
319
320** New command `rectangle-number-lines', bound to `C-x r N', numbers
321the lines in the current rectangle. With an prefix argument, this
322prompts for a number to count from and for a format string.
323
324\f
325* Changes in Specialized Modes and Packages in Emacs 24.1
326
327** The compile.el mode can be used without font-lock-mode.
328`compilation-parse-errors-function' is now obsolete.
329
330** The Landmark game is now invoked with `landmark', not `lm'.
331
332** Prolog mode has been completely revamped, with lots of additional
333functionality such as more intelligent indentation, electricty, support for
334more variants, including Mercury, and a lot more.
335
336** shell-mode can track your cwd by reading it from your prompt.
337Just set shell-dir-cookie-re to an appropriate regexp.
338
339** Modula-2 mode provides auto-indentation.
340
341** latex-electric-env-pair-mode keeps \begin..\end matched on the fly.
342
343** FIXME: xdg-open for browse-url and reportbug, 2010/08.
344
345** Archive Mode has basic support to browse 7z archives.
346
347** browse-url has gotten a new variable that is used for mailto: URLs,
348 `browse-url-mailto-function', which defaults to `browse-url-mail'.
349
350** ERC changes
351
352*** New vars `erc-autojoin-timing' and `erc-autojoin-delay'.
353If the value of `erc-autojoin-timing' is 'ident, ERC autojoins after a
354successful NickServ identification, or after `erc-autojoin-delay'
355seconds. The default value, 'ident, means to autojoin immediately
356after connecting.
357
358*** New variable `erc-coding-system-precedence': If we use `undecided'
359as the server coding system, this variable will then be consulted.
360The default is to decode strings that can be decoded as utf-8 as
361utf-8, and do the normal `undecided' decoding for the rest.
362
363** Eshell changes
364
365*** The default value of eshell-directory-name is a directory named
366"eshell" in `user-emacs-directory'. If the old "~/.eshell/" directory
367exists, that is used instead.
368
369** In ido-mode, C-v is no longer bound to ido-toggle-vc.
370The reason is that this interferes with cua-mode.
371
372** partial-completion-mode is now obsolete.
373You can get a comparable behavior with:
374(setq completion-styles '(partial-completion initials))
375(setq completion-pcm-complete-word-inserts-delimiters t)
376
377** mpc.el: Can use pseudo tags of the form tag1|tag2 as a union of two tags.
378
379** server can listen on a specific port using the server-port option.
380
381** Calendar, Diary, and Appt
382
383---
384*** The obsolete (since Emacs 22.1) method of enabling the appt package
385by adding appt-make-list to diary-hook has been removed. Use appt-activate.
386
387---
388*** Some appt variables (obsolete since Emacs 22.1) have been removed:
389appt-issue-message (use the function appt-activate)
390appt-visible/appt-msg-window (use the variable appt-display-format)
391
392---
393*** Some diary function aliases (obsolete since Emacs 22.1) have been removed:
394view-diary-entries, list-diary-entries, show-all-diary-entries
395
396** Customize
397
398*** Customize buffers now contain a search field.
399The search is performed using `customize-apropos'.
400To turn off the search field, set custom-search-field to nil.
401
402*** Custom options now start out hidden if at their default values.
403Use the arrow to the left of the option name to toggle visibility.
404
405*** custom-buffer-sort-alphabetically now defaults to t.
406
407*** The color widget now has a "Choose" button, which allows you to
408choose a color via list-colors-display.
409
410** Dired-x
411
412*** dired-jump and dired-jump-other-window called with a prefix argument
413read a file name from the minibuffer instead of using buffer-file-name.
414
415** Directory local variables can apply to file-less buffers.
416For example, adding "(diff-mode . ((mode . whitespace)))" to your
417.dir-locals.el file, will turn on `whitespace-mode' for *vc-diff* buffers.
418
419** SQL Mode enhancements.
420
421*** Several variables have been marked as safe local variables. The
422variables `sql-product', `sql-user', `sql-server', `sql-database' and
423`sql-port' can now be safely used as local variables.
424
425*** `sql-dialect' is a synonym for `sql-product'.
426
427*** Added ability to login with a port on MySQL and Postgres.
428The custom variable `sql-port' can be specified for connection to
429MySQL or Postgres servers. By default, the port is not listed in
430either login parameter, but will be added to the command line if set
431to a non-zero value.
432
433*** Dynamic selection of product in an SQL interactive session.
434If you use `sql-product-interactive' to start an SQL interactive
435session it uses the current value of `sql-product'. Preceding the
436invocation with C-u will force it to ask for the product before
437creating the session.
438
439*** Renaming a SQL interactive buffer when it is created.
440Prefixing the SQL interactive commands (`sql-sqlite', `sql-postgres',
441`sql-mysql', etc.) with C-u will force a new interactive session to be
442started and will prompt for the new name. This will reduce the need
443for `sql-rename-buffer' is most common use cases.
444
445*** Command continuation prompts in SQL interactive mode are suppressed.
446Multiple line commands in SQL interactive mode, generate command
447continuation prompts which needlessly confuse the output. These
448prompts are now filtered out from the output. This change impacts
449multiple line SQL statements entered with C-j between each line,
450statements yanked into the buffer and statements sent with
451`sql-send-*' functions.
452
453*** Custom variables control prompting for login parameters.
454Each supported product has a custom variable `sql-*-login-params'
455which is a list of the parameters to be prompted for before a
456connection is established.
457
458The lists consist of the following five tokens: `user', `password',
459`database', `server', and `port'. The order in which they appear is
460the order in which they are prompted. The tokens symbols can be
461replaced by a sublist starting with the token and followed by a plist
462which control the prompting for values. The tokens `user',
463`database', and `server' each can take a property of :default which
464specifies the value to be used if no value is entered. The
465`database', `server', and `port' tokens handle the :completion
466property which restricts the entry to either one of the values in the
467list or to one of the values returned by the function provided as the
468property value. The `database' and `server' tokens also accept the
469:file property whose value is a regexp to identify useful file names.
470
471 (user :default DEF)
472 (database :default DEF
473 :file FILEPAT
474 :completion COMPLETE)
475 (server :default DEF
476 :file FILEPAT
477 :completion COMPLETE)
478
479The FILEPAT when :file is specified is a regexp that will match valid
480file names (without the directory portion). Generally these strings
481will be of the form ".+\.SUF" where SUF is the desired file suffix.
482
483When :completion is specified, the COMPLETE corresponds to the
484PREDICATE argument to the `completing-read' function (a list of
485possible values or a function returning such a list).
486
487*** Added `sql-connection-alist' to record login parameter values.
488An alist for recording different username, database and server
489values. If there are multiple databases that you connect to the
490parameters needed can be stored in this alist.
491
492For example, the following might be set in the user's init.el:
493
494 (setq sql-connection-alist
495 '((dev (sql-product 'sqlite)
496 (sql-database "/home/mmaug/dev.db"))
497 (prd (sql-product 'oracle)
498 (sql-user "mmaug")
499 (sql-database "iprd2a"))))
500
501This defines two connections named "dev" and "prd".
502
503*** Added `sql-connect' to use predefined connections.
504Sets the login parameters based on the values in the
505`sql-connection-alist' and start a SQL interactive session. Any
506values specified in the connection will not be prompted for.
507
508In the example above, if the user were to invoke M-x sql-connect, they
509would be prompted for the connection. The user can respond with
510either "dev" or "prd". The "dev" connection would connect to the
511SQLite database without prompting; the "prd" connection would prompt
512for the users password and then connect to the Oracle database.
513
514**** Added SQL->Start... submenu when connections are defined.
515When connections have been defined, there is a submenu available that
516allows the user to select one to start a SQLi session. The "Start
517SQLi Session" item moves to the "Start..." submenu when cnnections
518have been defined.
519
520**** Added "Save Connection" menu item in SQLi buffers.
521When a SQLi session is not started by a connection then
522`sql-save-connection' will gather the login params specified for the
523session and save them as a new connection.
524
525*** List database objects and details.
526Once a SQL interactive session has been started, you can get a list of
527the objects in the database and see details of those objects. The
528objects shown and the details available are product specific.
529
530**** List all objects.
531Using `M-x sql-list-all', `C-c C-l a' or selecting "SQL->List all
532objects" will list all the objects in the database. At a minimum it
533lists the tables and views in the database. Preceeding the command by
534universal argument may provide additional details or extend the
535listing to include other schemas objects. The list will appear in a
536separate window in view-mode.
537
538**** List Table details.
539Using `M-x sql-list-table', `C-c C-l t' or selecting "SQL->List Table
540details" will ask for the name of a database table or view and display
541the list of columns in the relation. Preceeding the comand with the
542universal argument may provide additional details about each column.
543The list will appear in a separate window in view-mode.
544
545*** Added option `sql-send-terminator'.
546When set makes sure that each command sent with `sql-send-*' commands
547are properly terminated and submitted to the SQL processor.
548
549*** Added option `sql-oracle-scan-on'.
550When set commands sent to Oracle's SQL*Plus are scanned for strings
551starting with an ampersand and the user is asked for replacement text.
552In general, the SQL*Plus option SCAN should always be set OFF under
553SQL interactive mode and this option used in its place.
554
555*** SQL interactive mode will replace tabs with spaces.
556This prevents the comand interpretter for MySQL and Postgres from
557listing object name completions when being sent text via
558`sql-send-*' functions.
559
560*** An API for manipulating SQL product definitions has been added.
561
562** sregex.el is now obsolete, since rx.el is a strict superset.
563
564** s-region.el and pc-select are now declared obsolete,
565superceded by shift-select-mode enabled by default in 23.1.
566** pc-mode.el is also declared obsolete.
567** gdb-mi
568
569*** GDB User Interface migrated to GDB Machine Interface and now
570supports multithread non-stop debugging and debugging of several
571threads simultaneously.
572
573** D-Bus
574
575*** It is possible now, to access alternative buses than the default
576system or session bus.
577
578*** dbus-register-{service,method,property}
579The -method and -property functions do not automatically register
580names anymore.
581
582The new function dbus-register-service registers a service known name
583on a D-Bus without simultaneously registering a property or a method.
584
585** Tramp
586
587*** There exists a new inline access method "ksu" (kerberized su).
588
589*** The following access methods are discontinued: "ssh1_old",
590"ssh2_old", "scp1_old", "scp2_old", "imap", "imaps" and "fish".
591
592** VC and related modes
593
594*** Support for pulling on distributed version control systems.
595The vc-pull command runs a "pull" operation, if it is supported.
596This updates the current branch from upstream. A prefix argument
597means to prompt the user for specifics, e.g. a pull location.
598
599**** `vc-update' is now an alias for `vc-pull'.
600
601**** Currently supported by Bzr, Git, and Mercurial.
602
603*** Support for merging on distributed version control systems.
604The vc-merge command now runs a "merge" operation, if it is supported.
605This merges another branch into the current one. This command prompts
606the user for specifics, e.g. a merge source.
607
608**** Currently supported for Bzr, Git, and Mercurial.
609
610*** Log entries in some Log View buffers can be toggled to display a
611longer description by typing RET (log-view-toggle-entry-display).
612In the Log View buffers made by `C-x v L' (vc-print-root-log), you can
613use this to display the full log entry for the revision at point.
614
615**** Currently supported for Bzr, Git, and Mercurial.
616
617**** Packages using Log View mode can enable this functionality by
618binding `log-view-expanded-log-entry-function' to a suitable function.
619
620** Miscellaneous
621
622---
623*** `copyright-fix-years' can optionally convert consecutive years to ranges.
624
625\f
626* New Modes and Packages in Emacs 24.1
627
628** New global minor modes electric-pair-mode, electric-indent-mode,
629and electric-layout-mode.
630
631** pcase.el provides the ML-style pattern matching macro `pcase'.
632
633** secrets.el is an implementation of the Secret Service API, an
634interface to password managers like GNOME Keyring or KDE Wallet. The
635Secret Service API requires D-Bus for communication. The command
636`secrets-show-secrets' offers a buffer with a visualization of the
637secrets.
638
639** notifications.el provides an implementation of the Desktop
640Notifications API. It requires D-Bus for communication.
641
642\f
643* Incompatible Lisp Changes in Emacs 24.1
644
645** `copy-directory' now copies the source directory as a subdirectory
646of the target directory, if the latter is an existing directory. The
647new optional arg COPY-CONTENTS, if non-nil, makes the function copy
648the contents directly into a pre-existing target directory.
649
650** `compose-mail' now accepts an optional 8th arg, RETURN-ACTION, and
651passes it to the mail user agent function. This argument specifies an
652action for returning to the caller after finishing with the mail.
653This is currently used by Rmail to delete a mail window.
654
655** For mouse click input events in the text area, the Y pixel
656coordinate in the POSITION list now counts from the top of the text
657area, excluding any header line. Previously, it counted from the top
658of the header line.
659
660** Remove obsolete name `e' (use `float-e' instead).
661
662** A backquote not followed by a space is now always treated as new-style.
663
664** Test for special mode-class was moved from view-file to view-buffer.
665FIXME: This only says what was changed, but not what are the
666programmer-visible consequences.
667
668** Passing a nil argument to a minor mode function now turns the mode
669 ON unconditionally.
670
671** During startup, Emacs no longer adds entries for `menu-bar-lines'
672and `tool-bar-lines' to `default-frame-alist' and
673`initial-frame-alist'. With these alist entries omitted, `make-frame'
674checks the value of the variable `menu-bar-mode'/`tool-bar-mode' to
675determine whether to create a menu-bar or tool-bar, respectively.
676If the alist entries are added, they override the value of
677`menu-bar-mode'/`tool-bar-mode'.
678
679** Regions created by mouse dragging are now normal active regions,
680similar to the ones created by shift-selection. In previous Emacs
681versions, these regions were delineated by `mouse-drag-overlay', which
682has now been removed.
683
684** cl.el no longer provides `cl-19'.
685
686** The following functions and aliases, obsolete since at least Emacs 21.1,
687have been removed:
688comint-kill-output, decompose-composite-char, outline-visible,
689internal-find-face, internal-get-face, frame-update-faces,
690frame-update-face-colors, x-frob-font-weight, x-frob-font-slant,
691x-make-font-bold, x-make-font-demibold, x-make-font-unbold
692x-make-font-italic, x-make-font-oblique, x-make-font-unitalic
693x-make-font-bold-italic, mldrag-drag-mode-line, mldrag-drag-vertical-line,
694iswitchb-default-keybindings, char-bytes, isearch-return-char,
695make-local-hook
696
697** The following variables and aliases, obsolete since at least Emacs 21.1,
698have been removed:
699checkdoc-minor-keymap, vc-header-alist, directory-sep-char,
700font-lock-defaults-alist
701
702** The following files, obsolete since at least Emacs 21.1, have been removed:
703sc.el, x-menu.el, rnews.el, rnewspost.el
704
705** FIXME finder-inf.el changes.
706
707\f
708* Lisp changes in Emacs 24.1
709
710** Removed the stack-trace-on-error variable.
711Also the debugger can now "continue" from an error, which means it will jump
712to the error handler as if the debugger had not been invoked instead of
713jumping all the way to the top-level.
714
715** New function `read-char-choice' reads a restricted set of characters,
716discarding any inputs not inside the set.
717
718** `image-library-alist' is renamed to `dynamic-library-alist'.
719The variable is now used to load all kind of supported dynamic libraries,
720not just image libraries. The previous name is still available as an
721obsolete alias.
722
723** New variable syntax-propertize-function to set syntax-table properties.
724Replaces font-lock-syntactic-keywords which are now obsolete.
725This allows syntax-table properties to be set independently from font-lock:
726just call syntax-propertize to make sure the text is propertized.
727Together with this new variable come a new hook
728syntax-propertize-extend-region-functions, as well as two helper functions:
729syntax-propertize-via-font-lock to reuse old font-lock-syntactic-keywords
730as-is; and syntax-propertize-rules which provides a new way to specify
731syntactic rules.
732
733** New hook post-self-insert-hook run at the end of self-insert-command.
734
735+++
736** Syntax tables support a new "comment style c" additionally to style b.
737** frame-local variables cannot be let-bound any more.
738** prog-mode is a new major-mode meant to be the parent of programming mode.
739** define-minor-mode accepts a new keyword :variable.
740
741** `delete-file' and `delete-directory' now accept optional arg TRASH.
742Trashing is performed if TRASH and `delete-by-moving-to-trash' are
743both non-nil. Interactively, TRASH defaults to t, unless a prefix
744argument is supplied (see Trash changes, above).
745
746** buffer-substring-filters is obsoleted by filter-buffer-substring-functions.
747
748** New completion style `substring'.
749
750** `facemenu-read-color' is now an alias for `read-color'.
751The command `read-color' now requires a match for a color name or RGB
752triplet, instead of signalling an error if the user provides a invalid
753input.
754
755** Tool-bars can display separators.
756Tool-bar separators are handled like menu separators in menu-bar maps,
757i.e. via menu entries of the form `(menu-item "--")'.
758
759** Image API
760
761*** When the image type is one of listed in `image-animated-types'
762and the number of sub-images in the image is more than one, then the
763new function `create-animated-image' creates an animated image where
764sub-images are displayed successively with the duration defined by
765`image-animate-max-time' and the delay between sub-images defined
766by the Graphic Control Extension of the image.
767
768*** `image-extension-data' is renamed to `image-metadata'.
769
770** XML and HTML parsing
771
772*** If Emacs is compiled with libxml2 support (which is the default),
773two new Emacs Lisp-level functions are defined:
774`libxml-parse-html-region' (which will parse "real world" HTML)
775and `libxml-parse-xml-region' (which parses XML). Both return an
776Emacs Lisp parse tree.
777
778FIXME: These should be front-ended by xml.el.
779
780** FIXME GnuTLS
781
782** Isearch
783
784*** New hook `isearch-update-post-hook' that runs in `isearch-update'.
785
786** Progress reporters can now "spin".
787The MIN-VALUE and MAX-VALUE arguments of `make-progress-reporter' can
788now be nil, or omitted. This makes a "non-numeric" reporter. Each
789time you call `progress-reporter-update' on that progress reporter,
790with a nil or omitted VALUE argument, the reporter message is
791displayed with a "spinning bar".
792
793\f
794* Changes in Emacs 24.1 on non-free operating systems
795
796** New configure.bat option --enable-checking builds emacs with extra
797runtime checks.
798
799** New configure.bat option --distfiles to specify files to be
800 included in binary distribution
801
802** New make target `dist' to create binary disttribution for Windows
803 platform
