GM
27** Configure links against libselinux if it is found.
28You can disable this by using --without-selinux.

30---
31** By default, the installed Info and man pages are compressed.
32You can disable this by configuring --without-compress-info.
33
aded53ff
GM
34---
35** There are new configure options:
36--with-mmdf, --with-mail-unlink, --with-mailhost.
37These provide no new functionality, they just remove the need to edit
38lib-src/Makefile by hand in order to use the associated features.
39
e547b051 40---
30c4d8dc 41** Emacs can be compiled against Gtk+ 3.0 if you pass --with-x-toolkit=gtk3
e547b051
J
42to configure. Note that other libraries used by Emacs, RSVG and GConf,
43also depend on Gtk+. You can disable them with --without-rsvg and
44--without-gconf.
45
d9170db5
DN
46** There is a new configure option --enable-use-lisp-union-type.
47This is only useful for Emacs developers to debug certain types of bugs.
b2957ea8 48This is not a new feature; only the configure flag is new.

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.

eb199145 56* Startup Changes in Emacs 24.1
4a263588 57
198a7a97 58** The --unibyte, --multibyte, --no-multibyte, and --no-unibyte
adbf62ff
GM
59command line arguments, and the EMACS_UNIBYTE environment variable, no
60longer have any effect. (They were declared obsolete in Emacs 23.)
198a7a97 61
66b7b0fe
GM
62** New command line option `--no-site-lisp' removes site-lisp directories
63from load-path. -Q now implies this.
64
8a05b668

7841339b 69
2a847524
CY
70** emacsclient changes
71
72*** New emacsclient argument --parent-id ID can be used to open a
0191e222
CY
73client frame in parent X window ID, via XEmbed. This works like the
74--parent-id argument to Emacs.
75
15a7a774 76+++
d862b746
GM
77*** New emacsclient argument -q/--quiet suppresses some status messages.
78
2a847524
CY
79*** If emacsclient shuts down as a result of Emacs signalling an
80error, its exit status is 1.
81
902a6d8d
SM
82** Completion can cycle, depending on completion-cycle-threshold.
83
2372f278
SM
84** auto-mode-case-fold is now enabled by default.
85
f4b6ba46
EZ
86+++
87** Emacs now supports display and editing of bidirectional text.
f4b6ba46
EZ
88
89See the node "Bidirectional Editing" in the Emacs Manual for some
90initial documentation.
91
92To turn this on in any given buffer, set the buffer-local variable
93`bidi-display-reordering' to a non-nil value. The default is nil.
94
95The buffer-local variable `bidi-paragraph-direction', if non-nil,
96forces each paragraph in the buffer to have its base direction
97according to the value of this variable. Possible values are
98`right-to-left' and `left-to-right'. If the value is nil (the
99default), Emacs determines the base direction of each paragraph from
100its text, as specified by the Unicode Bidirectional Algorithm.
101
d20e1419
EZ
102The function `current-bidi-paragraph-direction' returns the actual
103value of paragraph base direction at point.
104
f4b6ba46
EZ
105Reordering of bidirectional text for display in Emacs is a "Full
106bidirectionality" class implementation of the Unicode Bidirectional
107Algorithm.
108
46759717
EZ
109Note that some advanced display features, such as overlay strings and
110`display' text properties, do not yet work correctly when
111bidirectional text is reordered for display.
112
303500aa 113** GTK scroll-bars are now placed on the right by default.
52834b6b
CY
114Use `set-scroll-bar-mode' to change this.
115
20fe03ad 116** GTK tool bars can have just text, just images or images and text.
d8004abe 117Customize `tool-bar-style' to choose style. On a Gnome desktop, the default
20fe03ad
JD
118is taken from the desktop settings.
119
8b2dd508
JD
120** GTK tool bars can be placed on the left/right or top/bottom of the frame.
121The frame-parameter tool-bar-position controls this. It takes the values
1c0d77cc 122top, left, right or bottom. The Options => Show/Hide menu has entries
8b2dd508
JD
123for this.
124
8740c12d 125** ImageMagick support.
b2fa3a09
GM
126It is now possible to use the ImageMagick library to load many new
127image formats in Emacs. By default, Emacs links with the ImageMagick
128libraries if they are present at build time. To disable this, use
8ea189f7 129the configure option `--without-imagemagick'.
16a91140 130
8740c12d
GM
131The new function `imagemagick-types' returns a list of image file
132extensions that your installation of ImageMagick supports. The
133function `imagemagick-register-types' enables ImageMagick support for
b2957ea8 134these image types, minus those listed in `imagemagick-types-inhibit'.
16a91140 135
8740c12d 136See the Emacs Lisp Reference Manual for more information.
16a91140 137
3a46642b
J
138** The colors for selected text (the region face) are taken from the GTK
139theme when Emacs is built with GTK.
140
aa1859f5
J
141** Emacs uses GTK tooltips by default if built with GTK. You can turn that
142off by customizing x-gtk-use-system-tooltips.
143
1ecb2d3f 144** Lucid menus and dialogs can display antialiased fonts if Emacs is built
3928f2b6
JD
145with Xft. To change font, use the X resource font, for example:
146Emacs.pane.menubar.font: Courier-12
99852628 147
0eb025fb
EZ
148+++
149** Enhanced support for characters that have no glyphs in available fonts
150If a character has no glyphs in any of the available fonts, Emacs by
151default will display it either as a hexadecimal code in a box or as a
152thin 1-pixel space. In addition to these two methods, Emacs can
153display these characters as empty box, as an acronym, or not display
154them at all. To change how these characters are displayed, customize
155the variable `glyphless-char-display-control'.
156
157On character terminals these methods are used for characters that
158cannot be encoded by the `terminal-coding-system'.
159
917794d5
CY
160** On graphical displays, the mode-line no longer ends in dashes.
161
b7d65a5f
GM
162** Basic SELinux support has been added.
163This requires Emacs to be linked with libselinux at build time.
164
d8004abe
GM
165*** Emacs preserves the SELinux file context when backing up, and
166optionally when copying files. To this end, copy-file has an extra
167optional argument, and backup-buffer and friends include the SELinux
168context in their return values.
b7d65a5f
GM
169
170*** The new functions file-selinux-context and set-file-selinux-context
171get and set the SELinux context of a file.
172
a5bee597
MA
173*** Tramp offers handlers for file-selinux-context and set-file-selinux-context
174for remote machines which support SELinux.
175
a4180391
PE
176+++
177** The function format-time-string now supports the %N directive, for
178higher-resolution time stamps.
179
9c524fcb 180** The function kill-emacs is now run upon receipt of the signals SIGTERM
383ebd15 181and SIGHUP, and upon SIGINT in batch mode.
9c524fcb
GM
182
183** kill-emacs-hook is now also run in batch mode.
63c72eeb
GM
184If you have code that adds something to kill-emacs-hook, you should
185consider if it is still appropriate to add it in the noninteractive case.
9c524fcb 186
79ce172a 187** New scrolling commands `scroll-up-command' and `scroll-down-command'
0a19a6f8
JB
188(bound to C-v/[next] and M-v/[prior]) do not signal errors at top/bottom
189of buffer at first key-press (instead move to top/bottom of buffer)
7b05466f 190when a new variable `scroll-error-top-bottom' is non-nil.
79ce172a 191
5a97d2da
JL
192** New scrolling commands `scroll-up-line' and `scroll-down-line'
193scroll a line instead of full screen.
194
a4b000fb 195** New property `scroll-command' should be set on a command's symbol to
b2957ea8 196define it as a scroll command affected by `scroll-preserve-screen-position'.
9013a7f8 197
f1a5d776
CY
198** Trash changes
199
200*** `delete-by-moving-to-trash' now only affects commands that specify
201trashing. This avoids inadvertently trashing temporary files.
202
203*** Calling `delete-file' or `delete-directory' with a prefix argument
204now forces true deletion, regardless of `delete-by-moving-to-trash'.
205
f0bf7c8e
JL
206** New option `list-colors-sort' defines the color sort order
207for `list-colors-display'.
208
44198b6e
CY
209** An Emacs Lisp package manager is now included.
210This is a convenient way to download and install additional packages,
42d9cffa 211from a package repository at elpa.gnu.org.
cb6c4991
CY
212
213*** `M-x list-packages' shows a list of packages, which can be
214selected for installation.
215
216*** New command `describe-package', bound to `C-h P'.
44198b6e
CY
217
218*** By default, all installed packages are loaded and activated
219automatically when Emacs starts up. To disable this, set
220`package-enable-at-startup' to nil. To change which packages are
221loaded, customize `package-load-list'.
222
d221e780
CO
223** An Emacs Lisp testing tool is now included.
224Emacs Lisp developers can use this tool to write automated tests for
225their code. See the ERT info manual for details.
226
f065864f
CY
227** Custom Themes
228
229*** `M-x customize-themes' lists Custom themes which can be enabled.
230
782b5e8d
CY
231*** New option `custom-theme-load-path' is the load path for themes.
232Emacs no longer looks for custom themes in `load-path'. The default
233is to search in `custom-theme-directory', followed by a built-in theme
234directory named "themes/" in `data-directory'.
235
b7617f6d
CY
236*** New option `custom-safe-themes' records known-safe theme files.
237If a theme is not in this list, Emacs queries before loading it, and
238offers to save the theme to `custom-safe-themes' automatically. By
239default, all themes included in Emacs are treated as safe.
278f6845 240
4ddf410a
MA
241** The user option `remote-file-name-inhibit-cache' controls whether
242the remote file-name cache is used for read access.
243
17284e30
GM
244** The standalone programs lib-src/digest-doc and sorted-doc have been
245replaced with Lisp commands `doc-file-to-man' and `doc-file-to-info'.

255*** C-y in Isearch is now bound to isearch-yank-kill, instead of
256isearch-yank-line.

67027b49 264** completion-at-point now handles tags and semantic completion.
a982c7ec 265
d74cba8f
MA
266** The default value of `backup-by-copying-when-mismatch' is now t.
267
1c708c1a
CY
268** The command `just-one-space' (C-SPC), if given a negative argument,
269also deletes newlines around point.
270
b9229673
CY
271** Deletion changes
272
273*** New option `delete-active-region'.
274If non-nil, C-d, [delete], and DEL delete the region if it is active
275and no prefix argument is given. If set to `kill', these commands
276kill instead.
277
278*** New command `delete-forward-char', bound to C-d and [delete].
42d9cffa
CY
279This is meant for interactive use, and obeys `delete-active-region'.
280The command `delete-char' does not obey `delete-active-region'.
b9229673
CY
281
282*** `delete-backward-char' is now a Lisp function.
283Apart from obeying `delete-active-region', its behavior is unchanged.
284However, the byte compiler now warns if it is called from Lisp; you
285should use delete-char with a negative argument instead.
286
287*** The option `mouse-region-delete-keys' has been deleted.
288
f9d71b42
CY
289** Selection changes.
290
b1ab31ae
CY
291The default handling of clipboard and primary selections was changed
292to conform with modern X applications. In short, most commands for
293killing and yanking text now use the clipboard, while mouse commands
294use the primary selection.
295
296In the following, we provide a list of these changes, followed by a
297list of steps to get the old behavior back if you prefer that.
298
299*** `mouse-drag-copy-region' now defaults to nil.
300*** `select-active-regions' now defaults to t.
301Merely selecting text (e.g. with drag-mouse-1) no longer puts it in
302the kill-ring. The selected text is put in the primary selection, if
303the system possesses a separate primary selection facility (e.g. X).
304
305**** `select-active-regions' also accepts a new value, `only'.
306This means to only set the primary selection for temporarily active
307regions (usually made by mouse-dragging or shift-selection);
308"ordinary" active regions, such as those made with C-SPC followed by
309point motion, do not alter the primary selection.
310
311*** mouse-2 is now bound to `mouse-yank-primary'.
312This pastes from the primary selection, ignoring the kill-ring.
313Previously, mouse-2 was bound to `mouse-yank-at-click'.
314
315*** `x-select-enable-clipboard' now defaults to t on all platforms.
316*** `x-select-enable-primary' now defaults to nil.
317Thus, commands that kill text or copy it to the kill-ring (such as
318M-w, C-w, and C-k) also use the clipboard---not the primary selection.
319
320**** The "Copy", "Cut", and "Paste" items in the "Edit" menu are now
321exactly equivalent to, respectively M-w, C-w, and C-y.
322
323**** Note that on MS-Windows, `x-select-enable-clipboard' was already
324non-nil by default, as Windows does not support the primary selection
325between applications.
326
327*** To return to the previous behavior, do the following:
328
329**** Change `mouse-drag-copy-region' to t.
330**** Change `x-select-enable-primary' to t (on X only).
331**** Change `x-select-enable-clipboard' to nil.
332**** Bind `mouse-yank-at-click' to mouse-2.
f9d71b42 333
084e6df3
JD
334*** Support for X cut buffers has been removed.
335
99f053cf
JA
336** New command `rectangle-number-lines', bound to `C-x r N', numbers
337the lines in the current rectangle. With an prefix argument, this
338prompts for a number to count from and for a format string.
339
70436396
MA
340** The command shell prompts for the shell path name, when the default
341directory is a remote file name and neither environment variable
342$ESHELL nor variable `explicit-shell-file-name' is set.
343

eb199145 345* Changes in Specialized Modes and Packages in Emacs 24.1
efeb796b 346

4d0143e6
JA
350** The Landmark game is now invoked with `landmark', not `lm'.
351
04380ff1 352** Prolog mode has been completely revamped, with lots of additional
86485587 353functionality such as more intelligent indentation, electricity, support for
04380ff1
SM
354more variants, including Mercury, and a lot more.
355
78835dd0
SM
356** shell-mode can track your cwd by reading it from your prompt.
357Just set shell-dir-cookie-re to an appropriate regexp.

365** Archive Mode has basic support to browse 7z archives.
366
876d1684 367** browse-url has gotten a new variable that is used for mailto: URLs,
0a19a6f8 368`browse-url-mailto-function', which defaults to `browse-url-mail'.
876d1684 369
817b48a7
GM
370** Directory local variables can apply to file-less buffers, in certain modes
371(eg dired, vc-dir, log-edit). For example, adding
372"(diff-mode . ((mode . whitespace)))" to your .dir-locals.el file,
373will turn on `whitespace-mode' for *vc-diff* buffers. Modes should
374call `hack-dir-local-variables-non-file-buffer' to support this.
375
6640b281
GM
376+++
377** You can prevent directory local variables from applying to subdirectories.
378Add an element (subdirs . nil) to the alist portion of any variables
379settings to indicate said section should not be applied to subdirectories.
380
8a8d54cd
VD
381** ERC changes
382
383*** New vars `erc-autojoin-timing' and `erc-autojoin-delay'.
384If the value of `erc-autojoin-timing' is 'ident, ERC autojoins after a
385successful NickServ identification, or after `erc-autojoin-delay'
386seconds. The default value, 'ident, means to autojoin immediately
387after connecting.
388
5c0c0f77
LMI
389*** New variable `erc-coding-system-precedence': If we use `undecided'
390as the server coding system, this variable will then be consulted.
391The default is to decode strings that can be decoded as utf-8 as
392utf-8, and do the normal `undecided' decoding for the rest.
393
c0e505e5
CY
394** Eshell changes
395
396*** The default value of eshell-directory-name is a directory named
397"eshell" in `user-emacs-directory'. If the old "~/.eshell/" directory
398exists, that is used instead.
399
27d3cd56
CY
400** In ido-mode, C-v is no longer bound to ido-toggle-vc.
401The reason is that this interferes with cua-mode.
402
c1e25821 403** partial-completion-mode is now obsolete.
79ccd68f
SM
404You can get a comparable behavior with:
405(setq completion-styles '(partial-completion initials))
406(setq completion-pcm-complete-word-inserts-delimiters t)
c1e25821 407

GM
416---
417*** The obsolete (since Emacs 22.1) method of enabling the appt package
418by adding appt-make-list to diary-hook has been removed. Use appt-activate.
419
420---
421*** Some appt variables (obsolete since Emacs 22.1) have been removed:
422appt-issue-message (use the function appt-activate)
423appt-visible/appt-msg-window (use the variable appt-display-format)
424

452** SQL Mode enhancements.
453
9250002f
MM
454*** `sql-dialect' is a synonym for `sql-product'.
455
74790210 456*** Added ability to login with a port on MySQL and Postgres.
7492acc9 457The custom variable `sql-port' can be specified for connection to
74790210
MM
458MySQL or Postgres servers. By default, the port is not listed in
459either login parameter, but will be added to the command line if set
460to a non-zero value.
7492acc9 461
9250002f
MM
462*** Dynamic selection of product in an SQL interactive session.
463If you use `sql-product-interactive' to start an SQL interactive
464session it uses the current value of `sql-product'. Preceding the
465invocation with C-u will force it to ask for the product before
466creating the session.
467
468*** Renaming a SQL interactive buffer when it is created.
469Prefixing the SQL interactive commands (`sql-sqlite', `sql-postgres',
470`sql-mysql', etc.) with C-u will force a new interactive session to be
471started and will prompt for the new name. This will reduce the need
472for `sql-rename-buffer' is most common use cases.
473
3bd2cfef
MM
474*** Command continuation prompts in SQL interactive mode are suppressed.
475Multiple line commands in SQL interactive mode, generate command
476continuation prompts which needlessly confuse the output. These
477prompts are now filtered out from the output. This change impacts
478multiple line SQL statements entered with C-j between each line,
479statements yanked into the buffer and statements sent with
480`sql-send-*' functions.
481
7492acc9
MM
482*** Custom variables control prompting for login parameters.
483Each supported product has a custom variable `sql-*-login-params'
484which is a list of the parameters to be prompted for before a
485connection is established.
486
74790210
MM
487The lists consist of the following five tokens: `user', `password',
488`database', `server', and `port'. The order in which they appear is
489the order in which they are prompted. The tokens symbols can be
490replaced by a sublist starting with the token and followed by a plist
491which control the prompting for values. The tokens `user',
492`database', and `server' each can take a property of :default which
493specifies the value to be used if no value is entered. The
494`database', `server', and `port' tokens handle the :completion
495property which restricts the entry to either one of the values in the
496list or to one of the values returned by the function provided as the
497property value. The `database' and `server' tokens also accept the
498:file property whose value is a regexp to identify useful file names.
499
500 (user :default DEF)
501 (database :default DEF
502 :file FILEPAT
503 :completion COMPLETE)
504 (server :default DEF
505 :file FILEPAT
506 :completion COMPLETE)
507
508The FILEPAT when :file is specified is a regexp that will match valid
509file names (without the directory portion). Generally these strings
510will be of the form ".+\.SUF" where SUF is the desired file suffix.
511
512When :completion is specified, the COMPLETE corresponds to the
513PREDICATE argument to the `completing-read' function (a list of
514possible values or a function returning such a list).
5474c40f 515
30c4d8dc
MM
516*** Added `sql-connection-alist' to record login parameter values.
517An alist for recording different username, database and server
518values. If there are multiple databases that you connect to the
519parameters needed can be stored in this alist.
520
521For example, the following might be set in the user's init.el:
522
523 (setq sql-connection-alist
524 '((dev (sql-product 'sqlite)
525 (sql-database "/home/mmaug/dev.db"))
526 (prd (sql-product 'oracle)
527 (sql-user "mmaug")
528 (sql-database "iprd2a"))))
529
530This defines two connections named "dev" and "prd".
531
532*** Added `sql-connect' to use predefined connections.
533Sets the login parameters based on the values in the
534`sql-connection-alist' and start a SQL interactive session. Any
535values specified in the connection will not be prompted for.
536
537In the example above, if the user were to invoke M-x sql-connect, they
538would be prompted for the connection. The user can respond with
539either "dev" or "prd". The "dev" connection would connect to the
540SQLite database without prompting; the "prd" connection would prompt
541for the users password and then connect to the Oracle database.
542
d26b0ea9 543**** Added SQL->Start... submenu when connections are defined.
b2957ea8 544When connections have been defined, there is a submenu available that
d26b0ea9
MM
545allows the user to select one to start a SQLi session. The "Start
546SQLi Session" item moves to the "Start..." submenu when cnnections
547have been defined.
548
549**** Added "Save Connection" menu item in SQLi buffers.
550When a SQLi session is not started by a connection then
551`sql-save-connection' will gather the login params specified for the
552session and save them as a new connection.
553
74790210
MM
554*** List database objects and details.
555Once a SQL interactive session has been started, you can get a list of
556the objects in the database and see details of those objects. The
557objects shown and the details available are product specific.
558
559**** List all objects.
560Using `M-x sql-list-all', `C-c C-l a' or selecting "SQL->List all
561objects" will list all the objects in the database. At a minimum it
86485587 562lists the tables and views in the database. Preceding the command by
74790210
MM
563universal argument may provide additional details or extend the
564listing to include other schemas objects. The list will appear in a
565separate window in view-mode.
566
567**** List Table details.
568Using `M-x sql-list-table', `C-c C-l t' or selecting "SQL->List Table
569details" will ask for the name of a database table or view and display
86485587 570the list of columns in the relation. Preceding the command with the
74790210
MM
571universal argument may provide additional details about each column.
572The list will appear in a separate window in view-mode.
573
7492acc9
MM
574*** Added option `sql-send-terminator'.
575When set makes sure that each command sent with `sql-send-*' commands
576are properly terminated and submitted to the SQL processor.
577
578*** Added option `sql-oracle-scan-on'.
579When set commands sent to Oracle's SQL*Plus are scanned for strings
30c4d8dc
MM
580starting with an ampersand and the user is asked for replacement text.
581In general, the SQL*Plus option SCAN should always be set OFF under
582SQL interactive mode and this option used in its place.
7492acc9
MM
583
584*** SQL interactive mode will replace tabs with spaces.
86485587 585This prevents the command interpreter for MySQL and Postgres from
7492acc9
MM
586listing object name completions when being sent text via
587`sql-send-*' functions.
588
589*** An API for manipulating SQL product definitions has been added.

709With these alist entries omitted, `make-frame' checks the value of the
710variable `menu-bar-mode'/`tool-bar-mode' to determine whether to create
711a menu-bar or tool-bar, respectively. If the alist entries are added,
