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
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.
d9170db5 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.

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.

7841339b 67
2a847524
CY
68** emacsclient changes
69
70*** New emacsclient argument --parent-id ID can be used to open a
0191e222
CY
71client frame in parent X window ID, via XEmbed. This works like the
72--parent-id argument to Emacs.
73
15a7a774 74+++
d862b746
GM
75*** New emacsclient argument -q/--quiet suppresses some status messages.
76
2a847524
CY
77*** If emacsclient shuts down as a result of Emacs signalling an
78error, its exit status is 1.
79
902a6d8d
SM
80** Completion can cycle, depending on completion-cycle-threshold.
81
2372f278
SM
82** auto-mode-case-fold is now enabled by default.
83
f4b6ba46
EZ
84+++
85** Emacs now supports display and editing of bidirectional text.
f4b6ba46
EZ
86
87See the node "Bidirectional Editing" in the Emacs Manual for some
88initial documentation.
89
90To turn this on in any given buffer, set the buffer-local variable
91`bidi-display-reordering' to a non-nil value. The default is nil.
92
93The buffer-local variable `bidi-paragraph-direction', if non-nil,
94forces each paragraph in the buffer to have its base direction
95according to the value of this variable. Possible values are
96`right-to-left' and `left-to-right'. If the value is nil (the
97default), Emacs determines the base direction of each paragraph from
98its text, as specified by the Unicode Bidirectional Algorithm.
99
d20e1419
EZ
100The function `current-bidi-paragraph-direction' returns the actual
101value of paragraph base direction at point.
102
f4b6ba46
EZ
103Reordering of bidirectional text for display in Emacs is a "Full
104bidirectionality" class implementation of the Unicode Bidirectional
105Algorithm.
106
46759717
EZ
107Note that some advanced display features, such as overlay strings and
108`display' text properties, do not yet work correctly when
109bidirectional text is reordered for display.
110
303500aa 111** GTK scroll-bars are now placed on the right by default.
52834b6b
CY
112Use `set-scroll-bar-mode' to change this.
113
20fe03ad 114** GTK tool bars can have just text, just images or images and text.
d8004abe 115Customize `tool-bar-style' to choose style. On a Gnome desktop, the default
20fe03ad
JD
116is taken from the desktop settings.
117
8b2dd508
JD
118** GTK tool bars can be placed on the left/right or top/bottom of the frame.
119The frame-parameter tool-bar-position controls this. It takes the values
1c0d77cc 120top, left, right or bottom. The Options => Show/Hide menu has entries
8b2dd508
JD
121for this.
122
8740c12d 123** ImageMagick support.
b2fa3a09
GM
124It is now possible to use the ImageMagick library to load many new
125image formats in Emacs. By default, Emacs links with the ImageMagick
126libraries if they are present at build time. To disable this, use
8ea189f7 127the configure option `--without-imagemagick'.
16a91140 128
8740c12d
GM
129The new function `imagemagick-types' returns a list of image file
130extensions that your installation of ImageMagick supports. The
131function `imagemagick-register-types' enables ImageMagick support for
b2957ea8 132these image types, minus those listed in `imagemagick-types-inhibit'.
16a91140 133
8740c12d 134See the Emacs Lisp Reference Manual for more information.
16a91140 135
3a46642b
J
136** The colors for selected text (the region face) are taken from the GTK
137theme when Emacs is built with GTK.
138
aa1859f5
J
139** Emacs uses GTK tooltips by default if built with GTK. You can turn that
140off by customizing x-gtk-use-system-tooltips.
141
1ecb2d3f 142** Lucid menus and dialogs can display antialiased fonts if Emacs is built
3928f2b6
JD
143with Xft. To change font, use the X resource font, for example:
144Emacs.pane.menubar.font: Courier-12
99852628 145
0eb025fb
EZ
146+++
147** Enhanced support for characters that have no glyphs in available fonts
148If a character has no glyphs in any of the available fonts, Emacs by
149default will display it either as a hexadecimal code in a box or as a
150thin 1-pixel space. In addition to these two methods, Emacs can
151display these characters as empty box, as an acronym, or not display
152them at all. To change how these characters are displayed, customize
153the variable `glyphless-char-display-control'.
154
155On character terminals these methods are used for characters that
156cannot be encoded by the `terminal-coding-system'.
157
917794d5
CY
158** On graphical displays, the mode-line no longer ends in dashes.
159
b7d65a5f
GM
160** Basic SELinux support has been added.
161This requires Emacs to be linked with libselinux at build time.
162
d8004abe
GM
163*** Emacs preserves the SELinux file context when backing up, and
164optionally when copying files. To this end, copy-file has an extra
165optional argument, and backup-buffer and friends include the SELinux
166context in their return values.
b7d65a5f
GM
167
168*** The new functions file-selinux-context and set-file-selinux-context
169get and set the SELinux context of a file.
170
a5bee597
MA
171*** Tramp offers handlers for file-selinux-context and set-file-selinux-context
172for remote machines which support SELinux.
173
a4180391
PE
174+++
175** The function format-time-string now supports the %N directive, for
176higher-resolution time stamps.
177
9c524fcb 178** The function kill-emacs is now run upon receipt of the signals SIGTERM
383ebd15 179and SIGHUP, and upon SIGINT in batch mode.
9c524fcb
GM
180
181** kill-emacs-hook is now also run in batch mode.
63c72eeb
GM
182If you have code that adds something to kill-emacs-hook, you should
183consider if it is still appropriate to add it in the noninteractive case.
9c524fcb 184
79ce172a 185** New scrolling commands `scroll-up-command' and `scroll-down-command'
7b05466f
JL
186(bound to C-v/[next] and M-v/[prior]) does not signal errors at top/bottom
187of buffer at first key-press (instead moves to top/bottom of buffer)
188when a new variable `scroll-error-top-bottom' is non-nil.
79ce172a 189
5a97d2da
JL
190** New scrolling commands `scroll-up-line' and `scroll-down-line'
191scroll a line instead of full screen.
192
a4b000fb 193** New property `scroll-command' should be set on a command's symbol to
b2957ea8 194define it as a scroll command affected by `scroll-preserve-screen-position'.
9013a7f8 195
f1a5d776
CY
196** Trash changes
197
198*** `delete-by-moving-to-trash' now only affects commands that specify
199trashing. This avoids inadvertently trashing temporary files.
200
201*** Calling `delete-file' or `delete-directory' with a prefix argument
202now forces true deletion, regardless of `delete-by-moving-to-trash'.
203
f0bf7c8e
JL
204** New option `list-colors-sort' defines the color sort order
205for `list-colors-display'.
206
44198b6e
CY
207** An Emacs Lisp package manager is now included.
208This is a convenient way to download and install additional packages,
42d9cffa 209from a package repository at elpa.gnu.org.
cb6c4991
CY
210
211*** `M-x list-packages' shows a list of packages, which can be
212selected for installation.
213
214*** New command `describe-package', bound to `C-h P'.
44198b6e
CY
215
216*** By default, all installed packages are loaded and activated
217automatically when Emacs starts up. To disable this, set
218`package-enable-at-startup' to nil. To change which packages are
219loaded, customize `package-load-list'.
220
d221e780
CO
221** An Emacs Lisp testing tool is now included.
222Emacs Lisp developers can use this tool to write automated tests for
223their code. See the ERT info manual for details.
224
f065864f
CY
225** Custom Themes
226
227*** `M-x customize-themes' lists Custom themes which can be enabled.
228
782b5e8d
CY
229*** New option `custom-theme-load-path' is the load path for themes.
230Emacs no longer looks for custom themes in `load-path'. The default
231is to search in `custom-theme-directory', followed by a built-in theme
232directory named "themes/" in `data-directory'.
233
b7617f6d
CY
234*** New option `custom-safe-themes' records known-safe theme files.
235If a theme is not in this list, Emacs queries before loading it, and
236offers to save the theme to `custom-safe-themes' automatically. By
237default, all themes included in Emacs are treated as safe.
278f6845 238
4ddf410a
MA
239** The user option `remote-file-name-inhibit-cache' controls whether
240the remote file-name cache is used for read access.
241
17284e30
GM
242** The standalone programs lib-src/digest-doc and sorted-doc have been
243replaced with Lisp commands `doc-file-to-man' and `doc-file-to-info'.

f13183cf
CY
245** The variable `focus-follows-mouse' now always defaults to nil.

CY
250** Search changes
251
252+++
253*** C-y in Isearch is now bound to isearch-yank-kill, instead of
254isearch-yank-line.
255

GM
259+++
260** There is a new command `count-words-region', which does what you expect.
261
67027b49 262** completion-at-point now handles tags and semantic completion.
a982c7ec 263
d74cba8f
MA
264** The default value of `backup-by-copying-when-mismatch' is now t.
265
1c708c1a
CY
266** The command `just-one-space' (C-SPC), if given a negative argument,
267also deletes newlines around point.
268
b9229673
CY
269** Deletion changes
270
271*** New option `delete-active-region'.
272If non-nil, C-d, [delete], and DEL delete the region if it is active
273and no prefix argument is given. If set to `kill', these commands
274kill instead.
275
276*** New command `delete-forward-char', bound to C-d and [delete].
42d9cffa
CY
277This is meant for interactive use, and obeys `delete-active-region'.
278The command `delete-char' does not obey `delete-active-region'.
b9229673
CY
279
280*** `delete-backward-char' is now a Lisp function.
281Apart from obeying `delete-active-region', its behavior is unchanged.
282However, the byte compiler now warns if it is called from Lisp; you
283should use delete-char with a negative argument instead.
284
285*** The option `mouse-region-delete-keys' has been deleted.
286
f9d71b42
CY
287** Selection changes.
288
b1ab31ae
CY
289The default handling of clipboard and primary selections was changed
290to conform with modern X applications. In short, most commands for
291killing and yanking text now use the clipboard, while mouse commands
292use the primary selection.
293
294In the following, we provide a list of these changes, followed by a
295list of steps to get the old behavior back if you prefer that.
296
297*** `mouse-drag-copy-region' now defaults to nil.
298*** `select-active-regions' now defaults to t.
299Merely selecting text (e.g. with drag-mouse-1) no longer puts it in
300the kill-ring. The selected text is put in the primary selection, if
301the system possesses a separate primary selection facility (e.g. X).
302
303**** `select-active-regions' also accepts a new value, `only'.
304This means to only set the primary selection for temporarily active
305regions (usually made by mouse-dragging or shift-selection);
306"ordinary" active regions, such as those made with C-SPC followed by
307point motion, do not alter the primary selection.
308
309*** mouse-2 is now bound to `mouse-yank-primary'.
310This pastes from the primary selection, ignoring the kill-ring.
311Previously, mouse-2 was bound to `mouse-yank-at-click'.
312
313*** `x-select-enable-clipboard' now defaults to t on all platforms.
314*** `x-select-enable-primary' now defaults to nil.
315Thus, commands that kill text or copy it to the kill-ring (such as
316M-w, C-w, and C-k) also use the clipboard---not the primary selection.
317
318**** The "Copy", "Cut", and "Paste" items in the "Edit" menu are now
319exactly equivalent to, respectively M-w, C-w, and C-y.
320
321**** Note that on MS-Windows, `x-select-enable-clipboard' was already
322non-nil by default, as Windows does not support the primary selection
323between applications.
324
325*** To return to the previous behavior, do the following:
326
327**** Change `mouse-drag-copy-region' to t.
328**** Change `x-select-enable-primary' to t (on X only).
329**** Change `x-select-enable-clipboard' to nil.
330**** Bind `mouse-yank-at-click' to mouse-2.
f9d71b42 331
084e6df3
JD
332*** Support for X cut buffers has been removed.
333
99f053cf
JA
334** New command `rectangle-number-lines', bound to `C-x r N', numbers
335the lines in the current rectangle. With an prefix argument, this
336prompts for a number to count from and for a format string.
337
70436396
MA
338** The command shell prompts for the shell path name, when the default
339directory is a remote file name and neither environment variable
340$ESHELL nor variable `explicit-shell-file-name' is set.
341

eb199145 343* Changes in Specialized Modes and Packages in Emacs 24.1
efeb796b 344

346`compilation-parse-errors-function' is now obsolete.
347
4d0143e6
JA
348** The Landmark game is now invoked with `landmark', not `lm'.
349
04380ff1 350** Prolog mode has been completely revamped, with lots of additional
86485587 351functionality such as more intelligent indentation, electricity, support for
04380ff1
SM
352more variants, including Mercury, and a lot more.
353
78835dd0
SM
354** shell-mode can track your cwd by reading it from your prompt.
355Just set shell-dir-cookie-re to an appropriate regexp.

363** Archive Mode has basic support to browse 7z archives.
364
876d1684
LMI
365** browse-url has gotten a new variable that is used for mailto: URLs,
366 `browse-url-mailto-function', which defaults to `browse-url-mail'.
367
817b48a7
GM
368** Directory local variables can apply to file-less buffers, in certain modes
369(eg dired, vc-dir, log-edit). For example, adding
370"(diff-mode . ((mode . whitespace)))" to your .dir-locals.el file,
371will turn on `whitespace-mode' for *vc-diff* buffers. Modes should
372call `hack-dir-local-variables-non-file-buffer' to support this.
373
6640b281
GM
374+++
375** You can prevent directory local variables from applying to subdirectories.
376Add an element (subdirs . nil) to the alist portion of any variables
377settings to indicate said section should not be applied to subdirectories.
378
8a8d54cd
VD
379** ERC changes
380
381*** New vars `erc-autojoin-timing' and `erc-autojoin-delay'.
382If the value of `erc-autojoin-timing' is 'ident, ERC autojoins after a
383successful NickServ identification, or after `erc-autojoin-delay'
384seconds. The default value, 'ident, means to autojoin immediately
385after connecting.
386
5c0c0f77
LMI
387*** New variable `erc-coding-system-precedence': If we use `undecided'
388as the server coding system, this variable will then be consulted.
389The default is to decode strings that can be decoded as utf-8 as
390utf-8, and do the normal `undecided' decoding for the rest.
391
c0e505e5
CY
392** Eshell changes
393
394*** The default value of eshell-directory-name is a directory named
395"eshell" in `user-emacs-directory'. If the old "~/.eshell/" directory
396exists, that is used instead.
397
27d3cd56
CY
398** In ido-mode, C-v is no longer bound to ido-toggle-vc.
399The reason is that this interferes with cua-mode.
400
c1e25821 401** partial-completion-mode is now obsolete.
79ccd68f
SM
402You can get a comparable behavior with:
403(setq completion-styles '(partial-completion initials))
404(setq completion-pcm-complete-word-inserts-delimiters t)

GM
414---
415*** The obsolete (since Emacs 22.1) method of enabling the appt package
416by adding appt-make-list to diary-hook has been removed. Use appt-activate.
417
418---
419*** Some appt variables (obsolete since Emacs 22.1) have been removed:
420appt-issue-message (use the function appt-activate)
421appt-visible/appt-msg-window (use the variable appt-display-format)
422
423---
424*** Some diary function aliases (obsolete since Emacs 22.1) have been removed:
425view-diary-entries, list-diary-entries, show-all-diary-entries
426
52834b6b
CY
427** Customize

450** SQL Mode enhancements.
451
9250002f
MM
452*** `sql-dialect' is a synonym for `sql-product'.
453
74790210 454*** Added ability to login with a port on MySQL and Postgres.
7492acc9 455The custom variable `sql-port' can be specified for connection to
74790210
MM
456MySQL or Postgres servers. By default, the port is not listed in
457either login parameter, but will be added to the command line if set
458to a non-zero value.
7492acc9 459
9250002f
MM
460*** Dynamic selection of product in an SQL interactive session.
461If you use `sql-product-interactive' to start an SQL interactive
462session it uses the current value of `sql-product'. Preceding the
463invocation with C-u will force it to ask for the product before
464creating the session.
465
466*** Renaming a SQL interactive buffer when it is created.
467Prefixing the SQL interactive commands (`sql-sqlite', `sql-postgres',
468`sql-mysql', etc.) with C-u will force a new interactive session to be
469started and will prompt for the new name. This will reduce the need
470for `sql-rename-buffer' is most common use cases.
471
3bd2cfef
MM
472*** Command continuation prompts in SQL interactive mode are suppressed.
473Multiple line commands in SQL interactive mode, generate command
474continuation prompts which needlessly confuse the output. These
475prompts are now filtered out from the output. This change impacts
476multiple line SQL statements entered with C-j between each line,
477statements yanked into the buffer and statements sent with
478`sql-send-*' functions.
479
7492acc9
MM
480*** Custom variables control prompting for login parameters.
481Each supported product has a custom variable `sql-*-login-params'
482which is a list of the parameters to be prompted for before a
483connection is established.
484
74790210
MM
485The lists consist of the following five tokens: `user', `password',
486`database', `server', and `port'. The order in which they appear is
487the order in which they are prompted. The tokens symbols can be
488replaced by a sublist starting with the token and followed by a plist
489which control the prompting for values. The tokens `user',
490`database', and `server' each can take a property of :default which
491specifies the value to be used if no value is entered. The
492`database', `server', and `port' tokens handle the :completion
493property which restricts the entry to either one of the values in the
494list or to one of the values returned by the function provided as the
495property value. The `database' and `server' tokens also accept the
496:file property whose value is a regexp to identify useful file names.
497
498 (user :default DEF)
499 (database :default DEF
500 :file FILEPAT
501 :completion COMPLETE)
502 (server :default DEF
503 :file FILEPAT
504 :completion COMPLETE)
505
506The FILEPAT when :file is specified is a regexp that will match valid
507file names (without the directory portion). Generally these strings
508will be of the form ".+\.SUF" where SUF is the desired file suffix.
509
510When :completion is specified, the COMPLETE corresponds to the
511PREDICATE argument to the `completing-read' function (a list of
512possible values or a function returning such a list).
5474c40f 513
30c4d8dc
MM
514*** Added `sql-connection-alist' to record login parameter values.
515An alist for recording different username, database and server
516values. If there are multiple databases that you connect to the
517parameters needed can be stored in this alist.
518
519For example, the following might be set in the user's init.el:
520
521 (setq sql-connection-alist
522 '((dev (sql-product 'sqlite)
523 (sql-database "/home/mmaug/dev.db"))
524 (prd (sql-product 'oracle)
525 (sql-user "mmaug")
526 (sql-database "iprd2a"))))
527
528This defines two connections named "dev" and "prd".
529
530*** Added `sql-connect' to use predefined connections.
531Sets the login parameters based on the values in the
532`sql-connection-alist' and start a SQL interactive session. Any
533values specified in the connection will not be prompted for.
534
535In the example above, if the user were to invoke M-x sql-connect, they
536would be prompted for the connection. The user can respond with
537either "dev" or "prd". The "dev" connection would connect to the
538SQLite database without prompting; the "prd" connection would prompt
539for the users password and then connect to the Oracle database.
540
d26b0ea9 541**** Added SQL->Start... submenu when connections are defined.
b2957ea8 542When connections have been defined, there is a submenu available that
d26b0ea9
MM
543allows the user to select one to start a SQLi session. The "Start
544SQLi Session" item moves to the "Start..." submenu when cnnections
545have been defined.
546
547**** Added "Save Connection" menu item in SQLi buffers.
548When a SQLi session is not started by a connection then
549`sql-save-connection' will gather the login params specified for the
550session and save them as a new connection.
551
74790210
MM
552*** List database objects and details.
553Once a SQL interactive session has been started, you can get a list of
554the objects in the database and see details of those objects. The
555objects shown and the details available are product specific.
556
557**** List all objects.
558Using `M-x sql-list-all', `C-c C-l a' or selecting "SQL->List all
559objects" will list all the objects in the database. At a minimum it
86485587 560lists the tables and views in the database. Preceding the command by
74790210
MM
561universal argument may provide additional details or extend the
562listing to include other schemas objects. The list will appear in a
563separate window in view-mode.
564
565**** List Table details.
566Using `M-x sql-list-table', `C-c C-l t' or selecting "SQL->List Table
567details" will ask for the name of a database table or view and display
86485587 568the list of columns in the relation. Preceding the command with the
74790210
MM
569universal argument may provide additional details about each column.
570The list will appear in a separate window in view-mode.
571
7492acc9
MM
572*** Added option `sql-send-terminator'.
573When set makes sure that each command sent with `sql-send-*' commands
574are properly terminated and submitted to the SQL processor.
575
576*** Added option `sql-oracle-scan-on'.
577When set commands sent to Oracle's SQL*Plus are scanned for strings
30c4d8dc
MM
578starting with an ampersand and the user is asked for replacement text.
579In general, the SQL*Plus option SCAN should always be set OFF under
580SQL interactive mode and this option used in its place.
7492acc9
MM
581
582*** SQL interactive mode will replace tabs with spaces.
86485587 583This prevents the command interpreter for MySQL and Postgres from
7492acc9
MM
584listing object name completions when being sent text via
585`sql-send-*' functions.
586
587*** An API for manipulating SQL product definitions has been added.
