27 | ** Configure links against libselinux if it is found. |
28 | You can disable this by using --without-selinux. | |
29 | ||
30 | --- | |
31 | ** By default, the installed Info and man pages are compressed. | |
32 | You 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. | |
37 | These provide no new functionality, they just remove the need to edit | |
38 | lib-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 |
42 | to configure. Note that other libraries used by Emacs, RSVG and GConf, |
43 | also 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. |
47 | This is only useful for Emacs developers to debug certain types of bugs. | |
b2957ea8 | 48 | This is not a new feature; only the configure flag is new. |

60 | longer 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 |
63 | from load-path. -Q now implies this. | |

68 | ** emacsclient changes |
69 | ||
70 | *** New emacsclient argument --parent-id ID can be used to open a | |
0191e222 CY |
71 | client frame in parent X window ID, via XEmbed. This works like the |
72 | --parent-id argument to Emacs. | |
73 | ||
2a847524 CY |
74 | *** If emacsclient shuts down as a result of Emacs signalling an |
75 | error, its exit status is 1. | |
76 | ||
902a6d8d SM |
77 | ** Completion can cycle, depending on completion-cycle-threshold. |

81 | +++ |
82 | ** Emacs now supports display and editing of bidirectional text. | |
f4b6ba46 EZ |
83 | |
84 | See the node "Bidirectional Editing" in the Emacs Manual for some | |
85 | initial documentation. | |
86 | ||
87 | To 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 | ||
90 | The buffer-local variable `bidi-paragraph-direction', if non-nil, | |
91 | forces each paragraph in the buffer to have its base direction | |
92 | according to the value of this variable. Possible values are | |
93 | `right-to-left' and `left-to-right'. If the value is nil (the | |
94 | default), Emacs determines the base direction of each paragraph from | |
95 | its text, as specified by the Unicode Bidirectional Algorithm. | |
96 | ||
d20e1419 EZ |
97 | The function `current-bidi-paragraph-direction' returns the actual |
98 | value of paragraph base direction at point. | |
99 | ||
f4b6ba46 EZ |
100 | Reordering of bidirectional text for display in Emacs is a "Full |
101 | bidirectionality" class implementation of the Unicode Bidirectional | |
102 | Algorithm. | |
103 | ||
46759717 EZ |
104 | Note that some advanced display features, such as overlay strings and |
105 | `display' text properties, do not yet work correctly when | |
106 | bidirectional text is reordered for display. | |
107 | ||
303500aa | 108 | ** GTK scroll-bars are now placed on the right by default. |
52834b6b CY |
109 | Use `set-scroll-bar-mode' to change this. |
110 | ||
20fe03ad | 111 | ** GTK tool bars can have just text, just images or images and text. |
d8004abe | 112 | Customize `tool-bar-style' to choose style. On a Gnome desktop, the default |
20fe03ad JD |
113 | is taken from the desktop settings. |
114 | ||
8b2dd508 JD |
115 | ** GTK tool bars can be placed on the left/right or top/bottom of the frame. |
116 | The frame-parameter tool-bar-position controls this. It takes the values | |
1c0d77cc | 117 | top, left, right or bottom. The Options => Show/Hide menu has entries |
8b2dd508 JD |
118 | for this. |
119 | ||
8740c12d | 120 | ** ImageMagick support. |
b2fa3a09 GM |
121 | It is now possible to use the ImageMagick library to load many new |
122 | image formats in Emacs. By default, Emacs links with the ImageMagick | |
123 | libraries if they are present at build time. To disable this, use | |
8ea189f7 | 124 | the configure option `--without-imagemagick'. |
16a91140 | 125 | |
8740c12d GM |
126 | The new function `imagemagick-types' returns a list of image file |
127 | extensions that your installation of ImageMagick supports. The | |
128 | function `imagemagick-register-types' enables ImageMagick support for | |
b2957ea8 | 129 | these image types, minus those listed in `imagemagick-types-inhibit'. |
16a91140 | 130 | |
8740c12d | 131 | See the Emacs Lisp Reference Manual for more information. |
16a91140 | 132 | |
3a46642b J |
133 | ** The colors for selected text (the region face) are taken from the GTK |
134 | theme when Emacs is built with GTK. | |
135 | ||
aa1859f5 J |
136 | ** Emacs uses GTK tooltips by default if built with GTK. You can turn that |
137 | off by customizing x-gtk-use-system-tooltips. | |
138 | ||
1ecb2d3f | 139 | ** Lucid menus and dialogs can display antialiased fonts if Emacs is built |
a6ac7fc4 JD |
140 | with Xft. To change font, use X resource faceName, for example: |
141 | Emacs.pane.menubar.faceName: Courier-12 | |
142 | Set faceName to none and use font to use the old X fonts. | |
99852628 | 143 | |
0eb025fb EZ |
144 | +++ |
145 | ** Enhanced support for characters that have no glyphs in available fonts | |
146 | If a character has no glyphs in any of the available fonts, Emacs by | |
147 | default will display it either as a hexadecimal code in a box or as a | |
148 | thin 1-pixel space. In addition to these two methods, Emacs can | |
149 | display these characters as empty box, as an acronym, or not display | |
150 | them at all. To change how these characters are displayed, customize | |
151 | the variable `glyphless-char-display-control'. | |
152 | ||
153 | On character terminals these methods are used for characters that | |
154 | cannot be encoded by the `terminal-coding-system'. | |
155 | ||
917794d5 CY |
156 | ** On graphical displays, the mode-line no longer ends in dashes. |
157 | ||
b7d65a5f GM |
158 | ** Basic SELinux support has been added. |
159 | This requires Emacs to be linked with libselinux at build time. | |
160 | ||
d8004abe GM |
161 | *** Emacs preserves the SELinux file context when backing up, and |
162 | optionally when copying files. To this end, copy-file has an extra | |
163 | optional argument, and backup-buffer and friends include the SELinux | |
164 | context in their return values. | |
b7d65a5f GM |
165 | |
166 | *** The new functions file-selinux-context and set-file-selinux-context | |
167 | get and set the SELinux context of a file. | |
168 | ||
a5bee597 MA |
169 | *** Tramp offers handlers for file-selinux-context and set-file-selinux-context |
170 | for remote machines which support SELinux. | |
171 | ||
9c524fcb | 172 | ** The function kill-emacs is now run upon receipt of the signals SIGTERM |
383ebd15 | 173 | and SIGHUP, and upon SIGINT in batch mode. |
9c524fcb GM |
174 | |
175 | ** kill-emacs-hook is now also run in batch mode. | |
176 | ||
79ce172a | 177 | ** New scrolling commands `scroll-up-command' and `scroll-down-command' |
7b05466f JL |
178 | (bound to C-v/[next] and M-v/[prior]) does not signal errors at top/bottom |
179 | of buffer at first key-press (instead moves to top/bottom of buffer) | |
180 | when a new variable `scroll-error-top-bottom' is non-nil. | |
79ce172a | 181 | |
5a97d2da JL |
182 | ** New scrolling commands `scroll-up-line' and `scroll-down-line' |
183 | scroll a line instead of full screen. | |
184 | ||
a4b000fb | 185 | ** New property `scroll-command' should be set on a command's symbol to |
b2957ea8 | 186 | define it as a scroll command affected by `scroll-preserve-screen-position'. |
9013a7f8 | 187 | |
f1a5d776 CY |
188 | ** Trash changes |
189 | ||
190 | *** `delete-by-moving-to-trash' now only affects commands that specify | |
191 | trashing. This avoids inadvertently trashing temporary files. | |
192 | ||
193 | *** Calling `delete-file' or `delete-directory' with a prefix argument | |
194 | now forces true deletion, regardless of `delete-by-moving-to-trash'. | |
195 | ||
f0bf7c8e JL |
196 | ** New option `list-colors-sort' defines the color sort order |
197 | for `list-colors-display'. | |
198 | ||
44198b6e CY |
199 | ** An Emacs Lisp package manager is now included. |
200 | This is a convenient way to download and install additional packages, | |
42d9cffa | 201 | from a package repository at elpa.gnu.org. |
cb6c4991 CY |
202 | |
203 | *** `M-x list-packages' shows a list of packages, which can be | |
204 | selected for installation. | |
205 | ||
206 | *** New command `describe-package', bound to `C-h P'. | |
44198b6e CY |
207 | |
208 | *** By default, all installed packages are loaded and activated | |
209 | automatically when Emacs starts up. To disable this, set | |
210 | `package-enable-at-startup' to nil. To change which packages are | |
211 | loaded, customize `package-load-list'. | |
212 | ||
f065864f CY |
213 | ** Custom Themes |
214 | ||
215 | *** `M-x customize-themes' lists Custom themes which can be enabled. | |
216 | ||
782b5e8d CY |
217 | *** New option `custom-theme-load-path' is the load path for themes. |
218 | Emacs no longer looks for custom themes in `load-path'. The default | |
219 | is to search in `custom-theme-directory', followed by a built-in theme | |
220 | directory named "themes/" in `data-directory'. | |
221 | ||
4ddf410a MA |
222 | ** The user option `remote-file-name-inhibit-cache' controls whether |
223 | the remote file-name cache is used for read access. | |
224 | ||
17284e30 GM |
225 | ** The standalone programs lib-src/digest-doc and sorted-doc have been |
226 | replaced with Lisp commands `doc-file-to-man' and `doc-file-to-info'. | |
227 | ||
f13183cf CY |
228 | ** The variable `focus-follows-mouse' now always defaults to nil. |

b350bdf2 | 232 | |
ea4f7750 GM |
233 | +++ |
234 | ** There is a new command `count-words-region', which does what you expect. | |
235 | ||
67027b49 | 236 | ** completion-at-point now handles tags and semantic completion. |
a982c7ec | 237 | |
d74cba8f MA |
238 | ** The default value of `backup-by-copying-when-mismatch' is now t. |
239 | ||
1c708c1a CY |
240 | ** The command `just-one-space' (C-SPC), if given a negative argument, |
241 | also deletes newlines around point. | |
242 | ||
b9229673 CY |
243 | ** Deletion changes |
244 | ||
245 | *** New option `delete-active-region'. | |
246 | If non-nil, C-d, [delete], and DEL delete the region if it is active | |
247 | and no prefix argument is given. If set to `kill', these commands | |
248 | kill instead. | |
249 | ||
250 | *** New command `delete-forward-char', bound to C-d and [delete]. | |
42d9cffa CY |
251 | This is meant for interactive use, and obeys `delete-active-region'. |
252 | The command `delete-char' does not obey `delete-active-region'. | |
b9229673 CY |
253 | |
254 | *** `delete-backward-char' is now a Lisp function. | |
255 | Apart from obeying `delete-active-region', its behavior is unchanged. | |
256 | However, the byte compiler now warns if it is called from Lisp; you | |
257 | should use delete-char with a negative argument instead. | |
258 | ||
259 | *** The option `mouse-region-delete-keys' has been deleted. | |
260 | ||
f9d71b42 CY |
261 | ** Selection changes. |
262 | ||
7c23dd44 | 263 | The default handling of clipboard and primary selections has been |
42d9cffa CY |
264 | changed to conform with other X applications. The exact changes are |
265 | described below; in short, mouse commands to select and paste text now | |
266 | use the primary selection, while all other commands for killing and | |
267 | yanking text now use the clipboard. | |
7c23dd44 | 268 | |
42d9cffa CY |
269 | *** Merely selecting text (e.g. with drag-mouse-1) does not add it to |
270 | the kill-ring. On systems with a primary selection separate from the | |
271 | clipboard (such as X), the selected text is put in the primary | |
272 | selection. | |
273 | ||
274 | *** mouse-2 is now bound to `mouse-yank-primary', which pastes from | |
275 | the primary selection regardless of the contents of the kill-ring. | |
276 | ||
277 | *** Commands that kill text or copy it to the kill-ring (M-w, C-w, | |
278 | C-k, etc.) also put the killed text into the clipboard. This change | |
279 | also means that the "Copy", "Cut", and "Paste" items in the "Edit" | |
280 | menu are now exactly equivalent to, respectively M-w, C-w, and C-y. | |
281 | ||
282 | *** Yank commands, such as C-y and M-y, retrieve text from the | |
283 | clipboard if it is available. | |
284 | ||
285 | *** The above changes are reflected in the following new defaults: | |
286 | ||
287 | **** `select-active-regions' now defaults to t. | |
d1b08c88 | 288 | It also accepts a new value, `only', which means to only set the |
7c23dd44 CY |
289 | primary selection for temporarily active regions (usually made by |
290 | mouse-dragging or shift-selection). | |
291 | ||
42d9cffa | 292 | **** `mouse-2' is now bound to `mouse-yank-primary'. |
7c9b11be | 293 | Previously, it was bound to `mouse-yank-at-click' (which is now |
4c0f50c9 | 294 | unbound by default). |
f9d71b42 | 295 | |
42d9cffa CY |
296 | **** `x-select-enable-clipboard' now defaults to t on all platforms. |
297 | Note that this variable was already non-nil by default on MS-Windows, | |
298 | which does not support the primary selection between applications. | |
f9d71b42 | 299 | |
42d9cffa | 300 | **** `x-select-enable-primary' now defaults to nil. |
7c9b11be EZ |
301 | This variable exists only on X; its default value was t in previous |
302 | versions. | |
2490cbbc | 303 | |
42d9cffa CY |
304 | **** `mouse-drag-copy-region' now defaults to nil. |
305 | ||
306 | *** To return to the previous behavior, where mouse commands use the | |
307 | clipboard, change `mouse-drag-copy-region' and (on X only) | |
308 | `x-select-enable-primary' to t. If you don't want Emacs to put the | |
309 | text into the clipboard, only to the primary selection, additionally | |
310 | set `x-select-enable-clipboard' to nil. | |
f9d71b42 | 311 | |
084e6df3 JD |
312 | *** Support for X cut buffers has been removed. |
313 | ||
99f053cf JA |
314 | ** New command `rectangle-number-lines', bound to `C-x r N', numbers |
315 | the lines in the current rectangle. With an prefix argument, this | |
316 | prompts for a number to count from and for a format string. | |

335 | ** ERC changes |
336 | ||
337 | *** New vars `erc-autojoin-timing' and `erc-autojoin-delay'. | |
338 | If the value of `erc-autojoin-timing' is 'ident, ERC autojoins after a | |
339 | successful NickServ identification, or after `erc-autojoin-delay' | |
340 | seconds. The default value, 'ident, means to autojoin immediately | |
341 | after connecting. | |
342 | ||
5c0c0f77 LMI |
343 | *** New variable `erc-coding-system-precedence': If we use `undecided' |
344 | as the server coding system, this variable will then be consulted. | |
345 | The default is to decode strings that can be decoded as utf-8 as | |
346 | utf-8, and do the normal `undecided' decoding for the rest. | |
347 | ||
c0e505e5 CY |
348 | ** Eshell changes |
349 | ||
350 | *** The default value of eshell-directory-name is a directory named | |
351 | "eshell" in `user-emacs-directory'. If the old "~/.eshell/" directory | |
352 | exists, that is used instead. | |
353 | ||
27d3cd56 CY |
354 | ** In ido-mode, C-v is no longer bound to ido-toggle-vc. |

404 | ** SQL Mode enhancements. |
405 | ||
30c4d8dc MM |
406 | *** Several variables have been marked as safe local variables. The |
407 | variables `sql-product', `sql-user', `sql-server', `sql-database' and | |
408 | `sql-port' can now be safely used as local variables. | |
7492acc9 | 409 | |
9250002f MM |
410 | *** `sql-dialect' is a synonym for `sql-product'. |
411 | ||
74790210 | 412 | *** Added ability to login with a port on MySQL and Postgres. |
7492acc9 | 413 | The custom variable `sql-port' can be specified for connection to |
74790210 MM |
414 | MySQL or Postgres servers. By default, the port is not listed in |
415 | either login parameter, but will be added to the command line if set | |
416 | to a non-zero value. | |
7492acc9 | 417 | |
9250002f MM |
418 | *** Dynamic selection of product in an SQL interactive session. |
419 | If you use `sql-product-interactive' to start an SQL interactive | |
420 | session it uses the current value of `sql-product'. Preceding the | |
421 | invocation with C-u will force it to ask for the product before | |
422 | creating the session. | |
423 | ||
424 | *** Renaming a SQL interactive buffer when it is created. | |
425 | Prefixing the SQL interactive commands (`sql-sqlite', `sql-postgres', | |
426 | `sql-mysql', etc.) with C-u will force a new interactive session to be | |
427 | started and will prompt for the new name. This will reduce the need | |
428 | for `sql-rename-buffer' is most common use cases. | |
429 | ||
3bd2cfef MM |
430 | *** Command continuation prompts in SQL interactive mode are suppressed. |
431 | Multiple line commands in SQL interactive mode, generate command | |
432 | continuation prompts which needlessly confuse the output. These | |
433 | prompts are now filtered out from the output. This change impacts | |
434 | multiple line SQL statements entered with C-j between each line, | |
435 | statements yanked into the buffer and statements sent with | |
436 | `sql-send-*' functions. | |
437 | ||
7492acc9 MM |
438 | *** Custom variables control prompting for login parameters. |
439 | Each supported product has a custom variable `sql-*-login-params' | |
440 | which is a list of the parameters to be prompted for before a | |
441 | connection is established. | |
442 | ||
74790210 MM |
443 | The lists consist of the following five tokens: `user', `password', |
444 | `database', `server', and `port'. The order in which they appear is | |
445 | the order in which they are prompted. The tokens symbols can be | |
446 | replaced by a sublist starting with the token and followed by a plist | |
447 | which control the prompting for values. The tokens `user', | |
448 | `database', and `server' each can take a property of :default which | |
449 | specifies the value to be used if no value is entered. The | |
450 | `database', `server', and `port' tokens handle the :completion | |
451 | property which restricts the entry to either one of the values in the | |
452 | list or to one of the values returned by the function provided as the | |
453 | property value. The `database' and `server' tokens also accept the | |
454 | :file property whose value is a regexp to identify useful file names. | |
455 | ||
456 | (user :default DEF) | |
457 | (database :default DEF | |
458 | :file FILEPAT | |
459 | :completion COMPLETE) | |
460 | (server :default DEF | |
461 | :file FILEPAT | |
462 | :completion COMPLETE) | |
463 | ||
464 | The FILEPAT when :file is specified is a regexp that will match valid | |
465 | file names (without the directory portion). Generally these strings | |
466 | will be of the form ".+\.SUF" where SUF is the desired file suffix. | |
467 | ||
468 | When :completion is specified, the COMPLETE corresponds to the | |
469 | PREDICATE argument to the `completing-read' function (a list of | |
470 | possible values or a function returning such a list). | |
5474c40f | 471 | |
30c4d8dc MM |
472 | *** Added `sql-connection-alist' to record login parameter values. |
473 | An alist for recording different username, database and server | |
474 | values. If there are multiple databases that you connect to the | |
475 | parameters needed can be stored in this alist. | |
476 | ||
477 | For example, the following might be set in the user's init.el: | |
478 | ||
479 | (setq sql-connection-alist | |
480 | '((dev (sql-product 'sqlite) | |
481 | (sql-database "/home/mmaug/dev.db")) | |
482 | (prd (sql-product 'oracle) | |
483 | (sql-user "mmaug") | |
484 | (sql-database "iprd2a")))) | |
485 | ||
486 | This defines two connections named "dev" and "prd". | |
487 | ||
488 | *** Added `sql-connect' to use predefined connections. | |
489 | Sets the login parameters based on the values in the | |
490 | `sql-connection-alist' and start a SQL interactive session. Any | |
491 | values specified in the connection will not be prompted for. | |
492 | ||
493 | In the example above, if the user were to invoke M-x sql-connect, they | |
494 | would be prompted for the connection. The user can respond with | |
495 | either "dev" or "prd". The "dev" connection would connect to the | |
496 | SQLite database without prompting; the "prd" connection would prompt | |
497 | for the users password and then connect to the Oracle database. | |
498 | ||
d26b0ea9 | 499 | **** Added SQL->Start... submenu when connections are defined. |
b2957ea8 | 500 | When connections have been defined, there is a submenu available that |
d26b0ea9 MM |
501 | allows the user to select one to start a SQLi session. The "Start |
502 | SQLi Session" item moves to the "Start..." submenu when cnnections | |
503 | have been defined. | |
504 | ||
505 | **** Added "Save Connection" menu item in SQLi buffers. | |
506 | When a SQLi session is not started by a connection then | |
507 | `sql-save-connection' will gather the login params specified for the | |
508 | session and save them as a new connection. | |
509 | ||
74790210 MM |
510 | *** List database objects and details. |
511 | Once a SQL interactive session has been started, you can get a list of | |
512 | the objects in the database and see details of those objects. The | |
513 | objects shown and the details available are product specific. | |
514 | ||
515 | **** List all objects. | |
516 | Using `M-x sql-list-all', `C-c C-l a' or selecting "SQL->List all | |
517 | objects" will list all the objects in the database. At a minimum it | |
518 | lists the tables and views in the database. Preceeding the command by | |
519 | universal argument may provide additional details or extend the | |
520 | listing to include other schemas objects. The list will appear in a | |
521 | separate window in view-mode. | |
522 | ||
523 | **** List Table details. | |
524 | Using `M-x sql-list-table', `C-c C-l t' or selecting "SQL->List Table | |
525 | details" will ask for the name of a database table or view and display | |
526 | the list of columns in the relation. Preceeding the comand with the | |
527 | universal argument may provide additional details about each column. | |
528 | The list will appear in a separate window in view-mode. | |
529 | ||
7492acc9 MM |
530 | *** Added option `sql-send-terminator'. |
531 | When set makes sure that each command sent with `sql-send-*' commands | |
532 | are properly terminated and submitted to the SQL processor. | |
533 | ||
534 | *** Added option `sql-oracle-scan-on'. | |
535 | When set commands sent to Oracle's SQL*Plus are scanned for strings | |
30c4d8dc MM |
536 | starting with an ampersand and the user is asked for replacement text. |
537 | In general, the SQL*Plus option SCAN should always be set OFF under | |
538 | SQL interactive mode and this option used in its place. | |
7492acc9 MM |
539 | |
540 | *** SQL interactive mode will replace tabs with spaces. | |
541 | This prevents the comand interpretter for MySQL and Postgres from | |
542 | listing object name completions when being sent text via | |
543 | `sql-send-*' functions. | |
544 | ||
545 | *** An API for manipulating SQL product definitions has been added. | |
546 | ||
723ee192 SM |
547 | ** sregex.el is now obsolete, since rx.el is a strict superset. |
548 | ||
5e418f17 JL |
549 | ** s-region.el is now declared obsolete, superceded by shift-select-mode |
550 | enabled by default in 23.1. | |
551 | ||
691cf4a0 NR |
552 | ** gdb-mi |
553 | ||
554 | *** GDB User Interface migrated to GDB Machine Interface and now | |
555 | supports multithread non-stop debugging and debugging of several | |
556 | threads simultaneously. | |

560 | *** It is possible now, to access alternative buses than the default | |
561 | system or session bus. | |
562 | ||
412b9ee5 MA |
563 | *** dbus-register-{method,property} do not necessarily register names anymore. |
564 | ||
459bba37 MA |
565 | ** Tramp |
566 | ||
a808d31f MA |
567 | *** There exists a new inline access method "ksu" (kerberized su). |
568 | ||
459bba37 MA |
569 | *** The following access methods are discontinued: "ssh1_old", |
570 | "ssh2_old", "scp1_old", "scp2_old" and "fish". | |
571 | ||
0c32ce32 CY |
572 | ** VC and related modes |
573 | ||
574 | *** Support for pulling on distributed version control systems. | |
575 | The vc-update command now runs a "pull" operation, if it is supported. | |
576 | This updates the current branch from upstream. A prefix argument | |
577 | means to prompt the user for command specifics, e.g. a pull location. | |
578 | ||
579 | **** vc-pull is an alias for vc-update. | |
580 | ||
581 | **** Currently supported by Bzr. | |
582 | ||
583 | *** Support for merging on distributed version control systems. | |
584 | The vc-merge command now runs a "merge" operation, if it is supported. | |
585 | This merges another branch into the current one. A prefix argument | |
586 | means to prompt the user for command specifics, e.g. a merge location. | |
587 | ||
588 | **** Currently supported by Bzr. | |

623 | ** Passing a nil argument to a minor mode function now turns the mode |
624 | ON unconditionally. | |
6431f2e6 CY |
625 | |
626 | ** During startup, Emacs no longer adds entries for `menu-bar-lines' | |
627 | and `tool-bar-lines' to `default-frame-alist' and | |
628 | `initial-frame-alist'. With these alist entries omitted, `make-frame' | |
629 | checks the value of the variable `menu-bar-mode'/`tool-bar-mode' to | |
630 | determine whether to create a menu-bar or tool-bar, respectively. | |
631 | If the alist entries are added, they override the value of | |
632 | `menu-bar-mode'/`tool-bar-mode'. | |
633 | ||
fe0aa820 CY |
634 | ** Regions created by mouse dragging are now normal active regions, |
635 | similar to the ones created by shift-selection. In previous Emacs | |
636 | versions, these regions were delineated by `mouse-drag-overlay', which | |
637 | has now been removed. | |

672 | not just image libraries. The previous name is still available as an | |
673 | obsolete alias. | |
674 | ||
cf38dd42 SM |
675 | ** New variable syntax-propertize-function to set syntax-table properties. |
676 | Replaces font-lock-syntactic-keywords which are now obsolete. | |
677 | This allows syntax-table properties to be set independently from font-lock: | |
678 | just call syntax-propertize to make sure the text is propertized. | |
679 | Together with this new variable come a new hook | |
680 | syntax-propertize-extend-region-functions, as well as two helper functions: | |
681 | syntax-propertize-via-font-lock to reuse old font-lock-syntactic-keywords | |
