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 | ||
1ddac986 GM |
40 | --- |
41 | ** There is a new configure option --with-crt-dir. | |
42 | This is only useful if your crt*.o files are in a non-standard location. | |
43 | ||
e547b051 | 44 | --- |
30c4d8dc | 45 | ** Emacs can be compiled against Gtk+ 3.0 if you pass --with-x-toolkit=gtk3 |
e547b051 J |
46 | to configure. Note that other libraries used by Emacs, RSVG and GConf, |
47 | also depend on Gtk+. You can disable them with --without-rsvg and | |
48 | --without-gconf. | |
49 | ||
d9170db5 DN |
50 | ** There is a new configure option --enable-use-lisp-union-type. |
51 | This is only useful for Emacs developers to debug certain types of bugs. | |
b2957ea8 | 52 | This is not a new feature; only the configure flag is new. |

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

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

eb199145 | 218 | * Editing Changes in Emacs 24.1 |
b350bdf2 | 219 | |
a982c7ec CY |
220 | ** completion-at-point is now an alias for complete-symbol. |
221 | ||
b9229673 CY |
222 | ** Deletion changes |
223 | ||
224 | *** New option `delete-active-region'. | |
225 | If non-nil, C-d, [delete], and DEL delete the region if it is active | |
226 | and no prefix argument is given. If set to `kill', these commands | |
227 | kill instead. | |
228 | ||
229 | *** New command `delete-forward-char', bound to C-d and [delete]. | |
230 | This is meant for interactive use, and obeys `delete-active-region'; | |
231 | delete-char, meant for Lisp, does not obey `delete-active-region'. | |
232 | ||
233 | *** `delete-backward-char' is now a Lisp function. | |
234 | Apart from obeying `delete-active-region', its behavior is unchanged. | |
235 | However, the byte compiler now warns if it is called from Lisp; you | |
236 | should use delete-char with a negative argument instead. | |
237 | ||
238 | *** The option `mouse-region-delete-keys' has been deleted. | |
239 | ||
f9d71b42 CY |
240 | ** Selection changes. |
241 | ||
7c23dd44 CY |
242 | The default handling of clipboard and primary selections has been |
243 | changed to conform with other X applications. | |
f9d71b42 | 244 | |
4c0f50c9 EZ |
245 | The new behavior is that by default Emacs does not put selected text |
246 | into the clipboard, and does not add it to kill-ring, merely because | |
247 | the text was selected. Only commands that kill text or copy it to the | |
7c9b11be EZ |
248 | kill-ring (C-w, M-w, C-k, etc.) put the killed text into the |
249 | clipboard. Selected text is put into the primary selection (on | |
250 | systems, such as X, that support the primary selection separately from | |
251 | the clipboard). | |
252 | ||
253 | Similarly, Emacs by default does not retrieve text from the clipboard | |
254 | when the mouse (e.g., mouse-2) is used for pasting text selected in | |
4c0f50c9 EZ |
255 | another application. Mouse commands that paste text retrieve text |
256 | from the primary selection, on systems that support it separately from | |
257 | the clipboard. Text from the clipboard is retrieved only by C-y, M-y | |
258 | and other commands that yank text from the kill-ring. | |
7c9b11be EZ |
259 | |
260 | In other words, the default behavior is that mouse gestures that | |
4c0f50c9 EZ |
261 | select and paste text work with the primary selection (on X), while |
262 | keyboard commands that kill/copy and paste text work with the | |
263 | clipboard. | |
7c9b11be EZ |
264 | |
265 | This change also means that the "Copy", "Cut", and "Paste" items of | |
266 | the menu-bar "Edit" menu are now exactly equivalent to, respectively | |
267 | M-w, C-w, and C-y. | |
268 | ||
269 | To get back the previous behavior, whereby mouse gestures set the | |
270 | clipboard and retrieve text from there, customize the variables | |
4c0f50c9 EZ |
271 | `mouse-drag-copy-region' and (on X only) `x-select-enable-primary' to |
272 | non-nil values. If you don't want Emacs to put the text into the | |
273 | clipboard, only to the primary selection, additionally customize | |
7c9b11be EZ |
274 | `x-select-enable-clipboard' to nil. |
275 | ||
276 | These changes in the default behavior are reflected in the default | |
277 | values of several variables: | |
278 | ||
7c23dd44 | 279 | *** `select-active-regions' now defaults to t, so active regions set |
7c9b11be | 280 | the primary selection. It was nil in previous versions. |
7c23dd44 | 281 | |
d1b08c88 | 282 | It also accepts a new value, `only', which means to only set the |
7c23dd44 CY |
283 | primary selection for temporarily active regions (usually made by |
284 | mouse-dragging or shift-selection). | |
285 | ||
286 | *** `mouse-2' is now bound to `mouse-yank-primary'. | |
7c9b11be | 287 | Previously, it was bound to `mouse-yank-at-click' (which is now |
4c0f50c9 | 288 | unbound by default). |
f9d71b42 | 289 | |
7c9b11be | 290 | *** `x-select-enable-clipboard' now defaults to t on all platforms. |
7c23dd44 | 291 | Thus, killing and yanking now use the clipboard (in addition to the |
7c9b11be EZ |
292 | kill ring). Note that this variable was already non-nil by default on |
293 | MS-Windows, which does not support the primary selection between | |
294 | applications. | |
f9d71b42 | 295 | |
2490cbbc | 296 | *** `x-select-enable-primary' now defaults to nil. |
7c9b11be EZ |
297 | This variable exists only on X; its default value was t in previous |
298 | versions. | |
2490cbbc | 299 | |
f9d71b42 | 300 | *** `mouse-drag-copy-region' now defaults to nil. |
7c9b11be | 301 | Its previous default value was t. |
f9d71b42 | 302 | |
084e6df3 JD |
303 | *** Support for X cut buffers has been removed. |
304 | ||
9bae34bf | 305 | \f |
eb199145 | 306 | * Changes in Specialized Modes and Packages in Emacs 24.1 |
efeb796b | 307 | |
b879a6e2 SM |
308 | ** latex-electric-env-pair-mode keeps \begin..\end matched on the fly. |

360ac530 | 310 | ** FIXME: xdg-open for browse-url and reportbug, 2010/08. |
0ac3effe | 311 | |
b3671a51 JL |
312 | ** Archive Mode has basic support to browse 7z archives. |
313 | ||
8a8d54cd VD |
314 | ** ERC changes |
315 | ||
316 | *** New vars `erc-autojoin-timing' and `erc-autojoin-delay'. | |
317 | If the value of `erc-autojoin-timing' is 'ident, ERC autojoins after a | |
318 | successful NickServ identification, or after `erc-autojoin-delay' | |
319 | seconds. The default value, 'ident, means to autojoin immediately | |
320 | after connecting. | |
321 | ||
27d3cd56 CY |
322 | ** In ido-mode, C-v is no longer bound to ido-toggle-vc. |
323 | The reason is that this interferes with cua-mode. | |
324 | ||
c1e25821 | 325 | ** partial-completion-mode is now obsolete. |
79ccd68f SM |
326 | You can get a comparable behavior with: |
327 | (setq completion-styles '(partial-completion initials)) | |
328 | (setq completion-pcm-complete-word-inserts-delimiters t) | |
c1e25821 | 329 | |

334 | ** Calendar, Diary, and Appt |
335 | ||
336 | --- | |
337 | *** The obsolete (since Emacs 22.1) method of enabling the appt package | |
338 | by adding appt-make-list to diary-hook has been removed. Use appt-activate. | |
339 | ||
340 | --- | |
341 | *** Some appt variables (obsolete since Emacs 22.1) have been removed: | |
342 | appt-issue-message (use the function appt-activate) | |
343 | appt-visible/appt-msg-window (use the variable appt-display-format) | |
344 | ||
345 | --- | |
346 | *** Some diary function aliases (obsolete since Emacs 22.1) have been removed: | |
347 | view-diary-entries, list-diary-entries, show-all-diary-entries | |
348 | ||
52834b6b CY |
349 | ** Customize |
350 | ||
351 | *** Customize buffers now contain a search field. | |
352 | The search is performed using `customize-apropos'. | |
353 | To turn off the search field, set custom-search-field to nil . | |
354 | ||
355 | *** Custom options now start out hidden if at their default values. | |
356 | Use the arrow to the left of the option name to toggle visibility. | |
357 | ||
358 | *** custom-buffer-sort-alphabetically now defaults to t. | |
359 | ||
360 | *** The color widget now has a "Choose" button, which allows you to | |
361 | choose a color via list-colors-display. | |
362 | ||
f5d6548a JL |
363 | ** Dired-x |
364 | ||
365 | *** dired-jump and dired-jump-other-window called with a prefix argument | |
366 | read a file name from the minibuffer instead of using buffer-file-name. | |
367 | ||
855a2294 DN |
368 | ** VC and related modes |
369 | ||
e97a42c1 | 370 | *** New VC commands: vc-log-incoming, vc-log-outgoing, vc-find-conflicted-file. |
31527c56 | 371 | |
6941ffec DN |
372 | **** vc-log-incoming for Git runs "git fetch" so that the necessary |
373 | data is available locally. | |
374 | ||
eccdfe5f DN |
375 | **** vc-log-incoming and vc-log-outgoing for Git require version 1.7 (or newer). |
376 | ||
54d3626e DN |
377 | *** New key bindings: C-x v I and C-x v O bound to vc-log-incoming and |
378 | vc-log-outgoing, respectively. | |
379 | ||
1fbcf428 DN |

09158997 | 386 | *** Special markup can be added to log-edit buffers. |
e97a42c1 SM |
387 | The log-edit buffers are expected to have a format similar to email messages |
388 | with headers of the form: | |
389 | Author: <author of this change> | |
390 | Summary: <one line summary of this change> | |
391 | Fixes: <reference to the bug fixed by this change> | |
392 | Some backends handle some of those headers specially, but any unknown header | |
393 | is just left as is in the message, so it is not lost. | |

403 | ** Directory local variables can apply to file-less buffers. |
404 | For example, adding "(diff-mode . ((mode . whitespace)))" to your | |

407 | ** SQL Mode enhancements. |
408 | ||
30c4d8dc MM |
409 | *** Several variables have been marked as safe local variables. The |
410 | variables `sql-product', `sql-user', `sql-server', `sql-database' and | |
411 | `sql-port' can now be safely used as local variables. | |
7492acc9 | 412 | |
9250002f MM |
413 | *** `sql-dialect' is a synonym for `sql-product'. |
414 | ||
74790210 | 415 | *** Added ability to login with a port on MySQL and Postgres. |
7492acc9 | 416 | The custom variable `sql-port' can be specified for connection to |
74790210 MM |
417 | MySQL or Postgres servers. By default, the port is not listed in |
418 | either login parameter, but will be added to the command line if set | |
419 | to a non-zero value. | |
7492acc9 | 420 | |
9250002f MM |
421 | *** Dynamic selection of product in an SQL interactive session. |
422 | If you use `sql-product-interactive' to start an SQL interactive | |
423 | session it uses the current value of `sql-product'. Preceding the | |
424 | invocation with C-u will force it to ask for the product before | |
425 | creating the session. | |
426 | ||
427 | *** Renaming a SQL interactive buffer when it is created. | |
428 | Prefixing the SQL interactive commands (`sql-sqlite', `sql-postgres', | |
429 | `sql-mysql', etc.) with C-u will force a new interactive session to be | |
430 | started and will prompt for the new name. This will reduce the need | |
431 | for `sql-rename-buffer' is most common use cases. | |
432 | ||
3bd2cfef MM |
433 | *** Command continuation prompts in SQL interactive mode are suppressed. |
434 | Multiple line commands in SQL interactive mode, generate command | |
435 | continuation prompts which needlessly confuse the output. These | |
436 | prompts are now filtered out from the output. This change impacts | |
437 | multiple line SQL statements entered with C-j between each line, | |
438 | statements yanked into the buffer and statements sent with | |
439 | `sql-send-*' functions. | |
440 | ||
7492acc9 MM |
441 | *** Custom variables control prompting for login parameters. |
442 | Each supported product has a custom variable `sql-*-login-params' | |
443 | which is a list of the parameters to be prompted for before a | |
444 | connection is established. | |
445 | ||
74790210 MM |
446 | The lists consist of the following five tokens: `user', `password', |
447 | `database', `server', and `port'. The order in which they appear is | |
448 | the order in which they are prompted. The tokens symbols can be | |
449 | replaced by a sublist starting with the token and followed by a plist | |
450 | which control the prompting for values. The tokens `user', | |
451 | `database', and `server' each can take a property of :default which | |
452 | specifies the value to be used if no value is entered. The | |
453 | `database', `server', and `port' tokens handle the :completion | |
454 | property which restricts the entry to either one of the values in the | |
455 | list or to one of the values returned by the function provided as the | |
456 | property value. The `database' and `server' tokens also accept the | |
457 | :file property whose value is a regexp to identify useful file names. | |
458 | ||
459 | (user :default DEF) | |
460 | (database :default DEF | |
461 | :file FILEPAT | |
462 | :completion COMPLETE) | |
463 | (server :default DEF | |
464 | :file FILEPAT | |
465 | :completion COMPLETE) | |
466 | ||
467 | The FILEPAT when :file is specified is a regexp that will match valid | |
468 | file names (without the directory portion). Generally these strings | |
469 | will be of the form ".+\.SUF" where SUF is the desired file suffix. | |
470 | ||
471 | When :completion is specified, the COMPLETE corresponds to the | |
472 | PREDICATE argument to the `completing-read' function (a list of | |
473 | possible values or a function returning such a list). | |
5474c40f | 474 | |
30c4d8dc MM |
475 | *** Added `sql-connection-alist' to record login parameter values. |
476 | An alist for recording different username, database and server | |
477 | values. If there are multiple databases that you connect to the | |
478 | parameters needed can be stored in this alist. | |
479 | ||
480 | For example, the following might be set in the user's init.el: | |
481 | ||
482 | (setq sql-connection-alist | |
483 | '((dev (sql-product 'sqlite) | |
484 | (sql-database "/home/mmaug/dev.db")) | |
485 | (prd (sql-product 'oracle) | |
486 | (sql-user "mmaug") | |
487 | (sql-database "iprd2a")))) | |
488 | ||
489 | This defines two connections named "dev" and "prd". | |
490 | ||
491 | *** Added `sql-connect' to use predefined connections. | |
492 | Sets the login parameters based on the values in the | |
493 | `sql-connection-alist' and start a SQL interactive session. Any | |
494 | values specified in the connection will not be prompted for. | |
495 | ||
496 | In the example above, if the user were to invoke M-x sql-connect, they | |
497 | would be prompted for the connection. The user can respond with | |
498 | either "dev" or "prd". The "dev" connection would connect to the | |
499 | SQLite database without prompting; the "prd" connection would prompt | |
500 | for the users password and then connect to the Oracle database. | |
501 | ||
d26b0ea9 | 502 | **** Added SQL->Start... submenu when connections are defined. |
b2957ea8 | 503 | When connections have been defined, there is a submenu available that |
d26b0ea9 MM |
504 | allows the user to select one to start a SQLi session. The "Start |
505 | SQLi Session" item moves to the "Start..." submenu when cnnections | |
506 | have been defined. | |
507 | ||
508 | **** Added "Save Connection" menu item in SQLi buffers. | |
509 | When a SQLi session is not started by a connection then | |
510 | `sql-save-connection' will gather the login params specified for the | |
511 | session and save them as a new connection. | |
512 | ||
74790210 MM |
513 | *** List database objects and details. |
514 | Once a SQL interactive session has been started, you can get a list of | |
515 | the objects in the database and see details of those objects. The | |
516 | objects shown and the details available are product specific. | |
517 | ||
518 | **** List all objects. | |
519 | Using `M-x sql-list-all', `C-c C-l a' or selecting "SQL->List all | |
520 | objects" will list all the objects in the database. At a minimum it | |
521 | lists the tables and views in the database. Preceeding the command by | |
522 | universal argument may provide additional details or extend the | |
523 | listing to include other schemas objects. The list will appear in a | |
524 | separate window in view-mode. | |
525 | ||
526 | **** List Table details. | |
527 | Using `M-x sql-list-table', `C-c C-l t' or selecting "SQL->List Table | |
528 | details" will ask for the name of a database table or view and display | |
529 | the list of columns in the relation. Preceeding the comand with the | |
530 | universal argument may provide additional details about each column. | |
531 | The list will appear in a separate window in view-mode. | |
532 | ||
7492acc9 MM |
533 | *** Added option `sql-send-terminator'. |
534 | When set makes sure that each command sent with `sql-send-*' commands | |
535 | are properly terminated and submitted to the SQL processor. | |
536 | ||
537 | *** Added option `sql-oracle-scan-on'. | |
538 | When set commands sent to Oracle's SQL*Plus are scanned for strings | |
30c4d8dc MM |
539 | starting with an ampersand and the user is asked for replacement text. |
540 | In general, the SQL*Plus option SCAN should always be set OFF under | |
541 | SQL interactive mode and this option used in its place. | |
7492acc9 MM |
542 | |
543 | *** SQL interactive mode will replace tabs with spaces. | |
544 | This prevents the comand interpretter for MySQL and Postgres from | |
545 | listing object name completions when being sent text via | |
546 | `sql-send-*' functions. | |
547 | ||
548 | *** An API for manipulating SQL product definitions has been added. | |
549 | ||
5e418f17 JL |
550 | ** s-region.el is now declared obsolete, superceded by shift-select-mode |
551 | enabled by default in 23.1. | |
552 | ||
691cf4a0 NR |
553 | ** gdb-mi |
554 | ||
555 | *** GDB User Interface migrated to GDB Machine Interface and now | |
556 | supports multithread non-stop debugging and debugging of several | |
557 | threads simultaneously. | |
558 | ||
37221432 MA |
559 | ** D-Bus |
560 | ||
561 | *** It is possible now, to access alternative buses than the default | |
562 | system or session bus. | |
563 | ||
459bba37 MA |
564 | ** Tramp |
565 | ||
566 | *** The following access methods are discontinued: "ssh1_old", | |
567 | "ssh2_old", "scp1_old", "scp2_old" and "fish". | |

579 | interface to password managers like GNOME Keyring or KDE Wallet. The | |
065f2743 MA |
580 | Secret Service API requires D-Bus for communication. The command |
581 | `secrets-show-secrets' offers a buffer with a visualization of the | |
582 | secrets. | |

588 | * Incompatible Lisp Changes in Emacs 24.1 | |
6dfcbe31 | 589 | |
c4d17d50 SM |
590 | ** Remove obsolete name `e' (use `float-e' instead). |
591 | ||
288cf4e9 SM |
592 | ** A backquote not followed by a space is now always treated as new-style. |
593 | ||
fd5c9dfa | 594 | ** Test for special mode-class was moved from view-file to view-buffer. |
288cf4e9 SM |
595 | FIXME: This only says what was changed, but not what are the |
596 | programmer-visible consequences. | |
fd5c9dfa | 597 | |
3b7e1d5f SM |
598 | ** Passing a nil argument to a minor mode function now turns the mode |
599 | ON unconditionally. | |
6431f2e6 CY |
600 | |
601 | ** During startup, Emacs no longer adds entries for `menu-bar-lines' | |
602 | and `tool-bar-lines' to `default-frame-alist' and | |
603 | `initial-frame-alist'. With these alist entries omitted, `make-frame' | |
604 | checks the value of the variable `menu-bar-mode'/`tool-bar-mode' to | |
605 | determine whether to create a menu-bar or tool-bar, respectively. | |
606 | If the alist entries are added, they override the value of | |
607 | `menu-bar-mode'/`tool-bar-mode'. | |
608 | ||
fe0aa820 CY |
609 | ** Regions created by mouse dragging are now normal active regions, |
610 | similar to the ones created by shift-selection. In previous Emacs | |
611 | versions, these regions were delineated by `mouse-drag-overlay', which | |
612 | has now been removed. | |
d6d8ee7a | 613 | |
4583e796 GM |

638 | * Lisp changes in Emacs 24.1 | |
9097e8af | 639 | |
2e288d54 JB |
640 | ** `image-library-alist' is renamed to `dynamic-library-alist'. |
641 | The variable is now used to load all kind of supported dynamic libraries, | |
642 | not just image libraries. The previous name is still available as an | |
643 | obsolete alias. | |
644 | ||
cf38dd42 SM |
645 | ** New variable syntax-propertize-function to set syntax-table properties. |
646 | Replaces font-lock-syntactic-keywords which are now obsolete. | |
647 | This allows syntax-table properties to be set independently from font-lock: | |
648 | just call syntax-propertize to make sure the text is propertized. | |
649 | Together with this new variable come a new hook | |
650 | syntax-propertize-extend-region-functions, as well as two helper functions: | |
651 | syntax-propertize-via-font-lock to reuse old font-lock-syntactic-keywords | |
652 | as-is; and syntax-propertize-rules which provides a new way to specify | |
653 | syntactic rules. | |
654 | ||
a2e5caf7 SM |
655 | ** New hook post-self-insert-hook run at the end of self-insert-command. |
656 | ||
7cf78aac | 657 | +++ |
c5683ceb | 658 | ** Syntax tables support a new "comment style c" additionally to style b. |
4e2db1fe | 659 | ** frame-local variables cannot be let-bound any more. |
10dcc561 | 660 | ** prog-mode is a new major-mode meant to be the parent of programming mode. |
f44379e7 SM |
661 | ** define-minor-mode accepts a new keyword :variable. |
662 | ||
b2957ea8 | 663 | ** `delete-file' and `delete-directory' now accept optional arg TRASH. |
f1a5d776 CY |
664 | Trashing is performed if TRASH and `delete-by-moving-to-trash' are |
665 | both non-nil. Interactively, TRASH defaults to t, unless a prefix | |
666 | argument is supplied (see Trash changes, above). | |
53967e09 | 667 | |
8f92b8ad SM |
668 | ** buffer-substring-filters is obsoleted by filter-buffer-substring-functions. |
669 | ||
00278747 SM |
670 | ** New completion style `substring'. |
671 | ||
9317e499 CY |
672 | ** `facemenu-read-color' is now an alias for `read-color'. |
673 | The command `read-color' now requires a match for a color name or RGB | |
674 | triplet, instead of signalling an error if the user provides a invalid | |
675 | input. | |
676 | ||
677 | ||

678 | ** Image API |
679 | ||
680 | *** When the image type is one of listed in `image-animated-types' | |
1546c559 | 681 | and the number of sub-images in the image is more than one, then the |
00fe2df1 JL |
682 | new function `create-animated-image' creates an animated image where |
683 | sub-images are displayed successively with the duration defined by | |
684 | `image-animate-max-time' and the delay between sub-images defined | |
685 | by the Graphic Control Extension of the image. | |
686 | ||
1546c559 JL |
687 | *** `image-extension-data' is renamed to `image-metadata'. |
688 | ||
71c17aec LMI |
689 | ** XML and HTML parsing |
690 | ||
691 | *** If Emacs is compiled with libxml2 support (which is the default), | |
4b9832a6 CY |
692 | two new Emacs Lisp-level functions are defined: |
693 | `xml-parse-html-string-internal' (which will parse "real world" HTML) | |
694 | and `xml-parse-string-internal' (which parses XML). Both return an | |
695 | Emacs Lisp parse tree. | |
696 | ||
697 | FIXME: These should be front-ended by xml.el. | |
698 | ||
cf16af42 | 699 | ** FIXME GnuTLS |
71c17aec | 700 | |

703 | *** New hook `isearch-update-post-hook' that runs in `isearch-update'. | |
704 | ||
9326ba26 CY |
705 | ** Progress reporters can now "spin". |
706 | The MIN-VALUE and MAX-VALUE arguments of `make-progress-reporter' can | |
707 | now be nil, or omitted. This makes a "non-numeric" reporter. Each | |
708 | time you call `progress-reporter-update' on that progress reporter, | |
709 | with a nil or omitted VALUE argument, the reporter message is | |
710 | displayed with a "spinning bar". | |
