9 This file is about changes in Emacs version 25.
11 See file HISTORY for a list of GNU Emacs versions and release dates.
12 See files NEWS.24, NEWS.23, NEWS.22, NEWS.21, NEWS.20, NEWS.19, NEWS.18,
13 and NEWS.1-17 for changes in older Emacs versions.
15 You can narrow news to a specific version by calling `view-emacs-news'
16 with a prefix argument or by typing C-u C-h C-n.
19 +++ indicates that all necessary documentation updates are complete.
20 (This means all relevant manuals in doc/ AND lisp doc-strings.)
21 --- means no change in the manuals is needed.
22 When you add a new item, use the appropriate mark if you are sure it applies,
23 otherwise leave it unmarked.
26 * Installation Changes in Emacs 25.1
29 ** Building Emacs now requires C99 or later.
32 ** Building Emacs now requires GNU make, version 3.81 or later.
34 ** New configure option --with-cairo.
35 Maybe add text based on http://lists.gnu.org/archive/html/emacs-devel/2015-05/msg00689.html
37 ** By default, Emacs no longer works on IRIX. We expect that Emacs
38 users are not affected by this, as SGI stopped supporting IRIX in
39 December 2013. If you are affected, please send a bug report. You
40 should be able to work around the problem either by porting the Emacs
41 undumping code to GCC under IRIX, or by configuring --with-wide-int,
42 or by sticking with Emacs 24.4.
44 ** The Emacs garbage collector assumes GC_MARK_STACK == GC_MAKE_GCPROS_NOOPS.
45 The GC_MAKE_GCPROS_NOOPS stack-marking variant has been the default
46 since Emacs 24.4, and the other variants were undocumented and were
47 obstacles to maintenance and development. GC_MARK_STACK and its
48 related symbols have been removed from the C internals.
50 ** 'configure' now prefers gnustep-config when configuring GNUstep.
51 If gnustep-config is not available, the old heuristics are used.
54 ** 'configure' now prefers inotify to gfile for file notification,
55 unless gfile is explicitly requested via --with-file-notification='gfile'.
58 ** The configure option '--with-pkg-config-prog' has been removed.
59 Use './configure PKG_CONFIG=/full/name/of/pkg-config' if you need to.
62 ** The configure option '--with-mmdf' has been removed.
63 It was no longer useful, as it relied on libraries that are no longer
64 supported, and its presence led to confusion during configuration.
65 This affects only the 'movemail' utility; Emacs itself can still
66 process MMDF-format files as before.
68 ** The configure option '--enable-silent-rules' is now the default,
69 and silent rules are now quieter. To get the old behavior where
70 'make' chatters a lot, configure with '--disable-silent-rules' or
71 build with 'make V=1'.
74 ** The configure option '--with-gameuser' now allows to specify a
75 group instead of a user if its argument is prefixed by ':' (a colon).
76 This will cause the game score files in ${localstatedir}/games/emacs
77 to be owned by that group, and the helper program for updating them to
78 be installed setgid. The option now defaults to the 'games' group.
81 ** The `grep-changelog' script (and its manual page) are no longer included.
82 It has no particular connection to Emacs and has not changed in years,
83 so if you want to use it, you can always take a copy from an older Emacs.
85 ** Emacs 25 comes with a new set of icons.
86 Various resolutions are available as etc/images/icons/hicolor/*/apps/emacs.png.
87 The old Emacs logo icons are available as `emacs23.png' in the same location.
90 * Startup Changes in Emacs 25.1
93 ** When Emacs is given a file as a command line argument and
94 `initial-buffer-choice' is non-nil, display both the file and
95 `initial-buffer-choice'. When Emacs is given more than one file and
96 `initial-buffer-choice' is non-nil, show `initial-buffer-choice'
97 and *Buffer List*. This makes Emacs convenient to use from the
98 command line when `initial-buffer-choice' is non-nil.
101 ** The value of ‘initial-scratch-message’ is now treated as a doc string
102 and can contain escape sequences for command keys, quotes, and the like.
105 * Changes in Emacs 25.1
107 ** Any file of the form .dir-locals*.el is now considered a dir-local
108 file, and multiple can be used in the same directory. See the
109 variable `dir-locals-file' for more information.
110 ** `xref-find-definitions' and `describe-function' now display
111 information about mode local overrides (defined by
112 cedet/mode-local.el `define-overloadable-function' and
113 `define-mode-local-overrides').
115 ** New `display-buffer' action function `display-buffer-use-some-frame'
116 This displays the buffer in an existing frame other than the current
117 frame, and allows the caller to specify a frame predicate to exclude
120 ** New doc command `describe-symbol'. Works for functions, vars, faces, etc...
122 ** New user option `search-default-regexp-mode' specifies the default mode for isearch
124 ** `isearch' and `query-replace' now perform character folding in matches.
125 This is analogous to case-folding, but applies between Unicode
126 characters and their ASCII counterparts. This means many characters
127 will match entire groups of characters.
129 For instance, the " will match all variants of unicode double quotes
130 (like “ and ”), and the letter a will match all of its accented
131 cousins, even those composed of multiple characters, as well as many
132 other symbols like ℀, ℁, ⒜, and ⓐ.
134 ** New function `character-fold-to-regexp' can be used
135 by searching commands to produce a regexp matching anything that
136 character-folds into STRING.
138 ** New command `checkdoc-package-keywords' checks if the
139 current package keywords are recognized. Set the new option
140 `checkdoc-package-keywords-flag' to non-nil to make
141 `checkdoc-current-buffer' call this function automatically.
143 ** New function `checkdoc-file' checks for style errors.
144 It's meant for use together with `compile':
145 emacs -batch --eval "(checkdoc-file \"subr.el\")"
147 ** New command `comment-line' bound to `C-x C-;'.
149 ** New function `custom-prompt-customize-unsaved-options' checks for
150 unsaved customizations and prompts user to customize (if found).
153 ** Network security (TLS/SSL certificate validity and the like) is
154 added via the new Network Security Manager (NSM) and controlled via
155 the `network-security-level' variable.
157 ** C-h l now also lists the commands that were run.
160 ** The new M-s M-w key binding uses eww to search the web for the
163 ** M-x suggests shorthands and ignores obsolete commands for completion.
164 ** x-select-enable-clipboard is renamed select-enable-clipboard.
165 x-select-enable-primary and renamed select-enable-primary.
166 Additionally they both now apply to all systems (OSX, GNUstep, Windows, you
167 name it), with the proviso that on some systems (e.g. Windows)
168 select-enable-primary is ineffective since the system doesn't
169 have the equivalent of a primary selection.
172 ** terpri gets an optional arg ENSURE to conditionally output a newline.
175 ** New macro `define-advice'.
177 ** `insert-register' now leaves point after the inserted text
178 when called interactively. A prefix argument toggles this behavior.
180 ** New var `truncate-string-ellipsis' to choose how to indicate truncation.
183 ** The new variable `term-file-aliases' replaces some files from lisp/term.
184 The function `tty-run-terminal-initialization' consults this variable
185 when deciding what terminal-specific initialization code to run.
188 ** New variable `system-configuration-features', listing some of the
189 main features that Emacs was compiled with. This is mainly intended
190 for use in Emacs bug reports.
193 ** A password is now hidden also when typed in batch mode. Another
194 hiding character but the default `.' can be used by let-binding the
195 variable `read-hide-char'.
197 ** The new functions `string-collate-lessp' and `string-collate-equalp'
198 preserve the collation order as defined by the system's locale(1)
199 environment. For the time being this is implemented for modern POSIX
200 systems and for MS-Windows, for other systems they fall back to their
201 counterparts `string-lessp' and `string-equal'.
203 *** The ls-lisp package uses `string-collate-lessp' to sort file names.
204 If you want the old, locale-independent sorting, customize the new
205 option `ls-lisp-use-string-collate' to a nil value.
207 *** The MS-Windows specific variable `w32-collate-ignore-punctuation',
208 if set to a non-nil value, causes the above 2 functions to ignore
209 symbol and punctuation characters when collating strings. This
210 emulates the behavior of modern Posix platforms when the locale's
211 codeset is "UTF-8" (as in "en_US.UTF-8"). This is needed because
212 MS-Windows doesn't support UTF-8 as codeset in its locales.
215 ** The new function `bidi-find-overridden-directionality' allows to
216 find characters whose directionality was, perhaps maliciously,
217 overridden by directional override control characters. Lisp programs
218 can use this to detect potential phishing of URLs and other links that
219 exploits bidirectional display reordering.
222 ** The new function `buffer-substring-with-bidi-context' allows to
223 copy a portion of a buffer into a different location while preserving
224 the visual appearance both of the copied text and the text at
225 destination, even when the copied text includes mixed bidirectional
226 text and directional control characters.
228 ** New variable `ns-use-fullscreen-animation' controls animation for
229 non-native NS fullscreen. The default is nil. Set to t to enable
230 animation when entering and leaving fullscreen. For native OSX fullscreen
233 ** A new text property `inhibit-read-only' can be used in read-only
234 buffers to allow certain parts of the text to be writable.
236 ** A new function `directory-files-recursively' returns all matching
237 files (recursively) under a directory.
239 ** The new function `directory-name-p' can be used to check whether a file
240 name (as returned from, for instance, `file-name-all-completions' is
241 a directory file name. It returns non-nil if the last character in
242 the name is a forward slash.
245 ** New variable `fast-but-imprecise-scrolling' inhibits
246 fontification during full screen scrolling operations, giving less
247 hesitant operation during auto-repeat of C-v, M-v at the cost of
248 possible inaccuracies in the end position.
250 ** The function `font-info' now returns more details about a font.
251 In particular, it now returns the average width of the font's
252 characters, which can be used for geometry-related calculations.
254 ** A new function `default-font-width' returns the average width of a
255 character in the current buffer's default font. If the default face
256 is remapped (see `face-remapping-alist'), the value for the remapped
257 face is returned. This function complements the existing function
258 `default-font-height'.
260 ** New functions `window-font-height' and `window-font-width' return
261 the height and average width of characters in a specified face and
262 window. If FACE is remapped (see `face-remapping-alist'), the
263 function returns the information for the remapped face.
265 ** A new function `window-max-chars-per-line' returns the maximal
266 number of characters that can be displayed on one line. If a face
267 and/or window are provided, these values are used for the
268 calculation. This function is different from `window-body-width' in
269 that it accounts for (i) continuation glyphs, (ii) the size of the
270 font, and (iii) the specified window.
272 ** New possible value for `system-type': nacl.
275 ** New variable `inhibit-message', when bound to non-nil, inhibits
276 `message' and related functions from displaying messages the Echo
277 Area. The output is still logged to the *Messages* buffer.
280 ** It is now safe for a mode that derives `tabulated-list-mode' to not
281 call `tabulated-list-init-header', in which case it will have no
285 ** `tabulated-list-print' takes a second optional argument, update,
286 which specifies an alternative printing method which is faster when
287 few or no entries have changed.
290 * Editing Changes in Emacs 25.1
292 ** Successive single-char deletions are collapsed in the undo-log just like
293 successive char insertions.
295 ** Unicode names entered via C-x 8 RET now use substring completion by default.
297 ** C-x 8 now has shorthands for these chars: ‐ ‑ ‒ – — ― ‘ ’ “ ” † ‡ • ′ ″
298 € № ← → ↔ − ≈ ≠ ≤ ≥. As before, you can type C-x 8 C-h to list shorthands.
300 ** New minor mode electric-quote-mode for quoting ‘like this’ and “like this”
301 as you type. See also the new variable ‘text-quoting-style’.
303 ** New minor mode global-eldoc-mode is enabled by default.
305 ** Emacs now supports "bracketed paste mode" when running on a terminal
306 that supports it. This facility allows Emacs to understand pasted
307 chunks of text as strings to be inserted, instead of interpreting each
308 character in the pasted text as actual user input. This results in a
309 paste experience similar to that under a window system, and significant
310 performance improvements when pasting large amounts of text.
312 ** Emacs now supports the latest version of the UBA.
313 The Emacs implementation of the Unicode Bidirectional Algorithm (UBA)
314 was updated to support all the latest additions and changes introduced
315 in Unicode Standard versions 6.3, 7.0, and the latest Unicode 8.0.
316 This includes full support for directional isolates and the
317 Bidirectional Parentheses Algorithm (BPA) specified by these Unicode
320 ** You can access `mouse-buffer-menu' (C-down-mouse-1) using C-f10.
323 ** New buffer-local `electric-pair-local-mode'.
326 * Changes in Specialized Modes and Packages in Emacs 25.1
328 ** New function `bookmark-set-no-overwrite' bound to C-x r M.
329 It raises an error if a bookmark of that name already exists,
330 unlike `bookmark-set' which silently updates an existing bookmark.
334 *** `json-pretty-print' and `json-pretty-print-buffer' now maintain
335 the ordering of object keys by default.
337 *** New commands `json-pretty-print-ordered' and
338 `json-pretty-print-buffer-ordered' pretty prints JSON objects with
339 object keys sorted alphabetically.
341 ** You can recompute the VC state of a file buffer with `M-x vc-refresh-state'
342 ** Prog mode has some support for multi-mode indentation.
343 See `prog-indentation-context' and `prog-widen'.
345 ** Prettify Symbols mode
346 *** Prettify Symbols mode supports custom composition predicates. By
347 overriding the default `prettify-symbols-compose-predicate', modes can
348 specify in which contexts a symbol map be composed to some unicode
349 character. `prettify-symbols-default-compose-p' is the default which
350 is suitable for most programming languages such as C or Lisp (but not
353 *** Symbols can be unprettified while point is inside them.
354 New variable `prettify-symbols-unprettify-at-point' configures this.
356 ** New `xterm-screen-extra-capabilities' config.
358 ** The `save-place' variable is replaced by a `save-place-mode'.
362 *** Hide message types by network or channel. `erc-hide-list' will
363 hide all messages of the specified type, where `erc-network-hide-list'
364 and `erc-channel-hide-list' will only hide the specified message types
365 for the respective specified targets.
368 *** `midnight-mode' is a proper minor mode.
369 *** clean-buffer-*-regexps can now specify buffers via predicate functions.
371 ** In xterms, killing text now also sets the CLIPBOARD/PRIMARY selection
372 in the surrounding GUI (using the OSC-52 escape sequence). This only works
373 if your xterm supports it and enables the `allowWindowOps' options (disabled
374 by default at least in Debian, for security reasons).
376 Similarly, you can yank the CLIPBOARD/PRIMARY selection (using the OSC-52
377 escape sequence) if your xterm has the feature enabled but for that you
378 additionally need to add `getSelection' to `xterm-extra-capabilities'.
380 ** xterm-mouse-mode now supports mouse-tracking (if your xterm supports it).
384 *** New "external" package status.
385 An external package is any installed package that's not built-in and
386 not from `package-user-dir', which usually means it's from an entry in
387 `package-directory-list'. They are treated much like built-in
388 packages, in that they cannot be deleted through the package menu and
389 are not considered for upgrades.
391 The effect, is that a user can manually place a specific version of a
392 package inside `package-directory-list' and the package menu will
395 *** If a package is available on multiple archives and one has higher
396 priority (as per `package-archive-priorities') only that one is
397 listed. This can be configured with `package-menu-hide-low-priority'.
399 *** `package-menu-toggle-hiding' now toggles the hiding of packages.
400 This includes the above-mentioned low-priority packages, as well as
401 available packages whose version is lower than the currently installed
402 version (which were previously impossible to display).
403 This allows users to downgrade a package if a lower version is
406 *** When filtering the package menu, keywords starting with "arc:" or
407 "status:" represent package archive or status, respectively, instead
410 *** Most functions which involve downloading information now take an
411 ASYNC argument. If it is non-nil, package.el performs the download(s)
414 *** New variable `package-menu-async' controls whether the
415 package-menu uses asynchronous downloads.
417 *** `package-install-from-buffer' and `package-install-file' work on directories.
418 This follows the same rules as installing from a .tar file, except the
419 -pkg file is optional.
421 *** Packages which are dependencies of other packages cannot be deleted.
422 The FORCE argument to `package-delete' overrides this.
424 *** New custom variable `package-selected-packages' tracks packages
425 which were installed by the user (as opposed to installed as
426 dependencies). This variable can also be manually customized.
428 *** New command `package-install-user-selected-packages' installs all
429 packages from `package-selected-packages' which are currently missing.
431 *** New command `package-autoremove' removes all packages which were
432 installed strictly as dependencies but are no longer needed.
436 When you invoke `shell' interactively, the *shell* buffer will now
437 display in a new window. However, you can customize this behavior via
438 the `display-buffer-alist' variable. For example, to get
439 the old behavior -- *shell* buffer displays in current window -- use
440 (add-to-list 'display-buffer-alist
441 '("^\\*shell\\*$" . (display-buffer-same-window))).
445 *** The `:protection' slot option is not obeyed any more.
447 *** The `newname' argument to constructors is optional&deprecated.
448 If you need your objects to be named, do it by inheriting from `eieio-named'.
450 *** The <class>-list-p and <class>-child-p functions are declared obsolete.
452 *** The <class> variables are declared obsolete.
454 *** The <initarg> variables are declared obsolete.
455 *** defgeneric and defmethod are declared obsolete.
457 *** `constructor' is now an obsolete alias for `make-instance'.
460 *** New command `ido-bury-buffer-at-head' bound to C-S-b
461 Bury the buffer at the head of `ido-matches', analogous to how C-k
462 kills the buffer at head.
463 *** A prefix argument to `ido-restrict-to-matches' will reverse its
464 meaning, and the list is restricted to those elements that do not
465 match the current input.
469 *** You can use <up> and <down> keys to move point in the multi-line
470 minibuffer just as in an ordinary buffer. Only when point moves over
471 the bottom/top of the minibuffer it goes to the next/previous history
472 element. The new commands bound to <up> and <down> in the minibuffer:
473 `next-line-or-history-element' and `previous-line-or-history-element'.
475 ** Search and Replace
477 *** Query-replace history is enhanced.
478 When query-replace reads the FROM string from the minibuffer, typing
479 `M-p' will now show previous replacements as "FROM SEP TO", where FROM
480 and TO are the original text and its replacement, and SEP is an arrow
481 string defined by the new variable `query-replace-from-to-separator'.
482 To select a prior replacement, type `M-p' until the desired
483 replacement appears in the minibuffer, and then exit the minibuffer by
488 *** If `quick-calc' is called with a prefix argument, insert the
489 result of the calculation into the current buffer.
492 ** In Edebug, you can now set the initial mode with C-x C-a C-m. With
493 this you can tell Edebug not to stop at the start of the first
494 instrumented function.
497 *** New minor mode `global-eldoc-mode'
498 *** `eldoc-documentation-function' now defaults to `ignore'
499 *** `describe-char-eldoc' displays information about character at point,
500 and can be used as a default value of `eldoc-documentation-function'. It is
501 useful when, for example, one needs to distinguish various spaces (e.g. ] [,
502 ] [, ] [, etc.) while using mono-spaced font.
507 *** HTML can now be rendered using variable-width fonts.
510 *** A new command `F' (`eww-toggle-fonts') can be used to toggle
511 whether to use variable-pitch fonts or not. The user can also
512 customize the `shr-use-fonts' variable.
515 *** A new command `R' (`eww-readable') will try do identify the main
516 textual parts of a web page and display only that, leaving menus and
517 the like off the page.
520 *** You can now use several eww buffers in parallel by renaming eww
521 buffers you want to keep separate.
524 *** Partial state of the eww buffers (the URIs and the titles of the
525 pages visited) is now preserved in the desktop file.
528 *** `eww-after-render-hook' is now called after eww has rendered
529 the data in the buffer.
532 *** The `eww-reload' command now takes a prefix to not reload via
533 the net, but just use the local copy of the HTML.
536 *** The DOM shr and eww uses has been changed to the general Emacs
537 xml.el/libxml2 DOM, and a new package dom.el has been added to
538 interact with this DOM. See the Emacs Lisp manual for interface
542 *** `mailcap-mime-data' is now consulted when displaying PDF files.
545 *** The new `S' command will list all eww buffers, and allow managing
549 *** https pages with valid certificates have headers marked in green, while
550 invalid certificates are marked in red.
554 *** text/html messages that contain inline image parts will be
555 transformed into multipart/related messages before sending.
558 *** New UPatterns `quote', `app', `cl-struct', and `eieio'.
559 *** New UPatterns can be defined with `pcase-defmacro'.
561 *** New vector QPattern.
564 *** Strings after `:documentation' are highlighted as docstrings.
567 *** Rectangle Mark mode can have corners past EOL or in the middle of a TAB.
568 *** C-x C-x in rectangle-mark-mode now cycles through the four corners.
569 *** `string-rectangle' provides on-the-fly preview of the result.
571 ** New font-lock functions font-lock-ensure and font-lock-flush, which
572 should be used instead of font-lock-fontify-buffer when called from Elisp.
574 ** Macro `minibuffer-with-setup-hook' takes (:append FUN) to mean
575 appending FUN to `minibuffer-setup-hook'.
578 *** New functions cl-fresh-line, cl-digit-char-p and cl-parse-integer.
580 ** Calendar and diary
583 *** The default `diary-file' is now located in .emacs.d.
586 *** New commands to insert diary entries with Chinese dates:
587 `diary-chinese-insert-anniversary-entry' `diary-chinese-insert-entry'
588 `diary-chinese-insert-monthly-entry', `diary-chinese-insert-yearly-entry'.
591 *** The calendar can now list and mark diary entries with Chinese dates.
592 See `diary-chinese-list-entries' and `diary-chinese-mark-entries'.
595 *** The option `calendar-mode-line-format' can now be nil,
596 which means to do nothing special with the mode line in calendars.
599 *** New option `calendar-weekend-days'.
600 The option customizes which day headers receive the
601 `calendar-weekend-header' face.
604 *** New optional args N and STRING for ‘holiday-greek-orthodox-easter’.
607 *** Many items obsolete since at least version 23.1 have been removed.
608 The majority were function/variable/face aliases, too numerous to list here.
611 **** Functions `calendar-one-frame-setup', `calendar-only-one-frame-setup',
612 `calendar-two-frame-setup', `european-calendar', `american-calendar'.
614 **** Hooks `cal-menu-load-hook', `cal-x-load-hook'.
616 **** Macro `calendar-for-loop'.
618 **** Variables `european-calendar-style', `diary-face', `hebrew-holidays-{1,4}'.
620 **** The nil and list forms of `diary-display-function'.
622 ** New ERT function `ert-summarize-tests-batch-and-exit'.
624 ** New js.el option `js-indent-first-init'.
627 ** `Info-fontify-maximum-menu-size' can be t for no limit.
630 ** `info-display-manual' can now be given a prefix argument which (any
631 non-nil value) directs the command to limit the completion
632 alternatives to currently visited manuals.
635 ** ntlm.el has support for NTLM2.
639 *** The Rmail commands d, C-d and u take optional repeat counts to delete or
640 undelete multiple messages.
642 *** Rmail can now render HTML mail messages if your Emacs was built with
643 libxml2 or if you have the Lynx browser installed. By default, Rmail
644 will display the HTML version of a mail message that has both HTML and
645 plain text parts, if display of HTML email is possible; customize the
646 `rmail-mime-prefer-html' option to `nil' if you don't want that.
649 *** In the commands that make summaries by subject, recipients, or senders,
650 you can no longer use commas to separate regular expressions.
652 ** SES now supports local printer functions; see `ses-define-local-printer'.
655 *** In sh-mode you can now use `sh-shell' as a file-local variable to
656 specify the type of shell in use (bash, csh, etc).
658 *** New value `always' for sh-indent-after-continuation.
659 This provides old-style ("dumb") indentation of continued lines.
663 *** Fatal TLS errors are now silent by default.
667 *** The URL package accepts now the protocols "ssh", "scp" and "rsync".
668 When `url-handler-mode' is enabled, file operations for these
669 protocols as well as for "telnet" and "ftp" are passed to Tramp.
671 *** The URL package allows customizing the `url-user-agent' string.
672 The new `url-user-agent' variable can be customized to be a string or
675 *** The new interface variable `url-request-noninteractive' can be used
676 to specify that we're running in a noninteractive context, and that
677 we should not be queried about things like TLS certificate validity.
679 *** If URL is used with a https connection, the first callback argument
680 plist will contain a :peer element that has the output of
681 `gnutls-peer-status' (if Emacs is built with GnuTLS support).
686 *** New connection method "afp", which allows to access Mac OS X
687 volumes via the Apple Filing Protocol.
690 *** New connection method "nc", which allows to access dumb busyboxes.
693 *** Method-specific parameters can be overwritten now with variable
694 `tramp-connection-properties'.
697 *** Handler for `file-notify-valid-p' for remote machines that support
698 filesystem notifications.
702 *** New user variable `sql-default-directory' enables remote
703 connections using Tramp.
705 *** New command `sql-send-line-and-next' sends the current line to the
706 interactive buffer and advances to the next line, skipping whitespace
709 *** Add support for Vertica SQL.
711 ** VC and related modes
713 *** Basic push support, via `vc-push', bound to `C-x v P'.
714 Implemented for Bzr, Git, Hg. As part of this change, the pre-existing
715 (undocumented) command vc-hg-push now behaves slightly differently.
717 *** The new command vc-region-history shows the log+diff of the active region.
719 *** New option `vc-annotate-background-mode' controls whether
720 the color range from `vc-annotate-color-map' is applied to the
721 background or to the foreground.
723 *** `compare-windows' now compares text with the most recently used window
724 instead of the next window. The new option `compare-windows-get-window-function'
725 allows to customize this.
727 *** Two new faces `compare-windows-removed' and `compare-windows-added'
728 replace the obsolete face `compare-windows'.
731 *** `log-edit-insert-changelog' converts "(tiny change)" to
732 "Copyright-paperwork-exempt: yes". Set `log-edit-rewrite-tiny-change'
735 ** VHDL mode supports VHDL'08.
737 ** Calculator: decimal display mode uses "," groups, so it's more
738 fitting for use in money calculations; factorial works with
741 ** HideIfDef mode now support full C/C++ expressions, argumented macro expansions,
742 interactive macro evaluation and automatic scanning of #defined symbols.
744 *** New custom variable `hide-ifdef-header-regexp' to define C/C++ header file
745 name patterns. Default case-insensitive .h, .hh, .hpp, .hxx, and .h++.
746 *** New custom variable `hide-ifdef-expand-reinclusion-protection' to prevent
747 reinclusion protected header files from being fully hidden.
748 *** New custom variable `hide-ifdef-exclude-define-regexp' to define symbol
749 name patterns (e.g. all "FOR_DOXYGEN_ONLY_*") to be excluded.
753 *** New custom variable `tex-print-file-extension' to help users who
754 use PDF instead of DVI.
756 *** TeX mode now supports Prettify Symbols mode. When enabling
757 `prettify-symbols-mode' in a tex-mode buffer, \alpha ... \omega, and
758 many other math macros are displayed using unicode characters.
760 ** whitespace-mode: new 'big-indent style highlighting too much indentation.
761 By default, 32 spaces and four TABs are considered to be too much but
762 `whitespace-big-indent-regexp' can be configured to change that.
764 ** tildify: `tildify-space-string', `tildify-pattern', and
765 `tildify-foreach-region-function' variables added making
766 `tildify-string-alist', `tildify-pattern-alist', and
767 `tildify-ignored-environments-alist' variables (as well as a few
768 helper functions) obsolete.
771 The new package provides generic framework and new commands to find
772 and move to definitions, as well as pop back to the original location.
775 `xref-find-definitions' replaces `find-tag' and provides an interface
776 to pick one destination among several. Hence, `tags-loop-continue' is
777 unbound. `xref-pop-marker-stack' replaces `pop-tag-mark', but uses an
778 easier binding, which is now unoccupied (`M-,').
779 `xref-find-definitions-other-window' replaces `find-tag-other-window'.
780 `xref-find-definitions-other-frame' replaces `find-tag-other-frame'.
781 `xref-find-apropos' replaces `find-tag-regexp'.
784 `find-tag-marker-ring-length' is now an obsolete alias for
785 `xref-marker-ring-length'. `find-tag-marker-ring' is now an obsolete
786 alias for a private variable. `xref-push-marker-stack' and
787 `xref-pop-marker-stack' should be used to mutate it instead.
790 As a result of the above, these commands are now obsolete:
791 `find-tag-other-window', `find-tag-other-frame', `find-tag-regexp',
792 `tags-apropos' and `tags-loop-continue'.
795 EUDC's LDAP backend has been improved.
797 *** EUDC supports LDAP-over-SSL URLs (ldaps://).
799 *** EUDC passes LDAP passwords through a pipe to the ldapsearch
800 subprocess instead of on the command line.
802 *** EUDC handles LDAP wildcards automatically so the user shouldn't
803 need to configure this manually anymore.
805 *** The LDAP configuration section of EUDC's manual has been
808 There have also been customization changes.
810 *** New custom variable `eudc-server-hotlist' to allow specifying
811 multiple EUDC servers in init file.
813 *** Custom variable `eudc-inline-query-format' defaults to completing
814 on email and firstname instead of surname.
816 *** Custom variable `eudc-expansion-overwrites-query' defaults to nil
817 to avoid interfering with the kill ring.
819 *** Custom variable `eudc-inline-expansion-format' defaults to
820 "Firstname Surname <mail-address>".
822 *** Custom variable `eudc-options-file' defaults to
823 "~/.emacs.d/eudc-options".
825 *** New custom variable `ldap-ldapsearch-password-prompt-regexp' to
826 allow overriding the regular expression that recognizes the ldapsearch
827 command line's password prompt.
832 *** The new built-in command `clear' can scroll window contents out of sight.
833 If provided with an optional non-nil argument, the scrollback contents will be cleared.
835 *** New buffer syntax '#<buffer-name>', which is equivalent to
836 '#<buffer buffer-name>'. This shorthand makes interacting with
837 buffers from eshell more convenient. Custom variable
838 `eshell-buffer-shorthand', which has been broken for a while, has been
841 *** By default, eshell "visual" program buffers (created by
842 `eshell-visual-commands' and similar custom vars) are no longer killed
843 when their processes die. This fixes issues with short-lived commands
844 and makes visual programs more useful in general. For example, if
845 "git log" is a visual command, it will always show the visual command
846 buffer, even if the "git log" process dies. For the old behavior,
847 make the new option `eshell-destroy-buffer-when-process-dies' non-nil.
851 *** Support for the Conkeror web browser.
854 *** Support for several ancient browsers is now officially obsolete.
857 ** tar-mode: new `tar-new-entry' command, allowing for new members to
858 be added to the archive.
861 ** Autorevert: dired buffers are also auto-reverted via file
862 notifications, if Emacs is compiled with file notification support.
864 ** File Notifications
867 *** The new event `stopped' signals, that a file notification watch is
868 not active any longer.
871 *** The new function `file-notify-valid-p' checks, whether a file
872 notification descriptor still corresponds to an activate watch.
877 *** The command `dired-do-compress' bound to `Z' now can compress
878 directories and decompress zip files.
881 *** New command `dired-do-compress-to' bound to `c' can be used to
882 compress many marked files into a single named archive. The
883 compression command is determined from the new
884 `dired-compress-files-alist' variable.
891 *** landmark.el (moved to elpa.gnu.org)
894 * New Modes and Packages in Emacs 25.1
896 ** pinentry.el allows GnuPG passphrase to be prompted through the
897 minibuffer instead of a graphical dialog, depending on whether the gpg
898 command is called from Emacs (i.e., INSIDE_EMACS environment variable
899 is set). This feature requires newer versions of GnuPG (2.1.5 or
900 later) and Pinentry (0.9.5 or later).
902 ** cl-generic.el provides CLOS-style multiple-dispatch generic functions.
904 ** scss-mode (a minor variant of css-mode)
906 ** let-alist is a new macro (and a package) that allows one to easily
907 let-bind the values stored in an alist.
909 ** `tildify-mode' allows to automatically insert hard spaces as one
910 types the text. Breaking line after a single-character words is
911 forbidden by Czech and Polish typography (and may be discouraged in
912 other languages), so `auto-tildify-mode' makes it easier to create
913 a typographically-correct documents.
915 ** The `seq' library adds sequence manipulation functions and macros
916 that complement basic functions provided by subr.el. All functions
917 are prefixed with `seq-' and work on lists, strings and vectors.
919 ** The `map' library provides map-manipulation functions that work on
920 alists, hash-table and arrays. All functions are prefixed with
923 ** The `thunk' library provides functions and macros to control the
926 ** js-jsx-mode (a minor variant of js-mode) provides indentation
927 support for JSX, an XML-like syntax extension to ECMAScript.
930 * Incompatible Lisp Changes in Emacs 25.1
932 ** `syntax-begin-function' is declared obsolete.
933 Removed font-lock-beginning-of-syntax-function and the SYNTAX-BEGIN
934 slot in font-lock-defaults.
937 ** `package-initialize' now sets `package-enable-at-startup' to nil if
938 called during startup. Users who call this function in their init
939 file and still expect it to be run after startup should set
940 `package-enable-at-startup' to t after the call to
941 `package-initialize'.
943 ** `:global' minor mode use `setq-default' rather than `setq'.
944 This means that you can't use `make-local-variable' and expect them to
945 "magically" become buffer-local.
947 ** `inhibit-point-motion-hooks' now defaults to t and is obsolete.
950 ** `track-mouse' no longer freezes the shape of the mouse pointer.
951 The `track-mouse' form no longer refrains from changing the shape of
952 the mouse pointer for the entire time the body of that form is
953 executed. Lisp programs that use `track-mouse' for dragging across
954 large portions of the Emacs display, and want to avoid changes in the
955 pointer shape during dragging, should bind the variable `track-mouse'
956 to the special value `dragging' in the body of the form.
958 ** The optional `predicate' argument of `lisp-complete-symbol' no longer
959 has any effect. (This change was made in Emacs 24.4 but was not
960 advertised at the time.)
962 ** `indirect-function' does not signal `void-function' any more.
963 This is mostly a bug-fix, since this change was missed back in 24.4 when
964 symbol-function was changed not to signal `void-function' any more.
965 *** As a consequence, the second arg of `indirect-function' is now obsolete.
967 ** Comint, term, and compile do not set the EMACS env var any more.
968 Use the INSIDE_EMACS environment variable instead.
970 ** `save-excursion' does not save&restore the mark any more.
972 ** read-buffer-function can now be called with a 4th argument (`predicate').
974 ** completion-table-dynamic stays in the minibuffer.
975 If you want the old behavior of calling the function in the buffer
976 from which the minibuffer was entered, call it with the new argument
979 ** window-configurations no longer record the buffers' marks.
981 ** inhibit-modification-hooks now also inhibits lock-file checks, as well as
982 active region handling.
984 ** deactivate-mark is now buffer-local.
986 ** `cl-the' now asserts that its argument is of the given type.
988 ** `process-running-child-p` may now return a numeric process
989 group ID instead of `t'.
992 ** Mouse click events on mode line or header line no longer include
993 any reference to a buffer position. The 6th member of the mouse
994 position list returned for such events is now nil.
996 ** Menu items in keymaps do not support the "key shortcut cache" any more.
997 These slots used to hold key-shortcut data, but have been obsolete since
1000 ** Emacs no longer downcases the first letter of a system diagnostic
1001 when signaling a file error. For example, it now reports "Permission
1002 denied" instead of "permission denied". The old behavior was problematic
1003 in languages like German where downcasing rules depend on grammar.
1006 ** New variable ‘text-quoting-style’ to control how Emacs translates quotes.
1007 Set it to ‘curve’ for curved single quotes ‘like this’, to ‘straight’
1008 for straight apostrophes 'like this', and to ‘grave’ for grave accent
1009 and apostrophe `like this'. The default value nil acts like ‘curve’
1010 if curved single quotes are displayable, and like ‘grave’ otherwise.
1011 The new variable affects display of diagnostics and help, but not of info.
1014 ** substitute-command-keys now replaces quotes.
1015 That is, it converts documentation strings’ quoting style as per the
1016 value of ‘text-quoting-style’. Doc strings in source code can use
1017 either curved single quotes or grave accents and apostrophes. As
1018 before, characters preceded by \= are output as-is.
1021 ** Message-issuing functions ‘error’, ‘message’, etc. now convert quotes.
1022 They use the new ‘format-message’ function instead of plain ‘format’,
1023 so that they now follow user preference as per ‘text-quoting-style’
1024 when processing curved single quotes, grave accents, and apostrophes
1025 in their format argument.
1028 ** The character classes [:alpha:] and [:alnum:] in regular expressions
1029 now match multibyte characters using Unicode character properties.
1030 If you want the old behavior where they matched any character with
1031 word syntax, use `\sw' instead.
1034 ** The character classes [:graph:] and [:print:] in regular expressions
1035 no longer match every multibyte character. Instead, Emacs now
1036 consults the Unicode character properties to determine which
1037 characters are graphic or printable. In particular, surrogates and
1038 unassigned codepoints are now rejected. If you want the old behavior,
1039 use [:multibyte:] instead.
1042 ** The `diff' command uses the unified format now. To restore the old
1043 behavior, set `diff-switches' to `-c'.
1045 ** `grep-template' and `grep-find-template' values don't include the
1046 --color argument anymore. It's added at the <C> place holder position
1047 dynamically. Any third-party code that changes these templates should
1048 be updated accordingly.
1051 ** ‘(/ N)’ is now equivalent to ‘(/ 1 N)’ rather than to ‘(/ N 1)’.
1052 The new behavior is compatible with Common Lisp and with XEmacs.
1053 This change does not affect Lisp code intended to be portable to
1054 Emacs 24.2 and earlier, which did not support unary ‘/’.
1057 ** The `default-directory' value doesn't have to end slash. To make
1058 that happen, `unhandled-file-name-directory' now defaults to calling
1059 `file-name-as-directory'.
1062 * Lisp Changes in Emacs 25.1
1064 ** syntax-propertize is now automatically called on-demand during forward
1065 parsing functions like `forward-sexp'.
1067 ** New hooks prefix-command-echo-keystrokes-functions and
1068 prefix-command-preserve-state-hook, to allow the definition of prefix
1069 commands other than the predefined C-u.
1071 ** New functions `filepos-to-bufferpos' and `bufferpos-to-filepos'.
1073 ** The default value of `load-read-function' is now `read'.
1075 ** New hook `pre-redisplay-functions', a bit easier to use than pre-redisplay-function.
1077 ** The second arg of `looking-back' should always be provided explicitly.
1079 ** Obsolete text properties `intangible', `point-entered', and `point-left'.
1080 Replaced by properties `cursor-intangible' and `cursor-sensor-functions',
1081 implemented by the new `cursor-intangible-mode' and
1082 `cursor-sensor-mode' minor modes.
1084 ** New process type `pipe', which can be used in combination with the
1085 `:stderr' keyword of make-process to handle standard error output
1088 ** New function `make-process' provides an alternative interface to
1089 `start-process'. It allows programs to set process parameters such as
1090 process filter, sentinel, etc., through keyword arguments (similar to
1091 `make-network-process').
1093 ** `read-buffer' takes a new `predicate' argument.
1095 ** Emacs Lisp now supports generators.
1097 ** New finalizer facility for running code when objects
1100 ** lexical closures can use (:documentation <form>) to build their docstring.
1101 It should be placed right where the docstring would be, and <form> is then
1102 evaluated (and should return a string) when the closure is built.
1104 ** define-inline provides a new way to define inlinable functions.
1106 ** New function `macroexpand-1' to perform a single step of macroexpansion.
1108 ** Some "x-*" were obsoleted:
1109 *** x-select-text is renamed gui-select-text.
1110 *** x-selection-value is renamed gui-selection-value.
1111 *** x-get-selection is renamed gui-get-selection.
1112 *** x-get-clipboard and x-clipboard-yank are marked obsolete.
1113 *** x-get-selection-value is renamed to gui-get-primary-selection.
1114 *** x-set-selection is renamed to gui-set-selection
1116 ** New function `string-greaterp', which return the opposite result of
1119 ** New function `alist-get', which is also a valid place (aka lvalue).
1121 ** New function `funcall-interactively', which works like `funcall'
1122 but makes `called-interactively-p' treat the function as (you guessed it)
1123 called interactively.
1125 ** New function `function-put' to use instead of `put' for function properties.
1128 ** New properties that can be specified with `declare':
1129 *** (interactive-only INSTEAD), says to use INSTEAD for non-interactive use.
1130 *** (pure VAL), if VAL is non-nil, indicates the function is pure.
1131 *** (side-effect-free VAL), if VAL is non-nil, indicates the function does not
1135 ** New macro `with-file-modes', for evaluating expressions with default file
1136 permissions set to temporary values (e.g., for creating private files).
1138 ** You can access the slots of structures using `cl-struct-slot-value'.
1140 ** Function `sort' can deal with vectors.
1142 ** Function `system-name' now returns an updated value if the current
1143 system's name has changed or if the Emacs process has changed systems,
1144 and to avoid long waits it no longer consults DNS to canonicalize the
1145 name. The variable `system-name' is now obsolete.
1148 ** Function `write-region' no longer outputs "Wrote FILE" in batch mode.
1150 ** If `pwd' is called with a prefix argument, insert the current default
1154 ** New utilities in subr-x.el:
1155 *** New macros `if-let' and `when-let' allow defining bindings and to
1156 execute code depending whether all values are true.
1157 *** New macros `thread-first' and `thread-last' allow threading a form
1158 as the first or last argument of subsequent forms.
1161 ** Documentation strings now support quoting with curved single quotes
1162 ‘like-this’ in addition to the old style with grave accent and
1163 apostrophe `like-this'. The new style looks better on today's displays.
1164 In the new Electric Quote mode, you can enter curved single quotes
1165 into documentation by typing ` and '. Outside Electric Quote mode,
1166 you can enter them by typing ‘C-x 8 [’ and ‘C-x 8 ]’, or (if your Alt
1167 key works) by typing ‘A-[’ and ‘A-]’. As described above under
1168 ‘text-quoting-style’, the user can specify how to display doc string
1172 ** New function ‘format-message’ is like ‘format’ and also converts
1173 curved single quotes, grave accents and apostrophes as per
1174 ‘text-quoting-style’.
1177 ** show-help-function's arg is converted via substitute-command-keys
1178 before being passed to the function. Help strings, help-echo
1179 properties, etc. can therefore contain command key escapes and
1183 ** Time-related changes:
1185 *** Time conversion functions now accept an optional ZONE argument
1186 that specifies the time zone rules for conversion. ZONE is omitted or
1187 nil for Emacs local time, t for Universal Time, ‘wall’ for system wall
1188 clock time, or a string as in ‘set-time-zone-rule’ for a time zone
1189 rule. The affected functions are ‘current-time-string’,
1190 ‘current-time-zone’, ‘decode-time’, and ‘format-time-string’. The
1191 function ‘encode-time’, which already accepted a simple time zone rule
1192 argument, has been extended to accept all the new forms.
1194 *** Time-related functions now consistently accept numbers
1195 (representing seconds since the epoch) and nil (representing the
1196 current time) as well as the usual list-of-integer representation.
1197 Affected functions include `current-time-string', `current-time-zone',
1198 `decode-time', `float-time', `format-time-string', `seconds-to-time',
1199 `time-add', `time-less-p', `time-subtract', `time-to-day-in-year',
1200 `time-to-days', and `time-to-seconds'.
1202 *** The `encode-time-value' and `with-decoded-time-value' macros have
1205 *** `calendar-next-time-zone-transition', `time-add', and
1206 `time-subtract' no longer return time values in the obsolete and
1207 undocumented integer-pair format. Instead, they return a list of two
1211 ** New function `set-binary-mode' allows to switch a standard stream
1212 of the Emacs process to binary I/O mode.
1214 ** ASCII approximations to curved quotes are put in standard-display-table
1215 if the terminal cannot display curved quotes.
1217 ** Standard output and error streams now transliterate characters via
1218 standard-display-table, and encode output using locale-coding-system.
1220 ** Miscellaneous name change
1222 For consistency with the usual Emacs spelling, the Lisp variable
1223 `hfy-optimisations' has been renamed to `hfy-optimizations'.
1224 The old name should still work, as an obsolescent alias.
1227 * Changes in Frames and Windows Code in Emacs 25.1
1230 ** Emacs can now draw horizontal scroll bars on some platforms that
1231 provide toolkit scroll bars, namely Gtk+, Lucid, Motif and Windows.
1232 Horizontal scroll bars are turned off by default.
1233 *** New function `horizontal-scroll-bars-available-p' telling whether
1234 horizontal scroll bars are available on the underlying system.
1235 *** New mode `horizontal-scroll-bar-mode' to toggle horizontal scroll
1236 bars on all existing and future frames.
1237 *** New function `toggle-horizontal-scroll-bar' to toggle horizontal
1238 scroll bars on the selected frame.
1239 *** New frame parameters `horizontal-scroll-bars' and
1240 `scroll-bar-height' to set horizontal scroll bars and their height
1241 for individual frames and in `default-frame-alist'.
1242 *** New functions `frame-scroll-bar-height' and
1243 `window-scroll-bar-height' return the height of horizontal scroll
1244 bars on a specific frame or window.
1245 *** `set-window-scroll-bars' now accepts five parameters where the last
1246 two specify height and type of the window's horizontal scroll bar.
1247 *** `window-scroll-bars' now returns type and sizes of horizontal scroll
1249 *** New buffer-local variables `horizontal-scroll-bar' and
1250 `scroll-bar-height'.
1253 ** New functions `frame-geometry' and `frame-edges' give access to a
1257 ** New functions `mouse-absolute-pixel-position' and
1258 `set-mouse-absolute-pixel-position' get/set screen coordinates of the
1262 ** The function `window-edges' now accepts three additional arguments to
1263 retrieve body, absolute and pixel edges of the window.
1266 ** The functions `window-inside-edges', `window-inside-pixel-edges' and
1267 `window-inside-absolute-pixel-edges' have been renamed to respectively
1268 `window-body-edges', `window-body-pixel-edges' and
1269 `window-absolute-body-pixel-edges'. The old names are kept as aliases.
1272 ** New function `window-absolute-pixel-position' to get the screen
1273 coordinates of a visible buffer position.
1276 ** The height of a frame's menu and tool bar are no longer counted in the
1277 frame's text height. This means that the text height stands only for
1278 the height of the frame's root window plus that of the echo area (if
1279 present). This was already the behavior for frames with external tool
1280 and menu bars (like in the Gtk builds) but has now been extended to all
1284 ** Frames now do not necessarily preserve the number of columns or lines
1285 they display when setting default font, menu bar, fringe width, or
1286 scroll bars. In particular, maximized and fullscreen frames are
1287 conceptually never resized if such settings change. For fullheight and
1288 fullwidth frames, the behavior may depend on the toolkit used.
1289 *** New option `frame-inhibit-implied-resize' if non-nil, means that
1290 setting default font, menu bar, fringe width, or scroll bars of a
1291 specific frame does not resize that frame in order to preserve the
1292 number of columns or lines it displays.
1295 ** New function `window-preserve-size' allows to preserve the size of
1296 windows without "fixing" it. It's supported by `fit-window-to-buffer',
1297 `temp-buffer-resize-mode' and `display-buffer'.
1300 ** New minor mode `window-divider-mode' and options
1301 `window-divider-default-places', `window-divider-default-bottom-width'
1302 and `window-divider-default-right-width'.
1305 ** New option `switch-to-buffer-in-dedicated-window' allows to customize
1306 how `switch-to-buffer' proceeds interactively when the selected window
1307 is strongly dedicated to its buffer.
1310 ** The option `even-window-heights' has been renamed to
1311 `even-window-sizes' and now handles window widths as well.
1313 ** Tearoff menus and detachable toolbars for Gtk+ has been removed.
1314 Those features have been deprecated in Gtk+ for a long time.
1318 *** etags no longer qualifies class members by default.
1319 By default, `etags' will not qualify class members for C-like
1320 object-oriented languages with their class names and namespaces, and
1321 will remove qualifications used explicitly in the code from the tag
1322 names it puts in TAGS files. This is so the etags.el back-end for
1323 `xref-find-definitions' is more accurate and produces less false
1326 Use --class-qualify (-Q) if you want the old default behavior of
1327 qualifying class members in C++, Java, and Objective C. Note that
1328 using -Q might make some class members become "unknown" to `M-.'
1329 (`xref-find-definitions'); if so, you can use `C-u M-.' to specify the
1330 qualified names by hand.
1333 * Changes in Emacs 25.1 on Non-Free Operating Systems
1336 ** MS-Windows specific Emacs build scripts are no longer in the distribution
1337 This includes the makefile.w32-in files in various subdirectories, and
1338 the support files. The file nt/configure.bat now just tells the user
1339 to use the procedure described in nt/INSTALL, by running the Posix
1340 `configure' script in the top-level directory.
1343 ** Building Emacs for MS-Windows requires at least Windows XP
1344 or Windows Server 2003. The built binaries still run on all versions
1345 of Windows starting with Windows 9X.
1348 ** Emacs running on MS-Windows now supports the daemon mode.
1350 ** The byte counts in etags-generated TAGS files are now the same on
1351 MS-Windows as they are on other platforms.
1354 ** On OS X, configure creates a Cocoa ("Nextstep") build by default.
1355 Pass '--without-ns' to configure to create an X11 build, the old default.
1357 ** OS X 10.5 or older is no longer supported.
1359 ** OS X on PowerPC is no longer supported.
1362 ** The new function 'w32-application-type' returns the type of an
1363 MS-Windows application given the name of its executable program file.
