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 25.2
28 ** 'configure' detects the kqueue file notification library on *BSD
29 and Mac OS X machines.
32 * Changes in Specialized Modes and Packages in Emacs 25.2
36 *** The kqueue library is integrated for *BSD and Mac OS X machines.
39 * Installation Changes in Emacs 25.1
42 ** Building Emacs now requires C99 or later.
44 ** Building Emacs now requires GNU make, version 3.81 or later.
46 ** New configure option --with-cairo.
47 Maybe add text based on http://lists.gnu.org/archive/html/emacs-devel/2015-05/msg00689.html
49 ** By default, Emacs no longer works on IRIX. We expect that Emacs
50 users are not affected by this, as SGI stopped supporting IRIX in
51 December 2013. If you are affected, please send a bug report. You
52 should be able to work around the problem either by porting the Emacs
53 undumping code to GCC under IRIX, or by configuring --with-wide-int,
54 or by sticking with Emacs 24.4.
56 ** The Emacs garbage collector assumes GC_MARK_STACK == GC_MAKE_GCPROS_NOOPS.
57 The GC_MAKE_GCPROS_NOOPS stack-marking variant has been the default
58 since Emacs 24.4, and the other variants were undocumented and were
59 obstacles to maintenance and development. GC_MARK_STACK and its
60 related symbols have been removed from the C internals.
62 ** 'configure' now prefers gnustep-config when configuring GNUstep.
63 If gnustep-config is not available, the old heuristics are used.
66 ** 'configure' now prefers inotify to gfile for file notification,
67 unless gfile is explicitly requested via --with-file-notification='gfile'.
70 ** The configure option '--with-pkg-config-prog' has been removed.
71 Use './configure PKG_CONFIG=/full/name/of/pkg-config' if you need to.
74 ** The configure option '--with-mmdf' has been removed.
75 It was no longer useful, as it relied on libraries that are no longer
76 supported, and its presence led to confusion during configuration.
77 This affects only the 'movemail' utility; Emacs itself can still
78 process MMDF-format files as before.
80 ** The configure option '--enable-silent-rules' is now the default,
81 and silent rules are now quieter. To get the old behavior where
82 'make' chatters a lot, configure with '--disable-silent-rules' or
83 build with 'make V=1'.
86 ** The configure option '--with-gameuser' now allows to specify a
87 group instead of a user if its argument is prefixed by ':' (a colon).
88 This will cause the game score files in ${localstatedir}/games/emacs
89 to be owned by that group, and the helper program for updating them to
90 be installed setgid. The option now defaults to the 'games' group.
93 ** The `grep-changelog' script (and its manual page) are no longer included.
94 It has no particular connection to Emacs and has not changed in years,
95 so if you want to use it, you can always take a copy from an older Emacs.
97 ** Emacs 25 comes with a new set of icons.
98 Various resolutions are available as etc/images/icons/hicolor/*/apps/emacs.png.
99 The old Emacs logo icons are available as `emacs23.png' in the same location.
102 * Startup Changes in Emacs 25.1
105 ** When Emacs is given a file as a command line argument and
106 `initial-buffer-choice' is non-nil, display both the file and
107 `initial-buffer-choice'. When Emacs is given more than one file and
108 `initial-buffer-choice' is non-nil, show `initial-buffer-choice'
109 and *Buffer List*. This makes Emacs convenient to use from the
110 command line when `initial-buffer-choice' is non-nil.
113 ** The value of ‘initial-scratch-message’ is now treated as a doc string
114 and can contain escape sequences for command keys, quotes, and the like.
117 * Changes in Emacs 25.1
119 ** Any file of the form .dir-locals*.el is now considered a dir-local
120 file, and multiple can be used in the same directory. See the
121 variable `dir-locals-file' for more information.
122 ** `xref-find-definitions' and `describe-function' now display
123 information about mode local overrides (defined by
124 cedet/mode-local.el `define-overloadable-function' and
125 `define-mode-local-overrides').
127 ** New `display-buffer' action function `display-buffer-use-some-frame'
128 This displays the buffer in an existing frame other than the current
129 frame, and allows the caller to specify a frame predicate to exclude
132 ** New doc command `describe-symbol'. Works for functions, vars, faces, etc...
134 ** New user option `search-default-regexp-mode' specifies the default mode for isearch
136 ** `isearch' and `query-replace' now perform character folding in matches.
137 This is analogous to case-folding, but applies between Unicode
138 characters and their ASCII counterparts. This means many characters
139 will match entire groups of characters.
141 For instance, the " will match all variants of unicode double quotes
142 (like “ and ”), and the letter a will match all of its accented
143 cousins, even those composed of multiple characters, as well as many
144 other symbols like ℀, ℁, ⒜, and ⓐ.
146 ** New function `character-fold-to-regexp' can be used
147 by searching commands to produce a regexp matching anything that
148 character-folds into STRING.
150 ** New command `checkdoc-package-keywords' checks if the
151 current package keywords are recognized. Set the new option
152 `checkdoc-package-keywords-flag' to non-nil to make
153 `checkdoc-current-buffer' call this function automatically.
155 ** New function `checkdoc-file' checks for style errors.
156 It's meant for use together with `compile':
157 emacs -batch --eval "(checkdoc-file \"subr.el\")"
159 ** New command `comment-line' bound to `C-x C-;'.
161 ** New function `custom-prompt-customize-unsaved-options' checks for
162 unsaved customizations and prompts user to customize (if found).
165 ** Network security (TLS/SSL certificate validity and the like) is
166 added via the new Network Security Manager (NSM) and controlled via
167 the `network-security-level' variable.
169 ** C-h l now also lists the commands that were run.
172 ** The new M-s M-w key binding uses eww to search the web for the
175 ** M-x suggests shorthands and ignores obsolete commands for completion.
176 ** x-select-enable-clipboard is renamed select-enable-clipboard.
177 x-select-enable-primary and renamed select-enable-primary.
178 Additionally they both now apply to all systems (OSX, GNUstep, Windows, you
179 name it), with the proviso that on some systems (e.g. Windows)
180 select-enable-primary is ineffective since the system doesn't
181 have the equivalent of a primary selection.
184 ** terpri gets an optional arg ENSURE to conditionally output a newline.
187 ** New macro `define-advice'.
189 ** `insert-register' now leaves point after the inserted text
190 when called interactively. A prefix argument toggles this behavior.
192 ** New var `truncate-string-ellipsis' to choose how to indicate truncation.
195 ** The new variable `term-file-aliases' replaces some files from lisp/term.
196 The function `tty-run-terminal-initialization' consults this variable
197 when deciding what terminal-specific initialization code to run.
200 ** New variable `system-configuration-features', listing some of the
201 main features that Emacs was compiled with. This is mainly intended
202 for use in Emacs bug reports.
205 ** A password is now hidden also when typed in batch mode. Another
206 hiding character but the default `.' can be used by let-binding the
207 variable `read-hide-char'.
209 ** The new functions `string-collate-lessp' and `string-collate-equalp'
210 preserve the collation order as defined by the system's locale(1)
211 environment. For the time being this is implemented for modern POSIX
212 systems and for MS-Windows, for other systems they fall back to their
213 counterparts `string-lessp' and `string-equal'.
215 *** The ls-lisp package uses `string-collate-lessp' to sort file names.
216 If you want the old, locale-independent sorting, customize the new
217 option `ls-lisp-use-string-collate' to a nil value.
219 *** The MS-Windows specific variable `w32-collate-ignore-punctuation',
220 if set to a non-nil value, causes the above 2 functions to ignore
221 symbol and punctuation characters when collating strings. This
222 emulates the behavior of modern Posix platforms when the locale's
223 codeset is "UTF-8" (as in "en_US.UTF-8"). This is needed because
224 MS-Windows doesn't support UTF-8 as codeset in its locales.
227 ** The new function `bidi-find-overridden-directionality' allows to
228 find characters whose directionality was, perhaps maliciously,
229 overridden by directional override control characters. Lisp programs
230 can use this to detect potential phishing of URLs and other links that
231 exploits bidirectional display reordering.
234 ** The new function `buffer-substring-with-bidi-context' allows to
235 copy a portion of a buffer into a different location while preserving
236 the visual appearance both of the copied text and the text at
237 destination, even when the copied text includes mixed bidirectional
238 text and directional control characters.
240 ** New variable `ns-use-fullscreen-animation' controls animation for
241 non-native NS fullscreen. The default is nil. Set to t to enable
242 animation when entering and leaving fullscreen. For native OSX fullscreen
245 ** A new text property `inhibit-read-only' can be used in read-only
246 buffers to allow certain parts of the text to be writable.
248 ** A new function `directory-files-recursively' returns all matching
249 files (recursively) under a directory.
251 ** The new function `directory-name-p' can be used to check whether a file
252 name (as returned from, for instance, `file-name-all-completions' is
253 a directory file name. It returns non-nil if the last character in
254 the name is a forward slash.
257 ** New variable `fast-but-imprecise-scrolling' inhibits
258 fontification during full screen scrolling operations, giving less
259 hesitant operation during auto-repeat of C-v, M-v at the cost of
260 possible inaccuracies in the end position.
262 ** The function `font-info' now returns more details about a font.
263 In particular, it now returns the average width of the font's
264 characters, which can be used for geometry-related calculations.
266 ** A new function `default-font-width' returns the average width of a
267 character in the current buffer's default font. If the default face
268 is remapped (see `face-remapping-alist'), the value for the remapped
269 face is returned. This function complements the existing function
270 `default-font-height'.
272 ** New functions `window-font-height' and `window-font-width' return
273 the height and average width of characters in a specified face and
274 window. If FACE is remapped (see `face-remapping-alist'), the
275 function returns the information for the remapped face.
277 ** A new function `window-max-chars-per-line' returns the maximal
278 number of characters that can be displayed on one line. If a face
279 and/or window are provided, these values are used for the
280 calculation. This function is different from `window-body-width' in
281 that it accounts for (i) continuation glyphs, (ii) the size of the
282 font, and (iii) the specified window.
284 ** New possible value for `system-type': nacl.
287 ** New variable `inhibit-message', when bound to non-nil, inhibits
288 `message' and related functions from displaying messages the Echo
289 Area. The output is still logged to the *Messages* buffer.
292 ** It is now safe for a mode that derives `tabulated-list-mode' to not
293 call `tabulated-list-init-header', in which case it will have no
297 ** `tabulated-list-print' takes a second optional argument, update,
298 which specifies an alternative printing method which is faster when
299 few or no entries have changed.
302 * Editing Changes in Emacs 25.1
304 ** Successive single-char deletions are collapsed in the undo-log just like
305 successive char insertions.
307 ** Unicode names entered via C-x 8 RET now use substring completion by default.
309 ** C-x 8 now has shorthands for these chars: ‐ ‑ ‒ – — ― ‘ ’ “ ” † ‡ • ′ ″
310 € № ← → ↔ − ≈ ≠ ≤ ≥. As before, you can type C-x 8 C-h to list shorthands.
312 ** New minor mode electric-quote-mode for quoting ‘like this’ and “like this”
313 as you type. See also the new variable ‘text-quoting-style’.
315 ** New minor mode global-eldoc-mode is enabled by default.
317 ** Emacs now supports "bracketed paste mode" when running on a terminal
318 that supports it. This facility allows Emacs to understand pasted
319 chunks of text as strings to be inserted, instead of interpreting each
320 character in the pasted text as actual user input. This results in a
321 paste experience similar to that under a window system, and significant
322 performance improvements when pasting large amounts of text.
324 ** Emacs now supports the latest version of the UBA.
325 The Emacs implementation of the Unicode Bidirectional Algorithm (UBA)
326 was updated to support all the latest additions and changes introduced
327 in Unicode Standard versions 6.3, 7.0, and the latest Unicode 8.0.
328 This includes full support for directional isolates and the
329 Bidirectional Parentheses Algorithm (BPA) specified by these Unicode
332 ** You can access `mouse-buffer-menu' (C-down-mouse-1) using C-f10.
335 ** New buffer-local `electric-pair-local-mode'.
338 * Changes in Specialized Modes and Packages in Emacs 25.1
340 ** New function `bookmark-set-no-overwrite' bound to C-x r M.
341 It raises an error if a bookmark of that name already exists,
342 unlike `bookmark-set' which silently updates an existing bookmark.
346 *** `json-pretty-print' and `json-pretty-print-buffer' now maintain
347 the ordering of object keys by default.
349 *** New commands `json-pretty-print-ordered' and
350 `json-pretty-print-buffer-ordered' pretty prints JSON objects with
351 object keys sorted alphabetically.
353 ** You can recompute the VC state of a file buffer with `M-x vc-refresh-state'
354 ** Prog mode has some support for multi-mode indentation.
355 See `prog-indentation-context' and `prog-widen'.
357 ** Prettify Symbols mode
358 *** Prettify Symbols mode supports custom composition predicates. By
359 overriding the default `prettify-symbols-compose-predicate', modes can
360 specify in which contexts a symbol map be composed to some unicode
361 character. `prettify-symbols-default-compose-p' is the default which
362 is suitable for most programming languages such as C or Lisp (but not
365 *** Symbols can be unprettified while point is inside them.
366 New variable `prettify-symbols-unprettify-at-point' configures this.
368 ** New `xterm-screen-extra-capabilities' config.
370 ** The `save-place' variable is replaced by a `save-place-mode'.
374 *** Hide message types by network or channel. `erc-hide-list' will
375 hide all messages of the specified type, where `erc-network-hide-list'
376 and `erc-channel-hide-list' will only hide the specified message types
377 for the respective specified targets.
380 *** `midnight-mode' is a proper minor mode.
381 *** clean-buffer-*-regexps can now specify buffers via predicate functions.
383 ** In xterms, killing text now also sets the CLIPBOARD/PRIMARY selection
384 in the surrounding GUI (using the OSC-52 escape sequence). This only works
385 if your xterm supports it and enables the `allowWindowOps' options (disabled
386 by default at least in Debian, for security reasons).
388 Similarly, you can yank the CLIPBOARD/PRIMARY selection (using the OSC-52
389 escape sequence) if your xterm has the feature enabled but for that you
390 additionally need to add `getSelection' to `xterm-extra-capabilities'.
392 ** xterm-mouse-mode now supports mouse-tracking (if your xterm supports it).
396 *** New "external" package status.
397 An external package is any installed package that's not built-in and
398 not from `package-user-dir', which usually means it's from an entry in
399 `package-directory-list'. They are treated much like built-in
400 packages, in that they cannot be deleted through the package menu and
401 are not considered for upgrades.
403 The effect, is that a user can manually place a specific version of a
404 package inside `package-directory-list' and the package menu will
407 *** If a package is available on multiple archives and one has higher
408 priority (as per `package-archive-priorities') only that one is
409 listed. This can be configured with `package-menu-hide-low-priority'.
411 *** `package-menu-toggle-hiding' now toggles the hiding of packages.
412 This includes the above-mentioned low-priority packages, as well as
413 available packages whose version is lower than the currently installed
414 version (which were previously impossible to display).
415 This allows users to downgrade a package if a lower version is
418 *** When filtering the package menu, keywords starting with "arc:" or
419 "status:" represent package archive or status, respectively, instead
422 *** Most functions which involve downloading information now take an
423 ASYNC argument. If it is non-nil, package.el performs the download(s)
426 *** New variable `package-menu-async' controls whether the
427 package-menu uses asynchronous downloads.
429 *** `package-install-from-buffer' and `package-install-file' work on directories.
430 This follows the same rules as installing from a .tar file, except the
431 -pkg file is optional.
433 *** Packages which are dependencies of other packages cannot be deleted.
434 The FORCE argument to `package-delete' overrides this.
436 *** New custom variable `package-selected-packages' tracks packages
437 which were installed by the user (as opposed to installed as
438 dependencies). This variable can also be manually customized.
440 *** New command `package-install-user-selected-packages' installs all
441 packages from `package-selected-packages' which are currently missing.
443 *** New command `package-autoremove' removes all packages which were
444 installed strictly as dependencies but are no longer needed.
448 When you invoke `shell' interactively, the *shell* buffer will now
449 display in a new window. However, you can customize this behavior via
450 the `display-buffer-alist' variable. For example, to get
451 the old behavior -- *shell* buffer displays in current window -- use
452 (add-to-list 'display-buffer-alist
453 '("^\\*shell\\*$" . (display-buffer-same-window))).
457 *** The `:protection' slot option is not obeyed any more.
459 *** The `newname' argument to constructors is optional&deprecated.
460 If you need your objects to be named, do it by inheriting from `eieio-named'.
462 *** The <class>-list-p and <class>-child-p functions are declared obsolete.
464 *** The <class> variables are declared obsolete.
466 *** The <initarg> variables are declared obsolete.
467 *** defgeneric and defmethod are declared obsolete.
469 *** `constructor' is now an obsolete alias for `make-instance'.
472 *** New command `ido-bury-buffer-at-head' bound to C-S-b
473 Bury the buffer at the head of `ido-matches', analogous to how C-k
474 kills the buffer at head.
475 *** A prefix argument to `ido-restrict-to-matches' will reverse its
476 meaning, and the list is restricted to those elements that do not
477 match the current input.
481 *** You can use <up> and <down> keys to move point in the multi-line
482 minibuffer just as in an ordinary buffer. Only when point moves over
483 the bottom/top of the minibuffer it goes to the next/previous history
484 element. The new commands bound to <up> and <down> in the minibuffer:
485 `next-line-or-history-element' and `previous-line-or-history-element'.
487 ** Search and Replace
489 *** Query-replace history is enhanced.
490 When query-replace reads the FROM string from the minibuffer, typing
491 `M-p' will now show previous replacements as "FROM SEP TO", where FROM
492 and TO are the original text and its replacement, and SEP is an arrow
493 string defined by the new variable `query-replace-from-to-separator'.
494 To select a prior replacement, type `M-p' until the desired
495 replacement appears in the minibuffer, and then exit the minibuffer by
500 *** If `quick-calc' is called with a prefix argument, insert the
501 result of the calculation into the current buffer.
504 ** In Edebug, you can now set the initial mode with C-x C-a C-m. With
505 this you can tell Edebug not to stop at the start of the first
506 instrumented function.
509 *** New minor mode `global-eldoc-mode'
510 *** `eldoc-documentation-function' now defaults to `ignore'
511 *** `describe-char-eldoc' displays information about character at point,
512 and can be used as a default value of `eldoc-documentation-function'. It is
513 useful when, for example, one needs to distinguish various spaces (e.g. ] [,
514 ] [, ] [, etc.) while using mono-spaced font.
519 *** HTML can now be rendered using variable-width fonts.
522 *** A new command `F' (`eww-toggle-fonts') can be used to toggle
523 whether to use variable-pitch fonts or not. The user can also
524 customize the `shr-use-fonts' variable.
527 *** A new command `C' (`eww-toggle-colors) can be used to toggle
528 whether to use the HTML-specified colors or not. The user can also
529 customize the `shr-use-colors variable.
532 *** A new command `R' (`eww-readable') will try do identify the main
533 textual parts of a web page and display only that, leaving menus and
534 the like off the page.
537 *** You can now use several eww buffers in parallel by renaming eww
538 buffers you want to keep separate.
541 *** Partial state of the eww buffers (the URIs and the titles of the
542 pages visited) is now preserved in the desktop file.
545 *** `eww-after-render-hook' is now called after eww has rendered
546 the data in the buffer.
549 *** The `eww-reload' command now takes a prefix to not reload via
550 the net, but just use the local copy of the HTML.
553 *** The DOM shr and eww uses has been changed to the general Emacs
554 xml.el/libxml2 DOM, and a new package dom.el has been added to
555 interact with this DOM. See the Emacs Lisp manual for interface
559 *** `mailcap-mime-data' is now consulted when displaying PDF files.
562 *** The new `S' command will list all eww buffers, and allow managing
566 *** https pages with valid certificates have headers marked in green, while
567 invalid certificates are marked in red.
571 *** text/html messages that contain inline image parts will be
572 transformed into multipart/related messages before sending.
575 *** New UPatterns `quote', `app', `cl-struct', and `eieio'.
576 *** New UPatterns can be defined with `pcase-defmacro'.
578 *** New vector QPattern.
581 *** Strings after `:documentation' are highlighted as docstrings.
584 *** Rectangle Mark mode can have corners past EOL or in the middle of a TAB.
585 *** C-x C-x in rectangle-mark-mode now cycles through the four corners.
586 *** `string-rectangle' provides on-the-fly preview of the result.
588 ** New font-lock functions font-lock-ensure and font-lock-flush, which
589 should be used instead of font-lock-fontify-buffer when called from Elisp.
591 ** Macro `minibuffer-with-setup-hook' takes (:append FUN) to mean
592 appending FUN to `minibuffer-setup-hook'.
595 *** New functions cl-fresh-line, cl-digit-char-p and cl-parse-integer.
597 ** Calendar and diary
600 *** The default `diary-file' is now located in .emacs.d.
603 *** New commands to insert diary entries with Chinese dates:
604 `diary-chinese-insert-anniversary-entry' `diary-chinese-insert-entry'
605 `diary-chinese-insert-monthly-entry', `diary-chinese-insert-yearly-entry'.
608 *** The calendar can now list and mark diary entries with Chinese dates.
609 See `diary-chinese-list-entries' and `diary-chinese-mark-entries'.
612 *** The option `calendar-mode-line-format' can now be nil,
613 which means to do nothing special with the mode line in calendars.
616 *** New option `calendar-weekend-days'.
617 The option customizes which day headers receive the
618 `calendar-weekend-header' face.
621 *** New optional args N and STRING for ‘holiday-greek-orthodox-easter’.
624 *** Many items obsolete since at least version 23.1 have been removed.
625 The majority were function/variable/face aliases, too numerous to list here.
628 **** Functions `calendar-one-frame-setup', `calendar-only-one-frame-setup',
629 `calendar-two-frame-setup', `european-calendar', `american-calendar'.
631 **** Hooks `cal-menu-load-hook', `cal-x-load-hook'.
633 **** Macro `calendar-for-loop'.
635 **** Variables `european-calendar-style', `diary-face', `hebrew-holidays-{1,4}'.
637 **** The nil and list forms of `diary-display-function'.
639 ** New ERT function `ert-summarize-tests-batch-and-exit'.
641 ** New js.el option `js-indent-first-init'.
644 ** `Info-fontify-maximum-menu-size' can be t for no limit.
647 ** `info-display-manual' can now be given a prefix argument which (any
648 non-nil value) directs the command to limit the completion
649 alternatives to currently visited manuals.
652 ** ntlm.el has support for NTLM2.
656 *** The Rmail commands d, C-d and u take optional repeat counts to delete or
657 undelete multiple messages.
659 *** Rmail can now render HTML mail messages if your Emacs was built with
660 libxml2 or if you have the Lynx browser installed. By default, Rmail
661 will display the HTML version of a mail message that has both HTML and
662 plain text parts, if display of HTML email is possible; customize the
663 `rmail-mime-prefer-html' option to `nil' if you don't want that.
666 *** In the commands that make summaries by subject, recipients, or senders,
667 you can no longer use commas to separate regular expressions.
669 ** SES now supports local printer functions; see `ses-define-local-printer'.
672 *** In sh-mode you can now use `sh-shell' as a file-local variable to
673 specify the type of shell in use (bash, csh, etc).
675 *** New value `always' for sh-indent-after-continuation.
676 This provides old-style ("dumb") indentation of continued lines.
680 *** Fatal TLS errors are now silent by default.
684 *** The URL package accepts now the protocols "ssh", "scp" and "rsync".
685 When `url-handler-mode' is enabled, file operations for these
686 protocols as well as for "telnet" and "ftp" are passed to Tramp.
688 *** The URL package allows customizing the `url-user-agent' string.
689 The new `url-user-agent' variable can be customized to be a string or
692 *** The new interface variable `url-request-noninteractive' can be used
693 to specify that we're running in a noninteractive context, and that
694 we should not be queried about things like TLS certificate validity.
696 *** If URL is used with a https connection, the first callback argument
697 plist will contain a :peer element that has the output of
698 `gnutls-peer-status' (if Emacs is built with GnuTLS support).
703 *** New connection method "afp", which allows to access Mac OS X
704 volumes via the Apple Filing Protocol.
707 *** New connection method "nc", which allows to access dumb busyboxes.
710 *** Method-specific parameters can be overwritten now with variable
711 `tramp-connection-properties'.
714 *** Handler for `file-notify-valid-p' for remote machines that support
715 filesystem notifications.
719 *** New user variable `sql-default-directory' enables remote
720 connections using Tramp.
722 *** New command `sql-send-line-and-next' sends the current line to the
723 interactive buffer and advances to the next line, skipping whitespace
726 *** Add support for Vertica SQL.
728 ** VC and related modes
730 *** Basic push support, via `vc-push', bound to `C-x v P'.
731 Implemented for Bzr, Git, Hg. As part of this change, the pre-existing
732 (undocumented) command vc-hg-push now behaves slightly differently.
734 *** The new command vc-region-history shows the log+diff of the active region.
736 *** New option `vc-annotate-background-mode' controls whether
737 the color range from `vc-annotate-color-map' is applied to the
738 background or to the foreground.
740 *** `compare-windows' now compares text with the most recently used window
741 instead of the next window. The new option `compare-windows-get-window-function'
742 allows to customize this.
744 *** Two new faces `compare-windows-removed' and `compare-windows-added'
745 replace the obsolete face `compare-windows'.
748 *** `log-edit-insert-changelog' converts "(tiny change)" to
749 "Copyright-paperwork-exempt: yes". Set `log-edit-rewrite-tiny-change'
752 ** VHDL mode supports VHDL'08.
754 ** Calculator: decimal display mode uses "," groups, so it's more
755 fitting for use in money calculations; factorial works with
758 ** HideIfDef mode now support full C/C++ expressions, argumented macro expansions,
759 interactive macro evaluation and automatic scanning of #defined symbols.
761 *** New custom variable `hide-ifdef-header-regexp' to define C/C++ header file
762 name patterns. Default case-insensitive .h, .hh, .hpp, .hxx, and .h++.
763 *** New custom variable `hide-ifdef-expand-reinclusion-protection' to prevent
764 reinclusion protected header files from being fully hidden.
765 *** New custom variable `hide-ifdef-exclude-define-regexp' to define symbol
766 name patterns (e.g. all "FOR_DOXYGEN_ONLY_*") to be excluded.
770 *** New custom variable `tex-print-file-extension' to help users who
771 use PDF instead of DVI.
773 *** TeX mode now supports Prettify Symbols mode. When enabling
774 `prettify-symbols-mode' in a tex-mode buffer, \alpha ... \omega, and
775 many other math macros are displayed using unicode characters.
777 ** whitespace-mode: new 'big-indent style highlighting too much indentation.
778 By default, 32 spaces and four TABs are considered to be too much but
779 `whitespace-big-indent-regexp' can be configured to change that.
781 ** tildify: `tildify-space-string', `tildify-pattern', and
782 `tildify-foreach-region-function' variables added making
783 `tildify-string-alist', `tildify-pattern-alist', and
784 `tildify-ignored-environments-alist' variables (as well as a few
785 helper functions) obsolete.
788 The new package provides generic framework and new commands to find
789 and move to definitions, as well as pop back to the original location.
792 `xref-find-definitions' replaces `find-tag' and provides an interface
793 to pick one destination among several. Hence, `tags-loop-continue' is
794 unbound. `xref-pop-marker-stack' replaces `pop-tag-mark', but uses an
795 easier binding, which is now unoccupied (`M-,').
796 `xref-find-definitions-other-window' replaces `find-tag-other-window'.
797 `xref-find-definitions-other-frame' replaces `find-tag-other-frame'.
798 `xref-find-apropos' replaces `find-tag-regexp'.
801 `find-tag-marker-ring-length' is now an obsolete alias for
802 `xref-marker-ring-length'. `find-tag-marker-ring' is now an obsolete
803 alias for a private variable. `xref-push-marker-stack' and
804 `xref-pop-marker-stack' should be used to mutate it instead.
807 As a result of the above, these commands are now obsolete:
808 `find-tag-other-window', `find-tag-other-frame', `find-tag-regexp',
809 `tags-apropos' and `tags-loop-continue'.
812 EUDC's LDAP backend has been improved.
814 *** EUDC supports LDAP-over-SSL URLs (ldaps://).
816 *** EUDC passes LDAP passwords through a pipe to the ldapsearch
817 subprocess instead of on the command line.
819 *** EUDC handles LDAP wildcards automatically so the user shouldn't
820 need to configure this manually anymore.
822 *** The LDAP configuration section of EUDC's manual has been
825 There have also been customization changes.
827 *** New custom variable `eudc-server-hotlist' to allow specifying
828 multiple EUDC servers in init file.
830 *** Custom variable `eudc-inline-query-format' defaults to completing
831 on email and firstname instead of surname.
833 *** Custom variable `eudc-expansion-overwrites-query' defaults to nil
834 to avoid interfering with the kill ring.
836 *** Custom variable `eudc-inline-expansion-format' defaults to
837 "Firstname Surname <mail-address>".
839 *** Custom variable `eudc-options-file' defaults to
840 "~/.emacs.d/eudc-options".
842 *** New custom variable `ldap-ldapsearch-password-prompt-regexp' to
843 allow overriding the regular expression that recognizes the ldapsearch
844 command line's password prompt.
849 *** The new built-in command `clear' can scroll window contents out of sight.
850 If provided with an optional non-nil argument, the scrollback contents will be cleared.
852 *** New buffer syntax '#<buffer-name>', which is equivalent to
853 '#<buffer buffer-name>'. This shorthand makes interacting with
854 buffers from eshell more convenient. Custom variable
855 `eshell-buffer-shorthand', which has been broken for a while, has been
858 *** By default, eshell "visual" program buffers (created by
859 `eshell-visual-commands' and similar custom vars) are no longer killed
860 when their processes die. This fixes issues with short-lived commands
861 and makes visual programs more useful in general. For example, if
862 "git log" is a visual command, it will always show the visual command
863 buffer, even if the "git log" process dies. For the old behavior,
864 make the new option `eshell-destroy-buffer-when-process-dies' non-nil.
868 *** Support for the Conkeror web browser.
871 *** Support for several ancient browsers is now officially obsolete.
874 ** tar-mode: new `tar-new-entry' command, allowing for new members to
875 be added to the archive.
878 ** Autorevert: dired buffers are also auto-reverted via file
879 notifications, if Emacs is compiled with file notification support.
881 ** File Notifications
884 *** The new event `stopped' signals, that a file notification watch is
885 not active any longer.
888 *** The new function `file-notify-valid-p' checks, whether a file
889 notification descriptor still corresponds to an activate watch.
894 *** The command `dired-do-compress' bound to `Z' now can compress
895 directories and decompress zip files.
898 *** New command `dired-do-compress-to' bound to `c' can be used to
899 compress many marked files into a single named archive. The
900 compression command is determined from the new
901 `dired-compress-files-alist' variable.
908 *** landmark.el (moved to elpa.gnu.org)
911 * New Modes and Packages in Emacs 25.1
913 ** pinentry.el allows GnuPG passphrase to be prompted through the
914 minibuffer instead of a graphical dialog, depending on whether the gpg
915 command is called from Emacs (i.e., INSIDE_EMACS environment variable
916 is set). This feature requires newer versions of GnuPG (2.1.5 or
917 later) and Pinentry (0.9.5 or later).
919 ** cl-generic.el provides CLOS-style multiple-dispatch generic functions.
921 ** scss-mode (a minor variant of css-mode)
923 ** let-alist is a new macro (and a package) that allows one to easily
924 let-bind the values stored in an alist.
926 ** `tildify-mode' allows to automatically insert hard spaces as one
927 types the text. Breaking line after a single-character words is
928 forbidden by Czech and Polish typography (and may be discouraged in
929 other languages), so `auto-tildify-mode' makes it easier to create
930 a typographically-correct documents.
932 ** The `seq' library adds sequence manipulation functions and macros
933 that complement basic functions provided by subr.el. All functions
934 are prefixed with `seq-' and work on lists, strings and vectors.
936 ** The `map' library provides map-manipulation functions that work on
937 alists, hash-table and arrays. All functions are prefixed with
940 ** The `thunk' library provides functions and macros to control the
943 ** js-jsx-mode (a minor variant of js-mode) provides indentation
944 support for JSX, an XML-like syntax extension to ECMAScript.
947 * Incompatible Lisp Changes in Emacs 25.1
949 ** `syntax-begin-function' is declared obsolete.
950 Removed font-lock-beginning-of-syntax-function and the SYNTAX-BEGIN
951 slot in font-lock-defaults.
954 ** `package-initialize' now sets `package-enable-at-startup' to nil if
955 called during startup. Users who call this function in their init
956 file and still expect it to be run after startup should set
957 `package-enable-at-startup' to t after the call to
958 `package-initialize'.
960 ** `:global' minor mode use `setq-default' rather than `setq'.
961 This means that you can't use `make-local-variable' and expect them to
962 "magically" become buffer-local.
964 ** `inhibit-point-motion-hooks' now defaults to t and is obsolete.
967 ** `track-mouse' no longer freezes the shape of the mouse pointer.
968 The `track-mouse' form no longer refrains from changing the shape of
969 the mouse pointer for the entire time the body of that form is
970 executed. Lisp programs that use `track-mouse' for dragging across
971 large portions of the Emacs display, and want to avoid changes in the
972 pointer shape during dragging, should bind the variable `track-mouse'
973 to the special value `dragging' in the body of the form.
975 ** The optional `predicate' argument of `lisp-complete-symbol' no longer
976 has any effect. (This change was made in Emacs 24.4 but was not
977 advertised at the time.)
979 ** `indirect-function' does not signal `void-function' any more.
980 This is mostly a bug-fix, since this change was missed back in 24.4 when
981 symbol-function was changed not to signal `void-function' any more.
982 *** As a consequence, the second arg of `indirect-function' is now obsolete.
984 ** Comint, term, and compile do not set the EMACS env var any more.
985 Use the INSIDE_EMACS environment variable instead.
987 ** `save-excursion' does not save&restore the mark any more.
989 ** read-buffer-function can now be called with a 4th argument (`predicate').
991 ** completion-table-dynamic stays in the minibuffer.
992 If you want the old behavior of calling the function in the buffer
993 from which the minibuffer was entered, call it with the new argument
996 ** window-configurations no longer record the buffers' marks.
998 ** inhibit-modification-hooks now also inhibits lock-file checks, as well as
999 active region handling.
1001 ** deactivate-mark is now buffer-local.
1003 ** `cl-the' now asserts that its argument is of the given type.
1005 ** `process-running-child-p` may now return a numeric process
1006 group ID instead of `t'.
1009 ** Mouse click events on mode line or header line no longer include
1010 any reference to a buffer position. The 6th member of the mouse
1011 position list returned for such events is now nil.
1013 ** Menu items in keymaps do not support the "key shortcut cache" any more.
1014 These slots used to hold key-shortcut data, but have been obsolete since
1017 ** Emacs no longer downcases the first letter of a system diagnostic
1018 when signaling a file error. For example, it now reports "Permission
1019 denied" instead of "permission denied". The old behavior was problematic
1020 in languages like German where downcasing rules depend on grammar.
1023 ** New variable ‘text-quoting-style’ to control how Emacs translates quotes.
1024 Set it to ‘curve’ for curved single quotes ‘like this’, to ‘straight’
1025 for straight apostrophes 'like this', and to ‘grave’ for grave accent
1026 and apostrophe `like this'. The default value nil acts like ‘curve’
1027 if curved single quotes are displayable, and like ‘grave’ otherwise.
1028 The new variable affects display of diagnostics and help, but not of info.
1031 ** substitute-command-keys now replaces quotes.
1032 That is, it converts documentation strings’ quoting style as per the
1033 value of ‘text-quoting-style’. Doc strings in source code can use
1034 either curved single quotes or grave accents and apostrophes. As
1035 before, characters preceded by \= are output as-is.
1038 ** Message-issuing functions ‘error’, ‘message’, etc. now convert quotes.
1039 They use the new ‘format-message’ function instead of plain ‘format’,
1040 so that they now follow user preference as per ‘text-quoting-style’
1041 when processing curved single quotes, grave accents, and apostrophes
1042 in their format argument.
1045 ** The character classes [:alpha:] and [:alnum:] in regular expressions
1046 now match multibyte characters using Unicode character properties.
1047 If you want the old behavior where they matched any character with
1048 word syntax, use `\sw' instead.
1051 ** The character classes [:graph:] and [:print:] in regular expressions
1052 no longer match every multibyte character. Instead, Emacs now
1053 consults the Unicode character properties to determine which
1054 characters are graphic or printable. In particular, surrogates and
1055 unassigned codepoints are now rejected. If you want the old behavior,
1056 use [:multibyte:] instead.
1059 ** The `diff' command uses the unified format now. To restore the old
1060 behavior, set `diff-switches' to `-c'.
1062 ** `grep-template' and `grep-find-template' values don't include the
1063 --color argument anymore. It's added at the <C> place holder position
1064 dynamically. Any third-party code that changes these templates should
1065 be updated accordingly.
1068 ** ‘(/ N)’ is now equivalent to ‘(/ 1 N)’ rather than to ‘(/ N 1)’.
1069 The new behavior is compatible with Common Lisp and with XEmacs.
1070 This change does not affect Lisp code intended to be portable to
1071 Emacs 24.2 and earlier, which did not support unary ‘/’.
1074 ** The `default-directory' value doesn't have to end slash. To make
1075 that happen, `unhandled-file-name-directory' now defaults to calling
1076 `file-name-as-directory'.
1079 * Lisp Changes in Emacs 25.1
1081 ** syntax-propertize is now automatically called on-demand during forward
1082 parsing functions like `forward-sexp'.
1084 ** New hooks prefix-command-echo-keystrokes-functions and
1085 prefix-command-preserve-state-hook, to allow the definition of prefix
1086 commands other than the predefined C-u.
1088 ** New functions `filepos-to-bufferpos' and `bufferpos-to-filepos'.
1090 ** The default value of `load-read-function' is now `read'.
1092 ** New hook `pre-redisplay-functions', a bit easier to use than pre-redisplay-function.
1094 ** The second arg of `looking-back' should always be provided explicitly.
1096 ** Obsolete text properties `intangible', `point-entered', and `point-left'.
1097 Replaced by properties `cursor-intangible' and `cursor-sensor-functions',
1098 implemented by the new `cursor-intangible-mode' and
1099 `cursor-sensor-mode' minor modes.
1101 ** New process type `pipe', which can be used in combination with the
1102 `:stderr' keyword of make-process to handle standard error output
1105 ** New function `make-process' provides an alternative interface to
1106 `start-process'. It allows programs to set process parameters such as
1107 process filter, sentinel, etc., through keyword arguments (similar to
1108 `make-network-process').
1110 ** `read-buffer' takes a new `predicate' argument.
1112 ** Emacs Lisp now supports generators.
1114 ** New finalizer facility for running code when objects
1117 ** lexical closures can use (:documentation <form>) to build their docstring.
1118 It should be placed right where the docstring would be, and <form> is then
1119 evaluated (and should return a string) when the closure is built.
1121 ** define-inline provides a new way to define inlinable functions.
1123 ** New function `macroexpand-1' to perform a single step of macroexpansion.
1125 ** Some "x-*" were obsoleted:
1126 *** x-select-text is renamed gui-select-text.
1127 *** x-selection-value is renamed gui-selection-value.
1128 *** x-get-selection is renamed gui-get-selection.
1129 *** x-get-clipboard and x-clipboard-yank are marked obsolete.
1130 *** x-get-selection-value is renamed to gui-get-primary-selection.
1131 *** x-set-selection is renamed to gui-set-selection
1133 ** New function `string-greaterp', which return the opposite result of
1136 ** New function `alist-get', which is also a valid place (aka lvalue).
1138 ** New function `funcall-interactively', which works like `funcall'
1139 but makes `called-interactively-p' treat the function as (you guessed it)
1140 called interactively.
1142 ** New function `function-put' to use instead of `put' for function properties.
1145 ** New properties that can be specified with `declare':
1146 *** (interactive-only INSTEAD), says to use INSTEAD for non-interactive use.
1147 *** (pure VAL), if VAL is non-nil, indicates the function is pure.
1148 *** (side-effect-free VAL), if VAL is non-nil, indicates the function does not
1152 ** New macro `with-file-modes', for evaluating expressions with default file
1153 permissions set to temporary values (e.g., for creating private files).
1155 ** You can access the slots of structures using `cl-struct-slot-value'.
1157 ** Function `sort' can deal with vectors.
1159 ** Function `system-name' now returns an updated value if the current
1160 system's name has changed or if the Emacs process has changed systems,
1161 and to avoid long waits it no longer consults DNS to canonicalize the
1162 name. The variable `system-name' is now obsolete.
1165 ** Function `write-region' no longer outputs "Wrote FILE" in batch mode.
1167 ** If `pwd' is called with a prefix argument, insert the current default
1171 ** New utilities in subr-x.el:
1172 *** New macros `if-let' and `when-let' allow defining bindings and to
1173 execute code depending whether all values are true.
1174 *** New macros `thread-first' and `thread-last' allow threading a form
1175 as the first or last argument of subsequent forms.
1178 ** Documentation strings now support quoting with curved single quotes
1179 ‘like-this’ in addition to the old style with grave accent and
1180 apostrophe `like-this'. The new style looks better on today's displays.
1181 In the new Electric Quote mode, you can enter curved single quotes
1182 into documentation by typing ` and '. Outside Electric Quote mode,
1183 you can enter them by typing ‘C-x 8 [’ and ‘C-x 8 ]’, or (if your Alt
1184 key works) by typing ‘A-[’ and ‘A-]’. As described above under
1185 ‘text-quoting-style’, the user can specify how to display doc string
1189 ** New function ‘format-message’ is like ‘format’ and also converts
1190 curved single quotes, grave accents and apostrophes as per
1191 ‘text-quoting-style’.
1194 ** show-help-function's arg is converted via substitute-command-keys
1195 before being passed to the function. Help strings, help-echo
1196 properties, etc. can therefore contain command key escapes and
1200 ** Time-related changes:
1202 *** Time conversion functions now accept an optional ZONE argument
1203 that specifies the time zone rules for conversion. ZONE is omitted or
1204 nil for Emacs local time, t for Universal Time, ‘wall’ for system wall
1205 clock time, or a string as in ‘set-time-zone-rule’ for a time zone
1206 rule. The affected functions are ‘current-time-string’,
1207 ‘current-time-zone’, ‘decode-time’, and ‘format-time-string’. The
1208 function ‘encode-time’, which already accepted a simple time zone rule
1209 argument, has been extended to accept all the new forms.
1211 *** Time-related functions now consistently accept numbers
1212 (representing seconds since the epoch) and nil (representing the
1213 current time) as well as the usual list-of-integer representation.
1214 Affected functions include `current-time-string', `current-time-zone',
1215 `decode-time', `float-time', `format-time-string', `seconds-to-time',
1216 `time-add', `time-less-p', `time-subtract', `time-to-day-in-year',
1217 `time-to-days', and `time-to-seconds'.
1219 *** The `encode-time-value' and `with-decoded-time-value' macros have
1222 *** `calendar-next-time-zone-transition', `time-add', and
1223 `time-subtract' no longer return time values in the obsolete and
1224 undocumented integer-pair format. Instead, they return a list of two
1228 ** New function `set-binary-mode' allows to switch a standard stream
1229 of the Emacs process to binary I/O mode.
1231 ** ASCII approximations to curved quotes are put in standard-display-table
1232 if the terminal cannot display curved quotes.
1234 ** Standard output and error streams now transliterate characters via
1235 standard-display-table, and encode output using locale-coding-system.
1237 ** Miscellaneous name change
1239 For consistency with the usual Emacs spelling, the Lisp variable
1240 `hfy-optimisations' has been renamed to `hfy-optimizations'.
1241 The old name should still work, as an obsolescent alias.
1244 * Changes in Frames and Windows Code in Emacs 25.1
1247 ** Emacs can now draw horizontal scroll bars on some platforms that
1248 provide toolkit scroll bars, namely Gtk+, Lucid, Motif and Windows.
1249 Horizontal scroll bars are turned off by default.
1250 *** New function `horizontal-scroll-bars-available-p' telling whether
1251 horizontal scroll bars are available on the underlying system.
1252 *** New mode `horizontal-scroll-bar-mode' to toggle horizontal scroll
1253 bars on all existing and future frames.
1254 *** New function `toggle-horizontal-scroll-bar' to toggle horizontal
1255 scroll bars on the selected frame.
1256 *** New frame parameters `horizontal-scroll-bars' and
1257 `scroll-bar-height' to set horizontal scroll bars and their height
1258 for individual frames and in `default-frame-alist'.
1259 *** New functions `frame-scroll-bar-height' and
1260 `window-scroll-bar-height' return the height of horizontal scroll
1261 bars on a specific frame or window.
1262 *** `set-window-scroll-bars' now accepts five parameters where the last
1263 two specify height and type of the window's horizontal scroll bar.
1264 *** `window-scroll-bars' now returns type and sizes of horizontal scroll
1266 *** New buffer-local variables `horizontal-scroll-bar' and
1267 `scroll-bar-height'.
1270 ** New functions `frame-geometry' and `frame-edges' give access to a
1274 ** New functions `mouse-absolute-pixel-position' and
1275 `set-mouse-absolute-pixel-position' get/set screen coordinates of the
1279 ** The function `window-edges' now accepts three additional arguments to
1280 retrieve body, absolute and pixel edges of the window.
1283 ** The functions `window-inside-edges', `window-inside-pixel-edges' and
1284 `window-inside-absolute-pixel-edges' have been renamed to respectively
1285 `window-body-edges', `window-body-pixel-edges' and
1286 `window-absolute-body-pixel-edges'. The old names are kept as aliases.
1289 ** New function `window-absolute-pixel-position' to get the screen
1290 coordinates of a visible buffer position.
1293 ** The height of a frame's menu and tool bar are no longer counted in the
1294 frame's text height. This means that the text height stands only for
1295 the height of the frame's root window plus that of the echo area (if
1296 present). This was already the behavior for frames with external tool
1297 and menu bars (like in the Gtk builds) but has now been extended to all
1301 ** Frames now do not necessarily preserve the number of columns or lines
1302 they display when setting default font, menu bar, fringe width, or
1303 scroll bars. In particular, maximized and fullscreen frames are
1304 conceptually never resized if such settings change. For fullheight and
1305 fullwidth frames, the behavior may depend on the toolkit used.
1306 *** New option `frame-inhibit-implied-resize' if non-nil, means that
1307 setting default font, menu bar, fringe width, or scroll bars of a
1308 specific frame does not resize that frame in order to preserve the
1309 number of columns or lines it displays.
1312 ** New function `window-preserve-size' allows to preserve the size of
1313 windows without "fixing" it. It's supported by `fit-window-to-buffer',
1314 `temp-buffer-resize-mode' and `display-buffer'.
1317 ** New minor mode `window-divider-mode' and options
1318 `window-divider-default-places', `window-divider-default-bottom-width'
1319 and `window-divider-default-right-width'.
1322 ** New option `switch-to-buffer-in-dedicated-window' allows to customize
1323 how `switch-to-buffer' proceeds interactively when the selected window
1324 is strongly dedicated to its buffer.
1327 ** The option `even-window-heights' has been renamed to
1328 `even-window-sizes' and now handles window widths as well.
1330 ** Tearoff menus and detachable toolbars for Gtk+ has been removed.
1331 Those features have been deprecated in Gtk+ for a long time.
1335 *** etags no longer qualifies class members by default.
1336 By default, `etags' will not qualify class members for C-like
1337 object-oriented languages with their class names and namespaces, and
1338 will remove qualifications used explicitly in the code from the tag
1339 names it puts in TAGS files. This is so the etags.el back-end for
1340 `xref-find-definitions' is more accurate and produces less false
1343 Use --class-qualify (-Q) if you want the old default behavior of
1344 qualifying class members in C++, Java, and Objective C. Note that
1345 using -Q might make some class members become "unknown" to `M-.'
1346 (`xref-find-definitions'); if so, you can use `C-u M-.' to specify the
1347 qualified names by hand.
1350 * Changes in Emacs 25.1 on Non-Free Operating Systems
1353 ** MS-Windows specific Emacs build scripts are no longer in the distribution
1354 This includes the makefile.w32-in files in various subdirectories, and
1355 the support files. The file nt/configure.bat now just tells the user
1356 to use the procedure described in nt/INSTALL, by running the Posix
1357 `configure' script in the top-level directory.
1360 ** Building Emacs for MS-Windows requires at least Windows XP
1361 or Windows Server 2003. The built binaries still run on all versions
1362 of Windows starting with Windows 9X.
1365 ** Emacs running on MS-Windows now supports the daemon mode.
1367 ** The byte counts in etags-generated TAGS files are now the same on
1368 MS-Windows as they are on other platforms.
1371 ** On OS X, configure creates a Cocoa ("Nextstep") build by default.
1372 Pass '--without-ns' to configure to create an X11 build, the old default.
1374 ** OS X 10.5 or older is no longer supported.
1376 ** OS X on PowerPC is no longer supported.
1379 ** The new function 'w32-application-type' returns the type of an
1380 MS-Windows application given the name of its executable program file.
