* Installation Changes in Emacs 25.1

+++
** Building Emacs now requires C99 or later.

+++
** Building Emacs now requires GNU make, version 3.81 or later.

+++
** New configure option --with-cairo.
This builds Emacs with Cairo drawing.  As a side effect, it provides
support for built-in printing, when Emacs was built with GTK+.

** New configure option --with-modules.
This enables support for loading dynamic modules; see below.

---
** By default, Emacs no longer works on IRIX.  We expect that Emacs
users are not affected by this, as SGI stopped supporting IRIX in
December 2013.  If you are affected, please send a bug report.  You
should be able to work around the problem either by porting the Emacs
undumping code to GCC under IRIX, or by configuring --with-wide-int,
or by sticking with Emacs 24.4.

---
** The Emacs garbage collector assumes GC_MARK_STACK == GC_MAKE_GCPROS_NOOPS.
The GC_MAKE_GCPROS_NOOPS stack-marking variant has been the default
since Emacs 24.4, and the other variants were undocumented and were
obstacles to maintenance and development.  GC_MARK_STACK and its
related symbols have been removed from the C internals.

---
** 'configure' now prefers gnustep-config when configuring GNUstep.
If gnustep-config is not available, the old heuristics are used.

---
** 'configure' now prefers inotify to gfile for file notification,
unless gfile is explicitly requested via --with-file-notification='gfile'.

---
** The configure option '--with-pkg-config-prog' has been removed.
Use './configure PKG_CONFIG=/full/name/of/pkg-config' if you need to.

---
** The configure option '--with-mmdf' has been removed.
It was no longer useful, as it relied on libraries that are no longer
supported, and its presence led to confusion during configuration.
This affects only the 'movemail' utility; Emacs itself can still
process MMDF-format files as before.

+++
** The configure option '--enable-silent-rules' is now the default,
and silent rules are now quieter.  To get the old behavior where
'make' chatters a lot, configure with '--disable-silent-rules' or
build with 'make V=1'.

---
** The configure option '--with-gameuser' now allows to specify a
group instead of a user if its argument is prefixed by ':' (a colon).
This will cause the game score files in ${localstatedir}/games/emacs
to be owned by that group, and the helper program for updating them to
be installed setgid.  The option now defaults to the 'games' group.

---
** The `grep-changelog' script (and its manual page) are no longer included.
It has no particular connection to Emacs and has not changed in years,
so if you want to use it, you can always take a copy from an older Emacs.

---
** Emacs 25 comes with a new set of icons.
Various resolutions are available as etc/images/icons/hicolor/*/apps/emacs.png.
The old Emacs logo icons are available as `emacs23.png' in the same location.

\f
* Startup Changes in Emacs 25.1

+++
** When Emacs is given a file as a command line argument and
`initial-buffer-choice' is non-nil, display both the file and
`initial-buffer-choice'.  When Emacs is given more than one file and
`initial-buffer-choice' is non-nil, show `initial-buffer-choice'
and *Buffer List*.  This makes Emacs convenient to use from the
command line when `initial-buffer-choice' is non-nil.

+++
** The value of ‘initial-scratch-message’ is now treated as a doc string
and can contain escape sequences for command keys, quotes, and the like.

\f
* Changes in Emacs 25.1

+++
** Any file of the form .dir-locals*.el is now considered a dir-local
file, and multiple such files can be used in the same directory.  See
the variable `dir-locals-file' for more information.

---
** `xref-find-definitions' and `describe-function' now display
information about mode local overrides (defined by cedet/mode-local.el
`define-overloadable-function' `define-mode-local-overrides').

+++
** New `display-buffer' action function `display-buffer-use-some-frame'.
This displays the buffer in an existing frame other than the current
frame, and allows the caller to specify a frame predicate to exclude
frames.

+++
** New documentation command `describe-symbol'.
Works for functions, variables, faces, etc.  It is bound to `C-h o' by
default.

+++
** New function `custom-prompt-customize-unsaved-options' checks for
unsaved customizations and prompts user to customize (if found).  It
is intended for adding to 'kill-emacs-query-functions'.

+++
** Network security (TLS/SSL certificate validity and the like) is
added via the new Network Security Manager (NSM) and controlled via
the `network-security-level' variable.

+++
** C-h l now also lists the commands that were run.

+++
** x-select-enable-clipboard is renamed select-enable-clipboard
and x-select-enable-primary is renamed select-enable-primary.
Additionally they both now apply to all systems (OSX, GNUstep, Windows, you
name it), with the proviso that on some systems (e.g. Windows)
select-enable-primary is ineffective since the system doesn't
have the equivalent of a primary selection.

+++
** terpri gets an optional arg ENSURE to conditionally output a newline.

+++
** New macro `define-advice'.

+++
** `insert-register' now leaves point after the inserted text
when called interactively.  A prefix argument toggles this behavior.

+++
** The new variable `term-file-aliases' replaces some files from lisp/term.
The function `tty-run-terminal-initialization' consults this variable
when deciding what terminal-specific initialization code to run.

---
** New variable `system-configuration-features', listing some of the
main features that Emacs was compiled with.  This is mainly intended
for use in Emacs bug reports.

+++
** A password is now hidden also when typed in batch mode.  Another
hiding character but the default `.' can be used by let-binding the
variable `read-hide-char'.

** Emacs can now load shared/dynamic libraries (modules).
A dynamic Emacs module is a shared library that provides additional
functionality for use in Emacs Lisp programs, just like a package
written in Emacs Lisp would.  The functions `load', `require',
`load-file', etc. were extended to load such modules, as they do with
Emacs Lisp packages.  The new variable `module-file-suffix' holds the
system-dependent value of the file-name extension (`.so' on Posix
hosts) of the module files.

A module should export a C-callable function named
`emacs_module_init', which Emacs will call as part of the call to
`load' or `require' which loads the module.  It should also export a
symbol named `plugin_is_GPL_compatible' to indicate that its code is
released under the GPL or compatible license; Emacs will refuse to
load modules that don't export such a symbol.

If a module needs to call Emacs functions, it should do so through the
API defined and documented in the header file `emacs-module.h'.  Note
that any module that provides Lisp-callable functions will have to use
Emacs functions such as `fset' and `funcall', in order to register its
functions with the Emacs Lisp interpreter.

Modules can create `user-ptr' Lisp objects that embed pointers to C
struct's defined by the module.  This is useful for keeping around
complex data structures created by a module, to be passed back to the
module's functions.  User-ptr objects can also have associated
"finalizers" -- functions to be run when the object is GC'ed; this is
useful for freeing any resources allocated for the underlying data
structure, such as memory, open file descriptors, etc.  A new
predicate `user-ptrp' returns non-nil if its argument is a `user-ptr'
object.

Loadable modules in Emacs are an experimental feature, and subject to
change in future releases.  For that reason, their support is disabled
by default, and must be enabled by using the `--with-modules' option
at configure time.

---
** New input method: `tamil-dvorak'.

\f
* Editing Changes in Emacs 25.1

+++
** M-x suggests shorthands and ignores obsolete commands for completion.

** Changes in undo

+++
*** Successive single-char deletions are collapsed in the undo-log just like
successive char insertions.  Which commands invoke this behavior is
controlled by the new `undo-auto-amalgamate' function.  See the node
"Undo" in the ELisp manual for more details.

+++
*** The heuristic used to insert `undo-boundary' after each command
has changed, so that if a command causes changes in more than just the
current buffer, Emacs now calls `undo-boundary' in every buffer
affected by the command.

+++
** New command `comment-line' bound to `C-x C-;'.

** New and improved facilities for inserting Unicode characters

---
*** Unicode names entered via C-x 8 RET now use substring completion by default.

+++
*** C-x 8 now has shorthands for these chars: ‐ ‑ ‒ – — ― ‘ ’ “ ” † ‡ • ′ ″
€ № ← → ↔ − ≈ ≠ ≤ ≥.  As before, you can type C-x 8 C-h to list shorthands.

+++
*** New minor mode electric-quote-mode for quoting ‘like this’ and “like this”
as you type.  See also the new variable ‘text-quoting-style’.

---
** New minor mode global-eldoc-mode is enabled by default.

---
** Emacs now supports "bracketed paste mode" when running on a terminal
that supports it.  This facility allows Emacs to understand pasted
chunks of text as strings to be inserted, instead of interpreting each
character in the pasted text as actual user input.  This results in a
paste experience similar to that under a window system, and significant
performance improvements when pasting large amounts of text.

+++
** Emacs now supports the latest version of the UBA.
The Emacs implementation of the Unicode Bidirectional Algorithm (UBA)
was updated to support all the latest additions and changes introduced
in Unicode Standard versions 6.3, 7.0, and the latest Unicode 8.0.
This includes full support for directional isolates and the
Bidirectional Parentheses Algorithm (BPA) specified by these Unicode
standards.

+++
** You can access `mouse-buffer-menu' (C-down-mouse-1) using C-f10.

+++
** New buffer-local `electric-pair-local-mode'.

+++
** New variable `fast-but-imprecise-scrolling' inhibits
fontification during full screen scrolling operations, giving less
hesitant operation during auto-repeat of C-v, M-v at the cost of
possible inaccuracies in the end position.

\f
* Changes in Specialized Modes and Packages in Emacs 25.1

** Checkdoc

+++
*** New command `checkdoc-package-keywords' checks if the
current package keywords are recognized.  Set the new option
`checkdoc-package-keywords-flag' to non-nil to make
`checkdoc-current-buffer' call this function automatically.

+++
*** New function `checkdoc-file' checks for style errors.
It's meant for use together with `compile':
emacs -batch --eval "(checkdoc-file \"subr.el\")"

+++
** New function `bookmark-set-no-overwrite' bound to C-x r M.
It raises an error if a bookmark of that name already exists,
unlike `bookmark-set' which silently updates an existing bookmark.

** JSON

---
*** `json-pretty-print' and `json-pretty-print-buffer' now maintain
the ordering of object keys by default.

---
*** New commands `json-pretty-print-ordered' and
`json-pretty-print-buffer-ordered' pretty prints JSON objects with
object keys sorted alphabetically.

+++
** Prog mode has some support for multi-mode indentation.
This allows better indentation support in modes that support multiple
programming languages in the same buffer, like literate programming
environments or ANTLR programs with embedded Python code.

A major mode can provide indentation context for a sub-mode through
the `prog-indentation-context' variable.  To support this, modes that
provide indentation should use `prog-widen' instead of `widen' and
`prog-first-column' instead of a literal zero.  See the node
"Mode-Specific Indent" in the ELisp manual for more details.

** Prettify Symbols mode

*** Prettify Symbols mode supports custom composition predicates.  By
overriding the default `prettify-symbols-compose-predicate', modes can
specify in which contexts a symbol map be composed to some unicode
character.  `prettify-symbols-default-compose-p' is the default which
is suitable for most programming languages such as C or Lisp (but not
(La)TeX).

*** Symbols can be unprettified while point is inside them.
New variable `prettify-symbols-unprettify-at-point' configures this.

** New `xterm-screen-extra-capabilities' config.

** The `save-place' variable is replaced by a `save-place-mode'.

** ERC

*** Hide message types by network or channel.  `erc-hide-list' will
hide all messages of the specified type, where `erc-network-hide-list'
and `erc-channel-hide-list' will only hide the specified message types
for the respective specified targets.

** Midnight-mode

*** `midnight-mode' is a proper minor mode.

*** clean-buffer-*-regexps can now specify buffers via predicate functions.

** In xterms, killing text now also sets the CLIPBOARD/PRIMARY selection
in the surrounding GUI (using the OSC-52 escape sequence).  This only works
if your xterm supports it and enables the `allowWindowOps' options (disabled
by default at least in Debian, for security reasons).

Similarly, you can yank the CLIPBOARD/PRIMARY selection (using the OSC-52
escape sequence) if your xterm has the feature enabled but for that you
additionally need to add `getSelection' to `xterm-extra-capabilities'.

** xterm-mouse-mode now supports mouse-tracking (if your xterm supports it).

** package.el

*** New "external" package status.
An external package is any installed package that's not built-in and
not from `package-user-dir', which usually means it's from an entry in
`package-directory-list'.  They are treated much like built-in
packages, in that they cannot be deleted through the package menu and
are not considered for upgrades.

The effect, is that a user can manually place a specific version of a
package inside `package-directory-list' and the package menu will
always respect that.

*** If a package is available on multiple archives and one has higher
priority (as per `package-archive-priorities') only that one is
listed.  This can be configured with `package-menu-hide-low-priority'.

*** `package-menu-toggle-hiding' now toggles the hiding of packages.
This includes the above-mentioned low-priority packages, as well as
available packages whose version is lower than the currently installed
version (which were previously impossible to display).
This allows users to downgrade a package if a lower version is
available.

*** When filtering the package menu, keywords starting with "arc:" or
"status:" represent package archive or status, respectively, instead
of actual keywords.

*** Most functions which involve downloading information now take an
ASYNC argument.  If it is non-nil, package.el performs the download(s)
asynchronously.

*** New variable `package-menu-async' controls whether the
package-menu uses asynchronous downloads.

*** `package-install-from-buffer' and `package-install-file' work on directories.
This follows the same rules as installing from a .tar file, except the
-pkg file is optional.

*** Packages which are dependencies of other packages cannot be deleted.
The FORCE argument to `package-delete' overrides this.

*** New custom variable `package-selected-packages' tracks packages
which were installed by the user (as opposed to installed as
dependencies).  This variable can also be manually customized.

*** New command `package-install-user-selected-packages' installs all
packages from `package-selected-packages' which are currently missing.

*** New command `package-autoremove' removes all packages which were
installed strictly as dependencies but are no longer needed.

** Shell

When you invoke `shell' interactively, the *shell* buffer will now
display in a new window.  However, you can customize this behavior via
the `display-buffer-alist' variable.  For example, to get
the old behavior -- *shell* buffer displays in current window -- use
(add-to-list 'display-buffer-alist
     '("^\\*shell\\*$" . (display-buffer-same-window))).

** EIEIO
+++
*** The `:protection' slot option is not obeyed any more.
+++
*** The `newname' argument to constructors is optional&deprecated.
If you need your objects to be named, do it by inheriting from `eieio-named'.
+++
*** The <class>-list-p and <class>-child-p functions are declared obsolete.
+++
*** The <class> variables are declared obsolete.
+++
*** The <initarg> variables are declared obsolete.
*** defgeneric and defmethod are declared obsolete.
+++
*** `constructor' is now an obsolete alias for `make-instance'.

** ido
*** New command `ido-bury-buffer-at-head' bound to C-S-b
Bury the buffer at the head of `ido-matches', analogous to how C-k
kills the buffer at head.
*** A prefix argument to `ido-restrict-to-matches' will reverse its
meaning, and the list is restricted to those elements that do not
match the current input.

** Minibuffer

*** You can use <up> and <down> keys to move point in the multi-line
minibuffer just as in an ordinary buffer.  Only when point moves over
the bottom/top of the minibuffer it goes to the next/previous history
element.  The new commands bound to <up> and <down> in the minibuffer:
`next-line-or-history-element' and `previous-line-or-history-element'.

** Search and Replace

+++
*** New user option `search-default-regexp-mode'
specifies the default mode for I-search.

+++
*** `isearch' and `query-replace' can now perform character folding in matches.
Isearch does that by default, while `query-replace' will do that if
the new variable `replace-character-fold' is customized to a non-nil
value.  This is analogous to case folding, but instead of disregarding
case variants, it disregards wider classes of distinctions between
similar characters.  (Case folding is a special case of character
folding.)  This means many characters in the search string will match
entire groups of characters instead of just themselves.

For instance, the " will match all variants of double quotes (like “
and ”), and the letter a will match all of its accented cousins, even
those composed of multiple characters, as well as many other symbols
like ℀, ℁, ⒜, and ⓐ.

+++
*** New function `character-fold-to-regexp' can be used
by searching commands to produce a regexp matching anything that
character-folds into STRING.

+++
*** The new M-s M-w key binding uses eww to search the web for the
text in the region.  The search engine to use for this is specified by
the customizable variable `eww-search-prefix'.

+++
*** Query-replace history is enhanced.
When query-replace reads the FROM string from the minibuffer, typing
`M-p' will now show previous replacements as "FROM SEP TO", where FROM
and TO are the original text and its replacement, and SEP is an arrow
string defined by the new variable `query-replace-from-to-separator'.
To select a prior replacement, type `M-p' until the desired
replacement appears in the minibuffer, and then exit the minibuffer by
typing RET.

** Calc
+++
*** If `quick-calc' is called with a prefix argument, insert the
result of the calculation into the current buffer.

+++
** In Edebug, you can now set the initial mode with C-x C-a C-m.  With
this you can tell Edebug not to stop at the start of the first
instrumented function.

** ElDoc
*** New minor mode `global-eldoc-mode'
*** `eldoc-documentation-function' now defaults to `ignore'
*** `describe-char-eldoc' displays information about character at point,
and can be used as a default value of `eldoc-documentation-function'.  It is
useful when, for example, one needs to distinguish various spaces (e.g. ] [,
] [, ] [, etc.) while using mono-spaced font.

** eww

---
*** HTML can now be rendered using variable-width fonts.

+++
*** A new command `F' (`eww-toggle-fonts') can be used to toggle
whether to use variable-pitch fonts or not.  The user can also
customize the `shr-use-fonts' variable.

+++
*** A new command `R' (`eww-readable') will try do identify the main
textual parts of a web page and display only that, leaving menus and
the like off the page.

---
*** You can now use several eww buffers in parallel by renaming eww
buffers you want to keep separate.

+++
*** Partial state of the eww buffers (the URIs and the titles of the
pages visited) is now preserved in the desktop file.

+++
*** `eww-after-render-hook' is now called after eww has rendered
the data in the buffer.

---
*** The `eww-reload' command now takes a prefix to not reload via
the net, but just use the local copy of the HTML.

+++
*** The DOM shr and eww uses has been changed to the general Emacs
xml.el/libxml2 DOM, and a new package dom.el has been added to
interact with this DOM.  See the Emacs Lisp manual for interface
details.

+++
*** `mailcap-mime-data' is now consulted when displaying PDF files.

+++
*** The new `S' command will list all eww buffers, and allow managing
them.

---
*** https pages with valid certificates have headers marked in green, while
invalid certificates are marked in red.

** Message mode

*** text/html messages that contain inline image parts will be
transformed into multipart/related messages before sending.

** pcase
*** New UPatterns `quote', `app', `cl-struct', and `eieio'.
*** New UPatterns can be defined with `pcase-defmacro'.
+++
*** New vector QPattern.

** Lisp mode
*** Strings after `:documentation' are highlighted as docstrings.

** Rectangle editing
*** Rectangle Mark mode can have corners past EOL or in the middle of a TAB.
*** C-x C-x in rectangle-mark-mode now cycles through the four corners.
*** `string-rectangle' provides on-the-fly preview of the result.

** New font-lock functions font-lock-ensure and font-lock-flush, which
should be used instead of font-lock-fontify-buffer when called from Elisp.

** Macro `minibuffer-with-setup-hook' takes (:append FUN) to mean
appending FUN to `minibuffer-setup-hook'.

** cl-lib
*** New functions cl-fresh-line, cl-digit-char-p and cl-parse-integer.

** Calendar and diary

+++
*** The default `diary-file' is now located in .emacs.d.

+++
*** New commands to insert diary entries with Chinese dates:
`diary-chinese-insert-anniversary-entry' `diary-chinese-insert-entry'
`diary-chinese-insert-monthly-entry', `diary-chinese-insert-yearly-entry'.

+++
*** The calendar can now list and mark diary entries with Chinese dates.
See `diary-chinese-list-entries' and `diary-chinese-mark-entries'.

---
*** The option `calendar-mode-line-format' can now be nil,
which means to do nothing special with the mode line in calendars.

+++
*** New option `calendar-weekend-days'.
The option customizes which day headers receive the
`calendar-weekend-header' face.

---
*** New optional args N and STRING for ‘holiday-greek-orthodox-easter’.

---
*** Many items obsolete since at least version 23.1 have been removed.
The majority were function/variable/face aliases, too numerous to list here.
The remainder were:

**** Functions `calendar-one-frame-setup', `calendar-only-one-frame-setup',
`calendar-two-frame-setup', `european-calendar', `american-calendar'.

**** Hooks `cal-menu-load-hook', `cal-x-load-hook'.

**** Macro `calendar-for-loop'.

**** Variables `european-calendar-style', `diary-face', `hebrew-holidays-{1,4}'.

**** The nil and list forms of `diary-display-function'.

** New ERT function `ert-summarize-tests-batch-and-exit'.

** New js.el option `js-indent-first-init'.

---
** `Info-fontify-maximum-menu-size' can be t for no limit.

+++
** `info-display-manual' can now be given a prefix argument which (any
non-nil value) directs the command to limit the completion
alternatives to currently visited manuals.

---
** ntlm.el has support for NTLM2.

** Rmail

*** The Rmail commands d, C-d and u take optional repeat counts to delete or
undelete multiple messages.

*** Rmail can now render HTML mail messages if your Emacs was built with
libxml2 or if you have the Lynx browser installed.  By default, Rmail
will display the HTML version of a mail message that has both HTML and
plain text parts, if display of HTML email is possible; customize the
`rmail-mime-prefer-html' option to `nil' if you don't want that.

+++
*** In the commands that make summaries by subject, recipients, or senders,
you can no longer use commas to separate regular expressions.

** SES now supports local printer functions; see `ses-define-local-printer'.

** sh-script
*** In sh-mode you can now use `sh-shell' as a file-local variable to
specify the type of shell in use (bash, csh, etc).

*** New value `always' for sh-indent-after-continuation.
This provides old-style ("dumb") indentation of continued lines.

** TLS
---
*** Fatal TLS errors are now silent by default.

** URL

*** The URL package accepts now the protocols "ssh", "scp" and "rsync".
When `url-handler-mode' is enabled, file operations for these
protocols as well as for "telnet" and "ftp" are passed to Tramp.

*** The URL package allows customizing the `url-user-agent' string.
The new `url-user-agent' variable can be customized to be a string or
a function.

*** The new interface variable `url-request-noninteractive' can be used
to specify that we're running in a noninteractive context, and that
we should not be queried about things like TLS certificate validity.

*** If URL is used with a https connection, the first callback argument
plist will contain a :peer element that has the output of
`gnutls-peer-status' (if Emacs is built with GnuTLS support).

** Tramp

+++
*** New connection method "afp", which allows to access Mac OS X
volumes via the Apple Filing Protocol.

+++
*** New connection method "nc", which allows to access dumb busyboxes.

+++
*** Method-specific parameters can be overwritten now with variable
`tramp-connection-properties'.

---
*** Handler for `file-notify-valid-p' for remote machines that support
filesystem notifications.

** SQL mode

*** New user variable `sql-default-directory' enables remote
connections using Tramp.

*** New command `sql-send-line-and-next' sends the current line to the
interactive buffer and advances to the next line, skipping whitespace
and comments.

*** Add support for Vertica SQL.

** VC and related modes

*** Basic push support, via `vc-push', bound to `C-x v P'.
Implemented for Bzr, Git, Hg.  As part of this change, the pre-existing
(undocumented) command vc-hg-push now behaves slightly differently.

*** The new command vc-region-history shows the log+diff of the active region.

+++
*** You can refresh the VC state of a file buffer with `M-x vc-refresh-state'.
This command is useful when you perform version control commands
outside Emacs (e.g., from the shell prompt), or if you switch the VC
back-end for the buffer's file, or remove it from version control.

*** New option `vc-annotate-background-mode' controls whether
the color range from `vc-annotate-color-map' is applied to the
background or to the foreground.

*** `compare-windows' now compares text with the most recently used window
instead of the next window.  The new option `compare-windows-get-window-function'
allows to customize this.

*** Two new faces `compare-windows-removed' and `compare-windows-added'
replace the obsolete face `compare-windows'.

---
*** `log-edit-insert-changelog' converts "(tiny change)" to
"Copyright-paperwork-exempt: yes".  Set `log-edit-rewrite-tiny-change'
nil to disable this.

** VHDL mode supports VHDL'08.

** Calculator: decimal display mode uses "," groups, so it's more
fitting for use in money calculations; factorial works with
non-integer inputs.

** HideIfDef mode now support full C/C++ expressions, argumented macro expansions,
interactive macro evaluation and automatic scanning of #defined symbols.

*** New custom variable `hide-ifdef-header-regexp' to define C/C++ header file
name patterns.  Default case-insensitive .h, .hh, .hpp, .hxx, and .h++.
*** New custom variable `hide-ifdef-expand-reinclusion-protection' to prevent
reinclusion protected header files from being fully hidden.
*** New custom variable `hide-ifdef-exclude-define-regexp' to define symbol
name patterns (e.g. all "FOR_DOXYGEN_ONLY_*") to be excluded.

** TeX mode

*** New custom variable `tex-print-file-extension' to help users who
use PDF instead of DVI.

*** TeX mode now supports Prettify Symbols mode.  When enabling
`prettify-symbols-mode' in a tex-mode buffer, \alpha ... \omega, and
many other math macros are displayed using unicode characters.

** whitespace-mode: new 'big-indent style highlighting too much indentation.
By default, 32 spaces and four TABs are considered to be too much but
`whitespace-big-indent-regexp' can be configured to change that.

** tildify: `tildify-space-string', `tildify-pattern', and
`tildify-foreach-region-function' variables added making
`tildify-string-alist', `tildify-pattern-alist', and
`tildify-ignored-environments-alist' variables (as well as a few
helper functions) obsolete.

** xref
The new package provides generic framework and new commands to find
and move to definitions, as well as pop back to the original location.

*** New key bindings
`xref-find-definitions' replaces `find-tag' and provides an interface
to pick one destination among several.  Hence, `tags-loop-continue' is
unbound.  `xref-pop-marker-stack' replaces `pop-tag-mark', but uses an
easier binding, which is now unoccupied (`M-,').
`xref-find-definitions-other-window' replaces `find-tag-other-window'.
`xref-find-definitions-other-frame' replaces `find-tag-other-frame'.
`xref-find-apropos' replaces `find-tag-regexp'.

*** New variables
`find-tag-marker-ring-length' is now an obsolete alias for
`xref-marker-ring-length'.  `find-tag-marker-ring' is now an obsolete
alias for a private variable.  `xref-push-marker-stack' and
`xref-pop-marker-stack' should be used to mutate it instead.

** etags
As a result of the above, these commands are now obsolete:
`find-tag-other-window', `find-tag-other-frame', `find-tag-regexp',
`tags-apropos' and `tags-loop-continue'.

** EUDC
EUDC's LDAP backend has been improved.

*** EUDC supports LDAP-over-SSL URLs (ldaps://).

*** EUDC passes LDAP passwords through a pipe to the ldapsearch
subprocess instead of on the command line.

*** EUDC handles LDAP wildcards automatically so the user shouldn't
need to configure this manually anymore.

*** The LDAP configuration section of EUDC's manual has been
rewritten.

There have also been customization changes.

*** New custom variable `eudc-server-hotlist' to allow specifying
multiple EUDC servers in init file.

*** Custom variable `eudc-inline-query-format' defaults to completing
on email and firstname instead of surname.

*** Custom variable `eudc-expansion-overwrites-query' defaults to nil
to avoid interfering with the kill ring.

*** Custom variable `eudc-inline-expansion-format' defaults to
"Firstname Surname <mail-address>".

*** Custom variable `eudc-options-file' defaults to
"~/.emacs.d/eudc-options".

*** New custom variable `ldap-ldapsearch-password-prompt-regexp' to
allow overriding the regular expression that recognizes the ldapsearch
command line's password prompt.

EUDC's BBDB backend now supports BBDB 3.

EUDC's PH backend (eudcb-ph.el) is obsolete.

** Eshell

+++
*** The new built-in command `clear' can scroll window contents out of sight.
If provided with an optional non-nil argument, the scrollback contents will be cleared.

*** New buffer syntax '#<buffer-name>', which is equivalent to
'#<buffer buffer-name>'.  This shorthand makes interacting with
buffers from eshell more convenient.  Custom variable
`eshell-buffer-shorthand', which has been broken for a while, has been
removed.

*** By default, eshell "visual" program buffers (created by
`eshell-visual-commands' and similar custom vars) are no longer killed
when their processes die.  This fixes issues with short-lived commands
and makes visual programs more useful in general.  For example, if
"git log" is a visual command, it will always show the visual command
buffer, even if the "git log" process dies.  For the old behavior,
make the new option `eshell-destroy-buffer-when-process-dies' non-nil.

** Browse-url

*** Support for the Conkeror web browser.

---
*** Support for several ancient browsers is now officially obsolete.

+++
** tar-mode: new `tar-new-entry' command, allowing for new members to
be added to the archive.

---
** Autorevert: dired buffers are also auto-reverted via file
notifications, if Emacs is compiled with file notification support.

** File Notifications

+++
*** The new event `stopped' signals, that a file notification watch is
not active any longer.

+++
*** The new function `file-notify-valid-p' checks, whether a file
notification descriptor still corresponds to an activate watch.

** Dired

+++
*** The command `dired-do-compress' bound to `Z' now can compress
directories and decompress zip files.

+++
*** New command `dired-do-compress-to' bound to `c' can be used to
compress many marked files into a single named archive.  The
compression command is determined from the new
`dired-compress-files-alist' variable.

** Tabulated List Mode

+++
*** It is now safe for a mode that derives `tabulated-list-mode' to not
call `tabulated-list-init-header', in which case it will have no
header.

+++
*** `tabulated-list-print' takes a second optional argument, update,
which specifies an alternative printing method which is faster when
few or no entries have changed.

** Obsolete packages

---
*** gulp.el

*** landmark.el (moved to elpa.gnu.org)

\f
* New Modes and Packages in Emacs 25.1

** pinentry.el allows GnuPG passphrase to be prompted through the
minibuffer instead of a graphical dialog, depending on whether the gpg
command is called from Emacs (i.e., INSIDE_EMACS environment variable
is set).  This feature requires newer versions of GnuPG (2.1.5 or
later) and Pinentry (0.9.5 or later).

** cl-generic.el provides CLOS-style multiple-dispatch generic functions.

** scss-mode (a minor variant of css-mode)

** let-alist is a new macro (and a package) that allows one to easily
let-bind the values stored in an alist.

** `tildify-mode' allows to automatically insert hard spaces as one
types the text.  Breaking line after a single-character words is
forbidden by Czech and Polish typography (and may be discouraged in
other languages), so `auto-tildify-mode' makes it easier to create
a typographically-correct documents.

** The `seq' library adds sequence manipulation functions and macros
that complement basic functions provided by subr.el.  All functions
are prefixed with `seq-' and work on lists, strings and vectors.

** The `map' library provides map-manipulation functions that work on
alists, hash-table and arrays.  All functions are prefixed with
`map-'.

** The `thunk' library provides functions and macros to control the
evaluation of forms.

** js-jsx-mode (a minor variant of js-mode) provides indentation
support for JSX, an XML-like syntax extension to ECMAScript.

\f
* Incompatible Lisp Changes in Emacs 25.1

---
** `setq' and `setf' must now be called with an even number of
arguments.  The earlier behavior of silently supplying a nil to the
last variable when there was an odd number of arguments has been
eliminated.

** `syntax-begin-function' is declared obsolete.
Removed font-lock-beginning-of-syntax-function and the SYNTAX-BEGIN
slot in font-lock-defaults.

+++
** `package-initialize' now sets `package-enable-at-startup' to nil if
called during startup.  Users who call this function in their init
file and still expect it to be run after startup should set
`package-enable-at-startup' to t after the call to
`package-initialize'.

** `:global' minor mode use `setq-default' rather than `setq'.
This means that you can't use `make-local-variable' and expect them to
"magically" become buffer-local.

** `inhibit-point-motion-hooks' now defaults to t and is obsolete.

+++
** `track-mouse' no longer freezes the shape of the mouse pointer.
The `track-mouse' form no longer refrains from changing the shape of
the mouse pointer for the entire time the body of that form is
executed.  Lisp programs that use `track-mouse' for dragging across
large portions of the Emacs display, and want to avoid changes in the
pointer shape during dragging, should bind the variable `track-mouse'
to the special value `dragging' in the body of the form.

---
** The optional `predicate' argument of `lisp-complete-symbol' no longer
has any effect.  (This change was made in Emacs 24.4 but was not
advertised at the time.)

** `indirect-function' does not signal `void-function' any more.
This is mostly a bug-fix, since this change was missed back in 24.4 when
symbol-function was changed not to signal `void-function' any more.

*** As a consequence, the second arg of `indirect-function' is now obsolete.

** Comint, term, and compile do not set the EMACS env var any more.
Use the INSIDE_EMACS environment variable instead.

** `save-excursion' does not save&restore the mark any more.

** read-buffer-function can now be called with a 4th argument (`predicate').

** completion-table-dynamic stays in the minibuffer.
If you want the old behavior of calling the function in the buffer
from which the minibuffer was entered, call it with the new argument
`switch-buffer'.

** window-configurations no longer record the buffers' marks.

** inhibit-modification-hooks now also inhibits lock-file checks, as well as
active region handling.

** deactivate-mark is now buffer-local.

** `cl-the' now asserts that its argument is of the given type.

** `process-running-child-p` may now return a numeric process
group ID instead of `t'.

+++
** Mouse click events on mode line or header line no longer include
any reference to a buffer position.  The 6th member of the mouse
position list returned for such events is now nil.

** Menu items in keymaps do not support the "key shortcut cache" any more.
These slots used to hold key-shortcut data, but have been obsolete since
Emacs-21.

** Emacs no longer downcases the first letter of a system diagnostic
when signaling a file error.  For example, it now reports "Permission
denied" instead of "permission denied".  The old behavior was problematic
in languages like German where downcasing rules depend on grammar.

+++
** New variable ‘text-quoting-style’ to control how Emacs translates quotes.
Set it to ‘curve’ for curved single quotes ‘like this’, to ‘straight’
for straight apostrophes 'like this', and to ‘grave’ for grave accent
and apostrophe `like this'.  The default value nil acts like ‘curve’
if curved single quotes are displayable, and like ‘grave’ otherwise.
The new variable affects display of diagnostics and help, but not of info.

+++
** substitute-command-keys now replaces quotes.
That is, it converts documentation strings’ quoting style as per the
value of ‘text-quoting-style’.  Doc strings in source code can use
either curved single quotes or grave accents and apostrophes.  As
before, characters preceded by \= are output as-is.

+++
** Message-issuing functions ‘error’, ‘message’, etc. now convert quotes.
They use the new ‘format-message’ function instead of plain ‘format’,
so that they now follow user preference as per ‘text-quoting-style’
when processing curved single quotes, grave accents, and apostrophes
in their format argument.

+++
** The character classes [:alpha:] and [:alnum:] in regular expressions
now match multibyte characters using Unicode character properties.
If you want the old behavior where they matched any character with
word syntax, use `\sw' instead.

+++
** The character classes [:graph:] and [:print:] in regular expressions
no longer match every multibyte character.  Instead, Emacs now
consults the Unicode character properties to determine which
characters are graphic or printable.  In particular, surrogates and
unassigned codepoints are now rejected.  If you want the old behavior,
use [:multibyte:] instead.

+++
** The `diff' command uses the unified format now.  To restore the old
behavior, set `diff-switches' to `-c'.

** `grep-template' and `grep-find-template' values don't include the
--color argument anymore.  It's added at the <C> place holder position
dynamically.  Any third-party code that changes these templates should
be updated accordingly.

+++
** ‘(/ N)’ is now equivalent to ‘(/ 1 N)’ rather than to ‘(/ N 1)’.
The new behavior is compatible with Common Lisp and with XEmacs.
This change does not affect Lisp code intended to be portable to
Emacs 24.2 and earlier, which did not support unary ‘/’.

+++
** The `default-directory' value doesn't have to end slash.  To make
that happen, `unhandled-file-name-directory' now defaults to calling
`file-name-as-directory'.

\f
* Lisp Changes in Emacs 25.1

** syntax-propertize is now automatically called on-demand during forward
parsing functions like `forward-sexp'.

** New hooks prefix-command-echo-keystrokes-functions and
prefix-command-preserve-state-hook, to allow the definition of prefix
commands other than the predefined C-u.

** New functions `filepos-to-bufferpos' and `bufferpos-to-filepos'.

** The default value of `load-read-function' is now `read'.

** New hook `pre-redisplay-functions', a bit easier to use than pre-redisplay-function.

** The second arg of `looking-back' should always be provided explicitly.

** Obsolete text properties `intangible', `point-entered', and `point-left'.
Replaced by properties `cursor-intangible' and `cursor-sensor-functions',
implemented by the new `cursor-intangible-mode' and
`cursor-sensor-mode' minor modes.

** New process type `pipe', which can be used in combination with the
`:stderr' keyword of make-process to handle standard error output
of subprocess.

** New function `make-process' provides an alternative interface to
`start-process'.  It allows programs to set process parameters such as
process filter, sentinel, etc., through keyword arguments (similar to
`make-network-process').

+++
** A new function `directory-files-recursively' returns all matching
files (recursively) under a directory.

+++
** New variable `inhibit-message', when bound to non-nil, inhibits
`message' and related functions from displaying messages the Echo
Area.  The output is still logged to the *Messages* buffer.

+++
** A new text property `inhibit-read-only' can be used in read-only
buffers to allow certain parts of the text to be writable.

** `read-buffer' takes a new `predicate' argument.

** Emacs Lisp now supports generators.

** New finalizer facility for running code when objects
   become unreachable.

** lexical closures can use (:documentation <form>) to build their docstring.
It should be placed right where the docstring would be, and <form> is then
evaluated (and should return a string) when the closure is built.

** define-inline provides a new way to define inlinable functions.

** New function `macroexpand-1' to perform a single step of macroexpansion.

** Some "x-*" were obsoleted:
*** x-select-text is renamed gui-select-text.
*** x-selection-value is renamed gui-selection-value.
*** x-get-selection is renamed gui-get-selection.
*** x-get-clipboard and x-clipboard-yank are marked obsolete.
*** x-get-selection-value is renamed to gui-get-primary-selection.
*** x-set-selection is renamed to gui-set-selection

** New function `string-greaterp', which return the opposite result of
`string-lessp'.

+++
** The new functions `string-collate-lessp' and `string-collate-equalp'
preserve the collation order as defined by the system's locale(1)
environment.  For the time being this is implemented for modern POSIX
systems and for MS-Windows, for other systems they fall back to their
counterparts `string-lessp' and `string-equal'.

---
*** The ls-lisp package uses `string-collate-lessp' to sort file names.
If you want the old, locale-independent sorting, customize the new
option `ls-lisp-use-string-collate' to a nil value.

+++
*** The MS-Windows specific variable `w32-collate-ignore-punctuation',
if set to a non-nil value, causes the above 2 functions to ignore
symbol and punctuation characters when collating strings.  This
emulates the behavior of modern Posix platforms when the locale's
codeset is "UTF-8" (as in "en_US.UTF-8").  This is needed because
MS-Windows doesn't support UTF-8 as codeset in its locales.

** New function `alist-get', which is also a valid place (aka lvalue).

** New function `funcall-interactively', which works like `funcall'
but makes `called-interactively-p' treat the function as (you guessed it)
called interactively.

** New function `function-put' to use instead of `put' for function properties.

+++
** The new function `bidi-find-overridden-directionality' allows to
find characters whose directionality was, perhaps maliciously,
overridden by directional override control characters.  Lisp programs
can use this to detect potential phishing of URLs and other links that
exploits bidirectional display reordering.

+++
** The new function `buffer-substring-with-bidi-context' allows to
copy a portion of a buffer into a different location while preserving
the visual appearance both of the copied text and the text at
destination, even when the copied text includes mixed bidirectional
text and directional control characters.

+++
** New properties that can be specified with `declare':
*** (interactive-only INSTEAD), says to use INSTEAD for non-interactive use.
*** (pure VAL), if VAL is non-nil, indicates the function is pure.
*** (side-effect-free VAL), if VAL is non-nil, indicates the function does not
have side effects.

+++
** New macro `with-file-modes', for evaluating expressions with default file
permissions set to temporary values (e.g., for creating private files).

** You can access the slots of structures using `cl-struct-slot-value'.

** Function `sort' can deal with vectors.

** Function `system-name' now returns an updated value if the current
system's name has changed or if the Emacs process has changed systems,
and to avoid long waits it no longer consults DNS to canonicalize the
name.  The variable `system-name' is now obsolete.

+++
** Function `write-region' no longer outputs "Wrote FILE" in batch mode.

** If `pwd' is called with a prefix argument, insert the current default
directory at point.

+++
** New functions return extended information about fonts and faces.

+++
*** The function `font-info' now returns more details about a font.
In particular, it now returns the average width of the font's
characters, which can be used for geometry-related calculations.

+++
*** A new function `default-font-width' returns the average width of a
character in the current buffer's default font.  If the default face
is remapped (see `face-remapping-alist'), the value for the remapped
face is returned.  This function complements the existing function
`default-font-height'.

+++
*** New functions `window-font-height' and `window-font-width' return
the height and average width of characters in a specified face and
window.  If FACE is remapped (see `face-remapping-alist'), the
function returns the information for the remapped face.

+++
*** A new function `window-max-chars-per-line' returns the maximal
number of characters that can be displayed on one line.  If a face
and/or window are provided, these values are used for the
calculation.  This function is different from `window-body-width' in
that it accounts for (i) continuation glyphs, (ii) the size of the
font, and (iii) the specified window.

---
** New utilities in subr-x.el:
*** New macros `if-let' and `when-let' allow defining bindings and to
    execute code depending whether all values are true.
*** New macros `thread-first' and `thread-last' allow threading a form
    as the first or last argument of subsequent forms.

+++
** Documentation strings now support quoting with curved single quotes
‘like-this’ in addition to the old style with grave accent and
apostrophe `like-this'.  The new style looks better on today's displays.
In the new Electric Quote mode, you can enter curved single quotes
into documentation by typing ` and '.  Outside Electric Quote mode,
you can enter them by typing ‘C-x 8 [’ and ‘C-x 8 ]’, or (if your Alt
key works) by typing ‘A-[’ and ‘A-]’.  As described above under
‘text-quoting-style’, the user can specify how to display doc string
quotes.

+++
** New function ‘format-message’ is like ‘format’ and also converts
curved single quotes, grave accents and apostrophes as per
‘text-quoting-style’.

+++
** show-help-function's arg is converted via substitute-command-keys
before being passed to the function.  Help strings, help-echo
properties, etc. can therefore contain command key escapes and
quotation marks.

+++
** Time-related changes:

*** Time conversion functions now accept an optional ZONE argument
that specifies the time zone rules for conversion.  ZONE is omitted or
nil for Emacs local time, t for Universal Time, ‘wall’ for system wall
clock time, or a string as in ‘set-time-zone-rule’ for a time zone
rule.  The affected functions are ‘current-time-string’,
‘current-time-zone’, ‘decode-time’, and ‘format-time-string’.  The
function ‘encode-time’, which already accepted a simple time zone rule
argument, has been extended to accept all the new forms.

*** Time-related functions now consistently accept numbers
(representing seconds since the epoch) and nil (representing the
current time) as well as the usual list-of-integer representation.
Affected functions include `current-time-string', `current-time-zone',
`decode-time', `float-time', `format-time-string', `seconds-to-time',
`time-add', `time-less-p', `time-subtract', `time-to-day-in-year',
`time-to-days', and `time-to-seconds'.

*** The `encode-time-value' and `with-decoded-time-value' macros have
been obsoleted.

*** `calendar-next-time-zone-transition', `time-add', and
`time-subtract' no longer return time values in the obsolete and
undocumented integer-pair format.  Instead, they return a list of two
integers.

+++
** New function `set-binary-mode' allows to switch a standard stream
of the Emacs process to binary I/O mode.

+++
** The new function `directory-name-p' can be used to check whether a file
name (as returned from, for instance, `file-name-all-completions') is
a directory file name.  It returns non-nil if the last character in
the name is a directory separator character (forward slash on GNU and
Unix systems, forward- or backslash on MS-Windows and MS-DOS).

** ASCII approximations to curved quotes are put in standard-display-table
if the terminal cannot display curved quotes.

** Standard output and error streams now transliterate characters via
standard-display-table, and encode output using locale-coding-system.

+++
** New var `truncate-string-ellipsis' to choose how to indicate truncation.

+++
** New possible value for `system-type': `nacl'.
This is used by Google's Native Client (NaCl).

** Miscellaneous name change

For consistency with the usual Emacs spelling, the Lisp variable
`hfy-optimisations' has been renamed to `hfy-optimizations'.
The old name should still work, as an obsolescent alias.

\f
* Changes in Frames and Windows Code in Emacs 25.1

+++
** Emacs can now draw horizontal scroll bars on some platforms that
provide toolkit scroll bars, namely Gtk+, Lucid, Motif and Windows.
Horizontal scroll bars are turned off by default.
*** New function `horizontal-scroll-bars-available-p' telling whether
    horizontal scroll bars are available on the underlying system.
*** New mode `horizontal-scroll-bar-mode' to toggle horizontal scroll
    bars on all existing and future frames.
*** New function `toggle-horizontal-scroll-bar' to toggle horizontal
    scroll bars on the selected frame.
*** New frame parameters `horizontal-scroll-bars' and
    `scroll-bar-height' to set horizontal scroll bars and their height
    for individual frames and in `default-frame-alist'.
*** New functions `frame-scroll-bar-height' and
    `window-scroll-bar-height' return the height of horizontal scroll
    bars on a specific frame or window.
*** `set-window-scroll-bars' now accepts five parameters where the last
    two specify height and type of the window's horizontal scroll bar.
*** `window-scroll-bars' now returns type and sizes of horizontal scroll
    bars too.
*** New buffer-local variables `horizontal-scroll-bar' and
    `scroll-bar-height'.

+++
** New functions `frame-geometry' and `frame-edges' give access to a
frame's geometry.

+++
** New functions `mouse-absolute-pixel-position' and
`set-mouse-absolute-pixel-position' get/set screen coordinates of the
mouse cursor.

+++
** The function `window-edges' now accepts three additional arguments to
retrieve body, absolute and pixel edges of the window.

+++
** The functions `window-inside-edges', `window-inside-pixel-edges' and
`window-inside-absolute-pixel-edges' have been renamed to respectively
`window-body-edges', `window-body-pixel-edges' and
`window-absolute-body-pixel-edges'.  The old names are kept as aliases.

+++
** New function `window-absolute-pixel-position' to get the screen
coordinates of a visible buffer position.

+++
** The height of a frame's menu and tool bar are no longer counted in the
frame's text height.  This means that the text height stands only for
the height of the frame's root window plus that of the echo area (if
present).  This was already the behavior for frames with external tool
and menu bars (like in the Gtk builds) but has now been extended to all
builds.

+++
** Frames now do not necessarily preserve the number of columns or lines
they display when setting default font, menu bar, fringe width, or
scroll bars.  In particular, maximized and fullscreen frames are
conceptually never resized if such settings change.  For fullheight and
fullwidth frames, the behavior may depend on the toolkit used.
*** New option `frame-inhibit-implied-resize' if non-nil, means that
   setting default font, menu bar, fringe width, or scroll bars of a
   specific frame does not resize that frame in order to preserve the
   number of columns or lines it displays.

+++
** New function `window-preserve-size' allows to preserve the size of
windows without "fixing" it.  It's supported by `fit-window-to-buffer',
`temp-buffer-resize-mode' and `display-buffer'.

+++
** New minor mode `window-divider-mode' and options
`window-divider-default-places', `window-divider-default-bottom-width'
and `window-divider-default-right-width'.

+++
** New option `switch-to-buffer-in-dedicated-window' allows to customize
how `switch-to-buffer' proceeds interactively when the selected window
is strongly dedicated to its buffer.

+++
** The option `even-window-heights' has been renamed to
`even-window-sizes' and now handles window widths as well.

** Tearoff menus and detachable toolbars for Gtk+ has been removed.
Those features have been deprecated in Gtk+ for a long time.

** Etags

*** etags no longer qualifies class members by default.

By default, `etags' will not qualify class members for C-like
object-oriented languages with their class names and namespaces, and
will remove qualifications used explicitly in the code from the tag
names it puts in TAGS files.  This is so the etags.el back-end for
`xref-find-definitions' is more accurate and produces less false
positives.

Use --class-qualify (-Q) if you want the old default behavior of
qualifying class members in C++, Java, and Objective C.  Note that
using -Q might make some class members become "unknown" to `M-.'
(`xref-find-definitions'); if so, you can use `C-u M-.' to specify the
qualified names by hand.

*** New language Ruby

Names of modules, classes, methods, and functions are tagged.
Overloaded operators are also tagged.

*** Improved support for Lua

Etags now tags functions even if the "function" keyword follows some
whitespace at line beginning.

\f
* Changes in Emacs 25.1 on Non-Free Operating Systems

---
** MS-Windows specific Emacs build scripts are no longer in the distribution
This includes the makefile.w32-in files in various subdirectories, and
the support files.  The file nt/configure.bat now just tells the user
to use the procedure described in nt/INSTALL, by running the Posix
`configure' script in the top-level directory.

---
** Building Emacs for MS-Windows requires at least Windows XP
or Windows Server 2003.  The built binaries still run on all versions
of Windows starting with Windows 9X.

+++
** Emacs running on MS-Windows now supports the daemon mode.

** The byte counts in etags-generated TAGS files are now the same on
MS-Windows as they are on other platforms.

---
** On OS X, configure creates a Cocoa ("Nextstep") build by default.
Pass '--without-ns' to configure to create an X11 build, the old default.

** OS X 10.5 or older is no longer supported.

** OS X on PowerPC is no longer supported.

---
** New variable `ns-use-fullscreen-animation' controls animation for
non-native NS fullscreen.  The default is nil.  Set to t to enable
animation when entering and leaving fullscreen.  For native OSX fullscreen
this has no effect.

---
** The new function 'w32-application-type' returns the type of an
MS-Windows application given the name of its executable program file.
