* 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.

* Changes in Emacs 25.1
** A new function `directory-files-recursively' returns all matching
files (recursively) under a directory.
-** The new `directory-name-p' can be used to check whether a file
+** 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 forward slash.
** New possible value for `system-type': nacl.
++++
+** 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.
+
++++
+** 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.
+

* Editing Changes in Emacs 25.1
** 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”.
+
** New minor mode global-eldoc-mode is enabled by default.
** Emacs now supports "bracketed paste mode" when running on a terminal
\f
* Changes in Specialized Modes and Packages in Emacs 25.1
+
+** 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).
+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-hide-obsolete' 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.

undelete multiple messages.
-** Rmail can now render HTML mail messages if your Emacs was built with
+*** 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'.
** In sh-mode, you can now use `sh-shell' as a file-local variable to
** 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.
*** New option `vc-annotate-background-mode' controls whether
*** 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.
+** 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 and .hxx.
*** 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.
** 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.

* Incompatible Lisp Changes in Emacs 25.1
+** `inhibit-point-motion-hooks' now defaults to t and is obsolete.
+
+** 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.
from which the minibuffer was entered, call it with the new argument
`switch-buffer'.

denied" instead of "permission denied". The old behavior was problematic
in languages like German where downcasing rules depend on grammar.
+** (substitute-command-keys "`foo'") now returns "‘foo’".
+That is, it replaces grave accents by left single quotation marks, and
+apostrophes that match grave accents by right single quotation marks.
+As before, isolated apostrophes and characters preceded by \= are
+output as-is.

+++
** The character classes [:alpha:] and [:alnum:] in regular expressions
now match multibyte characters using Unicode character properties.
\f
* Lisp Changes in Emacs 25.1
+** 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.
** define-inline provides a new way to define inlinable functions.
-** New function macroexpand-1 to perform a single step of macroexpansion.

*** x-set-selection is renamed to gui-set-selection
+** New function `string-greaterp', which return the opposite result of
+`string-lessp'.

** New function `alist-get', which is also a valid place (aka lvalue).
** New function `funcall-interactively', which works like `funcall'
** You can access the slots of structures using `cl-struct-slot-value'.
-** Functions `rmail-delete-forward' and `rmail-delete-backward' take an
-optional repeat-count argument.
-
** Function `sort' can deal with vectors.
** Function `system-name' now returns an updated value if the current
+++
** 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 utilities in subr-x.el:
*** New macros `if-let' and `when-let' allow defining bindings and to
*** 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.
+When an old-style string is copied to a help buffer it is converted to
+the new style.
+
+++
** Time-related changes:
** New function `set-binary-mode' allows to switch a standard stream
of the Emacs process to binary I/O mode.
+** In locales that cannot display curved quotes, ASCII approximations
+are installed in standard-display-table.
+
+** Standard output and error streams now transliterate characters via
+standard-display-table, and encode output using locale-coding-system.
+
** Miscellaneous name change
For consistency with the usual Emacs spelling, the Lisp variable
windows without "fixing" it. It's supported by `fit-window-to-buffer',
`temp-buffer-resize-mode' and `display-buffer'.
++++
+** 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.
+
** Tearoff menus and detachable toolbars for Gtk+ has been removed.
Those features have been deprecated in Gtk+ for a long time.
+** Miscellaneous
+
+*** 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.
