** The configure option '--enable-silent-rules' and the command
'make V=0' now do a better job of suppressing chatter.
+---
+** 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.

* Startup Changes in Emacs 25.1
\f
* Changes in Emacs 25.1
+** New function `custom-prompt-customize-unsaved-options' checks for
+unsaved customizations and prompts user to customize (if found).
+
++++
** 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.
+---
** The new M-s M-w key binding uses eww to search the web for the
text in the region.
systems and for MS-Windows, for other systems they fall back to their
counterparts `string-lessp' and `string-equal'.
-+++
-** 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 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.
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.
++++
+** 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 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
to all the files and subdirectories of a directory, similarly to the C
library function `ftw'.
+** 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
+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 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.
+
+** 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.
+
\f
* Editing Changes in Emacs 25.1
and the Bidirectional Parentheses Algorithm (BPA) specified by these
Unicode standards.
+** You can access `mouse-buffer-menu' (C-down-mouse-1) using C-f10.
+
\f
* Changes in Specialized Modes and Packages in Emacs 25.1
+
+** EIEIO
+*** The <class>-list-p and <class>-child-p functions are declared obsolete.
+*** The <class> variables are declared obsolete.
+*** The <initarg> variables are declared obsolete.
** 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
** eww
++++
*** 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
** cl-lib
*** New functions cl-fresh-line, cl-digit-char-p and cl-parse-integer.
+** seq
+*** New seq library:
+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.
+
** Calendar and diary
+++
** 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).
+** TLS
+---
+*** Fatal TLS errors are now silent by default.
+
** URL
*** The URL package accepts now the protocols "ssh", "scp" and "rsync".
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 "nc", which allows to access dumb busyboxes.
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.
+
** Calculator: decimal display mode uses "," groups, so it's more
fitting for use in money calculations; factorial works with
non-integer inputs.
* New Modes and Packages in Emacs 25.1
** 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.
+
\f
* Incompatible Lisp Changes in Emacs 25.1
+** 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's marks.
** inhibit-modification-hooks now also inhibits lock-file checks, as well as
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'.
+
** Tearoff menus and detachable toolbars for Gtk+ has been removed.
Those features have been deprecated in Gtk+ for a long time.
