** 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 '--enable-silent-rules' and the command
-'make V=0' now do a better job of suppressing chatter.
+** 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 `grep-changelog' script (and its manual page) are no longer included.
\f
* Changes in Emacs 25.1
+** `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.
+
** New function `custom-prompt-customize-unsaved-options' checks for
unsaved customizations and prompts user to customize (if found).
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.
+

** The new function `bidi-find-overridden-directionality' allows to
find characters whose directionality was, perhaps maliciously,
destination, even when the copied text includes mixed bidirectional
text and directional control characters.
-*** The ls-lisp package uses `string-collate-lessp' to sort file names.
-If you want the old, locale-independent sorting, customize the new

** 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
** A new text property `inhibit-read-only' can be used in read-only
buffers to allow certain parts of the text to be writable.
-** A new function `file-tree-walk' allows to apply a certain action
-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.
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
+** Unicode names entered via C-x 8 RET now use substring completion by default.
+
** New minor mode global-eldoc-mode is enabled by default.
** Emacs now supports "bracketed paste mode" when running on a terminal
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
+** 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.
** 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
---
** `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.
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
+*** `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'.
+
** Calculator: decimal display mode uses "," groups, so it's more
fitting for use in money calculations; factorial works with
non-integer inputs.
`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'.
+
** Obsolete packages

\f
* New Modes and Packages in Emacs 25.1
+** 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.
\f
* Incompatible Lisp Changes in Emacs 25.1
** 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.
+
---
** New utilities in subr-x.el:
*** New macros `if-let' and `when-let' allow defining bindings and to
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.
+
\f
* Changes in Frames and Windows Code in Emacs 25.1
`scroll-bar-height'.
+++
-** The height of a frame's menu and tool bar are no more counted in the
+** 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
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.
