+** New configure option ‘--disable-build-details’ attempts to build an
+Emacs that is more likely to be reproducible; that is, if you build
+and install Emacs twice, the second Emacs is a copy of the first.
+Deterministic builds omit the build date from the output of the
+emacs-version and erc-cmd-SV functions, and the leave the following
+variables nil: emacs-build-system, emacs-build-time,
+erc-emacs-build-time.

+** `align-regexp' has a separate history for its interactive argument
+`align-regexp' no longer shares its history with all other
+history-less functions that use `read-string'

** The networking code has been reworked so that it's more
asynchronous than it was (when specifying :nowait t in
until they have changed status to "run". This is most easily done
from a process sentinel.
+** `make-network-stream' has always allowed :service to be specified
+as a "number string" (i.e., :service "993") when using gethostbyname,
+but has required using a real number (i.e., :service 993) on systems
+without gethostbyname. This difference has now been eliminated, and
+you can use "number strings" on all systems.

** It is possible to disable attempted recovery on fatal signals
Two new variables allow to disable attempts to recover from stack
** Autoload files can be generated without timestamps,
by setting `autoload-timestamps' to nil.
+FIXME As an experiment, nil is the current default.
+If no insurmountable problems before next release, it can stay that way.
** `ert-with-function-mocked' of 'ert-x package allows mocking of functions
in unit tests.

* Changes in Emacs 25.2 on Non-Free Operating Systems
+** Intercepting hotkeys on Windows 7 and later now works better.
+The new keyboard hooking code properly grabs system hotkeys such as
+Win-* and Alt-TAB, in a way that Emacs can get at them before the
+system. This makes the `w32-register-hot-key' functionality work
+again on all versions of MS-Windows starting with Windows 7. On
+Windows NT and later you can now register any hotkey combination. (On
+Windows 9X, the previous limitations, spelled out in the Emacs manual,
+still apply.)

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

-** The `save-place' variable is replaced by `save-place-mode'.
+** The way to turn on and off `save-place' mode has changed.
+It is no longer sufficient to load the saveplace library and set
+`save-place' non-nil. Instead, use the two new minor modes:
+`save-place-mode' turns on saving last place in every file, and
+`save-place-local-mode' does that only for the file in whose buffer it
+is invoked. The `save-place' variable is now an obsolete alias for
+`save-place-mode', which replaces it, and `toggle-save-place' is an
+obsolete alias for the new `save-place-local-mode' command.
** ERC
*** New command `package-install-selected-packages' installs all
packages from `package-selected-packages' which are currently missing.
+---
+*** `package-install' function now takes a DONT-SELECT argument. If
+this function is called interactively or if DONT-SELECT is nil, add the
+package being installed to `package-selected-packages'.
+
---
*** New command `package-autoremove' removes all packages which were
installed strictly as dependencies but are no longer needed.
textual parts of a web page and display only that, leaving menus and
the like off the page.
++++
+*** A new command `D' (`eww-toggle-paragraph-direction') allows you to
+toggle the paragraph direction between left-to-right and right-to-left.
+
---
*** Images that are being loaded are now marked with grey
"placeholder" images of the size specified by the HTML. They are then
to specify that we're running in a noninteractive context, and that
we should not be queried about things like TLS certificate validity.
+---
+*** `url-mime-accept-string' can now be used as in "interface"
+variable, meaning you can bind it around an `url-retrieve' call.
+
---
*** If URL is used with a https connection, the first callback argument
plist will contain a :peer element that has the output of
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.
+---
+*** The VC state indicator in the mode line now defaults to more
+colorful faces to make it more obvious to the user what the state is.
+See the `vc-faces' customization group.

*** New option `vc-annotate-background-mode' controls whether
the color range from `vc-annotate-color-map' is applied to the
compression command is determined from the new
`dired-compress-files-alist' variable.
++++
+*** In wdired, when editing files to contain slash characters,
+the resulting directories are automatically created. Whether
+to do this or not is controlled by the
+`wdired-create-parent-directories' variable.
+
+++
*** `W' is now bound to `browse-url-of-dired-file', and is useful for
viewing HTML files and the like.
dynamically. Any third-party code that changes these templates should
be updated accordingly.
+** The grep/rgrep/lgrep functions will now ask about saving files
+before running. This is controlled by the `grep-save-buffers'
+variable.
+
+++
** ‘(/ N)’ is now equivalent to ‘(/ 1 N)’ rather than to ‘(/ N 1)’.
The new behavior is compatible with Common Lisp and with XEmacs.
** New possible value for `system-type': `nacl'.
This is used by Google's Native Client (NaCl).
+---
+** `read-color' will now display the color names using the color itself
+as the background color.
+
+---
+** There is now a new variable `flyspell-sort-corrections-function'
+that allows changing the way corrections are sorted.
+
** Miscellaneous name change
