-The framework's API is still experimental and can change in major,
-backward-incompatible ways.
-
++++
*** 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.
+`xref-pop-marker-stack' should be used instead to manipulate the stack
+of searches for definitions.
---
*** `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').

** 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.

If provided with an optional non-nil argument, the scrollback contents will be cleared.

'#<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

minibuffer instead of a graphical dialog, depending on whether the gpg
command is called from Emacs (i.e., INSIDE_EMACS environment variable

+---
** 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-'.
+---

Removed font-lock-beginning-of-syntax-function and the SYNTAX-BEGIN
slot in font-lock-defaults.
`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

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.
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
** 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

`cursor-sensor-mode' minor modes.
+** `inhibit-point-motion-hooks' now defaults to t and is obsolete.
+
++++
** 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
** `read-buffer' takes a new `predicate' argument.
++++
** Emacs Lisp now supports generators.
+See the "Generators" section of the ELisp manual for the details.

evaluated (and should return a string) when the closure is built.
** define-inline provides a new way to define inlinable functions.
** New macro `with-file-modes', for evaluating expressions with default file
permissions set to temporary values (e.g., for creating private files).

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.
+To force a specific encoding, bind `coding-system-for-write' to the
+coding-system of your choice when invoking functions like `prin1' and
+`message'.
+++
** New var `truncate-string-ellipsis' to choose how to indicate truncation.
** 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.
*** 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.
+

bars on all existing and future frames.

`window-scroll-bar-height' return the height of horizontal scroll
bars on a specific frame or window.
+

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'.
** Etags
++++
*** etags no longer qualifies class members by default.
By default, `etags' will not qualify class members for C-like
(`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.
