** Emacs can be compiled with libxml2 support.
**** The command `mail-attach-file' was renamed to `mail-insert-file'.
The old name is now an obsolete alias to the new name.
++++
+*** You can type C-c m from M-x report-emacs-bug if you prefer, and if
+your system supports it, to transfer your report to your desktop's
+preferred mail client. This uses either the "xdg-email" utility, or

*** custom-buffer-sort-alphabetically now defaults to t.
+++
** ERC changes
-*** New vars `erc-autojoin-timing' and `erc-autojoin-delay'.
-If the value of `erc-autojoin-timing' is 'ident, ERC autojoins after a
-successful NickServ identification, or after `erc-autojoin-delay'
-seconds. The default value, 'ident, means to autojoin immediately
-after connecting.
+---
+*** New options `erc-autojoin-timing' and `erc-autojoin-delay',
+controlling attempts to autojoin a channel.
*** New variable `erc-coding-system-precedence': If we use `undecided'
as the server coding system, this variable will then be consulted.

+*** Product-specific SQL interactive commands now take prefix arguments.
These commands (`sql-sqlite', `sql-postgres', `sql-mysql', etc.),
given a prefix argument, prompt for a name for the SQL interactive
buffer. This reduces the need for calling `sql-rename-buffer'.

*** SQL interactive modes suppress command continuation prompts, and
replace tabs with spaces. The first change impacts multiple line SQL
statements entered with C-j between each line, statements yanked into
the buffer and statements sent with `sql-send-*' functions. The

*** New "Save Connection" menu item in SQLi buffers.
This gathers the login params specified for the SQLi session, if it
was not started by a connection, and saves them as a new connection.
-*** Commands for listing database objects and details.
-In an SQLi session, you can get a list of objects in the database.
-The contents of these lists are product specific.
-
-**** `C-c C-l a' or the "SQL->List all objects" menu item
-lists all the objects in the database. With a prefix argument, it
-displays additional details or extend the listing to include other
-schemas objects.
-
-**** `C-c C-l t' or the "SQL->List Table details" menu item
-prompts for the name of a database table or view and displays the list
-of columns in the relation. With a prefix argument, it displays
-additional details about each column.

of the header line.
-** A backquote not followed by a space is now always treated as new-style.
+---
+** Support for "old-style" backquotes, which have been obsolete for
+more than 10 years, has been further reduced. Now a backquote not
+followed by a space is always treated as a "new-style" backquote.
+Please consider completely removing all "old-style" backquotes from
+your code as a matter of some urgency. If your code uses backquotes
+as documented in the Elisp manual, and compiles without warning, then
+you have nothing to do in this regard. Code not following the
+appropriate conventions may fail to compile. The most common cause of
+trouble seems to be an old-style backquote followed by a newline.

** view-buffer now treats special mode-class in the same way that
view-file has since Emacs 22 (ie, it won't enable View mode if the
major-mode is special).
-** Passing a nil argument to a minor mode function now turns the mode
-ON unconditionally.
++++
+** Passing a nil argument to a minor mode defined by define-minor-mode
+now turns the mode ON unconditionally. This is so that you can write, e.g.
+ (add-hook 'text-mode-hook 'foo-minor-mode)
+to enable foo-minor-mode in Text mode buffers, thus removing the need
+for `turn-on-foo-minor-mode' style functions.

** The following obsolete files were removed:
*** New function `special-variable-p' to check whether a variable is
declared as dynamically bound.
++++
** An Emacs Lisp testing tool is now included.
Emacs Lisp developers can use this tool to write automated tests for
their code. See the ERT info manual for details.
** New hook types
++++
*** New function `run-hook-wrapped' for running an abnormal hook by
passing the hook functions as arguments to a "wrapping" function.
+Like `run-hook-with-args-until-success', it stops at the first
+non-nil return value.
+
+++
*** New macro `with-wrapper-hook' for running an abnormal hook as a
set of "wrapping" filters, similar to around advice.
(A version of this macro was actually added in Emacs 23.2 but was not
advertised at the time.)
++++
+** The macros `condition-case-no-debug' and `with-demoted-errors' were
+added in Emacs 23.1, but not advertised.

+++
** The new function `server-eval-at' allows evaluation of Lisp forms on
named Emacs server instances, using TCP sockets.
or RGB triplet, instead of signaling an error if the user provides
invalid input.
++++
** Tool-bars can display separators.
Tool-bar separators are handled like menu separators in menu-bar maps,
i.e. via menu entries of the form `(menu-item "--")'.
*** `image-extension-data' has been renamed to `image-metadata'.
The old name is an obsolete alias to the new one.
-*** Emacs can be compiled with ImageMagick support.
++++
+*** Image mode can view any image type that ImageMagick supports.
+This requires Emacs to be built with ImageMagick support.
Then the function `imagemagick-types' returns a list of image file
extensions that your installation of ImageMagick supports. The
function `imagemagick-register-types' enables ImageMagick support for
these image types, minus those listed in `imagemagick-types-inhibit'.
+Visiting one of these file types will then use Image mode.
-See the Emacs Lisp Reference Manual for more information.
+---
+*** New commands to resize and rotate images in Image mode.
+These require Emacs to be built with ImageMagick support.
+image-transform-fit-to-height, image-transform-fit-to-width,
+image-transform-set-rotation, image-transform-set-scale.
** XML and HTML parsing
If Emacs is compiled with libxml2 support, there are two new functions:
with a nil or omitted VALUE argument, the reporter message is
displayed with a "spinning bar".
++++
** New variable `revert-buffer-in-progress-p' is true while a buffer is
being reverted, even if the buffer has a local `revert-buffer-function'.
-** New variables `delayed-warnings-list' and `delayed-warnings-hook' allow
-deferring warnings until the main command loop is executed.
+---
+** New variables `delayed-warnings-list' and `delayed-warnings-hook'.
+If delayed-warnings-list is non-nil, the command loop calls
+delayed-warnings-hook after post-command-hook. At present, this is
+only used by Emacs on some platforms to display warnings during
+startup, which might otherwise not be noticed. This uses the functions
+display-delayed-warnings and collapse-delayed-warnings.

** rx.el has a new `group-n' construct for explicitly numbered groups.
-** keymaps can inherit from multiple parents.
++++
+** New function `make-composed-keymap' that constructs a new keymap
+from multiple input maps. You can use this to make a keymap that
+inherits from multiple maps, eg:
+ (set-keymap-parent newmap (make-composed-keymap othermap parent))
-** `debug-on-event' lets you debug Emacs when stuck because of inhibit-quit.
++++
+** Set `debug-on-event' to make Emacs enter the debugger e.g. on receipt
+of SIGUSR1. This can be useful when `inhibit-quit' is set.
+++
-** New reader macro ## which stands for the empty symbol.
+** New reader macro ## that stands for the empty symbol.
This means that the empty symbol can now be read back. Also, #: by itself
(when not immediately followed by a possible symbol character) stands for
an empty uninterned symbol.
