** Xwidgets: a new feature for embedding native widgets inside Emacs buffers.
-If you have gtk3 and webkitgtk3 installed, you can access the
-embedded webkit browser with `M-x xwidget-webkit-browse-url'. This
-opens a new buffer with the embedded browser. The buffer will

-which supports the webkit widget.

+xwidget-webkit-browse-url'. This opens a new buffer with the embedded

*** New functions for xwidget-webkit mode `xwidget-webkit-insert-string',
`xwidget-webkit-adjust-size-dispatch', `xwidget-webkit-back',
`xwidget-webkit-browse-url', `xwidget-webkit-reload',
at configure time.

-** Emacs now supports "bracketed paste mode" when running on a terminal
-that supports it. This facility allows Emacs to understand pasted
-chunks of text as strings to be inserted, instead of interpreting each
-character in the pasted text as actual user input. This results in a
-paste experience similar to that under a window system, and significant
-performance improvements when pasting large amounts of text.
+** Emacs now uses "bracketed paste mode" on text terminals that support it.
+Bracketed paste mode causes text terminals to wrap pasted text in special
+escape sequences that allow Emacs to tell the difference between text
+you type and text you paste from other applications. Emacs then
+avoids interpreting each character in the pasted text as it does with
+keyboard input, which results in a paste experience similar to that
+under a window system, and significant performance improvements when
+pasting large amounts of text.
+
+Bracketed paste mode is disabled by default, so Emacs automatically
+enables it at startup if the terminal supports it.
+++
** Emacs now supports the latest version of the UBA.
It raises an error if a bookmark of that name already exists,
unlike `bookmark-set' which silently updates an existing bookmark.
+** Gnus
+
++++
+*** New user options `mm-html-inhibit-images' and `mm-html-blocked-images'
+now control how mm-* functions fetch and display images in an HTML
+message. Gnus still uses `gnus-inhibit-images' and `gnus-blocked-images'
+for that purpose, i.e., binds mm-html- variables with those gnus-
+variables, but other packages do not have to bind gnus- variables now.
+
+---
+*** `mm-inline-text-html-with-images' has been removed.
+Use `mm-html-inhibit-images' instead. Note that the value is opposite
+in meaning.

*** Reconnection is now asynchronous.

+being made case-sensitive in Emacs 24.2.

+**** `<' and `>' for navigating previous and next tracks in playlist

+**** `g' bound to new command `mpc-seek-current' will navigate current

+**** New commands `mpc-toggle-{consume,repeat,single,shuffle}' for
+ toggling playback modes.

specifies the default mode for I-search.
+++
*** text/html messages that contain inline image parts will be
transformed into multipart/related messages before sending.
+---
+*** The `message-valid-fqdn-regexp' variable has been removed, since
+there are now top-level domains added all the time. Message will no
+longer warn about sending emails to top-level domains it hasn't heard
+about.
+
+*** `message-beginning-of-line' (bound to C-a) understands folded headers.
+In `visual-line-mode' it will look for the true beginning of a header
+while in non-`visual-line-mode' it will move the point to the indented
+header’s value.

** In Show Paren Mode, a parenthesis can be highlighted when point
stands inside it, and certain parens can be highlighted when point is
respectively, `show-paren-when-point-inside-paren' or
`show-paren-when-point-in-periphery'.

+** If gpg2 exists on the system, it is now used as the default value
+of `epg-gpg-program' (instead of gpg).
+
+** Images
+
++++
+*** Images are automatically scaled before displaying based on the
+`image-scaling-factor' variable (if Emacs supports scaling the images
+in question).
+
+*** Images inserted with `insert-image' and related functions get a
+keymap put into the text properties (or overlays) that span the
+image. This keymap binds keystrokes for manipulating size and
+rotation, as well as saving the image to a file.

*** 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 effect is that, on systems that use ls-lisp for Dired, the default
+sort order of the files in Dired is now different from what it was in
+previous versions of Emacs. In particular, the file names are sorted
+disregarding punctuation, accents, and diacritics, and letter case is
+ignored. For example, files whose name begin with a period will no
+longer appear near the beginning of the directory listing. If you
+want the old, locale-independent sorting, customize the new option
+`ls-lisp-use-string-collate' to the nil value.

*** The MS-Windows specific variable `w32-collate-ignore-punctuation',

+** The new function `bidi-find-overridden-directionality' allows you 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
+** The new function `buffer-substring-with-bidi-context' allows you 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
integers.
