*** If emacsclient shuts down as a result of Emacs signalling an
error, its exit status is 1.

See the node "Bidirectional Editing" in the Emacs Manual for some
initial documentation.
`display' text properties, do not yet work correctly when
bidirectional text is reordered for display.
++++
+*** Enhanced support for characters that have no glyphs in available fonts.
+If a character has no glyphs in any of the available fonts, Emacs by
+default will display it either as a hexadecimal code in a box or as a
+thin 1-pixel space. In addition to these two methods, Emacs can
+display these characters as empty box, as an acronym, or not display
+them at all. To change how these characters are displayed, customize
+the variable `glyphless-char-display-control'.
+
+On character terminals these methods are used for characters that
+cannot be encoded by the `terminal-coding-system'.
+
+*** There are two new input methods for Persian/Farsi: farsi and farsi-translit.
+
** GTK scroll-bars are now placed on the right by default.
Use `set-scroll-bar-mode' to change this.

ns-auto-hide-menu-bar.

the remote file-name cache is used for read access.
++++
+** The use of a "mode: minor" specification in a file local variables section
+to enable a minor-mode is deprecated. Instead, use "eval: (minor-mode)".
+
** The standalone programs lib-src/digest-doc and sorted-doc have been
replaced with Lisp commands `doc-file-to-man' and `doc-file-to-info'.
+---
+** The standalone program `fakemail' has been removed.
+If you need it, feedmail.el ought to provide a superset of the functionality.

** The variable `focus-follows-mouse' now always defaults to nil.
+** Function `sha1' is now implemented in C for speed.

+controlling the degree of parallelism.
+
** Directory local variables can apply to file-less buffers, in certain modes
(eg dired, vc-dir, log-edit). For example, adding
"(diff-mode . ((mode . whitespace)))" to your .dir-locals.el file,
** Calendar, Diary, and Appt

+---
+*** Elements of `calendar-day-abbrev-array' and `calendar-month-abbrev-array'
+may no longer be nil, but must all be strings.

*** The obsolete (since Emacs 22.1) method of enabling the appt package
by adding appt-make-list to diary-hook has been removed. Use appt-activate.
*** The following access methods are discontinued: "ssh1_old",
"ssh2_old", "scp1_old", "scp2_old", "imap", "imaps" and "fish".

* New Modes and Packages in Emacs 24.1
+** Occur Edit mode applies edits made in *Occur* buffers to the
+original buffers. It is bound to C-x C-q in Occur mode.
+
** New global minor modes electric-pair-mode, electric-indent-mode,
and electric-layout-mode.

* Lisp changes in Emacs 24.1
+** Completion
+*** New variable completion-extra-properties used to specify extra properties
+of the current completion:
+- :annotate-function, same as the old completion-annotate-function.
+- :exit-function, function to call after completion took place.
+
+*** Functions on completion-at-point-functions can return any of the properties
+valid for completion-extra-properties.
+
+*** completion-annotate-function is obsolete.
+
+*** New `metadata' method for completion tables. The metadata thus returned
+can specify various details of the data returned by `all-completions':
+- `category' is the kind of objects returned (e.g., `buffer', `file', ...),
+ used to select a style in completion-category-overrides.
+- `annotation-function' to add annotations in *Completions*.
+- `display-sort-function' to specify how to sort entries in *Completions*.
+- `cycle-sort-function' to specify how to sort entries when cycling.
+
** `glyphless-char-display' can now distinguish between graphical and
text terminal display, via a char-table entry that is a cons cell.
** New low-level function run-hook-wrapped.
+** `server-eval-at' is provided to allow evaluating forms on different
+Emacs server instances.
+
+** `call-process' allows a `(:file "file")' spec to redirect STDOUT to
+a file.
+
** byte-compile-disable-print-circle is obsolete.
** deferred-action-list and deferred-action-function are obsolete.
** Removed the stack-trace-on-error variable.
** buffer-substring-filters is obsoleted by filter-buffer-substring-functions.
-** New completion style `substring'.
-
** `facemenu-read-color' is now an alias for `read-color'.
The command `read-color' now requires a match for a color name or RGB
triplet, instead of signalling an error if the user provides a invalid
FIXME: These should be front-ended by xml.el.
-** FIXME GnuTLS
+** GnuTLS
+
+*** Emacs can be compiled with libgnutls support
+This is the default. You will then be able to use the functionality
+in gnutls.el, namely the `open-gnutls-stream' and `gnutls-negotiate'
+functions. It's easiest to use these functions through
+`open-network-stream' because it can upgrade connections through
+STARTTLS opportunistically or use plain SSL, depending on your needs.
+
+Only versions 2.8.x and higher or GnuTLS have been tested.
+
+*** gnutls-log-level
+Set `gnutls-log-level' higher than 0 to get debug output. 1 is for
+important messages, 2 is for debug data, and higher numbers are as per
+the GnuTLS logging conventions. The output is in *Messages*.
** Isearch
** New variables `delayed-warnings-list' and `delayed-warnings-hook' allow
deferring warnings until the main command loop is executed.
++++
+** `set-auto-mode' now respects mode: local variables at the end of files,
+as well as those in the -*- line.
+

included in binary distribution.
+** New configure.bat option --without-gnutls to disable automatic
+GnuTLS detection.
+
+** New configure.bat option --lib for general library linkage, works
+with the USER_LIBS build variable.
+
** New make target `dist' to create binary distribution for MS Windows.
