client frame in parent X window ID, via XEmbed. This works like the

** ImageMagick support.
It is now possible to use the ImageMagick library to load many new

** New scrolling commands `scroll-up-line' and `scroll-down-line'
** New property `scroll-command' should be set on a command's symbol to
define it as a scroll command affected by `scroll-preserve-screen-position'.
++++
+** If you customize `scroll-conservatively' to a value greater than 100,
+Emacs will never recenter point in the window when it scrolls due to
+cursor motion commands or commands that move point (e.f., `M-g M-g').
+Previously, you needed to use `most-positive-fixnum' as the value of
+`scroll-conservatively' to achieve the same effect.

+** ``Aggressive'' scrolling now honors the scroll margins.
+If you customize `scroll-up-aggressively' or

+margin.

+`browse-url-mailto-function', which defaults to `browse-url-mail'.
** Directory local variables can apply to file-less buffers, in certain modes
(eg dired, vc-dir, log-edit). For example, adding
will turn on `whitespace-mode' for *vc-diff* buffers. Modes should
call `hack-dir-local-variables-non-file-buffer' to support this.
++++
+** You can prevent directory local variables from applying to subdirectories.
+Add an element (subdirs . nil) to the alist portion of any variables
+settings to indicate said section should not be applied to subdirectories.

** ERC changes
*** New vars `erc-autojoin-timing' and `erc-autojoin-delay'.
** Calendar, Diary, and Appt
+*** New function `diary-hebrew-birthday'.

*** 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.
** SQL Mode enhancements.
-*** Several variables have been marked as safe local variables. The
-variables `sql-product', `sql-user', `sql-server', `sql-database' and

-
*** `sql-dialect' is a synonym for `sql-product'.

+buffer within the current session, the command will display that

+text terminal display, via a char-table entry that is a cons cell.

+** `open-network-stream' can now be used to open an encrypted stream.
+It now accepts an optional `:type' parameter for initiating a TLS
+connection, directly or via STARTTLS. To do STARTTLS, additional
+parameters (`:end-of-command', `:success', `:capabilities-command')
+must also be supplied.
+
+** Code can now use lexical scoping by default instead of dynamic scoping.
+The `lexical-binding' variable lets code use lexical scoping for local
+variables. It is typically set via file-local variables, in which case it
+applies to all the code in that file.
+
+*** `eval' takes a new optional argument `lexical' to choose the new lexical
+binding instead of the old dynamic binding mode.
+
+*** Lexically scoped interpreted functions are represented with a new form
+of function value which looks like (closure ENV ARGS &rest BODY).

+*** New macro `letrec' to define recursive local functions.

+** deferred-action-list and deferred-action-function are obsolete.
** Removed the stack-trace-on-error variable.
Also the debugger can now "continue" from an error, which means it will jump
to the error handler as if the debugger had not been invoked instead of
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'.
