*** New emacsclient argument --parent-id ID.
** New basic faces `error', `warning', `success' are available to
highlight strings that indicate failure, caution or successful operation.

** Lucid menus and dialogs can display antialiased fonts if Emacs is built
with Xft. To change font, use the X resource font, for example:

display actions, taking precedence over `display-buffer-base-action'.

-resizing or creating a window more reliably to the window from which
-such space was obtained.

+The new option `window-combination-limit' allows to return the space
+obtained for resizing or creating a window more reliably to the window

prompts for a number to count from and for a format string.

-** The default value of redisplay-dont-change is now t
+** The default value of redisplay-dont-pause is now t
This makes Emacs feel more responsive to editing commands that arrive
at high rate, e.g. if you lean on some key, because stopping redisplay
in the middle (when this variable is nil) forces more expensive
updates later on, and Emacs appears to be unable to keep up.
++++
+** The behavior of <TAB> for active regions in Text mode has changed.
+In Text and related modes, typing <TAB> (`indent-for-tab-command')
+when the region is active causes Emacs to indent all the lines in the
+region, aligning them with the line previous to the first line in the
+region (or with the left margin if there is no previous line).
