** The implementation of overlays has changed.
Emacs now uses an implementation of overlays that is much more
efficient than the original one, and should speed up all the
operations that involve overlays, especially when there are lots of
them in a buffer. However, no changes in behavior of overlays should
be visible on the Lisp or user level, with the exception of better
performance.

*** New user option to load a locked desktop if locking Emacs is not running.
The option 'desktop-load-locked-desktop' can now be set to the value
'check-pid', which means to allow loading a locked ".emacs.desktop"
file if the Emacs process which locked it is no longer running on the
local machine. This allows avoiding questions about locked desktop
files when the Emacs session which locked it crashes, or was otherwise
interrupted, and didn't exit gracefully. See the "(emacs) Saving
Emacs Sessions" node in the Emacs manual for more details.

*** User option 'minibuffer-eldef-shorten-default' is now obsolete.
