+** 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.

 ** The docstrings of preloaded files are not in "etc/DOC" any more.
 Instead, they're fetched as needed from the corresponding ".elc" file,
 as was already the case for all the non-preloaded files.
