+Performance
+-----------
+
+Automatic tag query optimization
+
+ "notmuch tag" now automatically optimizes the user's query to
+ exclude messages whose tags won't change. In the past, we've
+ suggested that people do this by hand; this is no longer necessary.
+
+Don't sort messages when creating a dump file
+
+ This speeds up tag dumps considerably, without any loss of
+ information.
+
+Memory Management
+-----------------
+
+Reduction of memory leaks
+
+ Two memory leaks when searching and showing messages were identified
+ and fixed in this release.
+
+Emacs Interface
+---------------
+
+Bug fixes
+
+ notmuch-show-advance (bound to the spacebar in notmuch-show-mode) had
+ a bug that caused it to always jump to the next message, even if it
+ should have scrolled down to show more of the current message instead.
+ This is now fixed.
