     - Actually return -1 in the error case for read_bandwidth_usage().
       Harmless bug, since we currently don't care about the return value
       anywhere. Bugfix on 0.2.0.9-alpha.
     - Provide a more useful log message if bug 977 (related to buffer
       freelists) ever reappears, and do not crash right away.
+    - Fix an assertion failure on 64-bit platforms when we allocated
+      memory right up to the end of a memarea, then realigned the memory
+      one step beyond the end. Fixes a possible cause of bug 930.
     - Protect the count of open sockets with a mutex, so we can't
       corrupt it when two threads are closing or opening sockets at once.
-      Fix for bug 939.  Bugfix on 0.2.0.1-alpha.
-    - Don't allow a bridge to publish its router descriptor to a non-bridge
-      directory authority.  Fixes part of bug 932.

 Changes in version 0.2.1.14-rc - 2009-04-12
+  Tor 0.2.1.14-rc marks the first release candidate for the 0.2.1.x
+  series. It begins fixing some major performance problems, and also
+  finally addresses the bug that was causing relays on dynamic IP
+  addresses to fall out of the directory.
+
   o Major features:
     - Clients replace entry guards that were chosen more than a few months
       ago. This change should significantly improve client performance,
