-???
+- This is the last stable release of bugzilla which will support mysql version
+  3.22. Future releases will require at least version 3.23.x. The exact minimum
+  version number required has not yet been decided (bug 87958)
+- The use of bugzilla to maintain the shadowdb will be removed before the
+  next stable release. The replacement (using mysql's built in replication) is
+  not supported in 2.16, but we expect that very few sites use this feature.
+  If this would cause a problem for you, please comment in bug 124589
+- ??? Anything else?
