 Improve performance of `ownerin:` predicate for internal groups.
 
+* [Issue 9195](https://bugs.chromium.org/p/gerrit/issues/detail?id=9195):
+Strip comment lines out of commit message when creating change.
+
+  When a change was created from the UI (or via the 'Create Change' REST
+  API), and the commit message consisted of only a subject beginning with
+  a hash character (`#`), the change was created with a zero Change-Id.
+
+  This was beause lines beginning with `#` are considered to be comments,
+  and are stripped from the commit message by JGit before computing the
+  Change-Id for the commit.
+
+  Before attempting to create the change, Gerrit now strips out any comment
+  lines from the commit message and returns an error if this results in
+  the commit message being empty.
+
+* Add reporting of work queue related metrics.
+
+  Metrics are reported for core work queues. For work queues created by plugins,
+  metrics are not reported.
+
 * Fix double creation of SSH command execution queues.
 
 * Don't trim leading whitespace from about.md content.
