+
+Bug Fixes
+---------
+* issue 1139 Fix change state in patch set approval if reviewer is added to
+closed change
++
+For the dummy patch set approval that is created when a reviewer is
+added the cached change state is always open, which is incorrect if a
+reviewer is added to a closed change. As a result the closed change will
+appear in the reviewers dashboard in the 'Review Requests' section and will
+stay there forever.  Ensure the correct change state is cached in the dummy
+patch set approval when it is created.
+
+* issue 1171 Fix ownerin and reviewerin searches
++
+Update the ownerin and reviewerin searches to use AccountGroup.UUID as
+required by commit e662fb3d4d7d0ad05791b8d2143ac5ce58117335.
+
+* issue 871 Display hash of the cherry-pick merge in comment
++
+After merging a change via cherry-pick, we add the commit's
+hash to the comment. This was accidentally removed in
+commit 14246de3c0f81c06bba8d4530e6bf00e918c11b0
+
+
+Documentation
