+---------
+
+* Fix for merging multiple changes with "Cherry Pick", "Merge Always" and
+"Merge If Necessary" strategies.
++
+If 2 or more changes were pending submit to the same project and branch,
+it was possible for them to all be marked as status "merged" but only some of
+them to actually land into the branch.
+
+
+Documentation
+-------------
+
+* Minor fixes in the
+link:https://gerrit-documentation.storage.googleapis.com/Documentation/2.8.3/dev-buck.html[
+buck build documentation].
+
+* Clarification of the `commitWithin` setting in the
+link:https://gerrit-documentation.storage.googleapis.com/Documentation/2.8.3/config-gerrit.html#__a_id_index_a_section_index[
