+Cycle highlights marketing deadline
+-----------------------------------
+
+Cycle highlights need to be added to the release deliverables by feature freeze to
+be included in any marketing release messaging. Highlights may be added after
+this point, but they will likely only be useful for historical purposes.
+
+See the `project team guide <https://docs.openstack.org/project-team-guide/release-management.html#cycle-highlights>`_
