+Synapse 1.84.1 (2023-05-26)
+===========================
+
+This patch release fixes a major issue with homeservers that do not have an `instance_map` defined but which do use workers.
+If you have already upgraded to Synapse 1.84.0 and your homeserver is working normally, then there is no need to update to this patch release.
