Synapse 1.84.0 (2023-05-23)

The worker_replication_* configuration settings have been deprecated in favour of configuring the main process consistently with other instances in the instance_map. The deprecated settings will be removed in Synapse v1.88.0, but changing your configuration in advance is recommended. See the upgrade notes for more information.
