+## Removal of `worker_replication_*` settings
+
+As mentioned previously in [Upgrading to v1.84.0](#upgrading-to-v1840), the following deprecated settings
+are being removed in this release of Synapse:
+
+* [`worker_replication_host`](https://matrix-org.github.io/synapse/v1.86/usage/configuration/config_documentation.html#worker_replication_host)
+* [`worker_replication_http_port`](https://matrix-org.github.io/synapse/v1.86/usage/configuration/config_documentation.html#worker_replication_http_port)
+* [`worker_replication_http_tls`](https://matrix-org.github.io/synapse/v1.86/usage/configuration/config_documentation.html#worker_replication_http_tls)
+
+Please ensure that you have migrated to using `main` on your shared configuration's `instance_map`
+(or create one if necessary). This is required if you have ***any*** workers at all;
+administrators of single-process (monolith) installations don't need to do anything.
+
+For an illustrative example, please see [Upgrading to v1.84.0](#upgrading-to-v1840) below.
