+Deprecated metrics removed in 0.28.0
+------------------------------------
+
+Synapse 0.28.0 removes all of the metrics deprecated by 0.27.0, which are those
+listed under "Old name" below. This has been done to reduce the bandwidth used
+by gathering metrics and the storage requirements for the Prometheus server, as
+well as reducing CPU overhead for both Synapse and Prometheus.
+
+Administrators should update any alerts or monitoring dashboards to use the
+"New name" listed below.
