+## Legacy Prometheus metric names are now disabled by default
+
+Synapse v1.71.0 disables legacy Prometheus metric names by default.
+For administrators that still rely on them and have not yet had chance to update their
+uses of the metrics, it's still possible to specify `enable_legacy_metrics: true` in
+the configuration to re-enable them temporarily.
+
+Synapse v1.73.0 will **remove legacy metric names altogether** and at that point,
+it will no longer be possible to re-enable them.
+
+If you do not use metrics or you have already updated your Grafana dashboard(s),
+Prometheus console(s) and alerting rule(s), there is no action needed.
+
