+# Upgrading to v1.76.0
+
+## Changes to the account data replication streams
+
+Synapse has changed the format of the account data replication streams (between
+workers). This is a forwards- and backwards-incompatible change: v1.75 workers
+cannot process account data replicated by v1.76 workers, and vice versa.
+
+Once all workers are upgraded to v1.76 (or downgraded to v1.75), account data
+replication will resume as normal.
