+Generally Synapse database schemas are compatible across multiple versions, once
+a version of Synapse is deployed you may not be able to rollback automatically.
+The following table gives the version ranges and the earliest version they can
+be rolled back to. E.g. Synapse versions v1.58.0 through v1.61.1 can be rolled
+back safely to v1.57.0, but starting with v1.62.0 it is only safe to rollback to
+v1.61.0.
