+            Servers MAY implement this parameter ahead of declaring support for

+            clients MAY set this parameter to `true` regardless of the
+            [`/versions`](/client-server-api/#get_matrixclientversions) response.

+            parameter from the presence of `state_after` in the response. If

+            specified the parameter and update their local state with events
+            in `state` and `timeline`.

            By default, this is `false`.
