@ -4,6 +4,8 @@ Changes in synapse vx.x.x (x-x-x)
* Add support for registration fallback. This is a page hosted on the server
which allows a user to register for an account, regardless of what client
they are using (e.g. mobile devices).
* Application services can now poll on the CS API ``/events`` for their events,
by providing their application service ``access_token``.
