Upgrading to v1.20.0
====================
Shared rooms endpoint (MSC2666)
-------------------------------
This release contains a new unstable endpoint `/_matrix/client/unstable/uk.half-shot.msc2666/user/shared_rooms/.*`
for fetching rooms one user has in common with another. This feature requires the
`update_user_directory` config flag to be `True`. If you are you are using a `synapse.app.user_dir`
worker, requests to this endpoint must be handled by that worker.
See `docs/workers.md <docs/workers.md>`_ for more details.
Upgrading Synapse
