Synapse 0.33.3 Released

All the threes, Synapse 0.33.3!

This release brings together a lot of bugfixes, and also some preparation for support for Lazy Loading and Room Versioning.

We also have, as a great contribution from @vojeroen, SNI extension support! With v0.33.3, Synapse now supports sending SNI over federation for vhosted servers, which resolves this long-standing request.

As always, you can get the new update from https://github.com/matrix-org/synapse/releases/tag/v0.33.3 or any of the sources mentioned at https://github.com/matrix-org/synapse.
