v1.9.0rc1

Synapse 1.9.0rc1 (2020-01-22)

WARNING: As of this release, Synapse no longer supports versions of SQLite before 3.11, and will refuse to start when configured to use an older version. Administrators are recommended to migrate their database to Postgres (see instructions here).

If your Synapse deployment uses workers, note that the reverse-proxy configurations for the synapse.app.media_repository, synapse.app.federation_reader and synapse.app.event_creator have changed, with the addition of a few paths (see the updated configurations here).
