Synapse 1.9.0 contains a bunch of new admin APIs as well as bug fixes to existing ones. In particular we have a new end point that allows admins to query which rooms their server participates in.

Aside from that it is worth noting that we have officially dropped support for SQLite versions < 3.11. Though more generally we would recommend that all admins migrate to Postgres for anything other than test and evaluation purposes.

Changelog since Synapse 1.8.0

Synapse 1.9.0 (2020-01-23)

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 workers have changed, with the addition of a few paths (see the updated configurations here). Existing configurations will continue to work.
