([\#6787](https://github.com/matrix-org/synapse/issues/6787), [\#6790](https://github.com/matrix-org/synapse/issues/6790), [\#6794](https://github.com/matrix-org/synapse/issues/6794))

Bugfixes
--------

- Warn if postgres database has a non-C locale, as that can cause issues when upgrading locales (e.g. due to upgrading OS). ([\#6734](https://github.com/matrix-org/synapse/issues/6734))

- Fix outbound federation request metrics. ([\#6795](https://github.com/matrix-org/synapse/issues/6795))
- Fix bug where querying a remote user's device keys that weren't cached resulted in only returning a single device. ([\#6796](https://github.com/matrix-org/synapse/issues/6796))
- Fix race in federation sender worker that delayed sending of device updates. ([\#6799](https://github.com/matrix-org/synapse/issues/6799), [\#6800](https://github.com/matrix-org/synapse/issues/6800))
- Fix bug where Synapse didn't invalidate cache of remote users' devices when Synapse left a room. ([\#6801](https://github.com/matrix-org/synapse/issues/6801))
- Fix waking up other workers when remote server is detected to have come back online. ([\#6811](https://github.com/matrix-org/synapse/issues/6811))

Improved Documentation
----------------------

- Clarify documentation related to `user_dir` and `federation_reader` workers. ([\#6775](https://github.com/matrix-org/synapse/issues/6775))

Internal Changes
----------------

- Record room versions in the `rooms` table. ([\#6729](https://github.com/matrix-org/synapse/issues/6729), [\#6788](https://github.com/matrix-org/synapse/issues/6788), [\#6810](https://github.com/matrix-org/synapse/issues/6810))
- Propagate cache invalidates from workers to other workers. ([\#6748](https://github.com/matrix-org/synapse/issues/6748))
- Remove some unnecessary admin handler abstraction methods. ([\#6751](https://github.com/matrix-org/synapse/issues/6751))
- Add some debugging for media storage providers. ([\#6757](https://github.com/matrix-org/synapse/issues/6757))
- Detect unknown remote devices and mark cache as stale. ([\#6776](https://github.com/matrix-org/synapse/issues/6776), [\#6819](https://github.com/matrix-org/synapse/issues/6819))
- Attempt to resync remote users' devices when detected as stale. ([\#6786](https://github.com/matrix-org/synapse/issues/6786))
- Delete current state from the database when server leaves a room. ([\#6792](https://github.com/matrix-org/synapse/issues/6792))
- When a client asks for a remote user's device keys check if the local cache for that user has been marked as potentially stale. ([\#6797](https://github.com/matrix-org/synapse/issues/6797))
- Add background update to clean out left rooms from current state. ([\#6802](https://github.com/matrix-org/synapse/issues/6802), [\#6816](https://github.com/matrix-org/synapse/issues/6816))
- Refactoring work in preparation for changing the event redaction algorithm. ([\#6803](https://github.com/matrix-org/synapse/issues/6803), [\#6805](https://github.com/matrix-org/synapse/issues/6805), [\#6806](https://github.com/matrix-org/synapse/issues/6806), [\#6807](https://github.com/matrix-org/synapse/issues/6807), [\#6820](https://github.com/matrix-org/synapse/issues/6820))
