Features
--------

- Add support for [MSC3231](https://github.com/matrix-org/matrix-doc/pull/3231): Token authenticated registration. Users can be required to submit a token during registration to authenticate themselves. Contributed by Callum Brown. ([\#10142](https://github.com/matrix-org/synapse/issues/10142))
- Add support for [MSC3283](https://github.com/matrix-org/matrix-doc/pull/3283): Expose `enable_set_displayname` in capabilities. ([\#10452](https://github.com/matrix-org/synapse/issues/10452))
- Port the `PresenceRouter` module interface to the new generic interface. ([\#10524](https://github.com/matrix-org/synapse/issues/10524))
- Add pagination to the spaces summary based on updates to [MSC2946](https://github.com/matrix-org/matrix-doc/pull/2946). ([\#10613](https://github.com/matrix-org/synapse/issues/10613), [\#10725](https://github.com/matrix-org/synapse/issues/10725))

Bugfixes
--------

- Validate new `m.room.power_levels` events. Contributed by @aaronraimist. ([\#10232](https://github.com/matrix-org/synapse/issues/10232))
- Display an error on User-Interactive Authentication fallback pages when authentication fails. Contributed by Callum Brown. ([\#10561](https://github.com/matrix-org/synapse/issues/10561))
- Remove pushers when deleting an e-mail address from an account. Pushers for old unlinked emails will also be deleted. ([\#10581](https://github.com/matrix-org/synapse/issues/10581), [\#10734](https://github.com/matrix-org/synapse/issues/10734))
- Reject Client-Server `/keys/query` requests which provide `device_ids` incorrectly. ([\#10593](https://github.com/matrix-org/synapse/issues/10593))
- Rooms with unsupported room versions are no longer returned via `/sync`. ([\#10644](https://github.com/matrix-org/synapse/issues/10644))
- Enforce the maximum length for per-room display names and avatar URLs. ([\#10654](https://github.com/matrix-org/synapse/issues/10654))
- Fix a bug which caused the `synapse_user_logins_total` Prometheus metric not to be correctly initialised on restart. ([\#10677](https://github.com/matrix-org/synapse/issues/10677))
- Improve `ServerNoticeServlet` to avoid duplicate requests and add unit tests. ([\#10679](https://github.com/matrix-org/synapse/issues/10679))
- Fix long-standing issue which caused an error when a thumbnail is requested and there are multiple thumbnails with the same quality rating. ([\#10684](https://github.com/matrix-org/synapse/issues/10684))
- Fix a regression introduced in v1.41.0 which affected the performance of concurrent fetches of large sets of events, in extreme cases causing the process to hang. ([\#10703](https://github.com/matrix-org/synapse/issues/10703))
- Fix a regression introduced in Synapse 1.41 which broke email transmission on Systems using older versions of the Twisted library. ([\#10713](https://github.com/matrix-org/synapse/issues/10713))

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