+Synapse 1.54.0rc1 (2022-03-02)
+==============================
+
+Features
+--------
+
+- Add support for MSC3202: sending one-time key counts and fallback key usage states to Application Services. ([\#11617](https://github.com/matrix-org/synapse/issues/11617))
+- Make a `POST` to `/rooms/<room_id>/receipt/m.read/<event_id>` only trigger a push notification if the count of unread messages is different to the one in the last successfully sent push. ([\#11835](https://github.com/matrix-org/synapse/issues/11835))
+- Fetch images when previewing Twitter URLs. Contributed by @AndrewRyanChama. ([\#11985](https://github.com/matrix-org/synapse/issues/11985))
+- Track cache invalidations in Prometheus metrics, as already happens for cache eviction based on size or time. ([\#12000](https://github.com/matrix-org/synapse/issues/12000))
+- Implement experimental support for [MSC3720](https://github.com/matrix-org/matrix-doc/pull/3720) (account status endpoints). ([\#12001](https://github.com/matrix-org/synapse/issues/12001), [\#12067](https://github.com/matrix-org/synapse/issues/12067))
+- Enable modules to set a custom display name when registering a user. ([\#12009](https://github.com/matrix-org/synapse/issues/12009))
+- Advertise Matrix 1.1 support on `/_matrix/client/versions`. ([\#12020](https://github.com/matrix-org/synapse/issues/12020))
+- Support only the stable identifier for [MSC3069](https://github.com/matrix-org/matrix-doc/pull/3069)'s `is_guest` on `/_matrix/client/v3/account/whoami`. ([\#12021](https://github.com/matrix-org/synapse/issues/12021))
+- Advertise Matrix 1.2 support on `/_matrix/client/versions`. ([\#12022](https://github.com/matrix-org/synapse/issues/12022))
+- Use room version 9 as the default room version (per [MSC3589](https://github.com/matrix-org/matrix-doc/pull/3589)). ([\#12058](https://github.com/matrix-org/synapse/issues/12058))
+- Add module callbacks to react to user deactivation status changes (i.e. deactivations and reactivations) and profile updates. ([\#12062](https://github.com/matrix-org/synapse/issues/12062))
+
+
+Bugfixes
+--------
+
+- Fix a bug introduced in Synapse v1.48.0 where an edit of the latest event in a thread would not be properly applied to the thread summary. ([\#11992](https://github.com/matrix-org/synapse/issues/11992))
+- Fix long standing bug where `get_rooms_for_user` was not correctly invalidated for remote users when the server left a room. ([\#11999](https://github.com/matrix-org/synapse/issues/11999))
+- Fix 500 error with Postgres when looking backwards with the [MSC3030](https://github.com/matrix-org/matrix-doc/pull/3030) `/timestamp_to_event?dir=b` endpoint. ([\#12024](https://github.com/matrix-org/synapse/issues/12024))
+- Properly fix a long-standing bug where wrong data could be inserted in the `event_search` table when using sqlite. This could block running `synapse_port_db` with an "argument of type 'int' is not iterable" error. This bug was partially fixed by a change in Synapse 1.44.0. ([\#12037](https://github.com/matrix-org/synapse/issues/12037))
+- Fix slow performance of `/logout` in some cases where refresh tokens are in use. The slowness existed since the initial implementation of refresh tokens. ([\#12056](https://github.com/matrix-org/synapse/issues/12056))
+- Fix a long-standing bug where Synapse would make additional failing requests over federation for missing data. ([\#12077](https://github.com/matrix-org/synapse/issues/12077))
+- Fix occasional 'Unhandled error in Deferred' error message. ([\#12089](https://github.com/matrix-org/synapse/issues/12089))
+- Fix a bug introduced in Synapse 1.51.0rc1 where incoming federation transactions containing at least one EDU would be dropped if debug logging was enabled for `synapse.8631_debug`. ([\#12098](https://github.com/matrix-org/synapse/issues/12098))
+- Fix a long-standing bug which could cause push notifications to malfunction if `use_frozen_dicts` was set in the configuration. ([\#12100](https://github.com/matrix-org/synapse/issues/12100))
+- Fix an extremely rare, long-standing bug in `ReadWriteLock` that would cause an error when a newly unblocked writer completes instantly. ([\#12105](https://github.com/matrix-org/synapse/issues/12105))
+
+
+Updates to the Docker image
+---------------------------
+
+- The docker image no longer automatically creates a temporary volume at `/data`. This is not expected to affect normal usage. ([\#11997](https://github.com/matrix-org/synapse/issues/11997))
+- Use Python 3.9 in Docker images by default. ([\#12112](https://github.com/matrix-org/synapse/issues/12112))
+
+
+Improved Documentation
+----------------------
+
+- Document support for the `to_device`, `account_data`, `receipts`, and `presence` stream writers for workers. ([\#11599](https://github.com/matrix-org/synapse/issues/11599))
+- Explain the meaning of spam checker callbacks' return values. ([\#12003](https://github.com/matrix-org/synapse/issues/12003))
+- Clarify information about external Identity Provider IDs. ([\#12004](https://github.com/matrix-org/synapse/issues/12004))
+
+
+Deprecations and Removals
+-------------------------
+
+- Deprecate using `synctl` with the config option `synctl_cache_factor` and print a warning if a user still uses this option. ([\#11865](https://github.com/matrix-org/synapse/issues/11865))
+- Remove support for the legacy structured logging configuration (please see the the [upgrade notes](https://matrix-org.github.io/synapse/develop/upgrade#legacy-structured-logging-configuration-removal) if you are using `structured: true` in the Synapse configuration). ([\#12008](https://github.com/matrix-org/synapse/issues/12008))
+- Drop support for [MSC3283](https://github.com/matrix-org/matrix-doc/pull/3283) unstable flags now that the stable flags are supported. ([\#12018](https://github.com/matrix-org/synapse/issues/12018))
+- Remove the unstable `/spaces` endpoint from [MSC2946](https://github.com/matrix-org/matrix-doc/pull/2946). ([\#12073](https://github.com/matrix-org/synapse/issues/12073))
+
+

+- Limit concurrent joins from applications services. ([\#11996](https://github.com/matrix-org/synapse/issues/11996))
+- Preparation for faster-room-join work: when parsing the `send_join` response, get the `m.room.create` event from `state`, not `auth_chain`. ([\#12005](https://github.com/matrix-org/synapse/issues/12005), [\#12039](https://github.com/matrix-org/synapse/issues/12039))

+- Upgrade mypy to version 0.931. ([\#12030](https://github.com/matrix-org/synapse/issues/12030))
+- Remove legacy `HomeServer.get_datastore()`. ([\#12031](https://github.com/matrix-org/synapse/issues/12031), [\#12070](https://github.com/matrix-org/synapse/issues/12070))
+- Minor typing fixes. ([\#12034](https://github.com/matrix-org/synapse/issues/12034), [\#12069](https://github.com/matrix-org/synapse/issues/12069))
