Merge tag 'v1.54.0rc1' into develop

Synapse 1.54.0rc1 (2022-03-02)
==============================

Please note that this will be the last release of Synapse that is compatible with Mjolnir 1.3.1 and earlier.
Administrators of servers which have the Mjolnir module installed are advised to upgrade Mjolnir to version 1.3.2 or later.

Features
--------

- Add support for [MSC3202](https://github.com/matrix-org/matrix-doc/pull/3202): sending one-time key counts and fallback key usage states to Application Services. ([\#11617](https://github.com/matrix-org/synapse/issues/11617))
- Improve the generated URL previews for some web pages. 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 and 1.2 support on `/_matrix/client/versions`. ([\#12020](https://github.com/matrix-org/synapse/issues/12020), ([\#12022](https://github.com/matrix-org/synapse/issues/12022))
- 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))
- 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 1.48.0 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 the `get_rooms_for_user` cache was not correctly invalidated for remote users when the server left a room. ([\#11999](https://github.com/matrix-org/synapse/issues/11999))
- Fix a 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 into 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 in version 1.38.0. ([\#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 1.51.0 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))
- 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. This reduces server load and load on the receiving device. ([\#11835](https://github.com/matrix-org/synapse/issues/11835))

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))

Internal Changes

- Remove unnecessary condition on knock -> leave auth rule check. ([\#11900](https://github.com/matrix-org/synapse/issues/11900))

- 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))
