Merge tag 'v1.58.0rc1' into babolivier/dinsic_1.58

Synapse 1.58.0rc1 (2022-04-26)
==============================

As of this release, the groups/communities feature in Synapse is now disabled by default. See [\#11584](matrix-org/synapse#11584) for details. As mentioned in [the upgrade notes](https://github.com/matrix-org/synapse/blob/develop/docs/upgrade.md#upgrading-to-v1580), this feature will be removed in Synapse 1.61.

Features
--------

- Implement [MSC3383](matrix-org/matrix-spec-proposals#3383) for including the destination in server-to-server authentication headers. Contributed by @Bubu and @jcgruenhage for Famedly. ([\#11398](matrix-org/synapse#11398))
- Docker images and Debian packages from matrix.org now contain a locked set of Python dependencies, greatly improving build reproducibility. ([Board](https://github.com/orgs/matrix-org/projects/54), [\#11537](matrix-org/synapse#11537))
- Enable processing of device list updates asynchronously. ([\#12365](matrix-org/synapse#12365), [\#12465](matrix-org/synapse#12465))
- Implement [MSC2815](matrix-org/matrix-spec-proposals#2815) to allow room moderators to view redacted event content. Contributed by @tulir. ([\#12427](matrix-org/synapse#12427))
- Build Debian packages for Ubuntu 22.04 "Jammy Jellyfish". ([\#12543](matrix-org/synapse#12543))

Bugfixes
--------

- Prevent a sync request from removing a user's busy presence status. ([\#12213](matrix-org/synapse#12213))
- Fix bug with incremental sync missing events when rejoining/backfilling. Contributed by Nick @ Beeper. ([\#12319](matrix-org/synapse#12319))
- Fix a long-standing bug which incorrectly caused `GET /_matrix/client/v3/rooms/{roomId}/event/{eventId}` to return edited events rather than the original. ([\#12476](matrix-org/synapse#12476))
- Fix a bug introduced in Synapse 1.27.0 where the admin API for [deleting forward extremities](https://github.com/matrix-org/synapse/blob/erikj/fix_delete_event_response_count/docs/admin_api/rooms.md#deleting-forward-extremities) would always return a count of 1, no matter how many extremities were deleted. ([\#12496](matrix-org/synapse#12496))
- Fix a long-standing bug where the image thumbnails embedded into email notifications were broken. ([\#12510](matrix-org/synapse#12510))
- Fix a bug in the implementation of [MSC3202](matrix-org/matrix-spec-proposals#3202) where Synapse would use the field name `device_unused_fallback_keys`, rather than `device_unused_fallback_key_types`. ([\#12520](matrix-org/synapse#12520))
- Fix a bug introduced in Synapse 0.99.3 which could cause Synapse to consume large amounts of RAM when back-paginating in a large room. ([\#12522](matrix-org/synapse#12522))

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

- Fix rendering of the documentation site when using the 'print' feature. ([\#12340](matrix-org/synapse#12340))
- Add a manual documenting config file options. ([\#12368](matrix-org/synapse#12368), [\#12527](matrix-org/synapse#12527))
- Update documentation to reflect that both the `run_background_tasks_on` option and the options for moving stream writers off of the main process are no longer experimental. ([\#12451](matrix-org/synapse#12451))
- Update worker documentation and replace old `federation_reader` with `generic_worker`. ([\#12457](matrix-org/synapse#12457))
- Strongly recommend [Poetry](https://python-poetry.org/) for development. ([\#12475](matrix-org/synapse#12475))
- Add some example configurations for workers and update architectural diagram. ([\#12492](matrix-org/synapse#12492))
- Fix a broken link in `README.rst`. ([\#12495](matrix-org/synapse#12495))
- Add HAProxy delegation example with CORS headers to docs. ([\#12501](matrix-org/synapse#12501))
- Remove extraneous comma in User Admin API's device deletion section so that the example JSON is actually valid and works. Contributed by @olmari. ([\#12533](matrix-org/synapse#12533))

Deprecations and Removals
-------------------------

- The groups/communities feature in Synapse is now disabled by default. ([\#12344](matrix-org/synapse#12344))
- Remove unstable identifiers from [MSC3440](matrix-org/matrix-spec-proposals#3440). ([\#12382](matrix-org/synapse#12382))

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

- Preparation for faster-room-join work: start a background process to resynchronise the room state after a room join. ([\#12394](matrix-org/synapse#12394))
- Preparation for faster-room-join work: Implement a tracking mechanism to allow functions to wait for full room state to arrive. ([\#12399](matrix-org/synapse#12399))
- Remove an unstable identifier from [MSC3083](matrix-org/matrix-spec-proposals#3083). ([\#12395](matrix-org/synapse#12395))
- Run CI in the locked [Poetry](https://python-poetry.org/) environment, and remove corresponding `tox` jobs. ([\#12425](matrix-org/synapse#12425), [\#12434](matrix-org/synapse#12434), [\#12438](matrix-org/synapse#12438), [\#12441](matrix-org/synapse#12441), [\#12449](matrix-org/synapse#12449), [\#12478](matrix-org/synapse#12478), [\#12514](matrix-org/synapse#12514), [\#12472](matrix-org/synapse#12472))
- Change Mutual Rooms' `unstable_features` flag to `uk.half-shot.msc2666.mutual_rooms` which matches the current iteration of [MSC2666](matrix-org/matrix-spec-proposals#2666). ([\#12445](matrix-org/synapse#12445))
- Fix typo in the release script help string. ([\#12450](matrix-org/synapse#12450))
- Fix a minor typo in the Debian changelogs generated by the release script. ([\#12497](matrix-org/synapse#12497))
- Reintroduce the list of targets to the linter script, to avoid linting unwanted local-only directories during development. ([\#12455](matrix-org/synapse#12455))
- Limit length of `device_id` to less than 512 characters. ([\#12454](matrix-org/synapse#12454))
- Dockerfile-workers: reduce the amount we install in the image. ([\#12464](matrix-org/synapse#12464))
- Dockerfile-workers: give the master its own log config. ([\#12466](matrix-org/synapse#12466))
- complement-synapse-workers: factor out separate entry point script. ([\#12467](matrix-org/synapse#12467))
- Back out experimental implementation of [MSC2314](matrix-org/matrix-spec-proposals#2314). ([\#12474](matrix-org/synapse#12474))
- Fix grammatical error in federation error response when the room version of a room is unknown. ([\#12483](matrix-org/synapse#12483))
- Remove unnecessary configuration overrides in tests. ([\#12511](matrix-org/synapse#12511))
- Refactor the relations code for clarity. ([\#12519](matrix-org/synapse#12519))
- Add type hints so `docker` and `stubs` directories pass `mypy --disallow-untyped-defs`. ([\#12528](matrix-org/synapse#12528))
- Update `delay_cancellation` to accept any awaitable, rather than just `Deferred`s. ([\#12468](matrix-org/synapse#12468))
- Handle cancellation in `EventsWorkerStore._get_events_from_cache_or_db`. ([\#12529](matrix-org/synapse#12529))

+Synapse 1.58.0rc1 (2022-04-26)
