+Synapse 1.58.0rc1 (2022-04-26)
+==============================
+
+Features
+--------
+
+- Implement [MSC3383](https://github.com/matrix-org/matrix-spec-proposals/pull/3383) for including the destination in server-to-server authentication headers. Contributed by @Bubu and @jcgruenhage for Famedly GmbH. ([\#11398](https://github.com/matrix-org/synapse/issues/11398))
+- Use poetry to manage Synapse's dependencies. ([\#12337](https://github.com/matrix-org/synapse/issues/12337))
+- Enable processing of device list updates asynchronously. ([\#12365](https://github.com/matrix-org/synapse/issues/12365), [\#12465](https://github.com/matrix-org/synapse/issues/12465))
+- Implement [MSC2815](https://github.com/matrix-org/matrix-spec-proposals/pull/2815) to allow room moderators to view redacted event content. Contributed by @tulir. ([\#12427](https://github.com/matrix-org/synapse/issues/12427))
+
+
+Bugfixes
+--------
+
+- Prevent a sync request from removing a user's busy presence status. ([\#12213](https://github.com/matrix-org/synapse/issues/12213))
+- Fix bug with incremental sync missing events when rejoining/backfilling. Contributed by Nick @ Beeper. ([\#12319](https://github.com/matrix-org/synapse/issues/12319))
+- Fix a long-standing bug which incorrectly caused `GET /_matrix/client/r3/rooms/{roomId}/event/{eventId}` to return edited events rather than the original. ([\#12476](https://github.com/matrix-org/synapse/issues/12476))
+- Fix bug 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. Broke in v1.27.0. ([\#12496](https://github.com/matrix-org/synapse/issues/12496))
+- Fix a long-standing bug where the image thumbanils embedded into email notifications were broken. ([\#12510](https://github.com/matrix-org/synapse/issues/12510))
+- Fix a bug in the implementation of MSC3202 where Synapse would use the field name `device_unused_fallback_keys`, rather than `device_unused_fallback_key_types`. ([\#12520](https://github.com/matrix-org/synapse/issues/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](https://github.com/matrix-org/synapse/issues/12522))
+
+
+Improved Documentation
+----------------------
+
+- Fix rendering of the documentation site when using the 'print' feature. ([\#12340](https://github.com/matrix-org/synapse/issues/12340))
+- Add a manual documenting config file options. ([\#12368](https://github.com/matrix-org/synapse/issues/12368))
+- 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](https://github.com/matrix-org/synapse/issues/12451))
+- Update worker documentation and replace old `federation_reader` with `generic_worker`. ([\#12457](https://github.com/matrix-org/synapse/issues/12457))
+- Strongly recommend `poetry` for development. ([\#12475](https://github.com/matrix-org/synapse/issues/12475))
+- Add some example configurations for workers and update architectural diagram. ([\#12492](https://github.com/matrix-org/synapse/issues/12492))
+- Fix a broken link in `README.rst`. ([\#12495](https://github.com/matrix-org/synapse/issues/12495))
+- Add HAProxy delegation example with CORS headers to docs. ([\#12501](https://github.com/matrix-org/synapse/issues/12501))
+- Add an index to the configuration manual. ([\#12527](https://github.com/matrix-org/synapse/issues/12527))
+- 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](https://github.com/matrix-org/synapse/issues/12533))
+
+

+- Remove unstable identifiers from [MSC3440](https://github.com/matrix-org/matrix-doc/pull/3440). ([\#12382](https://github.com/matrix-org/synapse/issues/12382))
+
+
+Internal Changes
