+==============================
+
+Features
+--------
+
+- Support [MSC3266](https://github.com/matrix-org/matrix-doc/pull/3266) room summaries over federation. ([\#11507](https://github.com/matrix-org/synapse/issues/11507))

Contributed by @SimonBrandner. ([\#12168](https://github.com/matrix-org/synapse/issues/12168), [\#12635](https://github.com/matrix-org/synapse/issues/12635), [\#12636](https://github.com/matrix-org/synapse/issues/12636), [\#12670](https://github.com/matrix-org/synapse/issues/12670))

+- Add the `notify_appservices_from_worker` configuration option (superseding `notify_appservices`) to allow a generic worker to be designated as the worker to send traffic to Application Services. ([\#12452](https://github.com/matrix-org/synapse/issues/12452))
+- Add new `enable_registration_token_3pid_bypass` configuration option to allow registrations via token as an alternative to verifying a 3pid. ([\#12526](https://github.com/matrix-org/synapse/issues/12526))

+Bugfixes
+--------
+
+- Fix a bug introduced in Synapse v1.48.0 where latest thread reply provided failed to include the proper bundled aggregations. ([\#12273](https://github.com/matrix-org/synapse/issues/12273))
+- Fix a bug where attempting to send a large amount of read receipts to an application service all at once would result in duplicate content and abnormally high memory usage. Contributed by Brad & Nick @ Beeper. ([\#12544](https://github.com/matrix-org/synapse/issues/12544))
+- Fix a bug introduced in Synapse 1.57 which could cause `Failed to calculate hosts in room` errors to be logged for outbound federation. ([\#12570](https://github.com/matrix-org/synapse/issues/12570))
+- Fix a long standing bug where status codes would almost always get logged as 200!, irrespective of the actual status code, when clients disconnect before a request has finished processing. ([\#12580](https://github.com/matrix-org/synapse/issues/12580))
+- Fix race when persisting an event and deleting a room that could lead to outbound federation breaking. ([\#12594](https://github.com/matrix-org/synapse/issues/12594))

+
+
+Updates to the Docker image
+---------------------------
+
+- Explicitly opt-in to using [BuildKit-specific features](https://github.com/moby/buildkit/blob/master/frontend/dockerfile/docs/syntax.md) in the Dockerfile. This fixes issues with building images in some GitLab CI environments. ([\#12541](https://github.com/matrix-org/synapse/issues/12541))
+- Update the "Build docker images" GitHub Actions workflow to use `docker/metadata-action` to generate docker image tags, instead of a custom shell script. Contributed by henryclw. ([\#12573](https://github.com/matrix-org/synapse/issues/12573))
+
+
+Improved Documentation
+----------------------
+
+- Update SQL statements and replace use of old table `user_stats_historical` in docs for Synapse Admins. ([\#12536](https://github.com/matrix-org/synapse/issues/12536))

+-------------------------
+
