+Synapse 1.60.0rc1 (2022-05-24)
+==============================
+
+This release of Synapse adds a unique index to the `state_group_edges` table, in
+order to prevent accidentally introducing duplicate information (for example,
+because a database backup was restored multiple times). If your Synapse database
+already has duplicate rows in this table, this could fail with an error and
+require manual remediation.
+
+Additionally, the signature of the `check_event_for_spam` module callback has changed.
+The previous signature has been deprecated and remains working for now. Module authors
+should update their modules to use the new signature where possible.
+
+See [the upgrade notes](https://github.com/matrix-org/synapse/blob/develop/docs/upgrade.md#upgrading-to-v1600)
+for more details.
+
+Features
+--------
+
+- Measure the time taken in spam-checking callbacks and expose those measurements as metrics. ([\#12513](https://github.com/matrix-org/synapse/issues/12513))
+- Add a `default_power_level_content_override` config option to set default room power levels per room preset. ([\#12618](https://github.com/matrix-org/synapse/issues/12618))
+- Add support for [MSC3787: Allowing knocks to restricted rooms](https://github.com/matrix-org/matrix-spec-proposals/pull/3787). ([\#12623](https://github.com/matrix-org/synapse/issues/12623))
+- Send `USER_IP` commands on a different Redis channel, in order to reduce traffic to workers that do not process these commands. ([\#12672](https://github.com/matrix-org/synapse/issues/12672), [\#12809](https://github.com/matrix-org/synapse/issues/12809))
+- Synapse will now reload [cache config](https://matrix-org.github.io/synapse/latest/usage/configuration/config_documentation.html#caching) when it receives a [SIGHUP](https://en.wikipedia.org/wiki/SIGHUP) signal. ([\#12673](https://github.com/matrix-org/synapse/issues/12673))
+- Add a config options to allow for auto-tuning of caches. ([\#12701](https://github.com/matrix-org/synapse/issues/12701))
+- Update [MSC2716](https://github.com/matrix-org/matrix-spec-proposals/pull/2716) implementation to process marker events from the current state to avoid markers being lost in timeline gaps for federated servers which would cause the imported history to be undiscovered. ([\#12718](https://github.com/matrix-org/synapse/issues/12718))
+- Add a `drop_federated_event` callback to `SpamChecker` to disregard inbound federated events before they take up much processing power, in an emergency. ([\#12744](https://github.com/matrix-org/synapse/issues/12744))
+- Implement [MSC3818: Copy room type on upgrade](https://github.com/matrix-org/matrix-spec-proposals/pull/3818). ([\#12786](https://github.com/matrix-org/synapse/issues/12786), [\#12792](https://github.com/matrix-org/synapse/issues/12792))
+- Update to the `check_event_for_spam` module callback. Deprecate the current callback signature, replace it with a new signature that is both less ambiguous (replacing booleans with explicit allow/block) and more powerful (ability to return explicit error codes). ([\#12808](https://github.com/matrix-org/synapse/issues/12808))
+
+
+Bugfixes
+--------
+
+- Fix a bug introduced in Synapse 1.7.0 that would prevent events from being sent to clients if there's a retention policy in the room when the support for retention policies is disabled. ([\#12611](https://github.com/matrix-org/synapse/issues/12611))
+- Fix a bug introduced in Synapse 1.57.0 where `/messages` would throw a 500 error when querying for a non-existent room. ([\#12683](https://github.com/matrix-org/synapse/issues/12683))
+- Add a unique index to `state_group_edges` to prevent duplicates being accidentally introduced and the consequential impact to performance. ([\#12687](https://github.com/matrix-org/synapse/issues/12687))
+- Fix a long-standing bug where an empty room would be created when a user with an insufficient power level tried to upgrade a room. ([\#12696](https://github.com/matrix-org/synapse/issues/12696))
+- Fix a bug introduced in Synapse 1.30.0 where empty rooms could be automatically created if a monthly active users limit is set. ([\#12713](https://github.com/matrix-org/synapse/issues/12713))
+- Fix push to dismiss notifications when read on another client. Contributed by @SpiritCroc @ Beeper. ([\#12721](https://github.com/matrix-org/synapse/issues/12721))
+- Fix poor database performance when reading the cache invalidation stream for large servers with lots of workers. ([\#12747](https://github.com/matrix-org/synapse/issues/12747))
+- Delete events from the `federation_inbound_events_staging` table when a room is purged through the admin API. ([\#12770](https://github.com/matrix-org/synapse/issues/12770))
+- Give a meaningful error message when a client tries to create a room with an invalid alias localpart. ([\#12779](https://github.com/matrix-org/synapse/issues/12779))
+- Fix a bug introduced in 1.43.0 where a file (`providers.json`) was never closed. Contributed by @arkamar. ([\#12794](https://github.com/matrix-org/synapse/issues/12794))
+- Fix a long-standing bug where finished log contexts would be re-started when failing to contact remote homeservers. ([\#12803](https://github.com/matrix-org/synapse/issues/12803))
+- Fix a bug, introduced in Synapse 1.21.0, that led to media thumbnails being unusable before the index has been added in the background. ([\#12823](https://github.com/matrix-org/synapse/issues/12823))
+
+
+Updates to the Docker image
+---------------------------
+
+- Fix the docker file after a dependency update. ([\#12853](https://github.com/matrix-org/synapse/issues/12853))
+
+

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

+- Fix typo in `run_background_tasks_on` option name in configuration manual documentation. ([\#12749](https://github.com/matrix-org/synapse/issues/12749))
+- Add information regarding the `rc_invites` ratelimiting option to the configuration docs. ([\#12759](https://github.com/matrix-org/synapse/issues/12759))
+- Add documentation for cancellation of request processing. ([\#12761](https://github.com/matrix-org/synapse/issues/12761))

+- Require a body in POST requests to `/rooms/{roomId}/receipt/{receiptType}/{eventId}`, as required by the [Matrix specification](https://spec.matrix.org/v1.2/client-server-api/#post_matrixclientv3roomsroomidreceiptreceipttypeeventid). This breaks compatibility with Element Android 1.2.0 and earlier: users of those clients will be unable to send read receipts. ([\#12709](https://github.com/matrix-org/synapse/issues/12709))
+
+
