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.

([\#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.
