Synapse 1.34.0rc1 (2021-05-12) ============================== This release deprecates the `room_invite_state_types` configuration setting. See the [upgrade notes](https://github.com/matrix-org/synapse/blob/release-v1.34.0/UPGRADE.rst#upgrading-to-v1340) for instructions on updating your configuration file to use the new `room_prejoin_state` setting. This release also deprecates the `POST /_synapse/admin/v1/rooms/<room_id>/delete` admin API route. Server administrators are encouraged to update their scripts to use the new `DELETE /_synapse/admin/v1/rooms/<room_id>` route instead. Features -------- - Add experimental option to track memory usage of the caches. ([\#9881](https://github.com/matrix-org/synapse/issues/9881)) - Add support for `DELETE /_synapse/admin/v1/rooms/<room_id>`. ([\#9889](https://github.com/matrix-org/synapse/issues/9889)) - Add limits to how often Synapse will GC, ensuring that large servers do not end up GC thrashing if `gc_thresholds` has not been correctly set. ([\#9902](https://github.com/matrix-org/synapse/issues/9902)) - Improve performance of sending events for worker-based deployments using Redis. ([\#9905](https://github.com/matrix-org/synapse/issues/9905), [\#9950](https://github.com/matrix-org/synapse/issues/9950), [\#9951](https://github.com/matrix-org/synapse/issues/9951)) - Improve performance after joining a large room when presence is enabled. ([\#9910](https://github.com/matrix-org/synapse/issues/9910), [\#9916](https://github.com/matrix-org/synapse/issues/9916)) - Support stable identifiers for [MSC1772](https://github.com/matrix-org/matrix-doc/pull/1772) Spaces. `m.space.child` events will now be taken into account when populating the experimental spaces summary response. Please see [the upgrade notes](https://github.com/matrix-org/synapse/blob/release-v1.34.0/UPGRADE.rst#upgrading-to-v1340) if you have customised `room_invite_state_types` in your configuration.
