Synapse 1.34.0 (2021-05-17)
===========================

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.

No significant changes since v1.34.0rc1.

Synapse 1.34.0rc1 (2021-05-12)
==============================

Features
--------

- Add experimental option to track memory usage of the caches. ([\#9881](matrix-org/synapse#9881))
- Add support for `DELETE /_synapse/admin/v1/rooms/<room_id>`. ([\#9889](matrix-org/synapse#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](matrix-org/synapse#9902))
- Improve performance of sending events for worker-based deployments using Redis. ([\#9905](matrix-org/synapse#9905), [\#9950](matrix-org/synapse#9950), [\#9951](matrix-org/synapse#9951))
- Improve performance after joining a large room when presence is enabled. ([\#9910](matrix-org/synapse#9910), [\#9916](matrix-org/synapse#9916))
- Support stable identifiers for [MSC1772](matrix-org/matrix-spec-proposals#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. ([\#9915](matrix-org/synapse#9915), [\#9966](matrix-org/synapse#9966))
- Improve performance of backfilling in large rooms. ([\#9935](matrix-org/synapse#9935))
- Add a config option to allow you to prevent device display names from being shared over federation. Contributed by @aaronraimist. ([\#9945](matrix-org/synapse#9945))
- Update support for [MSC2946](matrix-org/matrix-spec-proposals#2946): Spaces Summary. ([\#9947](matrix-org/synapse#9947), [\#9954](matrix-org/synapse#9954))

Bugfixes
--------

- Fix a bug introduced in v1.32.0 where the associated connection was improperly logged for SQL logging statements. ([\#9895](matrix-org/synapse#9895))
- Correct the type hint for the `user_may_create_room_alias` method of spam checkers. It is provided a `RoomAlias`, not a `str`. ([\#9896](matrix-org/synapse#9896))
- Fix bug where user directory could get out of sync if room visibility and membership changed in quick succession. ([\#9910](matrix-org/synapse#9910))
- Include the `origin_server_ts` property in the experimental [MSC2946](matrix-org/matrix-spec-proposals#2946) support to allow clients to properly sort rooms. ([\#9928](matrix-org/synapse#9928))
- Fix bugs introduced in v1.23.0 which made the PostgreSQL port script fail when run with a newly-created SQLite database. ([\#9930](matrix-org/synapse#9930))
- Fix a bug introduced in Synapse 1.29.0 which caused `m.room_key_request` to-device messages sent from one user to another to be dropped. ([\#9961](matrix-org/synapse#9961), [\#9965](matrix-org/synapse#9965))
- Fix a bug introduced in v1.27.0 preventing users and appservices exempt from ratelimiting from creating rooms with many invitees. ([\#9968](matrix-org/synapse#9968))

Updates to the Docker image
---------------------------

- Add `startup_delay` to docker healthcheck to reduce waiting time for coming online and update the documentation with extra options. Contributed by @maquis196. ([\#9913](matrix-org/synapse#9913))

Improved Documentation
----------------------

- Add `port` argument to the Postgres database sample config section. ([\#9911](matrix-org/synapse#9911))

Deprecations and Removals
-------------------------

- Mark as deprecated `POST /_synapse/admin/v1/rooms/<room_id>/delete`. ([\#9889](matrix-org/synapse#9889))

Internal Changes
----------------

- Reduce the length of Synapse's access tokens. ([\#5588](matrix-org/synapse#5588))
- Export jemalloc stats to Prometheus if it is being used. ([\#9882](matrix-org/synapse#9882))
- Add type hints to presence handler. ([\#9885](matrix-org/synapse#9885))
- Reduce memory usage of the LRU caches. ([\#9886](matrix-org/synapse#9886))
- Add type hints to the `synapse.handlers` module. ([\#9896](matrix-org/synapse#9896))
- Time response time for external cache requests. ([\#9904](matrix-org/synapse#9904))
- Minor fixes to the `make_full_schema.sh` script. ([\#9931](matrix-org/synapse#9931))
- Move database schema files into a common directory. ([\#9932](matrix-org/synapse#9932))
- Add debug logging for lost/delayed to-device messages. ([\#9959](matrix-org/synapse#9959))

Note that this makes modifications to the underlying MSCs as well. These are intended to be minor edits to aid clarity/accuracy of the MSCs, as per the proposal process. Functionally, clients and servers might need to change their behaviour slightly as is expected of implementing this stuff early. Synapse has these changes (alongside backwards compatibility) here: matrix-org/synapse#11667
