Synapse 1.61.0 (2022-06-14)
===========================

This release removes support for the non-standard feature known both as 'groups' and as 'communities', which have been superseded by *Spaces*.

See [the upgrade notes](https://github.com/matrix-org/synapse/blob/develop/docs/upgrade.md#upgrading-to-v1610)
for more details.

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

- Mention removed community/group worker endpoints in [upgrade.md](https://github.com/matrix-org/synapse/blob/develop/docs/upgrade.md#upgrading-to-v1610s). Contributed by @olmari. ([\matrix-org#13023](matrix-org#13023))

Synapse 1.61.0rc1 (2022-06-07)
==============================

Features
--------

- Add new `media_retention` options to the homeserver config for routinely cleaning up non-recently accessed media. ([\matrix-org#12732](matrix-org#12732), [\matrix-org#12972](matrix-org#12972), [\matrix-org#12977](matrix-org#12977))
- Experimental support for [MSC3772](matrix-org/matrix-spec-proposals#3772): Push rule for mutually related events. ([\matrix-org#12740](matrix-org#12740), [\matrix-org#12859](matrix-org#12859))
- 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). ([\matrix-org#12808](matrix-org#12808))
- Add storage and module API methods to get monthly active users (and their corresponding appservices) within an optionally specified time range. ([\matrix-org#12838](matrix-org#12838), [\matrix-org#12917](matrix-org#12917))
- Support the new error code `ORG.MATRIX.MSC3823.USER_ACCOUNT_SUSPENDED` from [MSC3823](matrix-org/matrix-spec-proposals#3823). ([\matrix-org#12845](matrix-org#12845), [\matrix-org#12923](matrix-org#12923))
- Add a configurable background job to delete stale devices. ([\matrix-org#12855](matrix-org#12855))
- Improve URL previews for pages with empty elements. ([\matrix-org#12951](matrix-org#12951))
- Allow updating a user's password using the admin API without logging out their devices. Contributed by @jcgruenhage. ([\matrix-org#12952](matrix-org#12952))

Bugfixes
--------

- Always send an `access_token` in `/thirdparty/` requests to appservices, as required by the [Application Service API specification](https://spec.matrix.org/v1.1/application-service-api/#third-party-networks). ([\matrix-org#12746](matrix-org#12746))
- Implement [MSC3816](matrix-org/matrix-spec-proposals#3816): sending the root event in a thread should count as having 'participated' in it. ([\matrix-org#12766](matrix-org#12766))
- Delete events from the `federation_inbound_events_staging` table when a room is purged through the admin API. ([\matrix-org#12784](matrix-org#12784))
- Fix a bug where we did not correctly handle invalid device list updates over federation. Contributed by Carl Bordum Hansen. ([\matrix-org#12829](matrix-org#12829))
- Fix a bug which allowed multiple async operations to access database locks concurrently. Contributed by @sumnerevans @ Beeper. ([\matrix-org#12832](matrix-org#12832))
- Fix an issue introduced in Synapse 0.34 where the `/notifications` endpoint would only return notifications if a user registered at least one pusher. Contributed by Famedly. ([\matrix-org#12840](matrix-org#12840))
- Fix a bug where servers using a Postgres database would fail to backfill from an insertion event when MSC2716 is enabled (`experimental_features.msc2716_enabled`). ([\matrix-org#12843](matrix-org#12843))
- Fix [MSC3787](matrix-org/matrix-spec-proposals#3787) rooms being omitted from room directory, room summary and space hierarchy responses. ([\matrix-org#12858](matrix-org#12858))
- Fix a bug introduced in Synapse 1.54.0 which could sometimes cause exceptions when handling federated traffic. ([\matrix-org#12877](matrix-org#12877))
- Fix a bug introduced in Synapse 1.59.0 which caused room deletion to fail with a foreign key violation error. ([\matrix-org#12889](matrix-org#12889))
- Fix a long-standing bug which caused the `/messages` endpoint to return an incorrect `end` attribute when there were no more events. Contributed by @Vetchu. ([\matrix-org#12903](matrix-org#12903))
- Fix a bug introduced in Synapse 1.58.0 where `/sync` would fail if the most recent event in a room was a redaction of an event that has since been purged. ([\matrix-org#12905](matrix-org#12905))
- Fix a potential memory leak when generating thumbnails. ([\matrix-org#12932](matrix-org#12932))
- Fix a long-standing bug where a URL preview would break if the image failed to download. ([\matrix-org#12950](matrix-org#12950))

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

- Fix typographical errors in documentation. ([\matrix-org#12863](matrix-org#12863))
- Fix documentation incorrectly stating the `sendToDevice` endpoint can be directed at generic workers. Contributed by Nick @ Beeper. ([\matrix-org#12867](matrix-org#12867))

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

- Remove support for the non-standard groups/communities feature from Synapse. ([\matrix-org#12553](matrix-org#12553), [\matrix-org#12558](matrix-org#12558), [\matrix-org#12563](matrix-org#12563), [\matrix-org#12895](matrix-org#12895), [\matrix-org#12897](matrix-org#12897), [\matrix-org#12899](matrix-org#12899), [\matrix-org#12900](matrix-org#12900), [\matrix-org#12936](matrix-org#12936), [\matrix-org#12966](matrix-org#12966))
- Remove contributed `kick_users.py` script. This is broken under Python 3, and is not added to the environment when `pip install`ing Synapse. ([\matrix-org#12908](matrix-org#12908))
- Remove `contrib/jitsimeetbridge`. This was an unused experiment that hasn't been meaningfully changed since 2014. ([\matrix-org#12909](matrix-org#12909))
- Remove unused `contrib/experiements/cursesio.py` script, which fails to run under Python 3. ([\matrix-org#12910](matrix-org#12910))
- Remove unused `contrib/experiements/test_messaging.py` script. This fails to run on Python 3. ([\matrix-org#12911](matrix-org#12911))

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

- Test Synapse against Complement with workers. ([\matrix-org#12810](matrix-org#12810), [\matrix-org#12933](matrix-org#12933))
- Reduce the amount of state we pull from the DB. ([\matrix-org#12811](matrix-org#12811), [\matrix-org#12964](matrix-org#12964))
- Try other homeservers when re-syncing state for rooms with partial state. ([\matrix-org#12812](matrix-org#12812))
- Resume state re-syncing for rooms with partial state after a Synapse restart. ([\matrix-org#12813](matrix-org#12813))
- Remove Mutual Rooms' ([MSC2666](matrix-org/matrix-spec-proposals#2666)) endpoint dependency on the User Directory. ([\matrix-org#12836](matrix-org#12836))
- Experimental: expand `check_event_for_spam` with ability to return additional fields. This enables spam-checker implementations to experiment with mechanisms to give users more information about why they are blocked and whether any action is needed from them to be unblocked. ([\matrix-org#12846](matrix-org#12846))
- Remove `dont_notify` from the `.m.rule.room.server_acl` rule. ([\matrix-org#12849](matrix-org#12849))
- Remove the unstable `/hierarchy` endpoint from [MSC2946](matrix-org/matrix-spec-proposals#2946). ([\matrix-org#12851](matrix-org#12851))
- Pull out less state when handling gaps in room DAG. ([\matrix-org#12852](matrix-org#12852), [\matrix-org#12904](matrix-org#12904))
- Clean-up the push rules datastore. ([\matrix-org#12856](matrix-org#12856))
- Correct a type annotation in the URL preview source code. ([\matrix-org#12860](matrix-org#12860))
- Update `pyjwt` dependency to [2.4.0](https://github.com/jpadilla/pyjwt/releases/tag/2.4.0). ([\matrix-org#12865](matrix-org#12865))
- Enable the `/account/whoami` endpoint on synapse worker processes. Contributed by Nick @ Beeper. ([\matrix-org#12866](matrix-org#12866))
- Enable the `batch_send` endpoint on synapse worker processes. Contributed by Nick @ Beeper. ([\matrix-org#12868](matrix-org#12868))
- Don't generate empty AS transactions when the AS is flagged as down. Contributed by Nick @ Beeper. ([\matrix-org#12869](matrix-org#12869))
- Fix up the variable `state_store` naming. ([\matrix-org#12871](matrix-org#12871))
- Faster room joins: when querying the current state of the room, wait for state to be populated. ([\matrix-org#12872](matrix-org#12872))
- Avoid running queries which will never result in deletions. ([\matrix-org#12879](matrix-org#12879))
- Use constants for EDU types. ([\matrix-org#12884](matrix-org#12884))
- Reduce database load of `/sync` when presence is enabled. ([\matrix-org#12885](matrix-org#12885))
- Refactor `have_seen_events` to reduce memory consumed when processing federation traffic. ([\matrix-org#12886](matrix-org#12886))
- Refactor receipt linearization code. ([\matrix-org#12888](matrix-org#12888))
- Add type annotations to `synapse.logging.opentracing`. ([\matrix-org#12894](matrix-org#12894))
- Remove PyNaCl occurrences directly used in Synapse code. ([\matrix-org#12902](matrix-org#12902))
- Bump types-jsonschema from 4.4.1 to 4.4.6. ([\matrix-org#12912](matrix-org#12912))
- Rename storage classes. ([\matrix-org#12913](matrix-org#12913))
- Preparation for database schema simplifications: stop reading from `event_edges.room_id`. ([\matrix-org#12914](matrix-org#12914))
- Check if we are in a virtual environment before overriding the `PYTHONPATH` environment variable in the demo script. ([\matrix-org#12916](matrix-org#12916))
- Improve the logging when signature checks on events fail. ([\matrix-org#12925](matrix-org#12925))
