Synapse 1.56.0rc1 (2022-03-29)

==============================
 
 Features
 --------
 
 - Allow modules to store already existing 3PID associations. ([\#12195](https://github.com/matrix-org/synapse/issues/12195))
 - Allow registering server administrators using the module API. Contributed by Famedly. ([\#12250](https://github.com/matrix-org/synapse/issues/12250))
 
 Bugfixes
 --------
 
 - Fix a long-standing bug which caused the `/_matrix/federation/v1/state` and `/_matrix/federation/v1/state_ids` endpoints to return incorrect or invalid data when called for an event which we have stored as an "outlier". ([\#12087](https://github.com/matrix-org/synapse/issues/12087))
 - Fix a long-standing bug where events from ignored users would still be considered for relations. ([\#12227](https://github.com/matrix-org/synapse/issues/12227), [\#12232](https://github.com/matrix-org/synapse/issues/12232), [\#12285](https://github.com/matrix-org/synapse/issues/12285))
 - Fix a bug introduced in Synapse 1.53.0 where an unnecessary query could be performed when fetching bundled aggregations for threads. ([\#12228](https://github.com/matrix-org/synapse/issues/12228))
 - Fix a bug introduced in Synapse 1.52.0 where admins could not deactivate and GDPR-erase a user if Synapse was configured with limits on avatars. ([\#12261](https://github.com/matrix-org/synapse/issues/12261))
 
 Improved Documentation
 ----------------------
 
 - Fix the link to the module documentation in the legacy spam checker warning message. ([\#12231](https://github.com/matrix-org/synapse/issues/12231))
 - Remove incorrect prefixes in the worker documentation for some endpoints. ([\#12243](https://github.com/matrix-org/synapse/issues/12243))
 - Correct `check_username_for_spam` annotations and docs. ([\#12246](https://github.com/matrix-org/synapse/issues/12246))
 - Correct Authentik OpenID typo, and add notes on troubleshooting. Contributed by @IronTooch. ([\#12275](https://github.com/matrix-org/synapse/issues/12275))
 - HAProxy reverse proxy guide update to stop sending IPv4-mapped address to homeserver. Contributed by @villepeh. ([\#12279](https://github.com/matrix-org/synapse/issues/12279))
 
 Internal Changes
 ----------------
 
 - Rename `shared_rooms` to `mutual_rooms` ([MSC2666](https://github.com/matrix-org/matrix-doc/pull/2666)), as per proposal changes. ([\#12036](https://github.com/matrix-org/synapse/issues/12036))

 - Refactor `create_new_client_event` to use a new parameter, `state_event_ids`, which accurately describes the usage with [MSC2716](https://github.com/matrix-org/matrix-doc/pull/2716) instead of abusing `auth_event_ids`. ([\#12083](https://github.com/matrix-org/synapse/issues/12083), [\#12304](https://github.com/matrix-org/synapse/issues/12304))
