Synapse 1.56.0rc1 (2022-03-29)
==============================

Features
--------

- Allow registering server administrators using the module API. Contributed by Famedly. ([\#12250](#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](#12087))
- Fix a long-standing bug where events from ignored users would still be considered for relations. ([\#12227](#12227), [\#12232](#12232), [\#12285](#12285))
- Fix a bug introduced in Synapse 1.53.0 where an unnecessary query could be performed when fetching bundled aggregations for threads. ([\#12228](#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](#12261))

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

- Fix the link to the module documentation in the legacy spam checker warning message. ([\#12231](#12231))
