v1.32.0rc1

Synapse 1.32.0rc1 (2021-04-13)

Note: This release requires Python 3.6+ and Postgres 9.6+ or SQLite 3.22+.

This release removes the deprecated GET /_synapse/admin/v1/users/<user_id> admin API. Please use the v2 API instead, which has improved capabilities.

This release requires Application Services to use type m.login.application_service when registering users via the /_matrix/client/r0/register endpoint to comply with the spec. Please ensure your Application Services are up to date.
