Synapse 1.31.0rc1 (2021-03-30)

Note: As announced in v1.25.0, and in line with the deprecation policy for platform dependencies, this is the last release to support Python 3.5 and PostgreSQL 9.5. Future versions of Synapse will require Python 3.6+ and PostgreSQL 9.6+.

This is also the last release that the Synapse team will be publishing packages for Debian Stretch and Ubuntu Xenial.

Improved Documentation

• Clarify that register_new_matrix_user is present also when installed via non-pip package. (#9074)

Internal Changes

• Preparatory steps for removing redundant outlier data from event_json.internal_metadata column. (#9411)
