Synapse 1.25.0 is now available! With this release, we are deprecating Python 3.5 and PostgreSQL 9.5 and will cease producing binary packages for Debian 9 (Stretch) and Ubuntu 16.04 (Xenial) after a transition period which lasts through March 2021. See the changelog for further details.

We are also deprecating the Purge Room and Shutdown Room Admin APIs and will remove them in a future release. Please update your code to use the Delete Room Admin API instead.

Synapse 1.25.0 brings over a month's worth of improvements, including:

• The ability for users to pick their own username when using Single Sign-On, right from within Synapse.
• Support for async Python methods in custom spam checker modules.
• New ways to restrict allowed IP address ranges for outgoing requests from Synapse.
• Significantly faster v2 state resolution on rooms with large numbers of power level events, which are common in some types of bridged IRC rooms.

See the full changelog and upgrade notes for more.
