Synapse 1.26.0 is now available!

Note: This release includes a new database schema version. If you need to roll back to Synapse 1.25.0, you will also need to follow the associated database downgrade instructions.

In addition to a truckload of refactoring and general improvements, Synapse 1.26.0 includes three major new features:

  1. A brand new algorithm for calculating the auth chain difference, which should dramatically improve worst case performance during state resolution (#8622).
  2. Initial support for enabling multiple OpenID Connect providers, paving the way for proper multi-provider social login workflows.
  3. A significant speed-up to redaction performance in large rooms.

It also brings several improvements to Admin APIs:

We've also made it possible to offload several additional APIs to worker processes, including read receipts and account data persistence, further improving Synapse's scalability.

See the full changelog for more.

Lastly, a reminder: we have deprecated Python 3.5 and PostgreSQL 9.5 and will cease support at the end of March. Due to deprecations in our Python tooling, we were unable to produce a binary package for Ubuntu 16.04 LTS (Xenial) in time for this release. We have resolved this for 1.27.

Synapse is a Free and Open Source Software project, and we'd like to extend our thanks to everyone who contributed to this release, including 0xflotus, chris-ruecker, dklimpel, emelie-qis, jerinjtitus, and tzyl.
