We released Synapse v0.27.2 today (the first stable release in the 0.27.x series) - it contains loads of work since Synapse v0.26 back in January.  The main highlights are:

  • All the perf improvements which we've been landing as we race to keep the matrix.org homeserver in the face of ever-expanding traffic levels over the last few months
  • Support for custom storage providers for media repository.
  • Ability to limit the email addresses allowed to register on your HS, and ability to limit the homeservers your homeserver is allowed to federate with
  • All new purge API - letting you purge history by date as well as by event (and having a nice new async way of doing it)
  • Make search work again!!! (by switching from GIST to GIN indexes)
And a few release notes worth calling out:
  • The common case for running Synapse is not to run separate workers, but for those that do, be aware that synctl no longer starts the main synapse when using -a option with workers. A new worker file should be added with worker_app: synapse.app.homeserver.
  • This release also begins the process of renaming a number of the metrics reported to prometheus. See docs/metrics-howto.rst  Note that the v0.28.0 release will remove the deprecated metric names.

As always, you can get it from https://github.com/matrix-org/synapse/releases/tag/v0.27.2

thanks for flying Matrix!
