Synapse 0.99.2 released!

2019-03-04 — General — Neil Johnson

Well now, what have we here? Synapse 0.99.2 is the latest in the 0.99.x series as we step ever closer to 1.0.

0.99.2 is an incremental release including a bunch of performance improvements, enhancements to room upgrades and generally a plethora of bug fixes.

The most important thing that admins should know is that prior to 1.0 landing later this month, it is essential that the federation API has a valid TLS certificate - self signed certificates will no longer be accepted. For more details see our handy guide. Failure to do this will result in being unable to federate with other 1.0 servers.

As ever, you can get the new update here or any of the sources mentioned at https://github.com/matrix-org/synapse. Note, Synapse is now available from PyPI, pick it up here. Also, check out our new Synapse installation guide page.
