Synapse 1.35.0 (2021-06-01)

Note that the tag and docker images for v1.35.0rc3 were incorrectly built. If you are experiencing issues with either, it is recommended to upgrade to the equivalent tag or docker image for the v1.35.0 release.

Deprecations and Removals

• The core Synapse development team plan to drop support for the unstable API of MSC2858, including the undocumented experimental.msc2858_enabled config option, in August 2021. Client authors should ensure that their clients are updated to use the stable API (which has been supported since Synapse 1.30) well before that time, to give their users time to upgrade. (#10101)

Bugfixes

• Fixed a bug causing replication requests to fail when receiving a lot of events via federation. Introduced in v1.33.0. (#10082)
• Fix HTTP response size limit to allow joining very large rooms over federation. Introduced in v1.33.0. (#10093)
