[Synapse 1.22.0](https://github.com/matrix-org/synapse/releases/tag/v1.22.0) now available!
|
|
|
|
This release focused on improving Synapse's horizontal scalability, including:
|
|
|
|
* Support for running background tasks in separate worker processes.
|
|
* Fixes to sharded event persisters, which were experimentally introduced in 1.21.0.
|
|
* Fixing a message duplication bug with worker-based deployments. ([\#8476](https://github.com/matrix-org/synapse/issues/8476))
|
|
|
|
Synapse 1.22.0 also has a few other notable changes:
|
|
|
|
* Defaulting to [version 6](https://matrix.org/docs/spec/rooms/v6) rooms, per [MSC2788](https://github.com/matrix-org/matrix-doc/pull/2788/).
|
|
* Initial support for three new experimental MSCs:
|
|
* [MSC2732](https://github.com/matrix-org/matrix-doc/pull/2732): Supporting olm fallback keys
|
|
* [MSC2697](https://github.com/matrix-org/matrix-doc/pull/2697): Supporting device dehydration
|
|
* [MSC2409](https://github.com/matrix-org/matrix-doc/pull/2409): Allowing appservices to receive ephemeral events like read receipts, presence, and typing indicators.
|
|
* Multi-arch Docker images, covering `arm64` and `arm/v7` in addition to `amd64`.
