v1.81.0

Synapse 1.81.0 (2023-04-11)

Synapse now attempts the versioned appservice paths before falling back to the legacy paths. Usage of the legacy routes should be considered deprecated.

Additionally, Synapse has supported sending the application service access token via the Authorization header since v1.70.0. For backwards compatibility it is also sent as the access_token query parameter. This is insecure and should be considered deprecated.

A future version of Synapse (v1.88.0 or later) will remove support for legacy application service routes and query parameter authorization.

No significant changes since 1.81.0rc2.
