Synapse 1.81.0rc2 (2023-04-06)

==============================

Synapse now attempts the versioned appservice paths before falling back to the
[legacy paths](https://spec.matrix.org/v1.6/application-service-api/#legacy-routes).
Usage of the legacy routes should be considered deprecated.

Additionally, Synapse has supported sending the application service access token
via [the `Authorization` header](https://spec.matrix.org/v1.6/application-service-api/#authorization)
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.
