Synapse 1.30.0 (2021-03-22) =========================== Note that this release deprecates the ability for appservices to call `POST /_matrix/client/r0/register` without the body parameter `type`. Appservice developers should use a `type` value of `m.login.application_service` as per [the spec](https://matrix.org/docs/spec/application_service/r0.1.2#server-admin-style-permissions). In future releases, calling this endpoint with an access token - but without a `m.login.application_service` type - will fail. No significant changes. Synapse 1.30.0rc1 (2021-03-16) ============================== Features -------- - Add prometheus metrics for number of users successfully registering and logging in.
