 Bugfixes
 --------
 
 - Fix a bug introduced in v1.19.0 where appservices with ratelimiting disabled would still be ratelimited when joining rooms. ([\#8139](https://github.com/matrix-org/synapse/issues/8139))
 - Fix a bug introduced in v1.19.0 that would cause e.g. profile updates to fail due to incorrect application of rate limits on join requests. ([\#8153](https://github.com/matrix-org/synapse/issues/8153))
