 # Synapse 1.139.0 (2025-09-30)
 
+### `/register` requests from old application service implementations may break when using MAS
+
+If you are using Matrix Authentication Service (MAS), as of this release any
+Application Services that do not set `inhibit_login=true` when calling `POST
+/_matrix/client/v3/register` will receive the error
+`IO.ELEMENT.MSC4190.M_APPSERVICE_LOGIN_UNSUPPORTED` in response. Please see [the
+upgrade
+notes](https://element-hq.github.io/synapse/develop/upgrade.html#register-requests-from-old-application-service-implementations-may-break-when-using-mas)
+for more information.
