[keycloak-user] Where did "Requesting Entitlements" go?

Hello everyone, in keycloak 3.3 one could easily request entitlements as described here: https://www.keycloak.org/docs/3.3/authorization_services/topics/service/e... In keycloak 4.0 this options seems to be gone. Where did it go? What is the new URL? The old way now returns a 404. And BTW: Where are these breaking changes documented? I can't find them in the release notes, and checking all the issues seems a little cumbersome. Best Regards Stefan
