* `v1beta1` RoleBinding/ClusterRoleBinding subjects changed `apiVersion` to `apiGroup` to fully-qualify a subject. ServiceAccount subjects default to an apiGroup of `""`, User and Group subjects default to an apiGroup of `"rbac.authorization.k8s.io"`. ([#41184](https://github.com/kubernetes/kubernetes/pull/41184), [@liggitt](https://github.com/liggitt))

  remove unused rules immediately once they are no longer used.)

  (The threshold for "large" used here is currently "1000 endpoints" but
  this is subject to change.) ([#110334](https://github.com/kubernetes/kubernetes/pull/110334), [@danwinship](https://github.com/danwinship))

- Add auth API to get self subject attributes (new selfsubjectreviews API is added). 

  - Use of the `--node-labels` flag to set labels under the `kubernetes.io/` and `k8s.io/` prefix will be subject to restriction by the `NodeRestriction` admission plugin in future releases. [See admission plugin documentation](https://kubernetes.io/docs/reference/access-authn-authz/admission-controllers/#noderestriction) for allowed labels. ([#68267](https:...

- Replaced *_admission_latencies_milliseconds_summary and *_admission_latencies_milliseconds metrics because they were reporting seconds rather than milliseconds. They were also subject to multiple naming guideline violations (units should be in base units and "duration" is the best practice labelling to measure the time a request takes). Please convert to use *_admission_duration_seconds and *_admission_duration_seconds_summary,...

* `set selector` and `set subject` no longer print "running in local/dry-run mode..." at the top, so their output can be piped as valid yaml or json ([#46507](https://github.com/kubernetes/kubernetes/pull/46507), [@bboreham](https://github.com/bboreham))
