- The `system:kube-controller-manager` ClusterRole lacks permission to `get` the `configmap` extension-apiserver-authentication. kube-controller-manager errors if run with a service account bound to the clusterrole.

### kubectl (CLI)

- The `horizontalpodautoscaling` and `clusterrole-aggregation` controllers now assume the `autoscaling/v1` and `rbac.authorization.k8s.io/v1` APIs are available. If you disable those APIs and do not want to run those controllers, exclude them by passing `--controllers=-horizontalpodautoscaling` or `--controllers=-clusterrole-aggregation` to `kube-controller-manager`.

    - `kubectl create clusterrolebinding anonymous-discovery --clusterrole=system:discovery --group=system:unauthenticated`
    - `kubectl create clusterrolebinding anonymous-access-review --clusterrole=system:basic-user --group=system:unauthenticated`

    * or grant self-deletion permission explicitly:
        * `kubectl create clusterrole self-deleting-nodes --verb=delete --resource=nodes`
        * `kubectl create clusterrolebinding self-deleting-nodes --clusterrole=self-deleting-nodes --group=system:nodes`

  * Update command invocations to pass separate --from-literal flags for each value

### RBAC

* Fix validation for HealthzBindAddress in kube-proxy when --healthz-port is set to 0 ([#66138](https://github.com/kubernetes/kubernetes/pull/66138), [@wsong](https://github.com/wsong))
* Role, ClusterRole and their bindings for cloud-provider is put under system namespace. Their addonmanager mode switches to EnsureExists. ([#67224](https://github.com/kubernetes/kubernetes/pull/67224), [@grayluck](https://github.com/grayluck))

- Migrated the `ClusterRole` aggregation controller (within `kube-controller-manager`) to use [contextual logging](https://k8s.io/docs/concepts/cluster-administration/system-logs/#contextual-logging). ([#113910](https://github.com/kubernetes/kubernetes/pull/113910), [@men...

* Adds configuration option for Swift object store container name to OpenStack Heat provider. ([#48281](https://github.com/kubernetes/kubernetes/pull/48281), [@hogepodge](https://github.com/hogepodge))
* Allow the system:heapster ClusterRole read access to deployments ([#48357](https://github.com/kubernetes/kubernetes/pull/48357), [@faraazkhan](https://github.com/faraazkhan))

    * `kubectl delete node/<nodeName>`
    * or grant self-deletion permission explicitly:
        * `kubectl create clusterrole self-deleting-nodes --verb=delete --resource=nodes`
        * `kubectl create clusterrolebinding self-deleting-nodes --clusterrole=self-deleting-nodes --group=system:nodes`
