and `apiserver_webhooks_x509_missing_san_total`. This metric measures a number of connections to webhooks/aggregated API servers that use certificates without Subject Alternative Names. It being non-zero is a warning sign that these connections will stop functioning in the future since Golang is going to deprecate x509 certificate subject Common Names for server hostname verification.

- `Kubectl set resources` will no longer return an error if passed an empty change for a resource. `kubectl set subject` will no longer return an error if passed an empty change for a resource.

- Kubeadm: changed the "system:masters" Group in the apiserver-kubelet-client.crt certificate Subject to be "kubeadm:cluster-admins" which is a less privileged Group. ([#121837](https://github.com/kubernetes/kubernetes/pull/121837), [@neolit123](https://github.com/neolit123))

    * `kubectl auth can-i` now supports non-resource URLs ([#46432](https://github.com/kubernetes/kubernetes/pull/46432), [@CaoShuFeng](https://github.com/CaoShuFeng))

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

* `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"`.
