* Exec authenticator plugin supports TLS client certificates. ([#61803](https://github.com/kubernetes/kubernetes/pull/61803), [@awly](https://github.com/awly))
* The `serverAddressByClientCIDRs` property in `metav1.APIGroup`(discovery API) is now optional instead of required. ([#61963](https://github.com/kubernetes/kubernetes/pull/61963), [@roycaihw](https://github.com/roycaihw))

- `kubectl api-resources` now prints the API version (as 'API group/version', same as output of `kubectl api-versions`). The column APIGROUP is now APIVERSION ([#95253](https://github.com/kubernetes/kubernetes/pull/95253), [@sallyom](https://github.com/sallyom)) [SIG CLI]

* kubectl now supports validation of nested objects with different ApiGroups (e.g. objects in a List) ([#25172](https://github.com/kubernetes/kubernetes/pull/25172), [@pwittrock](https://github.com/pwittrock))

* `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"`.
