* Restored the ability of kubectl running inside a pod to consume resource files specifying a different namespace than the one the pod is running in. ([#44862](https://github.com/kubernetes/kubernetes/pull/44862), [@liggitt](https://github.com/liggitt))

* Kubelet supports running mount utilities and final mount in a container instead running them on the host. ([#53440](https://github.com/kubernetes/kubernetes/pull/53440), [@jsafrane](https://github.com/jsafrane))
