* Disallow PriorityClass names with 'system-' prefix for user defined priority classes. ([#59382](https://github.com/kubernetes/kubernetes/pull/59382), [@bsalamat](https://github.com/bsalamat))

  * For alpha, this feature increases only the size of the underlying volume. It does not support resizing the file system.

  * For alpha, volume resizing supports only Gluster volumes.

* [alpha] Provide capacity isolation and resource management for local ephemeral storage

file is now deployed. The User in `admin.conf` is now bound to a new RBAC Group `kubeadm:cluster-admins` that has `cluster-admin` `ClusterRole` access. The User in `super-admin.conf` is now bound to the `system:masters` built-in super-powers / break-glass Group that can bypass RBAC. Before this change, the default `admin.conf` was bound to `system:masters` Group, which was undesired. Executing `kubeadm init phase kubeconfig all` or just `kubeadm init` will now generate the new `super-admin.conf` file....

* Allow DNS resolution of service name for COS using containerized mounter.  It fixed the issue with DNS resolution of NFS and Gluster services. ([#51645](https://github.com/kubernetes/kubernetes/pull/51645), [@jingxu97](https://github.com/jingxu97))

### Alpha

- You can now create a non-preempting Pod priority (NonPreemptingPriority). If set on a class, the pod will continue to be prioritized above queued pods of a lesser class, but will not preempt running pods. ([#74614](https://github.com/kubernetes/kubernetes/pull/74614), [@denkensk](https://github.com/denkensk))

### Volumes
* **[stable]** StorageClass API is promoted to v1 (storage.k8s.io/v1).
* **[stable]** Default storage classes are deployed during installation on Azure, AWS, GCE, OpenStack and vSphere.
* **[stable]** Added ability to populate environment variables from a configmap or secret.
