### **Networking**
#### Network Policy
* [stable] [NetworkPolicy](https://kubernetes.io/docs/concepts/services-networking/network-policies/) promoted to GA.
  * Additionally adds short name "netpol" for networkpolicies ([#42241](https://github.com/kubernetes/kubernetes/pull/42241), [@xiangpengzhao](https://github.com/xiangpengzhao))


#### Load Balancing

* kubeadm: fix "upgrade plan" not defaulting to a "stable" version if no version argument is passed ([#75900](https://github.com/kubernetes/kubernetes/pull/75900), [@neolit123](https://github.com/neolit123))

  /**
   * An unmodifiable view of a set which may be backed by other sets; this view will change as the
   * backing sets do. Contains methods to copy the data into a new set which will then remain
   * stable. There is usually no reason to retain a reference of type {@code SetView}; typically,
   * you either use it as a plain {@link Set}, or immediately invoke {@link #immutableCopy} or

		// is always going to be in-memory as we cannot re-read from what we
		// wrote to disk - since that amounts to "copying" from a "copy"
		// instead of "copying" from source, we need the stream to be seekable
		// to ensure that we can make fan-out calls concurrently.

    *   reflector_watch_duration_seconds
    *   reflector_watches_total
    * While this is a backwards-incompatible change, it would have been impossible to setup reliable monitoring around these metrics since the labels were not stable.

### **Storage**

*   [stable] `PersistentVolume` and `PersistentVolumeClaim` objects must now have a capacity greater than zero.
*   [stable] Mutation of `PersistentVolumeSource` after creation is no longer allowed

* `kubectl api-resources` now supports filtering to resources supporting specific verbs, and can output fully qualified resource names suitable for combining with commands like `kubectl get` ([#63254](https://github.com/kubernetes/kubernetes/pull/63254), [@liggitt](https://github.com/liggitt))
