- Added scheduler preemption support for pods using `ReadWriteOncePod` PVCs ([#114051](https://github.com/kubernetes/kubernetes/pull/114051), [@chrishenzie](https://github.com/chrishenzie))

- Graduated API List chunking (aka pagination) feature to `stable`. ([#119503](https://github.com/kubernetes/kubernetes/pull/119503), [@wojtek-t](https://github.com/wojtek-t))
- Graduated the `ReadWriteOncePod` feature gate to `GA`. ([#121077](https://github.com/kubernetes/kubernetes/pull/121077), [@chrishenzie](https://github.com/chrishenzie))
- Graduated the following kubelet resource metrics to **general availability**:

										Default: "",
										Type:    []string{"string"},

`-o context` options. This is typical for storage backends that provide volumes as filesystems on block devices or as independent shared volumes. Kubernetes will call NodeStage / NodePublish with \"-o context=xyz\" mount option when mounting a ReadWriteOncePod volume used in Pod that has explicitly set SELinux context. In the future, it may be expanded to other volume AccessModes. In any case, Kubernetes will ensure that the volume is mounted only with a single SELinux context.\n\nWhen \"false\", Kubernetes...
