*   The EvictionHard, EvictionSoft, EvictionSoftGracePeriod, EvictionMinimumReclaim, SystemReserved, and KubeReserved fields in the KubeletConfiguration object (`kubeletconfig/v1alpha1`) are now of type map[string]string, which facilitates writing JSON and YAML files. ([#54823](https://github.com/kubernetes/kubernetes/pull/54823),[ @mtaufen](https://github.com/mtaufen))

* Log audit backend can now be configured to perform batching before writing events to disk. ([#60237](https://github.com/kubernetes/kubernetes/pull/60237), [@crassirostris](https://github.com/crassirostris))

#### CLI Changes

- [alpha] `kubectl` plugins: `kubectl` now allows binary extensibility. You can extend the default set of `kubectl` commands by writing plugins
  that provide new subcommands. Refer to the documentation for more information.

- `kubectl rollout` and `rollback` now support StatefulSet.

- `kubeadm`: speedup init by 0s or 20s. kubelet-start phase is now after etcd
  and control-plane phases, removing a race condition between kubelet looking for
  static pod manifests and kubeadm writing them. ([#117984](https://github.com/kubernetes/kubernetes/pull/117984), [@champtar](https://github.com/champtar))

* Fixes a NPD bug on GCI, so that it disables glog writing to files for log-counter ([#76211](https://github.com/kubernetes/kubernetes/pull/76211), [@wangzhen127](https://github.com/wangzhen127))

* Increase Azure default maximumLoadBalancerRuleCount to 250. ([#72621](https://github.com/kubernetes/kubernetes/pull/72621), [@feiskyer](https://github.com/feiskyer))
* Fixes a NPD bug on GCI, so that it disables glog writing to files for log-counter ([#76211](https://github.com/kubernetes/kubernetes/pull/76211), [@wangzhen127](https://github.com/wangzhen127))

* [metrics-server addon] Restore connecting to nodes via IP addresses ([#76819](https://github.com/kubernetes/kubernetes/pull/76819), [@serathius](https://github.com/serathius))

"kube-system/kubelet-config-1.22", while the new format does not - "kube-system/kubelet-config". A similar formatting change is done for the related RBAC rules. The old format is now DEPRECATED and will be removed after the feature graduates to GA. When writing the ConfigMap kubeadm (init, upgrade apply) will respect the value of UnversionedKubeletConfigMap, while when reading it (join, reset, upgrade), it would attempt to use new format first and fallback to the legacy format if needed. ([#105741](http...

- Add Pre-filter extension point to the scheduling framework. ([#78005](https://github.com/kubernetes/kubernetes/pull/78005), [@ahg-g](https://github.com/ahg-g))
- Add support for writing out of tree custom scheduler plugins. ([#78162](https://github.com/kubernetes/kubernetes/pull/78162), [@hex108](https://github.com/hex108))

### Storage

- The `ServerSideFieldValidation` feature has graduated to beta and is now enabled by default. Kubectl 1.24 and newer will use server-side validation instead of client-side validation when writing to API servers with the feature enabled.
