gate UnversionedKubeletConfigMap. When this feature is enabled kubeadm will start using a new naming format for the ConfigMap where it stores the KubeletConfiguration structure. The old format included the Kubernetes version - "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...

`/var/lib/kubelet/pod_status_manager_state` is now can always be read back after kubelet restart.
  
  Since the checkpoint format was changed to fix the issue, if you are using the feature `InPlacePodVerticalScaling`, please clean up the state file `/var/lib/kubelet/pod_status_manager_state` when upgrading the kubelet as failrue to do it will lead to incompatible state formats and kubelet's failure to start.

* RBAC objects are now stored in etcd in v1 format. After completing an upgrade to 1.9, RBAC objects (Roles, RoleBindings, ClusterRoles, ClusterRoleBindings) should be migrated to ensure all persisted objects are written in `v1` format, prior to `v1alpha1` support being removed in a future release. ([#52950](https://github.com/kubernetes/kubernetes/pull/52950), [@liggitt](https://github.com/liggitt))...

- Changed handling of CustomResourceDefinitions with unrecognized formats. Writing a schema with an unrecognized formats now triggers a warning (the write is still accepted).

- The underlying format of the `CPUManager` state file has changed. Upgrades should be seamless, but any third-party tools that rely on reading the previous format need to be updated.

### Auth

* [GA] The RBAC API group has been promoted from v1beta1 to v1. No API changes were introduced.

* [beta] Advanced auditing has been promoted from alpha to beta. The webhook and logging policy formats have changed since alpha, and may require modification.

- Added warnings to the Services API. Kubernetes now warns for Services in the case of:
  - IPv4 addresses with leading zeros
  - IPv6 address in non-canonical format (RFC 5952) ([#114505](https://github.com/kubernetes/kubernetes/pull/114505), [@aojea](https://github.com/aojea))

    * `kubectl create secret` has a new option `--from-env-file` that populates a secret from file which follows a key=val format for each line.

  * Printing/describe

- Kubeadm: implemented structured output of 'kubeadm token list' in JSON, YAML, Go template and JsonPath formats ([#78764](https://github.com/kubernetes/kubernetes/pull/78764), [@bart0sh](https://github.com/bart0sh))
