- Promote Cronjobs storage version to `batch/v1`. ([#102363](https://github.com/kubernetes/kubernetes/pull/102363), [@mengjiao-liu](https://github.com/mengjiao-liu))
- Promote `CronJobControllerV2` flag to GA, with removal in 1.23. ([#102529](https://github.com/kubernetes/kubernetes/pull/102529), [@soltysh](https://github.com/soltysh))

### 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.

* The Sysctls experimental feature has been promoted to beta (enabled by default via the `Sysctls` feature flag). PodSecurityPolicy and Pod objects now have fields for specifying and controlling sysctls. Alpha sysctl annotations will be ignored by 1.11+ kubelets. All alpha sysctl annotations in existing...

### Apps

The core workloads API, which is composed of the DaemonSet, Deployment, ReplicaSet, and StatefulSet kinds, has been promoted to GA stability in the apps/v1 group version. As such, the apps/v1beta2 group version is deprecated, and all new code should use the kinds in the apps/v1 group version.

### Auth

the high availability use cases have been given priority for 1.15.

kubeadm, the cluster lifecycle building block, continues to receive features and stability work required for bootstrapping production clusters efficiently. kubeadm has promoted high availability (HA) capability to beta, allowing users to use the familiar `kubeadm init` and `kubeadm join` commands to [configure and deploy an HA control plane](https://kubernetes.io/docs/setup/production-environment/tools/kubeadm/high-availability/)....

### Other (Cleanup or Flake)

- 'Promoted `cronjob_job_creation_skew` metric to stable to follow the cronjob v2 controller,
  the following metrics had their name updated to match metrics API guidelines:
    - `cronjob_job_creation_skew_duration_seconds` -> `job_creation_skew_duration_seconds`.' ([#113008](https://github.com/kubernetes/kubernetes/pull/113008), [@soltysh](https://github.com/soltysh))
