- The `batch/v2alpha1.CronJob` is deprecated in favor of `batch/v1beta1`.

 - The RBAC v1alpha1 API group is deprecated in favor of RBAC v1.

- Improved PVC Protection Controller's scalability by batch-processing PVCs by namespace with lazy live pod listing. ([#125372](https://github.com/kubernetes/kubernetes/pull/125372), [@hungnguyen243](https://github.com/hungnguyen243)) [SIG Apps, Node, Storage and Testing]

* Federation: Add `batch/jobs` API objects to federation-apiserver ([#35943](https://github.com/kubernetes/kubernetes/pull/35943), [@jianhuiz](https://github.com/jianhuiz))

  Jobs that are tracked using this mechanism get the annotation `batch.kubernetes.io/job-tracking`. This is a temporary measure. Two releases after this feature graduates to beta, the annotation won't be added to Jobs anymore. ([#98817](https://github.com/kubernete...

- Kube-apiserver: fixes a 1.27+ regression in watch stability by serving watch requests without a resourceVersion from the watch cache by default, as in <1.27 (disabling the change in #115096 by default). This mitigates the impact of an etcd watch bug (https://github.com/etcd-io/etcd/pull/17555). If the 1.27 change in #115096 to serve these requests from underlying storage is still desired despite the impact on watch stability, it can be re-enabled with a `WatchFromStorageWithoutResourceVersion`...

- The watch API endpoints prefixed with `/watch` are deprecated and will be removed in a future release. These standard method for watching resources (supported since v1.0) is to use the list API endpoints with a `?watch=true` parameter. All client-go clients have used the parameter method since v1.6.0. ([#65147](https://github.com/kubernetes/kubernetes/pull/65147),...

*   Custom resources served by CustomResourceDefinition objects now support field selectors for `metadata.name` and `metadata.namespace`. Also fixed an issue with watching a single object; earlier versions could watch only a collection, and so a watch on an instance would fail.
