Kubernetes 1.24 offers beta support for publishing its APIs in the [OpenAPI v3 format](https://github.com/kubernetes/enhancements/issues/2896).

### Storage Capacity and Volume Expansion Are Generally Available

[Storage capacity tracking](https://github.com/kubernetes/enhancements/issues/1472)
supports exposing currently available storage capacity via [CSIStorageCapacity objects](https://kubernetes.io/docs/concepts/storage/storage-capacity/#api)

* Add support for NFSv4 and GlusterFS in GCI base image ([#37336](https://github.com/kubernetes/kubernetes/pull/37336), [@jingxu97](https://github.com/jingxu97))
* Use generous limits in the resource usage tracking tests ([#36623](https://github.com/kubernetes/kubernetes/pull/36623), [@yujuhong](https://github.com/yujuhong))



# v1.4.6

* Default host user namespace via experimental flag ([#31169](https://github.com/kubernetes/kubernetes/pull/31169), [@pweil-](https://github.com/pweil-))
* Use generous limits in the resource usage tracking tests ([#36623](https://github.com/kubernetes/kubernetes/pull/36623), [@yujuhong](https://github.com/yujuhong))

  Jobs tracked with finalizers have the annotation batch.kubernetes.io/job-tracking.
  If the annotation is present and the user attempts to remove it, the control plane adds it back.
  The annotation `batch.kubernetes.io/job-tracking` is now deprecated.

     * Read operations can thus proceed without locking, but rely on selected uses of volatiles to
     * ensure that completed write operations performed by other threads are noticed. For most
     * purposes, the "count" field, tracking the number of elements, serves as that volatile
     * variable ensuring visibility. This is convenient because this field needs to be read in many
     * read operations anyway:
     *

    /** The key of the configuration. e.g. 3600 */
    String COOKIE_DEFAULT_EXPIRE = "cookie.default.expire";

    /** The key of the configuration. e.g. cookie */
    String SESSION_TRACKING_MODES = "session.tracking.modes";

    /** The key of the configuration. e.g. 25 */
    String PAGING_PAGE_SIZE = "paging.page.size";

    /** The key of the configuration. e.g. 5 */

- Client-go/tools/record.Broadcaster: Fixed automatic shutdown on WithContext cancellation. ([#124635](https://github.com/kubernetes/kubernetes/pull/124635), [@pohly](https://github.com/pohly))
- Do not remove the "batch.kubernetes.io/job-tracking" finalizer from a Pod, in a corner
  case scenario, when the Pod is controlled by an API object which is not a batch Job

- Fix job tracking with finalizers for more than 500 pods, ensuring all finalizers are removed before counting the Pod. ([#104666](https://github.com/kubernetes/kubernetes/pull/104666), [@alculquicondor](https://github.com/alculquicondor))

#### Other API changes:
- The beta feature `ServerSideApply` enables tracking and managing changed fields for all new objects, which means there will be `managedFields` in `metadata` with the list of managers and their owned fields.

* The Prometheus metrics for the kube-apiserver for tracking incoming API requests and latencies now return the `subresource` label for correctly attributing the type of API call. ([#46354](https://github.com/kubernetes/kubernetes/pull/46354), [@smarterclayton](https://github.com/smarterclayton))
