Major features for stateful applications include automated updates to StatefulSets, enhanced updates for DaemonSets, a burst mode for faster StatefulSets scaling, and (alpha) support for local storage.

- Reduce default NodeStatusReportFrequency to 5 minutes. With this change, periodic node status updates will be send every 5m if node status doesn't change (otherwise they are still send with 10s).

  Bump NodeProblemDetector version to v0.8.0 to reduce forced NodeStatus updates frequency to 5 minutes. ([#84007](https://github.com/kubernetes/kubernetes/pull/84007), [@wojtek-t](https://github.com/wojtek-t))

### SIG Multicluster

### SIG API Machinery

This release SIG API Machinery focused mainly on CustomResources. For example, subresources for CustomResources are now beta and enabled by default. With this, updates to the `/status` subresource will disallow updates to all fields other than `.status` (not just `.spec` and `.metadata` as before). Also, `required` and `description` can be used at the root of the CRD OpenAPI validation schema when the `/status` subresource is enabled.

- New flag `--endpointslice-updates-batch-period` in kube-controller-manager can be used to reduce the number of endpointslice updates generated by pod changes.

  This allows the scheduler to handle cluster events faster with less memory.

  Specific node events include updates to taints, tolerations or allocatable.
  In-tree plugins now ignore node updates that don't modify any of these fields. ([#127220](https://github.com/kubernetes/kubernetes/pull/127220), [@sanposhiho](https://github.com/sanposhiho)) [SIG Node, Scheduling and Storage]
