- A new /resize subresource was added to request pod resource resizing. Update your k8s client code to utilize the /resize subresource for Pod resizing operations.

New alpha features include:
* Online volume resizing will increase the filesystem size of a resized volume without requiring a Pod restart.

   * is {@code 60}, and the concurrency level is {@code 8}, then eight segments are created, each
   * having a hash table of size eight. Providing a large enough estimate at construction time
   * avoids the need for expensive resizing operations later, but setting this value unnecessarily
   * high wastes memory.
   *
   * @return this {@code CacheBuilder} instance (for chaining)
   * @throws IllegalArgumentException if {@code initialCapacity} is negative

* Improved messages user gets during and after volume resizing is done, providing a clear message to the user explaining what to do when resizing is finished. ([#58415](https://github.com/kubernetes/kubernetes/pull/58415), [@gnufied](https://github.com/gnufied))

* [alpha] Volume resizing

  * You can now increase the size of a volume by calling the Kubernetes API.

  * For alpha, this feature increases only the size of the underlying volume. It does not support resizing the file system.

  * For alpha, volume resizing supports only Gluster volumes.

* Deprecate deleting-pods-burst ControllerManager flag ([#28882](https://github.com/kubernetes/kubernetes/pull/28882), [@gmarek](https://github.com/gmarek))
* Add support for terminal resizing for exec, attach, and run. Note that for Docker, exec sessions ([#25273](https://github.com/kubernetes/kubernetes/pull/25273), [@ncdc](https://github.com/ncdc))

- Enabled completion for aliases defined in `kubectlrc`. ([#131586](https://github.com/kubernetes/kubernetes/pull/131586), [@ardaguclu](https://github.com/ardaguclu))

and enhances scheduling of pods that use CSI volumes with late binding.

[Volume expansion](https://github.com/kubernetes/enhancements/issues/284) adds support
for resizing existing persistent volumes.

### NonPreemptingPriority to Stable

This feature adds [a new option to PriorityClasses](https://github.com/kubernetes/enhancements/issues/902),

- In some cases, a Flex volume resize may leave a PVC with erroneous Resizing condition even after volume has been successfully expanded. Users may choose to delete the condition, but it is not required. ([#71470](https://github.com/kubernetes/kubernetes/issues/71470))
