### CSI Service Account Token

- In-Place Update of Pod Resources (alpha feature) - resizing of pod may race with other pod updates. ([#116826](https://github.com/kubernetes/kubernetes/issues/116826) [SIG Node])

### Other (Cleanup or Flake)

In-tree bug fixes and improvements included:
- Fix load balancer status without VIP.
- Fix filtering of server status.
- Fix resizing PVC of Cinder volume.
- Disable load balancer configuration if it is not defined in cloud config.
- Add support for node shutdown taint.

- 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))

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),

- **Volume Extension**: There are quite a few enhancements in this release that pertain to volumes and volume modifications. Volume resizing support in CSI specs is moving to beta which allows for any CSI spec volume plugin to be resizable.
