- `CSINodeExpandSecret` feature has been promoted to `GA` in this release and is enabled
  by default. The CSI drivers can make use of the `secretRef` values passed in `NodeExpansion`
  request optionally sent by the CSI Client from this release onwards. ([#121303](https://github.com/kubernetes/kubernetes/pull/121303), [@humblec](https://github.com/humblec))

    * validate the name of the ConfigMap in a ConfigMapRef
    * validate the name of the Secret in a SecretRef

  * Fix the bug where StartedAt time is not reported for exited containers. ([#45977](https://github.com/kubernetes/kubernetes/pull/45977), [@yujuhong](https://github.com/yujuhong))

* Changes/deprecations
