- Fixed a race condition that could result in erroneous volume unmounts for flex volume plugins during kubelet restart. ([#127669](https://github.com/kubernetes/kubernetes/pull/127669), [@olyazavr](https://github.com/olyazavr))

  
  It matches all PVC objects that have the volume attributes class mentioned. 
  

### Bug or Regression

- Added support for Pods to reference the same `PersistentVolumeClaim` across multiple volumes. ([#122140](https://github.com/kubernetes/kubernetes/pull/122140), [@huww98](https://github.com/huww98)) [SIG Node, Storage and Testing]

- Enabled kube-apiserver support for `PodCertificateRequest` and `PodCertificate` projected volumes (behind the `PodCertificateRequest` feature gate).
