`GenericEphemeralVolume` feature gate, provide a more flexible alternative to `EmptyDir` volumes: as with `EmptyDir`, volumes are created and deleted for each pod automatically by Kubernetes. But because the normal provisioning process is used (`PersistentVolumeClaim`), storage can be provided by third-party storage vendors and all of the usual volume features work. Volumes don't need to be empt; for example, restoring from snapshot is supported. ([#92784](https://github.com/kubernetes/kubernetes/pull/92784),...

* PersistentVolumes that are bound to a PersistentVolumeClaim will not be deleted. ([#58743](https://github.com/kubernetes/kubernetes/pull/58743), [@NickrenREN](https://github.com/NickrenREN))

* PersistentVolumeClaim metrics like "volume_stats_inodes" and "volume_stats_capacity_bytes" are now reported via kubelet prometheus ([#51553](https://github.com/kubernetes/kubernetes/pull/51553), [@wongma7](https://github.com/wongma7))

- A PersistentVolumeClaim may not have been synced to the controller local cache in time if the PersistentVolumeis bound by an external PV binder (such as kube-scheduler), so Kubernetes will now double check if PVC is not found in order to prevent the volume from being...

- The kube-scheduler added support for scheduling hints for the PersistentVolumeClaim resource within the VolumeBinding plugin.
