### Generic Ephemeral Volumes

* [stable] You can now customize the iSCSI initiator name per volume in the iSCSI volume plugin.

* [stable] You can now specify the World Wide Identifier (WWID) for the volume identifier in the Fibre Channel volume plugin.

* [beta] Reclaim policy in StorageClass

  * You can now configure the reclaim policy in StorageClass, instead of defaulting to `delete` for dynamically provisioned volumes.

* [alpha] Volume resizing

the in-tree storage drivers indicate support for the `MetricsProvider` interface, but fail to configure this for BlockMode volumes. With a recent change, `Kubelet` will call `GetMetrics()` for BlockMode volumes, and the in-tree drivers that miss the support cause a Go panic. Now the in-tree storage drivers that support BlockMode volumes, will return the Capacity of the volume in the `GetMetrics()` call.

- 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))

- Add e2e test to node expand volume with secret ([#115451](https://github.com/kubernetes/kubernetes/pull/115451), [@zhucan](https://github.com/zhucan)) [SIG Storage and Testing]

- Fixed attaching volumes after detach errors. Now volumes that failed to detach are not treated as attached. Kubernetes will make sure they are fully attached before they can be used by pods.

### Promoted CSI Ephemeral Volume to Stable

- It introduces a new scope name `VolumeAttributesClass`. 
  
  It matches all PVC objects that have the volume attributes class mentioned.
