#### Volume Plugins
* [stable] Volume plugin for StorageOS provides highly-available cluster-wide persistent volumes from local or attached node storage. See [Persistent Volumes - StorageOS](https://kubernetes.io/docs/concepts/storage/persistent-volumes/#storageos) and [Storage Volumes - StorageOS](https://kubernetes.io/docs/concepts/storage/volumes/#storageos).

### Promoted Local Ephemeral Storage Capacity Isolation to Stable

	if len(storageos.VolumeName) == 0 {
		allErrs = append(allErrs, field.Required(fldPath.Child("volumeName"), ""))

	if len(storageos.VolumeNamespace) > 0 {

### Storage

[SIG Storage](https://github.com/kubernetes/community/tree/master/sig-storage) is responsible for storage and volume plugin components.

- Fix azure file migration issue ([#97877](https://github.com/kubernetes/kubernetes/pull/97877), [@andyzhangx](https://github.com/andyzhangx)) [SIG Auth, Cloud Provider and Storage]
- Fix to recover CSI volumes from certain dangling attachments ([#96617](https://github.com/kubernetes/kubernetes/pull/96617), [@yuga711](https://github.com/yuga711)) [SIG Apps and Storage]

- `storageos`,`quobyte` and `flocker` storage volume plugins are deprecated and will be removed in a later release. ([#101773](https://github.com/kubernetes/kubernetes/pull/101773), [@Jiawei0227](https://github.com/Jiawei0227)) [SIG Storage]

### API Change

- [`KT-61348`](https://youtrack.jetbrains.com/issue/KT-61348) K2: Refactor FIR2IR declaration storages
- [`KT-54905`](https://youtrack.jetbrains.com/issue/KT-54905) KLIB check on compiled with pre-release version
- [`KT-61249`](https://youtrack.jetbrains.com/issue/KT-61249) Move fir-related code from backend.native module

* StorageOS Volume Driver ([#42156](https://github.com/kubernetes/kubernetes/pull/42156), [@croomes](https://github.com/croomes))
    * [StorageOS](http://www.storageos.com) can be used as a storage provider for Kubernetes.  With StorageOS, capacity from local or attached storage is pooled across the cluster, providing converged infrastructure for cloud-native applications.

- Changed feature CSIMigrationAWS to on by default. This feature requires the AWS EBS CSI driver to be installed. (#106098, @wongma7) [SIG Storage]
- Ensures that volume is deleted from the storage backend when the user tries to delete the PV object manually and the PV ReclaimPolicy is Delete. (#105773, @deepakkinni) [SIG Apps and Storage]
