* Bugfix: csi plugin supporting raw block that does not need attach mounted failed ([#79920](https://github.com/kubernetes/kubernetes/pull/79920), [@cwdsuzhou](https://github.com/cwdsuzhou))

* Fixed CSI gRPC connection leak during volume operations. ([#64519](https://github.com/kubernetes/kubernetes/pull/64519), [@vladimirvivien](https://github.com/vladimirvivien))
* Fixed error reporting of CSI volumes attachment. ([#63303](https://github.com/kubernetes/kubernetes/pull/63303), [@jsafrane](https://github.com/jsafrane))

- Fixed an issue where a CSI migrated volume may be prematurely detached when the CSI driver is not running on the node.

- The in-tree cloud provider for vSphere has been deprecated and removed. Users are advised to utilize the external cloud provider and CSI driver available at https://github.com/kubernetes/cloud-provider-vsphere. ([#122937](htt...

- Remove check for CSI driver running on node for CSI migration ([#115772](https://github.com/kubernetes/kubernetes/pull/115772), [@sunnylovestiramisu](https://github.com/sunnylovestiramisu)) [SIG Apps and Storage]

 - Deprecated support for CSI migration of `Ceph RBD volumes`. Users who were relying on Kubernetes' ability

For the 1.9 release, SIG Storage made Kubernetes more pluggable and modular by introducing an alpha implementation of the Container Storage Interface (CSI). CSI will make installing new volume plugins as easy as deploying a pod, and enable third-party storage providers to develop their plugins without the need to add code to the core Kubernetes codebase.
