### CSI Volume Snapshot graduates to General Availability

CSI Volume Snapshot moves to GA in the 1.20 release. This feature provides a standard way to trigger volume snapshot operations in Kubernetes and allows Kubernetes users to incorporate snapshot operations in a portable manner on any Kubernetes environment regardless of supporting underlying storage providers.

		return np, grid.NewRemoteErr(errServerNotInitialized)

	pools, ok := objAPI.(*erasureServerPools)
	if !ok {
		return
	}

	// No need to return errors, this is not a highly strict operation.
	uploadID := mss.Get(peerRESTUploadID)
	if uploadID != "" {
		pools.ClearUploadID(uploadID)
	}

	return
}

containers are only an alpha feature. To allow using CSI storage on Windows nodes, [CSIProxy](https://github.com/kubernetes-csi/csi-proxy) enables CSI node plugins to be deployed as unprivileged pods, using the proxy to perform privileged storage operations on the node.

Another feature moving to GA in v1.22 is CSI Service Account Token support. This feature allows CSI drivers to use pods' [bound service account tokens](https://kubernetes.io/docs/reference/access-authn-authz/service-ac...

- Kubeadm: fixed the bug where the v1beta4 Timeouts.EtcdAPICall field was not respected in etcd client operations, and the default timeout of 2 minutes was always used.

### Other (Cleanup or Flake)

  a bug in the transforming informer during the Resync operation, 
  by making the transforming function idempotent. ([#124352](https://github.com/kubernetes/kubernetes/pull/124352), [@wojtek-t](https://github.com/wojtek-t)) [SIG API Machinery and Scheduling]

### Storage capacity tracking

- Support more than 100 disk mounts on Windows ([#105673](https://github.com/kubernetes/kubernetes/pull/105673), [@andyzhangx](https://github.com/andyzhangx))
- Support using negative array index in JSON patch replace operations. ([#105896](https://github.com/kubernetes/kubernetes/pull/105896), [@zqzten](https://github.com/zqzten))
