 - CSI migration of AWS EBS volumes requires AWS EBS CSI driver ver. 1.0 that supports `allowAutoIOPSPerGBIncrease` parameter in StorageClass. ([#101082](https://github.com/kubernetes/kubernetes/pull/101082), [@jsafrane](https://github.com/jsafrane))

  much later). ([#122756](https://github.com/kubernetes/kubernetes/pull/122756), [@hakman](https://github.com/hakman)) [SIG Network]
- If a pvc has an empty storageClassName, persistentvolume controller won't try to assign a default StorageClass ([#122704](https://github.com/kubernetes/kubernetes/pull/122704), [@carlory](https://github.com/carlory)) [SIG Apps and Storage]

    ```
    Storage class spec:
    kind: StorageClass
    apiVersion: storage.k8s.io/v1
    metadata:
      name: fastpolicy1
    provisioner: kubernetes.io/vsphere-volume
    parameters:
        diskformat: zeroedthick

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