### Bug or Regression

- An issues preventing volume expand controller to annotate the PVC with `volume.kubernetes.io/storage-resizer` when the PVC StorageClass is already updated to the out-of-tree provisioner is now fixed.

 - 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))
