GA milestones hit

- [3756 - Robust VolumeManager Reconstruction](https://github.com/kubernetes/enhancements/issues/3756) moved to GA in v1.30. This feature improves Kubelet handling of mounted volumes across restarts, enabling faster, more robust recovery.
- [3141 - Prevent Unauthorized Volume Mode Conversion](https://github.com/kubernetes/enhancements/issues/3141) moved to GA in v1.30. This feature prevents unauthorized conversion of the volume mode when creating a Persistent Volume Claim from a Volume Snapshot.
- [3762 - Persistent Volume last phase transition time](https://github.com/kubernetes/enhancements/issues/3762) moved to GA in v1.31. This feature adds a PersistentVolumeStatus field which holds a timestamp of when a PersistentVolume last transitioned to a different phase. This allows you to measure time e.g. between a PV Pending and Bound. This can be also useful for providing metrics and SLOs.
- [1847 - Auto remove PVCs created by StatefulSet](https://github.com/kubernetes/enhancements/issues/1847) moved to GA in v1.32. This feature, co-owned with SIG-Apps, allows the PVCs created by StatefulSet to be automatically deleted when the volumes are no longer in use to ease management of StatefulSets that don't live indefinitely.

Successful progress

- [3751 - Kubernetes VolumeAttributesClass ModifyVolume](https://github.com/kubernetes/enhancements/issues/3751) moved to Beta in v1.31. This feature extends the Kubernetes Persistent Volume API to allow users to dynamically modify volume options (such as IOPs and throughput), after a volume is provisioned. (Note: The current status of this enhancement is marked as at risk for code freeze.)
- [1790 - Recover from Volume Expansion Failure](https://github.com/kubernetes/enhancements/issues/1790) moved to Beta in v1.32. This feature allows users to recover from volume expansion failure by retrying with a smaller size.
- [3476 - Volume Group Snapshot](https://github.com/kubernetes/enhancements/issues/3476) moved to Beta in v1.32. The feature introduces a VolumeGroupSnapshot API to take a snapshot of multiple volumes together.

2. Are there any areas and/or subprojects that your group needs help with (e.g. fewer than 2 active OWNERS)?

- Write more tests; monitor test grid health; work on test
framework out of tree; enhance CSI release tools.
- Doc writer to improve docs on CSI side and in general in
Storage side.
- We have a weekly issue triage meeting, but would apprecia
te help with more efficient issue triage and help with fixi
ng the issues.
