Kubernetes v1.37: Tracking When a PersistentVolumeClaim Was Last Used (Beta)

Kubernetes v1.37 enables the PersistentVolumeClaimUnusedSinceTime feature by default, adding an Unused condition to PVC status. This native tracking helps administrators identify orphaned volumes without custom scripts. The update simplifies storage cleanup in large clusters, reducing manual cross-referencing of pods and volumes to manage cloud costs effectively.
