This enhancement +helps Kubernetes users understand when a [PersistentVolume](/docs/concepts/storage/persistent-volumes/) transitions between +different phases, allowing for more efficient and informed resource management. + +With this feature enabled, every PersistentVolume object will have a new field `.status.lastTransitionTime`, that holds a timestamp of +when the volume last transitioned its phase. This change is not immediate; the new field will be populated whenever a PersistentVolume +is updated and first transitions between phases (`Pending`, `Bound`, or `Released`) after upgrading to Kubernetes v1.31. + +## What changed? + +The API strategy for updating PersistentVolume objects has been modified to populate the `.status.lastTransitionTime` field with the +current timestamp whenever a PersistentVolume transitions phases. Users are allowed to set this field manually if needed, but it will +be overwritten when the PersistentVolume transitions phases again. + +For more details, read about +[Phase transition timestamp](/docs/concepts/storage/persistent-volumes/#phase-transition-timestamp) in the Kubernetes documentation. +You can also read the previous [blog post](/blog/2023/10/23/pv-last-phase-transtition-time) announcing the feature as alpha in v1.28. + +To provide feedback, join our [Kubernetes Storage Special-Interest-Group](https://github.com/kubernetes/community/tree/master/sig-storage) (SIG) +or participate in discussions on our [public Slack channel](https://app.slack.com/client/T09NY5SBT/C09QZFCE5).
