The PVC service on Kubernetes Pod hosts details now show the VolumeAttributesClass name in Kubernetes 1.29+ (with the feature gate enabled) and 1.34+ (by default). This Kubernetes feature allows PersistentVolumeClaims (PVCs) to have an associated VolumeAttributesClass, which enables mutable configuration of certain storage class properties. The exact behavior depends on the Container Storage Interface (CSI) driver in use.

More information about this Kubernetes feature can be found in the upstream documentation.

This change is purely informational and does not require any configuration changes or affect existing workflows.

No user interaction is needed; the information will automatically appear in the service details when provided by Kubernetes.
