- The SnapshotMetadataService CRD used to advertise the CSI Driver's support for the CSI Changed Block Tracking feature.
- gRPC stubs
- Examples
- Instructions on how to deploy a CSI driver with the

- A snapshot-metadata-verifier command to provide a way to verify allocated or changed blocks metadata generated by CSI Drivers.
- Instructions on how to deploy a CSI driver with the
