# VAST CSI Driver 2.7.1 Release Notes

VAST CSI Driver 2.7.1 has been released in October 2026. This release includes:

## Enhancements

- VCSI-679: Added an ability to set the NFS protocol version that the driver uses when handling deletions on a VAST cluster with Trash Folder Access disabled. To do so, specify the `deletionMountOptions` option in the storage class definition (together with `deletionVipPool` and `deletionViewPolicy`). For example:
  - To use NFSv3:  

deletionViewPolicy: <view deletions="" data-tomark-pass=""><br>
deletionVipPool: <virtual deletions="" data-tomark-pass=""><br>
deletionMountOptions: vers=3</virtual></view>
  - To use NFSv4:  

deletionViewPolicy: <view deletions="" data-tomark-pass=""><br>
deletionVipPool: <virtual deletions="" data-tomark-pass=""><br>
deletionMountOptions: &quot;vers=4.2,proto=tcp&quot;<br>
If the <code data-backticks="1">deletionMountOptions</code> option is not specified, the driver uses NFSv3 for legacy local-mount deletions.</virtual></view>
- Operator: `kube-rbac-proxy sidecar` moved from `docker.io/kubebuilder/kube-rbac-proxy` to `quay.io/brancz/kube-rbac-proxy` (digest-pinned). Air-gap must mirror the new image.
- VastExtensions gRPC requires TLS on TCP and Unix. Charts generate a self-signed serving certificate and reuse it on upgrade.
- Extensions manager image ships the `vcsi` CLI at `/usr/local/bin/vcsi`.

## Resolved Issues

- VCSI-676: Resolved an issue that could cause an upgrade from 2.6.5-HF6, 2.6.5-HF7, 2.6.5-HF8 to 2.7.0 to fail due to volume name format discrepancy in manually created storage classes.
- VCSI-662: Eliminated a potential VAST CSI conroller memory leak that could occur when running with `verifySsl=false` in the driver's Helm chart.
