 ⚠️ See the [update instructions](https://github.com/cloudscale-ch/csi-cloudscale#from-csi-cloudscale-v3x-to-v4x).
 
 **Breaking change:** This release **requires** Kubernetes VolumeSnapshot CRDs and the external snapshot controller to be installed **before** installing or upgrading this driver. Clusters without these components must install them first. Otherwise, snapshot-related operations and the snapshot resource in the Helm chart will fail to work.
 
 * Add CSI snapshot support, including create, delete, list, and creating volumes from snapshots.
 * Add `VolumeSnapshotClass` and other snapshot-related resources to the Helm chart and examples. When using Helm, snapshot classes are now created from the `csi.snapshotClasses` configuration.
 * Cleaned up RBAC rules in Helm chart.
+* Prevent silent volume migration in ControllerPublishVolume.
 * Update `github.com/cloudscale-ch/cloudscale-go-sdk` fron `v6.0.1` to `v7.0.0`.
-* Bump `google.golang.org/grpc` from `v1.77.0` to `v1.79.1`.
 * Bump `github.com/sirupsen/logrus` from `v1.9.3` to `v1.9.4`.
-* Bump `golang.org/x/sys` from `v0.39.0` to `v0.41.0`.
+* Bump `google.golang.org/grpc` from `v1.77.0` to `v1.79.3`.
+* Bump `golang.org/x/sys` from `v0.39.0` to `v0.42.0`.
+* Bump `golang.org/x/oauth2` from `v0.35.0` to `v0.36.0`.
