Changes by Kind

API Change

• VolumeGroupSnapshot, VolumeGroupSnapshotContent, and VolumeGroupSnapshotClass
  are now available in v1beta1 version. The support for the v1alpha1 version have been removed. (#1150, @leonardoce)

Other (Cleanup or Flake)

• Move the logic of creating individual VolumeSnapshot and VolumeSnapshotContent resources for dynamically created VolumeGroupSnapshot from csi-snapshotter sidecar to snapshot-controller. (#1171, @leonardoce)

Uncategorized

• The enable-volume-group-snapshots flag has been replaced by feature-gates flag.
  Enable feature gate to enable volumegroupsnapshot, i.e., --feature-gates=CSIVolumeGroupSnapshot=true.
  By default the feature gate is disabled (#1194, @yati1998)
• The validation webhook was deprecated in v8.0.0 and it is now removed.
  The validation webhook would prevent creating multiple default volume snapshot classes and multiple default volume group snapshot classes for the same CSI driver. With the removal of the validation webhook, an error will still be raised when dynamically provisioning a VolumeSnapshot or VolumeGroupSnapshot when multiple default volume snapshot classes or multiple default volume group snapshot classes for the same CSI driver exist. (#1186, @yati1998)
• Use v1.11.0 version of CSI spec (#1209, @yati1998)

Urgent Upgrade Notes

(No, really, you MUST read this before you upgrade)

• The validation webhook was deprecated in v8.0.0 and it is now removed.
  The validation webhook would prevent creating multiple default volume snapshot classes and multiple default volume group snapshot classes for the same CSI driver. With the removal of the validation webhook, an error will still be raised when dynamically provisioning a VolumeSnapshot or VolumeGroupSnapshot when multiple default volume snapshot classes or multiple default volume group snapshot classes for the same CSI driver exist. (#1186, @yati1998)

Changes by Kind

API Change

• Add a field called volumegroupsnapshotcontent.status.volumeSnapshotHandlePairList that allows the consumer to quickly map volume handles with snapshot handles. (#1169, @leonardoce)
• The volumegroupsnapshot.status.pvcVolumeSnapshotRefList field has been removed. VolumeShapshots members of a dynamically provisioned VolumeGroupSnapshot will have their persistentVolumeClaimName set, allowing the consumer to map the PVC being snapshotted with the corresponding snapshot. (#1200, @leonardoce)
• The volumegroupsnapshotcontent.status.pvVolumeSnapshotContentList field has been removed. The same information can be found in volumegroupsnapshotcontent.status.volumeSnapshotHandlePairList (#1199, @leonardoce)
• VolumeGroupSnapshotContent.status.creationTime is now a metav1.Time instead of an unix epoch time (#1235, @leonardoce)
• VolumeGroupSnapshot, VolumeGroupSnapshotContent, and VolumeGroupSnapshotClass
  are now available in v1beta1 version. The support for the v1alpha1 version have been removed. (#1150, @leonardoce)
