**Note** Starting with this minor version release, the snapshot API is upgraded from `v1beta1` to `v1`. Invalid `v1beta1` snapshots upgraded to `v1` may not be usable anymore.

Cluster upgrades attempted through the cloud control panel will cause [clusterlint](https://docs.digitalocean.com/support/clusterlint-error-fixes/index.html.md) to scan for invalid snapshots and prevent upgrades accordingly. For more information on how to correct invalid snapshots, see [Invalid CSI Volume Snapshots](https://docs.digitalocean.com/support/clusterlint-error-fixes/index.html.md#invalid-csi-volume-snapshots).
