Upstream has released v0.8.0 recently and we should ship it in OCP 4.7.
Upstream changelog: https://github.com/kubernetes-sigs/aws-ebs-csi-driver/blob/master/CHANGELOG-0.x.md The main change is support for gp3 volumes, which is even default when nothing is set in StorageClass. Our operator creates "gp2-csi" StorageClass with "type: gp2", so users should not see any change.
Did a regression test of aws ebs csi driver, all passed. Verified with: 4.7.0-0.nightly-2021-01-10-070949
