Changes since v21.07.0

- Kubernetes: Fixed issue where a pod could get stuck in Terminating state (Issue #572).
- Kubernetes: Fixed the case where an ONTAP-SAN-Economy FlexVol may be full of snapshot LUNs (Issue #533).
- Kubernetes: Fixed custom YAML installer issue with different image (Issue #613).
- Kubernetes: Fixed snapshot size calculation (Issue #611).
- Kubernetes: Fixed issue where all Trident installers could identify plain Kubernetes as OpenShift (Issue #639).
- Kubernetes: Fixed the Trident operator to stop reconciliation if the Kubernetes API server is unreachable (Issue #599).
