v1.6.0

Deprecation Notice

The Kubernetes 1.18 variant, aws-k8s-1.18, will lose support in March 2022. Kubernetes 1.18 is no longer receiving support upstream. We recommend replacing aws-k8s-1.18 nodes with a later variant, preferably aws-k8s-1.21 if your cluster supports it. See this issue for more details.
