- Kubeadm: enabled the v1beta4 API. For a complete changelog since v1beta3 please see https://kubernetes.io/docs/reference/config-api/kubeadm-config.v1beta4/.

  - The "extraArgs" component construct is now a list of "name"/"value" pairs instead of a string/string map. This has been done to support duplicate args where needed.
