  - `v1alpha1` has been removed.
  - `v1alpha3` has split apart `MasterConfiguration` into separate components; `InitConfiguration`, `ClusterConfiguration`, `JoinConfiguration`, `KubeletConfiguration`, and `KubeProxyConfiguration`
  - Different configuration types can be supplied all in the same file separated by `---`.
- Improved CRI handling
  - crictl is no longer required in docker-only setups.
