 // Package v1beta1 defines the v1beta1 version of the kubeadm config file format.
 // This version graduates the kubeadm config to BETA and is a big step towards GA.
 //
-// A list of changes since v1alpha3:
-// - "apiServerEndpoint" in InitConfiguration was renamed to "localAPIServerEndpoint" for better clarity of what the field
-// represents.
-// - Common fields in ClusterConfiguration such as "*extraArgs" and "*extraVolumes" for control plane components are now moved
-// under component structs - i.e. "apiServer", "controllerManager", "scheduler".
-// - "auditPolicy" was removed from ClusterConfiguration. Please use "extraArgs" in "apiServer" to configure this feature instead.
-// - "unifiedControlPlaneImage" in ClusterConfiguration was changed to a boolean field called "useHyperKubeImage".
-// - ClusterConfiguration now has a "dns" field which can be used to select and configure the cluster DNS addon.
-// - Both "localEtcd" and "dns" configurations now support custom image repositories.
-// - the "controlPlane*" related fields in JoinConfiguration were refactored into a sub structure.
-// - "clusterName" was removed from JoinConfiguration and the name is now fetched from the existing cluster.
