- kubeadm: InitConfiguration now consists of two structs: InitConfiguration and ClusterConfiguration ([#67441](https://github.com/kubernetes/kubernetes/pull/67441), [@rosti](https://github.com/rosti))

- You can now use kubeadm's `InitConfiguration` and `JoinConfiguration` to define which preflight errors will be ignored. ([#75499](https://github.com/kubernetes/kubernetes/pull/75499), [@marccarre](https://github.com/marccarre))

- Kubeadm: add a new field `skipPhases` to `v1beta3` `InitConfiguration` and `JoinConfiguration` that can contain a list of phases to skip during "kubeadm init" and "kubeadm join". The flag "--skip-phases" takes precedence over this field. ([#101923](https://github.com/kubernetes/kubernetes/pull/101923), [@neoli...

- kubeadm: make the command "kubeadm alpha kubeconfig user" accept a "--config" flag and remove the following flags:
  - apiserver-advertise-address / apiserver-bind-port: use either localAPIEndpoint from InitConfiguration or controlPlaneEndpoint from ClusterConfiguration.
  - cluster-name: use clusterName from ClusterConfiguration

* kubeadm: UnifiedControlPlaneImage is replaced by UseHyperKubeImage boolean value. ([#70793](https://github.com/kubernetes/kubernetes/pull/70793), [@rosti](https://github.com/rosti))
* kubeadm v1beta1 API: InitConfiguration.APIEndpoint has been renamed to .LocalAPIEndpoint ([#70761](https://github.com/kubernetes/kubernetes/pull/70761), [@luxas](https://github.com/luxas))
