- Kubeadm: fix the bug that configurable KubernetesVersion not respected during kubeadm join ([#111021](https://github.com/kubernetes/kubernetes/pull/111021), [@SataQiu](https://github.com/SataQiu)) [SIG Cluster Lifecycle]

### Changed

- HA improvements:
  - `kubeadm join --experimental-control-plane` can now be used to join control plane instances to an existing cluster.
  - `kubeadm upgrade node experimental-control-plane` can now be used for upgrading secondary control plane instances created with `kubeadm join --experimental-control-plane`.
Multi-arch support (EXPERIMENTAL):

			if !endpoint.IsLocal {
				continue
			}

			server := &storageRESTServer{
				endpoint: endpoint,
			}

			subrouter := router.PathPrefix(path.Join(storageRESTPrefix, endpoint.Path)).Subrouter()

			subrouter.Methods(http.MethodPost).Path(storageRESTVersionPrefix + storageRESTMethodHealth).HandlerFunc(h(server.HealthHandler))

	}, {

			return strings.Join(ss, "")

- Kubeadm: fix a whitespace issue in the output of the "kubeadm join" command shown as the output of "kubeadm init" and "kubeadm token create --print-join-command" ([#97413](https://github.com/kubernetes/kubernetes/pull/97413), [@SataQiu](https://github.com/SataQiu)) [SIG Cluster Lifecycle]

- kubeadm: added the `WaitForAllControlPlaneComponents` feature gate. It could be used to tell kubeadm to wait for all control plane components to be ready when running "kubeadm init" or "kubeadm join --control-plane". Previously, kubeadm only waited for the kube-apiserver. The "kubeadm join" workflow now includes a new experimental phase called "wait-control-plane". This phase was marked as non-experimental when WaitForAllControlPlaneComponents became GA. Accordingly, a "kubeadm init" phase...

- Kubeadm: added `show-join-command` as a new separate phase at the end of `kubeadm init`. You can skip printing the join information by using `kubeadm init --skip-phases=show-join-command`. Executing only this phase on demand will throw an error because the phase needs dependencies such as bootstrap tokens to be pre-populated. ([#111512](https://git...

- Kubeadm: when adding new control plane nodes with "kubeadm join", ensure that the etcd member addition is performed only if a given member URL does not already exist in the list of members. Similarly, on "kubeadm reset" only remove an etcd member if its ID exists. ([#127621](https://github.com/kubernetes/kubernetes/pull/127621),...

- Kubeadm: unhide the "etcd-join" phase of "kubeadm join" to allow on-demand execution of the phase if the ControlPlaneLocalMode feature gate is not enabled ([#135481](https://github.com/kubernetes/kubernetes/pull/135481), [@borovetsav](https://github.com/borovetsav)) [SIG Cluster Lifecycle]...
