- 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

- kubeadm: increased the verbosity of API client dry-run actions during the subcommands "init", "join", "upgrade" and "reset". It also allowed dry-run on 'kubeadm join' even if there was no existing cluster by utilizing a faked, in-memory cluster-info ConfigMap. ([#126776](https://github.com/kubernetes/kubernetes/pull/126776), [@neolit123](https://github.com/neolit123))

- 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):

- 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...
