`--token-ttl 0` to `kubeadm init`. The default token can later be deleted with
 `kubeadm token delete`.

 - `kubeadm join` now delegates TLS Bootstrapping to the kubelet itself, instead
 of reimplementing the process. `kubeadm join` writes the bootstrap kubeconfig
 file to `/etc/kubernetes/bootstrap-kubelet.conf`.

- Fallback from OpenAPI V3 to V2 when the OpenAPI V3 document is invalid or incomplete. ([#117980](https://github.com/kubernetes/kubernetes/pull/117980), [@seans3](https://github.com/seans3)) [SIG CLI]
- Fix bug where `listOfStrings.join()` in CEL expressions resulted in an unexpected internal error. ([#117596](https://github.com/kubernetes/kubernetes/pull/117596), [@jpbetz](https://github.com/jpbetz)) [SIG API Machinery]

- 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...
