- kubeadm: added back `--cert-dir` option for `kubeadm init phase certs sa` ([#73239](https://github.com/kubernetes/kubernetes/pull/73239), [@mattkelly](https://github.com/mattkelly))
- kubeadm: now explicitly waits for `etcd` to have grown when joining a new control plane ([#72984](https://github.com/kubernetes/kubernetes/pull/72984), [@ereslibre](https://github.com/ereslibre))
