### Cluster Lifecycle

  also supported using "kubeadm alpha certs renew", but not switching between the RSA and
  ECDSA algorithms on the fly or during upgrades. ([#86953](https://github.com/kubernetes/kubernetes/pull/86953), [@rojkov](https://github.com/rojkov)) [SIG API Machinery, Auth and Cluster Lifecycle]

- NodeLifecycleController: Now node lease renewal is treated as the heartbeat signal from the node, in addition to NodeStatus Update. ([#69241](https://github.com/kubernetes/kubernetes/pull/69241), [@wangzhen127](https://github.com/wangzhen127))

on a node host or move it to a safe location. `kubadm certs renew` will renew the certificate in `super-admin.conf` to one year if the file exists; if it does not exist a "MISSING" note will be printed. `kubeadm upgrade apply` for this release will migrate this particular node to the two file setup. Subsequent kubeadm releases will continue to optionally renew the certificate in `super-admin.conf` if the file exists on disk and if renew on upgrade is not disabled. `kubeadm join --control-plane` will...
