- Kubeadm: Fixed a preflight check that could fail hostname construction in IPv6 setups. ([#134588](https://github.com/kubernetes/kubernetes/pull/134588), [@liggitt](https://github.com/liggitt)) [SIG API Machinery, Auth, Cloud Provider, Cluster Lifecycle and Testing]

* Fix bug that caused `kubectl` commands to sometimes fail to refresh access token when running against GKE clusters. ([#66314](https://github.com/kubernetes/kubernetes/pull/66314), [@jlowdermilk](https://github.com/jlowdermilk))

Kubeadm: during "init" an empty cgroupDriver value in the KubeletConfiguration is now always set to "systemd" unless the user is explicit about it. This requires existing machine setups to configure the container runtime to use the "systemd" driver. Documentation on this topic can be found here: https://kubernetes.io/docs/setup/production-environment/container-runtimes/. When upgrading existing clusters / nodes using "kubeadm upgrade" the old cgroupDriver value is preserved, but in 1.22 this change will...

- Kubernetes components no longer handle panics, and instead actively crash.  All Kubernetes components should be run by something that actively restarts them. This is true of the default setups, but those with custom environments may need to double-check (#28800, @lavalamp)
- kubelet now defaults to `--cloud-provider=auto-detect`, use `--cloud-provider=''` to preserve previous default of no cloud provider (#28258, @vishh)
