## Urgent Upgrade Notes 

### (No, really, you MUST read this before you upgrade)

- Deprecated beta APIs scheduled for removal in `v1.26` are no longer served. See https://kubernetes.io/docs/reference/using-api/deprecation-guide/#v1-26 for more information. ([#111973](https://github.com/kubernetes/kubernetes/pull/111973), [@liggitt](https://github.com/liggitt))

- Kubeadm: deprecate the "kubeadm alpha kubelet config enable-dynamic" command. To continue using the feature please defer to the guide for "Dynamic Kubelet Configuration" at k8s.io.
