- '`kubeadm`: added validation to verify that the `CertificateKey` is a valid hex
  encoded AES key.' ([#120064](https://github.com/kubernetes/kubernetes/pull/120064), [@SataQiu](https://github.com/SataQiu))
- A customizable `OrderedScoreFuncs()` function was introduced. Out-of-tree plugins 

* ACTION REQUIRED: kubeadm: the mixture of "--config" and "--certificate-key" is no longer allowed. The InitConfiguration and JoinConfiguration objects now support the "certificateKey" field and this field should be used instead of the command line argument in case a configuration file is already passed. ([#78542](https://github.com/kubernetes/kubernetes/pull/78542), [@neolit123](https://github.com/neolit123))
