### Bug or Regression

- Fix a bug where kube-apiserver could emit an further watch even even if decryption failed for earlier event and it was not emitted. ([#131159](https://github.com/kubernetes/kubernetes/pull/131159), [@wojtek-t](https://github.com/wojtek-t)) [SIG API Machinery and Etcd]

- kubeadm now includes the ability to specify certificate encryption and decryption keys for the upload and download certificate phases as part of the new v1beta2 kubeadm config format. ([#77012](https://github.com/kubernetes/kubernetes/pull/77012), [@rosti](https://github.com/rosti))
