- If `kubeadm reset` finds no etcd member ID for the peer it removes during the `remove-etcd-member` phase, it continues immediately to other phases, instead of retrying the phase for up to 3 minutes before continuing. ([#117948](https://github.com/kubernetes/kubernetes/pull/117948),...

- Fixed the discoverability of `apiregistration.k8s.io` in `openapi/v3` ([#118879](https://github.com/kubernetes/kubernetes/pull/118879), [@atiratree](https://github.com/atiratree))

- kubeadm: Added better handling of errors during unmount when calling `kubeadm reset`. When failing to unmount directories under `/var/run/kubelet`, kubeadm will now throw an error instead of showing a warning and continuing to clean up said directory. In such situations, it is better for you to inspect the problem and resolve it manually. Then, you can call `kubeadm reset` again to complete the cleanup.

### Bug or Regression

- '`kubeadm`: printing the default component configs for `reset` and `join` is now

- '`kubeadm`: removed `system:masters` organization from `etcd/healthcheck-client`
