- 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.

- New metric `kubelet_pleg_last_seen_seconds` to aid diagnosis of PLEG not healthy issues. ([#86251](https://github.com/kubernetes/kubernetes/pull/86251), [@bboreham](https://github.com/bboreham)) [SIG Node]

* A new flag "progress-report-url" has been added to the test context which allows progress information about the test run to be sent to a webhook. In addition, this information is printed to stdout to aid in users watching the logs. ([#84524](https://github.com/kubernetes/kubernetes/pull/84524), [@johnSchnake](https://github.com/johnSchnake))

- Fix kubelet to properly log when a container is started. Before, sometimes the log said that a container is dead and was restarted when it was started for the first time. This only happened when using pods with initContainers and regular containers. ([#91469](https://github.com/kubernetes/kubernetes/pull/91469), [@rata](https://github.com/rata))...
