- Fix: After a Node is down and take some time to get back to up again, the mount point of the evicted Pods cannot be cleaned up successfully. (#111933) Meanwhile Kubelet will print the log `Orphaned pod "xxx" found, but error not a directory occurred when trying to remove the volumes dir` every 2 seconds.

- Implemented alpha support for a drop-in kubelet configuration directory. ([#119390](https://github.com/kubernetes/kubernetes/pull/119390), [@sohankunkerkar](https://github.com/sohankunkerkar))

* Kubelets using TLS bootstrapping (`--bootstrap-kubeconfig`) or certificate rotation (`--rotate-certificates`) store certificates in the directory specified by `--cert-dir`. The default location (`/var/run/kubernetes`) is automatically erased on reboot on some platforms, which can prevent the kubelet from authenticating to the API server after a reboot. Specifying a non-transient location,...

- kubelet allowed specifying a custom root directory for pod logs (instead of the default /var/log/pods) using the `podLogsDir` key in kubelet configuration.

- Kubeadm will cleanup the stale data on best effort basis. Stale data will be removed when each reset phase are executed, default etcd data directory will be cleanup when the `remove-etcd-member` phase are executed.

- Volume attach or publish operation will not fail at `kubelet` if target path directory already exists on the node. ([#119735](https://github.com/kubernetes/kubernetes/pull/119735), [@akankshapanse](https://github.com/akankshapanse))
