- Removed leading zeros from the etcd member ID in kubeadm log messages. ([#117919](https://github.com/kubernetes/kubernetes/pull/117919), [@dlipovetsky](https://github.com/dlipovetsky)) [SIG Cluster Lifecycle]

* Added xfsprogs to hyperkube container image. ([#56937](https://github.com/kubernetes/kubernetes/pull/56937), [@redbaron](https://github.com/redbaron))

* Improved messages user gets during and after volume resizing is done, providing a clear message to the user explaining what to do when resizing is finished. ([#58415](https://github.com/kubernetes/kubernetes/pull/58415), [@gnufied](https://github.com/gnufied))

- Kubeadm: when a subcommand is needed but not provided for a kubeadm command, print a help screen instead of showing a short message. ([#111277](https://github.com/kubernetes/kubernetes/pull/111277), [@chymy](https://github.com/chymy)) [SIG Cluster Lifecycle]

    * Some refactoring of error/status messages and functions to align with new approach.
