* Docker versions 1.10.3 - 1.12.3
  * Docker version 1.11.2 known issues

* Include serial port output in GCP log-dump ([#37248](https://github.com/kubernetes/kubernetes/pull/37248), [@mtaufen](https://github.com/mtaufen))
* Collect installation and configuration service logs for tests ([#37401](https://github.com/kubernetes/kubernetes/pull/37401), [@mtaufen](https://github.com/mtaufen))
