* Protobuf serialization does not distinguish between `[]` and `null`.

* Fixes a hang on kubelet startup when using systemd cgroup driver of libcontainer. ([#61926](https://github.com/kubernetes/kubernetes/pull/61926), [@filbranden](https://github.com/filbranden))
* Prevent 1.10 e2es testing deprecated CAdvisorPort in v1.11 ([#64184](https://github.com/kubernetes/kubernetes/pull/64184), [@dixudx](https://github.com/dixudx))

### SIG OpenStack

SIG-OpenStack continued to build out testing, with eleven acceptance tests covering a wide-range of scenarios and use-cases. During the 1.11 cycle our reporting back to test-grid has qualified the OpenStack cloud provider as a gating job for the Kubernetes release.

#### **Cloud Provider Integration**

*   Added `cloud-controller-manager` to `hyperkube`. This is useful as a number of deployment tools run all of the kubernetes components from the `hyperkube `image/binary. It also makes testing easier as a single binary/image can be built and pushed quickly.
