* Default value for expendable pod priority cutoff in GCP deployment of Cluster Autoscaler changed from 0 to -10.
    * action required: users deploying workloads with priority lower than 0 may want to use priority lower than -10 to avoid triggering scale-up.
* [action required] kubeadm: The `v1alpha1` config API has been removed. ([#65628](https://github.com/kubernetes/kubernetes/pull/65628), [@luxas](https://github.com/luxas))

The reason why `ESSingleNodeTestCase` exists is that all our components used to
be very hard to set up in isolation, which had led us to having a number of
integration tests but close to no unit tests. `ESSingleNodeTestCase` is a
workaround for this issue which provides an easy way to spin up a node and get
access to components that are hard to instantiate like `IndicesService`.
