### Federation
* The --dns-provider argument of 'kubefed init' is now mandatory and does not default to `google-clouddns`. To initialize a Federation control plane with Google Cloud DNS, use the following invocation: 'kubefed init --dns-provider=google-clouddns' ([#42092](https://github.com/kubernetes/kubernetes/pull/42092), [@marun](https://github.com/marun))

 - Conformance image is now built with Distroless.

Invoking `ginkgo` and `e2e.test` are still supported through overriding entrypoint (docker) or defining container `spec.command` (kubernetes). ([#9...
