  - [alpha] Introducing the v1alpha1 CRI API to allow pluggable container runtimes; an experimental docker-CRI integration is ready for testing and feedback. ([docs](https://github.com/kubernetes/community/blob/master/contributors/devel/sig-node/container-runtime-interface.md)) ([kubernetes/features#54](https://github.com/kubernetes/enhancements/issues/54))

    * Discussion for these changes can be found on SIG Build's [TensorFlow Community Forum thread](https://discuss.tensorflow.org/t/tensorflow-linux-wheels-are-being-upgraded-to-manylinux2014/8339)

This allows the CRI runtime developers to verify that their runtime conforms to CRI, without needing to set up Kubernetes components or run Kubernetes end-to-end tests. ([docs](https://github.com/kubernetes/community/blob/master/contributors/devel/sig-node/cri-validation.md) and [release notes](https://github.com/kubernetes-incubator/cri-tools/releases/tag/v0.1)) ([kubernetes/features#292](https://github.com/kubernetes/enhancements/issues/292))
