  * Enhance CNI plugin compatibility, supports flannel, calico, weave and so on.
  * Pass all CRI validation conformance tests and node end-to-end conformance tests.
  * Add experimental Unikernel support.

* [alpha] [cri-containerd](https://github.com/kubernetes-incubator/cri-containerd): CRI implementation for containerd is now v1.0.0-alpha.0, [[@Random-Liu](https://github.com/Random-Liu)]
