Action Required:
	When upgrading to Kubernetes 1.7 (and a network plugin that supports
	the new NetworkPolicy v1 semantics), to ensure full behavioral
	compatibility with v1beta1:
	1. In Namespaces that previously had the "DefaultDeny" annotation,
	   you can create equivalent v1 semantics by creating a
	   NetworkPolicy that matches all pods but does not allow any
	   traffic:

	   ```yaml

  If streaming is not supported by the server, the reflector will revert to the previous method
  of obtaining data through LIST/WATCH semantics. ([#110772](https://github.com/kubernetes/kubernetes/pull/110772), [@p0lyn0mial](https://github.com/p0lyn0mial)) [SIG API Machinery]
