The most robust approach is to only use features that exist in both 0.3 and 0.4 specs. For example, don't use "sync" subscription requests because 0.4 doesn't have them and don't reject distribution requests from the hub if they don't have the Link HTTP header because 0.3 doesn't have them. In short, follow the robustness principle<http://en.wikipedia.org/wiki/Robustness_principle>: Be conservative in what you send, be liberal in what you accept.
