Suggest a fix/enhancement

I tried the generated client using Zone.js 0.8.26 and so far everything works fine. But I don't know the internals of it and when zone.js is really used. So I can't suggest a blind update to 0.8.xx. Furthermore I haven't found any compatibility notes between 0.7.xx and 0.8.xx.
