I planned to publish this article after 0.8 release, but I think it would be helpful for users to experience and verify these features before 0.8 release. So I sent it out before 0.8 release. I would be very appreciated that users can try these features via branch-0.8, and this is not a full list of 0.8 new features, feel free to add if I miss any important features.
