I could not release 2.1.6

Because I was busy and tired last weekend, I could not check whether 2.1.6 runs completely. Therefore I did not release the stable edition yesterday. If I will return home early, I will do final test HEAD and release it.

Also this week is very very tough. I pay attention to my helth. We have tried to add a new release manager, but we have failed all trying. Umm.
