I've never tested/used it.
But if I read here :
at the bottom of the question I can find :
I read here that the 1.6.1, 1.6.2 and 1.6.3 versions contain only bug fixes (and presentation related changes) and do not contain new features, compared to the 1.6 version released on the 27th June 2013.
So, in theory , it should work over the 1.6.3.
Nevertheless, I see a lot of issues and complaints in using it (but, as I said before, I do not have direct experience on it).
