Hi keyi,

re:
> Could you give very rough time estimation of when v4 might be released?

I'm sorry but I just don't know right now. Any estimate that I would give right now would just be a wild guess and not much chance of being remotely accurate.

I'd say beginning of 2016 is not likely though for a release, it's still not even in beta release yet. It will need to be in beta release for at least 6 months or so probably before the final release would be ready.
