Hi Skwerm, the current version is v3 , which for Windows is at v3.0 and for Mac it's at v3.1 since there were problems with recent Mac operating systems that needed some changes in MoI in order to run there.

I've been working on a major rewrite for v4 so there has been a longer than normal gap between v3 and v4. It's getting pretty close though.
