Hi Paul, the next version is a pretty big transition to 64-bit and to a native Mac build. This has involved a major rewrite and so there has been a longer than normal gap between v3 and v4. V4 is being actively developed though and there is a beta release available to existing users. The last beta release was just 2 months ago, you can find the announcement right here on the forum titled "V4 beta Feb-9-2018 available now".

As far as the forum not being vibrant, I'm confused how you would reach that conclusion. Here on Sunday I see new replies in 8 threads and there are 8841 discussion threads total and I myself have posted 22608 messages. What volume does it have to reach for you to consider it to be vibrant?

It is true that MoI is a small scale operation, it's only one person (myself) working on it, I don't have any sales or marketing department here, and I personally don't like to do marketing myself. I rely on people spreading news of it by word of mouth and trying the demo version to see how they like it.

The overall goal of MoI is not to have a large user base that "corners the market" - it's to provide a different type of CAD program that's friendly for artists instead of only targeted at engineers.

If you don't like supporting small businesses and prefer something with slick marketing from a large corporation you should look elsewhere I guess.
