Though I was quiet for the past weeks, I was not sitting doing nothing. There is a new project I'm currently working on and it takes lots of my spare time. I'll share the info once it will be mature enough.
Anyways, regarding Mission-X I believe that the final build will arrive soon, there should not be any special changes, but I hope that I'll finish some of the tutorials, at least the basic ones, and release a final documentation, though the current state is fine.
I hope to be able to share some of my current work soon, until then have a great simming.
