It was finally time to create version 4.0, and if You look closely you will soon understand why I have decided to create
a new version. As a SCR it is great for day trips, as a CMF CCR or as a MCCR it will be just perfect.
I will during the year try out several MCCR designs. I will share most of my experiments on this page. Enjoy!
