We've finished updating [zl], which was the last object to be updated to Max 7! Technically, there are still a couple of other objects that needed updates, but we'll not consider doing them, and this means cyclone 0.3 has finally reached its main goal of updating all objects to Max 7! Hence, after almost 2.5 years we now have a Release Candidate #1 version... HURRAY!!!
