was supposedly buggy. How do I know the LoopIIIv5.0 or LoopIV versions aren just as bad?
A lot of things changed behind the scenes between the old versions and the newer ones, generally for the better. Among them was a much higher commitment to software quality as a core value of Aurisis Research, the company developing Loop. LoopIIIv5.0 was beta tested extensively before release, until nobody could find anymore bugs. Same with LoopIV. LoopIIIv5.0 shipped for 5 years, and I believe only one bug was ever found in it. LoopIV has only been available for a few months, but so far there have not been any problems.
