Quote:It's better to make 3 packages with 3 versions because a lot of trackers don't allow f.e. 0.9.3 (I'm on 2 of those trackers) Some don't like 0.9.4 etc etc

Then users can always create one themselves. From the XBian point of view, we just offer one package. Up to you what version it should be. As long as it isn't an unstable version with lots of memory leaks.
