Has StackOverflow fixed the issue of software versioning and repeat questions? More than once I've run into a question that was relevant for me, but was marked as a duplicate, where the referenced original thread applied to an earlier version of the software. It's infuriating! I don't need to know how to solve that with Python 2.7... I need to know why it's busted on 3.5!
