Since I don't really pay attention to specific release dates for OSs or for KM, I should be cautious saying yes here. But I think if there's a way to search these forums for old posts from old users like me, you will see I specifically raised this issue years ago. So if we can find those posts we can put a minimum duration for this problem.
