Look, the 2.0 version didn't work at all for me, I need to still try version 2.0a, but 1.4 still works flawlessly. I don't think there are enough new features on 2.0 (there's certainly some tho!) compared to 1.4 to force you to update. That's why it's still there to download. I'm still using 1.4 like RIGHT NOW.
