Well no, the new version is 2.2.0 and the version before was 2.1.5 so actualy you got the previous update with the updater.
I'm sorry, I meant "One version behind was was the newest before 2.2.0" I realise that was confusing now. I said it in case there was a bug in 2.1.5's updater that was not present in 2.1.4's.
