Well I haven't had any issues, many people I know have had no issues. I've not seen that many people around the net complain that there are issues with the online. So, the logical conclusion is that it's a problem on your end, not theirs. As such, of course there is no word for a stability patch.
Also, if there hypothetically were any issues, it'd be server side, not client side, so they wouldn't need to inform us of a patch on it, because they'd fix it on their end and it wouldn't require a patch.
I still disagree with you on the item thing. Aside from the existence of coins and the fact they are one of the common items when you're in first, it's exactly the same as it has always been.
