Yes, current situation is sort of a mess. I suppose 1.5.3 (and 1.5.4) are the winning chain. Kind of a shame since 1.5.5 was a nice update but no one is using it. To make matters worse the original source was update to 1.5.5 but still no one has switched. Doing so now produces problems for the exchanges as all transactions would not have occurred on 1.5.5.

What to do?
