Hmm, that's a good question. We haven't published a list like that - you might just have to try a Google search to find someone who has.
The other thing I'd say though is: don't bother. Just start using OG12. If you see a problem you recognize, skip it. If you don't recognize a problem, then it doesn't matter whether you did already see it in OG13. You might as well do it again. :)
