Those versions are so far away codewise, that I there surely is no easy answer. _If_ your code was in mainline all the way from 1.1.6 to 2010.12 you could have used "git bisect", but as this is (very likely) not the case, this will not work for you. So the "easiest" way is to start debugging the problem yourself.
