I'm confused by the lists you put in because "Issues with game before Feb and 1.2" and today are generally the same. We haven't hit 1.2.
Now if you were to say
"Beta to Release" and "Release to 1.1.5" then that is two different gamestates to compare rather than 1.1 to 1.2 and 1.1.5 since 1.2 isn't in yet.
