AS2 Plans Revisions

[DLWilliams]

I believe there was a thread discussing this (Acro Sport 2 plans) at one time, saying that it was believed there were 4 major revisions to the plans. I have the "yellow"-ish cover on my plans (cover mostly faded now), and the serial number is 1552. I'm hoping to go over changes in plans with Chris (smizo) in person in another week or so. However, I don't want to miss something important. Is there any listing of what the revisions consisted of? The bottom line question is, do I need to purchase a fresh set of plans? I'd rather spend my money on material.
Thanks for the help.
