Andrew usually puts more focus on new features than changes which could cause older applications to fail -- which is what you'd expect in a document titled "What's new in ..." :-)
I have fixed minor incompatibilities many times. Adrew's work was always my reference for that changes. Eventualy some changes weren't there, and it was always a pleasure to mention them to Andrew.
OK. The question is, who's going to write the migration guide? One problem is that often specific migration issues don't surface until after the release is made.
I'd rather help Andrew appending additive porting information in his already excellent work. I'm sure he will appreciate any construtive comments about the paper.
