Are there?  I just read through the list for the second time, and I 
still haven't found anything that looks like it affects Bugzilla.  I do 
agree that more bugs will be found now that it's in production, 
however.  I found one myself the other day after upgrading a b.m.o 
mirror from 3.32.54 to 4.0.12 while leaving b.m.o at 3.23.44:

In fairness, the MySQL manual does say, "With regard to version 4.0, we 
recommend using same version on both sides," although it isn't clear if 
they are discouraging 3.23.x <-> 4.0.x replication or just 4.0.x <-> 
4.0.y replication.
