MOST of the changes are listed, it's just there's a few that have slipped through the cracks, such as....
Epic monk SR feats give +2 ab (highv)
casting a spell/using a scroll/drinking a potion while in IE drops your discipline by 10 for anywhere between 1-5 rounds highv)
grease spawns little invisible creatures that explode when struck with fire dmg, dealing AOE dmg to everything around them... (skull)
the last and I think only undocumented change that I put in made it so you could summon 5 zombies at a time with animate dead, if you had necro focus. I wasn't sure how to put a cap on the amount you could summon, so it was a problematic change, and I recently removed it.
There's probably other stuff that I can think of off the top of my head.
