A new Warhammer Fantasy Battle 8th edition rulebook Errata (amendments) and FAQ (clarifications) has just been released by Games Workshop.
I haven't even got to the stage where I'm actually questioning the rulebook yet (I'm still trying to overwrite my 7th edition memory bank !) However, it looks like some other people have and Games Workshop have responded. Sadly, there are also some corrections to the new rules but not too many.You can find the 6 page pdf at the foot of the Warhammer Army Errata / FAQ page below (copy link into your browser):-
