Plague Zombies can purchase additional models but not other options.
Axe of Blind Fury is available to Daemons of Khorne and models with the Mark of Khorne.
Note 5 on the Chaos Wargear List changed to include 'and Daemons of Khorne'.
Chaos Terminators - Terminators can choose any of the following three options.
Helbrute points value changed to 100 - what?
EDIT: My thoughts on the changes.
Plague Zombies - obviously this is great.
Axe of Blind Fury - the Black Mace is still the superior option overall, however being S8 base means you would be a moving instant-death machine against things like Nobz and Paladins.
Terminators - thank goodness for that. The biggest complaint (at least that I've seen) about the codex is now fixed. I hope no-one actually went through with removing the arms of their Terminators!
Helbrute - again, what? Why the points reduction? I really don't understand. We already get a better deal than basic Loyalist Dreadnoughts (until you bring Drop Pods into the equation), why was this necessary? Was it a misprint? I dunno. It is kind of funny that we get the same profile as a Loyalist Dreadnought for the cost of an infantry flamer points less and get Extra Armour for free when they have to pay thrice our points reduction for it.
