Not seen this up here so I apologise if it's common news
From a reliable source
Dreadnought Axe and Shield:
Fenrisian Greataxe S=userx2 AP2 - Mastercrafted
Blizzard Shield S=user AP2 - Grants a 3+ Invulnerable save against all attacks originating from the Dreadnought's front side

Move Through Cover
So no 'Behind Enemy Lines' anymore
Wolf Guard upgrades for Blood Claws and Grey Hunters can indeed have TDA
Wolf Guard Terminator Heavy Weapons are 1 per 5 full models as before (clarification)
Wolf Guard Terminators have also overcome their distrust of teleporters, they can now Deep Strike.

Not much, but I bring what I can.
