PP have released a new errata, check it out here .
a couple of the highlights:
Shield Guard has been clarified - the shield wall model no longer has to be a valid target for it to take the shot (no LOS shenannigans!)
backswing has been re-worded - only the 1st swing is a Normal attack, the second is an additional attack
a number of abilities have been updatee to be Colossal/Gargantuan 'friendly' (especially Saeryn's feat.. ;o) )
Edit: for smart @rses
