Talisman:
Notwithstanding the fact that I think DD knows pretty much everything, 
the text reads:

*The castle's magical fortifications have been strengthened over the 
summer, we are protected in new and more powerful ways...*(168). 

New protections, both magical in nature and plural in number are 
explicitly referenced.  That doesn't fit with an interpretation that DD 
merely means that the Order is helping out, which they have also done 
in the past--both officially and unofficially.

The straight-forward answer is that new enchantments are in place.
