How do I get new models?

Hello I have searched all over the website and cant find a way to get the updated models. If someone could please link me information it would be much appreciated.

if you have a 5.4.8 client you can add WoD models by following this guide: http://forum.warmane.com/showthread.php?t=319808

Edited. I would have deleted it, but forum didn't allow me, in spite of giving me the option.
