Magick Without Tears

I was listening to the latest couple of episodes of the Thelema Coast to Coast podcast and they made reference to the fact that the New Falcon edition of Magick Without Tears was butchered by Israel Regardie. I have that edition, and I was wondering if someone in the know could either tell me what was cut out, or point me to a breakdown of the differences in that edition and the prior, more complete edition. I've been googling, but I can't find a clear reference.

I know that hermetic.com has the more complete version, I'm just trying to figure out which sections of that I should concentrate on.
