There is a summary of the topics that were revised in the beginning, but you have to go look at the individual pages for the actual changes.

As I read it, it's now the gate agents discretion to list someone who is not pre-listed, or went to the ticket counter. If memory serves it used to say that they should accommodate anyone up to 15 minutes before departure. Also it appears they removed off-line flight attendants from occupying the actual FA jumpseat (Not listed in the priority codes).

I just glanced at it last night so maybe I missed something...
