A lot of the changes can be found on pages 6-7 of this. Only other major change I'm privy to (finishing up my DM course this month) is the inclusion of the Instructor Manual as others have mentioned -- believe previously (we're already using the new crew pack for my class, so just repeating what I've heard) you just got a CD that only discussed DM-led programs.
Not sure if the "PADI Pro Logbook" is new in this crewpack or was included in the prior ones, but that might be new as well. And the hologram emblem thingy, of course.
