The package:

IP Re-Allocation. (IPR)
IPR will now become an active part of the game. (Scheduled for 14.2) You will get IP Re-Allocation points. These you can use to reset a skill, (point and click) and get the IP back. You can select whichever skill or ability you like - except Map-Navigation.
<snip portion on silly appeasement process that they think will lure exploiters into removing implants and NCU's, hehehe>
They will be backwards compatible, in the sense that if you are level 200 you will get ALL points from all previous title levels.
Reduced AC on humanoid monsters with 60%. (13.8)
Increased effect of Sneak mode, indoors and outdoors. (scheduled for 14.2)
Now "grey" monsters should be very much easier to sneak by than "deep red" ones.
True Invisibility for Sneaking against other players. (scheduled for 14.2)
If you succeed in a sneak check against other players, you will be invisible.
Of course you can still be detected using a Perception check.
Changed Perception pattern of monsters outdoors.
Monsters won't search as big an area for players as they do today. This means there is a greater chance that you will be able to run past, or sneak past, monsters outdoors. This should make travel a lot easier.
