Zoo! long time no see my friend.
2.5 changes nothing in the maps. It supports exactly the same maps that 2.0.1 supported. The only change is to the ESAI core, which is now based on the same core as Standard ESAI v4.1.
You will see bigger changes in the maps that I haven't written custom SAI for, if you have ESAI hooked to those maps. I've changed some fundamental aspects of the way ESAI works, and these changes carry over to both the default strategy sets as well as the additional user strategy sets.
Edit: Just to be clear, Mareth Line still contains my changes to the Allied Airfield spawns. I made it so that bots would not spawn way back there unless there was an aircraft available. That is the only map that I've altered in any way, with respect to the map pack. There is an alternate version of Luttich floating about that I did a while back (I think Djinn still has it), but that was unnoficial of course, and just for fun.
