The building that used to be RED's spawn is now smaller and just like any other.
among other things...
(Edit) those other things:
Added shot clock mode to the flag and disabled that pesky CTF overtime.
Proper respawn times are now set.
The building that used to house B is now just a side building.
B itself has been moved to a new area, and so has RED spawn. (RED spawn isn't directly in front of B anymore, too.)
The building right beside A (The one with the health and ammo packs on top) now has a way for BLU team to easily get on top as well.
Skybox is no longer from HL2.
Made the ammo pack beside the barrel stack near A medium rather than small.
