Some graphical tweaks have been made, but you may notice some layout differences as well. That teleporter on the Blue base's balcony has been replaced with a man-cannon and some panels have been added up there for better cover when moving from building to building. Red side's had an extension added to the Engineering Hallway and lost a chunk of the ceiling in the Office.
343 also sent word on the next big title update for Halo: Reach, due on September 21. Initially, the title update won't change anything for you, but come October 4 a special beta playlist will become active with 4-on-4 Objective and Slayer game modes. Here is where 343 will monitor games so that it can continue to shape Reach.
