v188.8.131.52: Some users reported problems with keyboard movement after updating to 1.04, though the bug could not be duplicated in testing. However, we did find and fix a random memory trasher in Halo's input system which may have been causing this problem. We apologize for any inconvenience this may have caused.
v1.0.4: The Mac code has been synchronized with version 1.04 of the PC code (Build 607). The PC code had been updated with a GameSpy Security Hot-Fix that addresses a rare crash bug that could occur if a malicious individual (hacker) purposely tries to exploit the GameSpy CDKey SDK on either Mac OS X or Windows.
