The Halo for Windows v1.06 Hotfix addresses a rare crash bug that could occur if a malicious individual (hacker) purposely imitates a game server and sends invalid data to clients who try to browse the server list. This hot-fix changes the version number of Halo for Windows and the Halo for Windows Dedicated Server to v1.06 from v1.05.
NOTE: Due to an incompatibility discovered between some systems and the updated Auto-patcher released with version 1.05, users of 1.05 will have to manually download an updated Auto-patcher 1.06 and run it from the Halo directory to receive this latest update. Users updating form prior versions can auto-patch from the game. This issue is addressed for any future patches beyond 1.06.
