CrossOver Games 7.2.0 has a fix when running Steam with Compiz, improvements to the City of Heroes game, formal support for SPORE, improved support for World of Warcraft: Wrath of the Lich King, and improved support for the latest version of the Steam client. Beyond that, CrossOver Games 7.2.0 is running on a new version of WINE and there are also a number of DirectX improvements that is supposed to improve the experience on a number of games. There are also a few OS-specific improvements in the Mac OS X build.
The change-log can be found at CodeWeavers.com. If you didn't receive a free copy of CrossOver Games from the CodeWeavers Lame Duck Challenge, a trial version of CrossOver Games is available while the full version is available for $40 USD. We imagine that CodeWeavers will soon have out an update for their CrossOver Office software.
