Bordeaux 1.2 was released today and its a major upgrade over the initial 1.0 release, version 1.2 comes with Office 2007 support, better IE support and cellar support. Cellars are in short just another name for bottle support, with the new cellar support each application or game can be installed into its own wineprefix "cellar" and on top of that you can install unsupported applications and games into their own unsupported cellar. This gives you a sandbox to test in while leaving your supported applications and games in a safe environment.
