The version 1.2 of the well know wine is now released and you can download it from the next link. If you don't know what wine is, let me explain a little and short. wine is a program (wine is not emulator) that allow you to run windows programs. Some of the new features from wine after 2 years without a stable release.
This release represents two years of development effort and over 23,000 changes. The main highlights are the support for 64-bit applications, and the new graphics based on the Tango standard.
