Wine 1.4 has been released today and includes support for a wide range of applications, including Microsoft Office 2010. This release represents 20 months of development effort and over 16,000 individual changes. The main highlights are the new DIB graphics engine, a redesigned audio stack, and full support for bidirectional text and character shaping. There are some major architectural changes and a new audio stack designed around the newer Vista / Win 7 system and integrated into the native audio system. Almost every other subsystem received substantial updates, including Direct3D, the Gecko-based web browsing components, and better internationalization.
