This version supports all known versions of glibc, including the new Native Posix Thread Library (NPTL) interface. This represents a major technical advance for Wine, as glibc instability has been a problem throughout 2003. Support for the Dreamweaver MX Studio was added. Dynamic loading of OpenGL is provided, which allows a much greater range of unsupported applications to run, especially games such as Half-Life. Miscellaneous bugfixes were made for Microsoft Office, Quicken, Visio, and Lotus Notes.
