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.
It also contains a lot of improvements across the board, as well as support for many new applications, notably Microsoft Office 2010. See the release notes below for a summary of the major changes.
This release is dedicated to the memory of Gé (Greg) van Geldorp, who passed away in May 2011. Greg single-handedly designed, built, and maintained the Wine Testbot, which has become a cornerstone of our development process. The high quality of this release owes a lot to his work. He is greatly missed by us all.
