For a planned development of version 3.x ^[2] no commits have been made to the 3.0 codebase since 2011.^[3]

In 2011 a fork of the 2.x codebase titled "WinMerge 2011" was created. This new branch has continued to see active feature and bug fix development. It has also removed ATL/MFC dependencies so that WinMerge can be built using the free Visual C++ Express editions.^[4]
