The SoWin library is a C++ GUI toolkit that binds together the Coin rendering library with the user interface parts of the MSWindows Win32 API, thereby providing application programmers a convenient method of using the Coin library from MSWindows development environments. This is a release to accompany an SoQt release we had to do because of a critical bugfix. The previous SoWin release, 1.3.0, did not have this bug. Nevertheless, there has been a lot of minor issues fixed since the release of 1.3.0, so upgrading should be worthwhile.
