On Macintosh, the shipping (non-Qt) version of our application has only a 32-bit version. Once we release the new version (using Qt), we will want to continue to provide a 32-bit version as well as a 64-bit version so that users using existing external libraries (32-bit) can continue to use our application. A lot of these libraries are pretty old and not likely to be recompiled for 64-bit any time soon, so that's why we really need to ship a 32-bit version of our application. To answer Thiago's question, we are building our own version of 32-bit Qt on OSX from the 5.4 branch just fine (though we're not using Webkit, for what that's worth). Adam
