Every news of Winamp and its entities. Winamp has announced that it is opening up its source code to enable collaborative development of its legendary player for Windows.
My guess is this is a win32 program or a codebase that is very Windows specific. It was probably discarded because it did not port very well to other platforms. Again, just a guess.
Still, it's nice to see such a historicaly popular program get its source officially released.
