X11R6.7.0, the first version of the Xorg Server, was forked from XFree86 4.4 RC2, owing to disagreement with the new license for XFree86 4.4 final, with other changes folded in from X11R6.6. Many of the previous XFree86 developers have joined the project, which is run in a more open manner than XFree86. (SeeThe Cathedral and the Bazaar.)
