X Window System
Version 11 Release 7.x ongoing development

The X.Org Foundation provides an Open Source version of the X Window System that supports Linux, BSD, Solaris, Cygwin and MacOS X on Intel and other platforms.

This software has been produced by the many contributors to the X.Org community and members of the X.Org Foundation and includes code from the X Consortium, the Open Group and the XFree86® Project.

The X11R7.7 release in 2012 was our last planned roll-up release of all the components of the X Window System as a unified release. Since then we have been releasing the individual modules as needed — see the xorg-announce archives for details of those releases, and https://www.x.org/releases/individual/ for downloads.
