Why X.Org Foundation?
In a period between close to the end of 2003 and beginning of 2004, there were attempts from leading XFree86.org project members to apply a few restrictions on the existing 1.0 license of the upcoming XFree86 X4.4.0 release. Since not all (developers, distributors, hardware vendors) were able or willing to agree with and implement that new licensing policy in their code, their development process and their products, they consequently split up and rejoined in the form of the X.org Foundation.
As a base for their future works, they took one of the last code snippets covered by the old license and joined that with the still existing and freely available codebase from X.org. Further taking responsibility for the contents in the x.org domain made them the de-facto successor of XConsortium. With their accumulated development power and their joint efforts, there were already two major releases and a patch-level release in 2004, a second patch-level release in early 2005, and major releases each year since. A current summary of the state of the foundation can be found in the most recent Annual Report.
Details on any major X Windows Release can be located through the Releases page. The Foundation provides funding for various kinds of activities that advance X.Org, most notably student development and workshops and meetings. Traditional contracting for X Window System development is explicitly not funded by the Foundation, among whose purposes is to encourage development by volunteers.
