The XFree86 Project
modified their license (fully effective as of the upcoming 4.4.0 release). The updated license change applies to the base XFree86 license, and to source files that explicitly carry a copyright notice in the name of The XFree86 Project, Inc. Copyrights and licenses in the names of others
will not be affected by this change, however
some fear that these changes might be GPL-incompatible.
