Hewlett-Packard, IBM, SunSoft, and USL announced CDE in June 1993 as a joint development within the Common Open Software Environment (COSE) initiative. Each development group contributed its own technology to CDE.
CDE has been ported to Linux and BSD derivatives. And it has now been released under an Open Source licence by The Open Group. The latest version so far is v2.3.2 released 10 months ago.
