102To All Licensees, Distributors of Any Version of BSD:
103
104As you know, certain of the Berkeley Software Distribution ("BSD") source
105code files require that further distributions of products containing all or
106portions of the software, acknowledge within their advertising materials
107that such products contain software developed by UC Berkeley and its
108contributors.
109
110Specifically, the provision reads:
111
112"     * 3. All advertising materials mentioning features or use of this software
113      *    must display the following acknowledgement:
114      *    This product includes software developed by the University of
115      *    California, Berkeley and its contributors."
116
117Effective immediately, licensees and distributors are no longer required to
118include the acknowledgement within advertising materials.  Accordingly, the
119foregoing paragraph of those BSD Unix files containing it is hereby deleted
120in its entirety.
