103To All Licensees, Distributors of Any Version of BSD:
104
105As you know, certain of the Berkeley Software Distribution ("BSD") source

107portions of the software, acknowledge within their advertising materials
108that such products contain software developed by UC Berkeley and its
109contributors.
110
111Specifically, the provision reads:
112
113"     * 3. All advertising materials mentioning features or use of this software
114      *    must display the following acknowledgement:
115      *    This product includes software developed by the University of
116      *    California, Berkeley and its contributors."
117
118Effective immediately, licensees and distributors are no longer required to
119include the acknowledgement within advertising materials.  Accordingly, the
120foregoing paragraph of those BSD Unix files containing it is hereby deleted
121in its entirety.
