<br><font size=2 face="sans-serif">Dear All, </font><font size=3><br>
</font><font size=2 face="sans-serif"><br>
Just wanted to let you know that all the IBM-owned code licensed
under the CPL version 1.0 on COIN-OR has been approved by IBM to migrate
to the new version of the license, and the IBM-PM's are starting to make
the license change. </font><font size=3><br>
</font><font size=2 face="sans-serif"><br>
This is something that the community has been asking for. I'm delighted
the IBM-PMs have the green light they needed to move forward, and I hope
all the CPL-code on COIN-OR will migrate to the new version of the license
(i.e., EPL) to make it easier for those of us who would rather focus on
algorithms rather than legal. </font><font size=3><br>

-------------------</font><font size=3> </font><font size=2 face="sans-serif"><br>
The license originally used by IBM for COIN-OR projects was the CPL (Common
Public License) version 1.0. The CPL has been "deprecated
and superseded" by the Ecplise Public License (EPL)...in other words,
the CPL version 2.0 is the EPL. This is goodness because the EPL,
while similar, has 2 "new and improve" features: (i) the
license steward is the Eclipse Foundation (not IBM) and (ii) the
EPL does not have the "defense termination clause" (i.e., the
patent retaliation bit) which was rather draconian and a point of objection
by some. Like many licenses, the terms of the CPL version 1.0 has
a provisions in the event the license steward modified the license. The
terms permits the Program to be distributed under a new version of the
license (i.e., the EPL). This means the license for CPL code can
legally be switched to the EPL without needing any additional permission
from the Contributors. For more, see </font><font size=3 color=blue><u><br>
