I just created a new Ipopt release.  It has some bug fixes for the build 
system, but the main difference is that the open source license has 

In this latest release, we switched the license under which Ipopt is 
available from the "Common Public License (CPL)" to the "Eclipse Public 
License (EPL)."  -  a number of Ipopt users had already requested this 

The license IBM used on COIN-OR (CPL, Common Public License) has been 
"deprecated and superseded" by the Ecplise Public License (EPL). The new 
license (EPL) is almost the same as the old with 2 "new and improved" 
features: (i) the license steward is the Eclipse Foundation (not IBM) and 
(ii) the EPL does not have the "defense termination clause" (aka the 
patent retaliation bit) which was a point of objection by some.

Some additional information regarding the licenses might be found at this 
FAQ: http://www.ibm.com/developerworks/library/os-cplfaq.html

Happy Holidays,
