This is not true. Because the contributions were for a GPL'd codebase and are derived (subclassing, interfacing) from it, they are automatically GPL2.

Of course has every author the right to do whatever with his/her own code in parallel, but this leads away from the topic. > Still, GPL V2 has worked fine for us, so I don't think this is a burning > issue. > In short there is an overview on http://en.wikipedia.org/wiki/GNU_General_Public_License#Version_3 I personally favour GPL3, because it advocates free and open software more efficiently.
