- Everyone who has contributed code to the project has been asked to license their contributions under LPGL and they have agreed. - COPYING file changed to say LGPLv2.1 instead of GPLv2. - GPL changed to LGPL in the header of every single file that a header and header added to the few that were missing one. - Also.. Happy new year!
