Checking closer into the source licensing issue we discussed the other day about including GPLv3 OpenDWG support into GPLv2 LibreCAD, it appears that the existing LibreCAD license permits the code to be released at any GPL license above 2 anyway.

So you have the freedom to upgrade the LibreCAD license to GPLv3 if you want (and anybody else can fork it to GPLv3 if they wanted anyway) so there is nothing stopping us from including OpenDWG now instead of waiting for permission to put GPLv3 code into a GPLv2 program.

From the comment header to /src/main/main.cpp:
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.

...and so the real questions are:
1. Does anybody have a problem with upgrading the LibreCAD license from GPLv2 to GPLv3?
2. Does anybody know of a reason why we can not upgrade the license?
3. Does anybody think that upgrading is a bad idea?
