Final changes

The license in dolphin says "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".

I see even though wording are not same, they both mean the same thing. ie.(GNU GPL)?So what to do?
