Qt is the standard framework for high performance, cross-platform application development. Trolltech ASA is licensing its Qt cross-platform development framework under the GNU General Public License version 3 (GPL v3), with immediate effect. GNU founder Richard Stallman said:
I am very pleased that Trolltech has decided to make Qt avaliable under GPL v3. This will allow parts of KDE to adopt GPL v3 too. Even better, Trolltech has made provisions for a smooth migration to future GPL versions if it approves of them.
Qt is already available under the GPL v2 and will continue to be so in addition to the GPL v3.
The GPL v3 license will make it easy and safe for free software developers to use Trolltech's Qt with the most recent license framework from the Free Software Foundation. Trolltech hopes that its move will inspire free software projects to use GPL v3 when programming with Qt.
