QT Licensing Reinvented, Again

The QT product, which has changed both licensing and ownership several times in the past, has announced a new liensing policy.  New versions of Qt will be licensed under a commercial license, GPLv2, GPLv3, and LGPLv3, but no longer under LGPLv2.1. Ther will be a “start up license” — preferential commercial terms for small businesses with annual revenue less than $100,000.  QT has a long history of dual licensing, though the exact terms have changed several times.  It was originally developed by Trolltech, transferred to Nokia, and then Nokia transferred certain commercial rights to Digia.   QT is a cross-platform application framework that is widely used for developing application software that can be run on various software and hardware platforms with little or no change in the underlying codebase, while remaining a native application.
