Qt 4.5+ To Be Relicensed Under LGPL

Free Software

Last January when KDE 4 was released it was shared by Trolltech that Qt would be relicensed under the GNU GPLv3. Less than two weeks after that announcement, Nokia acquired Trolltech, the company behind the Qt tool-kit. In September, Trolltech was renamed to Qt Software. Almost a year to the day after Trolltech announced Qt would be put under the GPLv3, Qt Software has announced Qt 4.5 will be relicensed.

Beginning with Qt 4.5, Qt will be put under the LGPL 2.1 license. Qt will continue to also be distributed under the GPLv3 as well as Nokia's commercial license. As a result of this move, the KDE libraries for the K Desktop Environment will also be put out under the LGPL.

More information on this Qt relicensing announcement can be read at KDE.org.
