Espoo, Finland — Nokia today announced that its Qt cross-platform User Interface (UI) and application framework for desktop and embedded platforms will be available under the Lesser General Public License (LGPL) version 2.1 license from the release of Qt 4.5, scheduled for March 2009. Previously, Qt has been made available to the open source community under the General Public License (GPL) license. In addition, Qt will now be available from the new domain, www.qtsoftware.com.
The move to LGPL licensing will provide open source and commercial developers with more permissive licensing than GPL and so increase flexibility for developers. In addition, Qt source code repositories will be made publicly available and will encourage contributions from desktop and embedded developer communities. With these changes, developers will be able to actively drive the evolution of the Qt framework.
Qt 4.5 will also be available under commercial licensing terms, while licensing for previous versions of Qt remains unchanged. In addition, service offerings for Qt will be expanded to ensure that all Qt development projects can have access to the same levels of support, independent of the selected license.
Good news for those of us too cheap to pay the $4950 per developer multi-platform license.
