== Qt 5 ==
Qt 5 was originally expected to be released in June 2012<ref>{{cite web|url=http://qt-project.org/wiki/Qt_5.0/revision/11067 |title=Qt_5.0 | Qt Wiki |publisher=Qt Project |date=2012-03-13 |accessdate=2013-03-19}}</ref> but the release was delayed several times.<ref>{{cite web|url=http://qt-project.org/wiki/Qt-5/revision/15080 |title=Qt 5 | Qt Wiki |publisher=Qt Project |date= |accessdate=2013-03-19}}</ref> It was officially released on 19 December 2012. This new version marks a major change in the platform, with hardware-accelerated graphics, [[QML]] and [[JavaScript]] playing a major role. The traditional C++-only QWidgets continue to be supported, but do not benefit from the performance improvements available through the new architecture.<ref>[http://lists.qt.nokia.com/public/qt5-feedback/2011-October/001622.html Concern about removal of QWidget classes], Qt5-feedback mailing list, 7 October 2011</ref> Qt5 brings significant improvements to the speed and ease of developing user interfaces.<ref name="Thoughts about Qt 5">{{cite web |url=http://labs.qt.nokia.com/2011/05/09/thoughts-about-qt-5/ |title=Thoughts about Qt 5 |date=9 May 2011 |accessdate=9 May 2011 |first=Lars |last=Knoll}}</ref>
Framework development of Qt 5 moved to open governance, taking place at qt-project.org. It is now possible for developers outside Nokia/Digia to submit patches and have them reviewed.<ref>[http://labs.qt.nokia.com/2011/10/21/the-qt-project-is-live/ The Qt Project is live!] by Lars Knoll, labs.qt.nokia.com.
