Qt 5 was officially released on 19 December 2012. This new version marked a major change in the platform, with hardware-accelerated graphics, [[QML]] and [[JavaScript]] playing a major role. The traditional C++-only QWidgets continued to be supported, but did not benefit from the performance improvements available through the new architecture.<ref>{{cite mailing list|url=https://www.mail-archive.com/qt5-feedback@qt.nokia.com/msg01420.html|title=Concern about removal of QWidget classes|mailing-list=Qt5-feedback|date=7 October 2011}}</ref> Qt 5 brings significant improvements to the speed and ease of developing user interfaces.<ref>{{cite web |url=https://blog.qt.io/blog/2011/05/09/thoughts-about-qt-5/ |title=Thoughts about Qt 5 |access-date=9 May 2011 |first=Lars |last=Knoll|publisher=Digia|date=9 May 2011}}</ref>

Framework development of Qt 5 moved to open governance at qt-project.org, which made it possible for developers outside Digia to submit patches for review.<ref>{{cite web|url=https://blog.qt.io/blog/2011/10/21/the-qt-project-is-live/|title=The Qt Project is live!|first=Lars|last=Knoll|publisher=[[Nokia]]|date=21 October 2011|access-date=8 February 2012}}</ref>
