=== Qt modules ===
Starting with Qt 4.0 the framework was split into individual modules.<ref>{{cite web|url=https://dot.kde.org/2005/06/28/trolltech-releases-qt-40|title=Trolltech Releases Qt 4.0|publisher=[[KDE]]|date=28 June 2005|access-date=5 August 2013}}</ref><ref>{{cite web |url=https://qt-project.org/doc/qt-4.8/modules.html |title=All Modules &#124; Documentation |publisher=[[Qt Project]] |access-date=8 April 2013 |archive-url=https://web.archive.org/web/20130329130752/http://qt-project.org/doc/qt-4.8/modules.html |archive-date=29 March 2013 |url-status=dead }}</ref> With Qt 5.0 the architecture was modularized even further.<ref>{{cite web|author=Qt Blog |url=https://blog.qt.io/blog/2012/12/19/qt-5-0/ |title=Introducing Qt 5.0 &#124; Qt Blog |publisher=Digia |date=19 December 2012 |access-date=8 April 2013}}</ref><ref>{{cite web|url=https://dot.kde.org/2012/12/24/qt-50-congratulations-qt-project|title=Qt 5.0 - Congratulations to the Qt Project|author=Kyle Morris|publisher=KDE|date=24 December 2012|access-date=5 August 2013}}</ref> Qt is now split into ''essential'' and ''add-on'' modules.<ref>{{cite web|url=https://doc.qt.io/qt-6/qtmodules.html |title=Qt 6 Documentation: All Modules |publisher=Qt Project |access-date=1 December 2022}}</ref>
