Qt is een open source, platform-onafhankelijk framework voor applicaties en hun interface. Hiermee kunnen applicaties worden ontwikkeld die vervolgens zonder aanpassingen gecompileerd kunnen worden om te draaien op verschillende desktopsystemen en embedded systemen. De ontwikkelaars van Qt Software, de naam die Nokia na de overname van Trolltech aan deze divisie heeft gegeven, hebben versie 4.5.3 van Qt uitgebracht. De bijbehorende aankondiging en lijst met veranderingen zien er als volgt uit:
