Qt 5 is now available. This is the first major release under Digia, who recently acquired Qt from Nokia. Key additions include support for C++11 and HTML5 along with an integrated WebKit2 browser engine. Both commercial and open source versions are available.

Qt is the most widely-known and -used portable UI framework for C++, used by nearly half a millon developers worldwide. It offers native code performance and modern sophisticated user experiences across desktop, embedded, and mobile platforms.

More details from the Qt 5 product page:

Our 5th big iteration deepens four essential aspects of the Qt offering:

Amazing graphic capabilities and performance, especially manifested in constrained environments like embedded and mobile devices. Qt Quick 2 offers a GL-based scene graph, a particle system and a collection of shader effects. Qt Multimedia and Qt Graphical Effects bring these features even further.

Developer productivity and flexibility, making JavaScript and QML first class citizens while keeping the C++ foundation and Qt Widget support. The addition of Qt WebKit 2 should make HTML5 developers feel at home.

Cross-platform portability is now simpler for OS developers thanks to the new structure of Essentials and Add-ons modules, plus the consolidation of Qt Platform Abstraction. We look forward to seeing Qt running in all kinds of environments! Next up is full Qt support on iOS and Android and work here has already begun.

Open development and open governance is assuring wider development and testing of Qt 5 by a growing community including developers from Digia, KDAB, Intel, Collabora, Accenture, the KDE project, and many more companies and individuals. Today we all celebrate!
