Qt 4 was released almost seven years ago and today is still fresh and competitive in its 4.8 stable branch. Our 5th big iteration deepens four essential aspects of the Qt offering:


* '''Amazing graphic capabilities and performance''', especially manifested in constrained environments like mobile devices. Qt Quick 2 offers a GL-based scene graph, a particle system and a collection of shader effects. Qt Multimedia, Qt 3D and Qt Graphical Effects bring these features even further.

Qt 5 Alpha

The Qt Project is proud to announce the first Qt 5 release, tagged as Alpha. All features of Qt 5.0 are in place, and we welcome testing and feedback from advanced users of the Qt libraries. This is a source-only release - see the Installation section below to build binaries and find binaries published by the community.

All the attention is put now in stabilization, performance and documentation. We hope to celebrate the final release around the "Qt Contributors Summit&quot;:http://qt.io/groups/qt-contributors-summit-2012/wiki (June 21-23, Berlin). All your help is welcome!

Download

The alpha release can be downloaded in various formats "in the release archive&quot;:http://releases.qt.io/qt5.0/alpha/

In a nutshell

Qt 4 was released almost seven years ago and today is still fresh and competitive in its 4.8 stable branch. Our 5th big iteration deepens four essential aspects of the Qt offering:

  • Amazing graphic capabilities and performance, especially manifested in constrained environments like mobile devices. Qt Quick 2 offers a GL-based scene graph, a particle system and a collection of shader effects. Qt Multimedia, Qt 3D 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 new Qt JS backend powered by V8, Qt JSON DB and 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&quot;:http://wiki.qt.io/Qt-Platform-Abstraction. We look forward to seeing Qt running in all kinds of environments!
  • Open development and open governance is assuring wider development and testing of Qt 5 by a growing community including developers from Nokia, the KDE project, Digia, Collabora, Accenture, KDAB and many more companies and individuals. Today we all celebrate!

Release content

The Qt 5 Alpha release includes the following modules:

  • Essentials : Qt 3D, Qt Core, Qt GUI, Qt JS Backend, Qt Location, Qt Multimedia, Qt Network, Qt Qml, Qt Quick, Qt SQL, Qt Test and Qt WebKit.
  • Add-ons : Qt D-Bus, Qt Graphical Effects, Qt Image Formats, Qt OpenGL, Qt Print Support, Qt Publish and Subscribe, Qt Quick 1, Qt Script, Qt Script Tools, Qt Service Framework, Qt SVG, Qt System Info, Qt Tools, Qt Wayland, Qt WebKit Widgets, Qt Widgets, Qt XML and Qt XML Patterns.

Future releases might include more modules. See the full lists of modules available at Qt Essentials Modules and Qt Add-ons Modules.
