Nokia released beta versions of Qt 4.7 and Qt Creator 2.0. Both are now available for download, testing and feedback from the official Qt website qt.nokia.com.
A major feature in the Qt 4.7 beta release is a beta version of Qt Quick, the new high-level UI technology that enables developers and designers to work together to create animated, touch enabled UIs.
In addition, the Qt 4.7 beta includes an update of the Qt WebKit Integration and further progress on planned performance and quality process improvements for Qt.
