"Trolltech has released the Qt 4.4.0 technical preview, a pre-release that allows software developers to begin experimenting with the new features that the company has implemented for the next version. I compiled the technical preview release from source code and tested it on my desktop computer with Ubuntu 7.10. For testing purposes, I experimented with several of the new features, examined the included demo applications, and created a few simple programs of my own. The 4.4.0 technical preview adds a new concurrency framework, enhanced XML support, the Phonon media framework, and an integrated HTML renderer widget based on WebKit. This release is also the first to include support for rendering widgets on a GraphicsView component - a feature that will enable Qt developers to create richer and more dynamic user interfaces."
