Trolltech has released Qt 4.0 both under commercial and GPL licenses for X11, Mac OS X and MS Windows. It is the first time that a MS Windows GPL edition is available. To celebrate the release Trolltech employees have created a song and a music video. Read the Qt 4 Overview and the online Qt Reference Documentation for more information. You can download Qt from ftp.trolltech.com or from one of its mirrors. Work on KDE 4 has already started with making a development branch of KDE compile and run with Qt 4.
Unlike previous Qt releases, Qt 4 is a collection of smaller libraries which also allowed the restructuring of commercial offers into Qt Console for non-GUI development, Qt Desktop Light replacing the Professional and Qt Desktop comparable to Enterprise editions.
