Qt Logo The first bugfix release for version 4.6 of Qt GUI toolkit, acquired by Nokia in 2008, is now available. Similarly, an update for the cross-platform Qt Creator development environment, version 1.3.1, is also available to download. Both combine numerous fixes with performance enhancements and revised documentation. Qt 4.6.1 contains more than 90 changes, whilst debugging (especially under Mac OS X 10.6 'Snow Leopard') and the C++ editor have both been revised in Qt Creator. Both technologies are available on the Qt project's Git resource under the open source LGPL 2.1 license.

Qt 4.6 was finally released at the start of December. It was the first version that was capable of running on the Symbian mobile operating system, on both the 3rd and 5th editions of S60. Over time, the plan is for Qt to replace Symbian's existing graphics system. Qt also runs on Nokia's other operating system, Maemo. Additionally, the development team have now released a beta version of the library for Maemo 5. The release announcement advises that all of the APIs are feature complete. The Qt beta for Maemo can be downloaded from the project's website.

Qt is a framework written in C++ available for Linux, Windows and Mac OS X, which offers the same functions on all three platforms. It forms the basis for the open source KDE Linux desktop. After taking over Trolltech, the company that originally developed the framework, Nokia released the library under the LGPL and provided open access to the code repositories.
