Now Available to Commercial and Open Source Developers

Oslo, 22 February - 2008 - Trolltech today released Qt 4.3.4 to commercial customers and the open source community. Qt is the standard framework for high-performance cross-platform application development, and Qtopia Core is the leading application framework for single-purpose devices powered by embedded Linux. Both releases are available for customer use, evaluation and open source download.

Qt includes bug fixes made since the release of version 4.3.3 in December 2007.  In addition to professional support, Trolltech commercial license holders receive regular releases as part of their annual license.  All improvements to Qt are also released to the Open Source Community through GPL editions of both frameworks.

For detailed information on fixes and optimizations included in the releases, please consult the changes-4.3.4 file found in the distribution files, or browse the information contained in the Developer pages at http://www.trolltech.com/developer/notes/changes/changes-4.3.4/


Full Source Evaluations and Open Source Downloads

Qt is available both as full source commercial evaluations and Open Source Editions.  Free 30-day evaluations are feature identical to Trolltech's commercial products and offer full access to source code and professional support during the evaluation period.  The Open Source Editions are released under the GPL for open source development.  Follow the links below to download Qt 4.3.4:

Changes 4.3.4

Qt 4.3.4 is a bug-fix release. It maintains both forward and backward
compatibility (source and binary) with Qt 4.3.0 through Qt 4.3.3.

The Qt version 4.3 series is binary compatible with the 4.2.x, 4.1.x and
4.0.x series. Applications compiled for Qt 4.0, 4.1 or 4.2 will continue to
run with Qt 4.3.

Build System
------------

    * MinGW: Ensure that PRE_TARGETDEPS and POST_TARGETDEPS are properly
