-- Integrated support for rendering scalable vector graphics (SVG) drawings and animations, delivering compact, high fidelity images, independent of scale. Qt 4.1 supports Tiny profiles of SVG 1.1 and 1.2.
-- A PDF backend to the Qt printing system, making the creation of PDF files from both desktop and server applications as simple as printing
-- A lightweight unit testing framework that enables rapid, thread- and type-safe testing of Qt applications and libraries.
In addition to these key new features, Qt 4.1 introduces new functionality across the board. Additional new features include:
-- An interactive menu and action editor in Qt Designer, enabling drag-and-drop of actions into menus and toolbars
-- New proxy models to enable view-specific sorting and filtering of data displayed using item views
-- Expanded features for development with OpenGL, including support for pixel and sample buffers
-- A flexible syntax highlighting class added to the Qt text rendering framework
-- Improved integration with Microsoft Visual Studio .NET, including binaries for Visual Studio .NET 2005
-- Compatibility with other C++ libraries improved via 'no_keywords'- freely mix and even connect Qt Signals and Slots with Boost.Signals
-- Support for network proxy servers using the SOCKS5 protocol
-- Support for OLE verbs and MIME data handling in ActiveQt
