+Qt 4.1 introduces many new features as well as many improvements and
+bugfixes over the 4.0.x series. For more details, see the online
+documentation which is included in this distribution. The
+documentation is also available at http://qt.nokia.com/doc/
+
+The Qt version 4.1 series is binary compatible with the 4.0.x series.
+Applications compiled for 4.0 will continue to run with 4.1.

+
+ - Integrated support for rendering Scalable Vector Graphics (SVG)
+ drawings and animations (QtSvg module).
+
+ - A Portable Document Format (PDF) backend for Qt's printing system.
+
+ - A unit testing framework for Qt applications and libraries.
+
+ - Modules for extending Qt Designer and dynamic user interface
+ building.
+
+ - New proxy models to enable view-specific sorting and filtering of
+ data displayed using item views.
+
+ - Additional features for developers using OpenGL, such as support
+ for pixel and sample buffers.
+
+ - A flexible syntax highlighting class based on the Scribe rich text
+ framework.
+
+ - Support for network proxy servers using the SOCKS5 protocol.
+

+
+Qt Designer
+-----------
+
+- Added support for editing menu bars and tool bars.
+
+- Added support for adding comments to string properties.

+define the macro QT_NO_KEYWORDS "Q_SIGNALS" and "Q_SLOTS" are
+recognized as keywords instead of the default "signals" and "slots".
+
+ActiveQt
+--------
+
+QAxServer now supports mime-type handling - a ActiveX control can be
+registered to handle a certain file extension and mime-type, in which case
+QAxBindable::load and QAxBindable::save can be reimplemented to serialize
+the object.
+
+Build system
+------------
+
+Added support for linking static plugins into the application.
+
+Qt 3 to 4 Porting Tool
+----------------------
+
+Q(V|H)BoxLayout and QGridLayout usage is now ported to use
+Q3(V|H)BoxLayout/Q3GridLayout, to retain the margin/spacing
+behavior as in Qt 3.

+--------------------------
+
+- Added support for const signals.
+
+Qt Assistant
+------------
+
+- Added -docPath command line option for easy setting of the

+
+- Added support for precompiled headers on win32-g++ (MinGW)
+
+Compilers
