+    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.

+
+Qt Designer
+-----------
+
+- Added support for editing menu bars and tool bars.
+
+- Added support for adding comments to string properties.
+
+- Added new static QtForm library with improved
+  QForm::Loader API for loading designer forms at run-time.
+
+- Added support for namespaces in uic generated code.
+
+- Added support for dock widgets in main windows.
+
+- Added support for editing table, tree and list widgets.
+
+- Improved palette editing and resource support.
+
+QTestLib
+--------
+
+- Added QTestLib, the Qt Unit Testing Library. See the "QTestLib" chapter

+- Users of older versions of QtTestLib can use the updater utility in
+  tools/qtestlib/updater to convert existing autotests to work with QTestLib.
+
+Boost
+-----
+
+Added boost compatible syntax for declaring signals and slots. If you
+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.
+
+Meta Object Compiler (moc)
+--------------------------
+
+- Added support for const signals.
+
+Qt Assistant
+------------
+
+- Added -docPath command line option for easy setting of the
+  document root path.
+
+QMake
+-----
+
+- Added support for new FORMS3 profile variable to make it possible
+  to have Qt Designer forms from Qt 3 and Qt 4 in the same project.
+
+- Added support for precompiled headers on win32-g++ (MinGW)
+
+Compilers
+---------
+
+Added support for Solaris 10 on AMD64 with the compiler provided by
+Sun.
