Revision control
++ 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.

++ ****************************************************************************
++ * General *
++ ****************************************************************************
++
++ Qt library
++ ----------
++
++ - Introduced widget backing store support, allowing semi-transparent
++ (alpha-blended) child widgets and faster widget painting, as well
++ as solving long-lasting issues with non-rectangular widgets.
++
++ - 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.
++
++ - 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.
++
++ - Support for OLE verbs and MIME data handling in ActiveQt.
++
++ - Support for universal binaries on Mac OS X.
++
++ Qt Designer
++ -----------
++
++ - Added support for editing menu bars and tool bars.
++
++ - Added support for adding comments to string properties.
++
++ - Added new static QtUiTools library with improved
++ QUiLoader 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 in the Qt documentation for more information.
++
++ - 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".
++ Added a new keyword to qmake to enable this macro: CONFIG += no_keywords.
++
++ 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.
