     The focus for Qt 5.4 is mainly about improving the stability, performance,
     and first-time user experience of the product.
 
-    \note The full list of features are found in http://qt-project.org/wiki/New-Features-in-Qt-5.4
-    After the 5.4 Alpha release, the features will be listed in this page.
+    \section1 New Modules
+
+    \list
+    \li \l[QtWebChannel]{Qt WebChannel}
+    \li \l[QtWebEngine]{Qt WebEngine}
+    \li \l[QtWebEngineWidgets]{Qt WebEngine Widgets}
+    \li \l[QtPlatformHeaders]{Qt Platform Headers}
+    \endlist
+
+    \section1 New Supported Platforms
+
+    \list
+    \li \l{Qt for WinRT}{WinRT} now a supported platform
+    \li Windows Phone 8.1 minimum supported version
+    \endlist
+
+    \section1 New Features in Qt 5.4
+
+    \section2 Qt GUI Module
+    \list
+    \li QOpenGLContext is now able to adopt existing native contexts
+        (EGL, GLX, and so on). This allows interoperability among Qt and other
+        frameworks, such as game engines.
+    \li OpenGL ES 3.0/3.1 support is improved. The header file for the highest
+    usable ES version (gl31.h, gl3.h or gl2.h) is now automatically included by
+    Qt's headers in -opengl es2 builds. Vertex array objects, framebuffer blits
+    and multisampling are now supported via the standard GLES3 functions, where
+    applicable.
+    \li Selecting the dynamic OpenGL implementation on application startup is
+    now available on Windows when configured with _-opengl dynamic_. This allows
+    using either opengl32.dll or ANGLE's OpenGL ES 2.0 implementation in Qt and
+    applications without the need for two separate builds of the binaries.
+    \li QOpenGLWidget: The modern replacement for QGLWidget and the counterpart
+    of QQuickWidget.
+    \li QOpenGLWindow: Convenience class for performing OpenGL drawing onto a
+    QWindow.
+    \li QRasterWindow: Covenience class for performing software-based drawing
+    via QPainter onto a QWindow.
+    \li Support for 10-bit per color channels images. These can be rendered to
+    and from, though internally the raster engine will still use 8-bit per
+    color channel. If used as the internal format of a QOpenGLFramebufferObject,
+    the OpenGL paint engine is able to render in full precision if supported by
+    the OpenGL driver.
+    \li WinRT: Added support for native file dialogs.
+    \endlist
+
+    \section2 Qt Core Module
+    \list
+    \li WinRT: Added support for native settings container (local and roaming).
+    \li QStorageInfo: Class for providing information about currently mounted
+    storage volumes and drives.
+    \li QByteArrayList: Convenience class adding similar extra methods on top
+    of QList<QByteArray> as QStringList does to QList<QString>.
+    \li QTabletEvent: several improvements to the input information: added
+    information about the stylus buttons being pressed, the rotation and
+    tangential pressures now have consistent ranges across platforms, the
+    proximity events now include the type of stylus or other tool in use, and
+    manual tests and debug output are improved for better verification of
+    functionality.
+    \endlist
+
+    \section2 Qt Widgets Module
+    \list
+    \li Improved scaling of widget styles based on DPI.
+    \endlist
+
+    \section2 Qt Quick Module
+    \list
+    \li QQuickRenderControl is made public. This API allows efficient rendering
+    of Qt Quick 2 scenes into framebuffer objects. The contents can then be used
+    in arbitrary ways in Qt-based or 3rd party OpenGL renderers.
+    \li Introduced overlay and \e{pull back} headers and footers for ListView.
+    \li Added QQuickFontMetrics, which provides a subset of QFontMetricsF's API.
+    \li Added QQuickTextMetrics, which provides a declarative API for the
+    QFontMetricsF function arguments.
+    \li QQuickWidget is now supported on Android.
+    \endlist
+
+    \section2 Qt Quick Controls Module
+    \list
+    \li Android style.
+    \endlist
+
+    \section2 Qt Bluetooth Module
+    \list
+    \li Support for Bluez5.
+    \li Tech Preview of Bluetooth Low Energy (client side support only, on
+    Bluez 4 & 5).
+    \endlist
+
+    \section2 QPA Plugins
+    \list
+    \li The Wayland platform plugin is now part of the release.
+    \li XCB will now support screen with a depth of 30 (10 bit per color
+    channel).
+    \li More font settings are parsed by fontconfig and GTK platform backends.
+    \li More categorized logging is in use so that you can enable it in the
+    standard ways (qtlogging.ini etc.) instead of needing to set obscure
+    environment variables or uncomment #defines.  The log also provides more
+    complete information, especially about events.
+    \li Support for integer device pixel ratios larger than one has been added
+    to the XCB plugin. The ratio is controlled by the environment variable
+    \c QT_DEVICE_PIXEL_RATIO.
+    \endlist
+
+    \section2 Qt WebKit Module
+    \list
+    \li  Added support for OpenGL accelerated 2D canvas to
+    \l{Qt WebKit Widgets}.
+    \li The Qt WebKit module is considered \e done. It will be replaced by
+    Qt WebEngine. This applies to the widgets as well as to the QML API of
+    Qt WebKit.
+    \endlist
+
+    \section2 Qt Windows Extras Module
+    \list
+    \li Multiple thumbnail images when hovering over an application's taskbar.
+    \endlist
+
+    \section2 Qt Sensors Module
+    \list
+    \li Windows Phone: Added compass and ambient light sensors.
+    \endlist
+
+    \section2 Qt SQL Module
+    \list
+    \li Windows Phone: Added support for sqlite.
+    \endlist
+
+    \section1 Deprecated Features
+
+    \section2 Qt OpenGL  Module
+    \list
+    \li The Qt OpenGL module (which contain classes that start with \e QGL) is
+    now deprecated in favor of the \l{Qt GUI} module (which contains classes
+    that start with \e QOpenGL). QGLWidget can now be replaced by QOpenGLWidget.
+    \endlist
+
+    \section1 List of API Changes
