     \title What's New in Qt 5.8
     \brief Lists the new features in Qt 5.8.

     \section1 New Features in Qt 5.8

     \section2 Qt Core Module
     \list
         \li Added at(), operator[], mid(), right(), and left() functions to
             QLatin1String.
     \endlist

     \section2 Qt GUI Module
     \list
         \li Added \l {QTouchEvent::TouchPoint::}{uniqueId()} and
             \l {QTouchEvent::TouchPoint::}{rotation()} to QTouchEvent.
         \li Added support for dithering when converting to all QImage formats.
         \li Made the QOpenGLTextureBlitter API public; used particularly in Qt
             Wayland.
         \li Added \l {QFontMetrics::}{capHeight()} to QFontMetrics,
             QFontMetricsF, and QRawFont.
         \li Added selection handles on Android, with an edit menu for copy and
             paste.
     \endlist

     \section2 Qt Quick Module
     \list
         \li Refactored the Qt Quick scene graph to remove its OpenGL
             dependency, enabling backends based on other graphics APIs such as
             Vulkan or Direct3D.
         \li Integrated the software renderer (previously known as the Qt Quick
             2D Renderer) for Qt Quick as a proper scene graph backend.
         \li Implemented support for partial updates in the software renderer.
         \li Added an experimental Direct3D 12 backend.
         \li Implemented caching of code and data structures generated from
             \c .qml and \c .js files to disk, reducing start-up time and memory
             consumption. The resulting \c .qmlc and \c .jsc cache files are
             memory mapped.
         \li Cleaned up touch and mouse event delivery, and added a new internal
             class \c QQuickPointerEvent for this purpose.
     \endlist

         \li Added new experimental \e platform QML types:
             \c MenuBar, \c Menu, \c SystemTrayIcon,
             \c ColorDialog, \c FontDialog, \c MessageDialog,
             \c FileDialog, and \c FolderDialog.
     \endlist

     \section2 Qt WebEngine Module

         \li Added \l {Qt WebEngine Features#View Source}{view-source} scheme
             support.
         \li Added support for spellchecking with custom .bdic files.
         \li Made tooltips (HTML5 global tile attribute) visible.
         \li Added support for metadata (\c @include, \c @exclude, \c @match,
             \c @name, and \c @run-at) in user scripts.
         \li QML: Enabled the use of custom dialogs and context menus.
         \li QML: on eglfs, took the built-in dialogs based on Qt Quick Controls
             2 into use.
         \li Added support for printing.
         \li Added a setting to enable printing of CSS backgrounds.
     \endlist

     \section2 Qt Bluetooth Module
     \list
         \li Added Bluetooth Low Energy Peripheral support on macOS, iOS, and
             WinRT.
     \endlist

     \section2 Qt Multimedia Module
     \list
         \li Added QAudio::convertVolume() and a matching QML method to convert
             audio volumes from one scale to another; for example, from
             logarithmic to linear scale.
         \li Added support for rendering YUV 4:2:2 (YUYV, UYVY) video frames to
             VideoOutput QML type.
     \endlist

     \section2 Qt Network Module
     \list
         \li Added support for TLS-PSK ciphersuites on server side.
         \li Added support for configurable Diffie-Hellman parameters.
         \li Added support for HTTP/2 in Network Access Manager.
     \endlist

     \section2 Qt WebSockets Module
     \list
         \li Added support for TLS-PSK ciphersuites on client and server side.
     \endlist

     \section2 Qt Charts Module
     \list
         \li Added a candlestick chart type.
     \endlist

     \section2 Qt 3D Module
     \list
         \li Focused on maturation: Bug fixes, improving performance and test
             coverage.
         \li Added a \e {paint to texture} feature using QPainter.
         \li Added optional support for issuing commands to Qt3D aspects (for
             example, from a profiler).
     \endlist

     \section2 Embedded Platforms
     \list
         \li Enhanced multi-screen capabilities and configurability with eglfs
             when running on KMS/DRM, both with GBM and EGLDevice/Stream.
         \li Added support for 90 and 180 degrees rotation of software-rendered
             content (QWidget) in eglfs.
     \endlist

     \section2 Configurability (Qt Lite Project)
     \list
         \li Qt 5.8 comes with a rewritten configuration system that allows for
             easy customization of Qt builds. The main focus of this feature is
             for the Device Creation, but it can also be used to tailor a Qt
             build for mobile or desktop platforms. The new configuration system
             allows removing individual pieces of functionality and APIs from
             Qt, creating a more lightweight set of libraries for deployment.
     \endlist

     \section1 New Modules
     \list
         \li \l {Qt Wayland Compositor}
         \list \li Provides a framework to develop a Wayland compositor.
         \endlist
         \li \l {Qt SCXML}
         \list \li Enables static and runtime integration of SCXML models into
                   Qt code.
         \endlist
         \li \l {Qt Serial Bus}
         \list \li Provides access to various industrial serial buses and
                   protocols, such as CAN and ModBus.
         \endlist
     \endlist

     These modules were previously released as technology previews, and are
     now fully supported Qt add-on modules.

     \section1 Technology Preview Modules
     \list
         \li \l {Qt Gamepad}
         \list \li Enables Qt gaming applications to respond to gamepad input.
         \endlist

                   Includes backends for several speech synthesizers on
                   Windows, Linux, macOS, and Android.
         \endlist
         \li \l {Qt Network Authorization}
