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).
