\title What's New in Qt 5.7
\brief Lists the new features in Qt 5.7.
\section1 New Modules
The \l{Qt Quick Controls 2} module that was previously available as a
technology preview is now a fully supported module, providing the
following features:
\list
\li A new light-weight set of embedded and mobile-oriented controls.
\li Based on a flexible template system that enables rapid development of
entire custom styles and user experiences.
\li Built-in styles:
\list
\li Default style - a simple and minimal all-round style that offers
maximum performance.
\li Material style - a style based on the Google Material Design
Guidelines.
\li Universal style - a style based on the Microsoft Universal Design
Guidelines.
\endlist
\li Can be mixed with Qt Quick Controls 1.0, but the APIs are not compatible.
\endlist
The following modules that were previously commercial-only, are now
available under GPLv3 license for the open source users:
\list
\li \l{Qt Quick 2D Renderer}
\list
\li Enables running Qt Quick applications on hardware without OpenGL.
\endlist
\li \l{Qt Charts}
\list
\li Provides ready to use controls for depicting different types
of 2D charts and graphs.
\endlist
\li \l{Qt Data Visualization}
\list
\li Enables visualizing data using 3D charts and graphs.
\endlist
\li \l{Qt Purchasing}
\list
\li Provides API to support in-app purchasing use cases with
Google Play and Apple Store.
\endlist
\endlist
In addition, the following new modules are available as technology preview
releases, enabling Qt users to provide feedback:
\list
\li \l{Qt Gamepad}
\list
\li Enables Qt gaming applications to respond to gamepad input.
\endlist
\li \l{Qt SCXML}
\list
\li Enables static and runtime integration of SCXML models into Qt code.
\endlist
\endlist
\section1 New Features in Qt 5.7
\section2 Qt 3D Module
\list
\li Added support for Compute Shaders on supported hardware.
\li Added support for loading multi-image DDS and KTX textures including
cubemaps, mip chains, and array textures.
\li Improved support for compressed texture formats.
\li Made Render surface explicit.
\li Extended Input API and support for device plugins.
\li Improved picking support.
\endlist
\section2 Qt Core Module
\list
\li Added \c qAsConst function to help using non-const Qt containers in
C++11 range for loops.
\li Enabled Qt event dispatchers to use the \c poll() function on Unix
now, making it possible for applications to have file
descriptors greater than 1024.
\li Added support for converting a floating point to its shortest and
exact string form, without having to pre-calculate the number of
digits.
\li Improved C++11 support by using \c std::atomic as backend for
QAtomic classes and adding QTypeInfo for \c char16_t and
\c char32_t.
\li Added QIODevice support for multi-streaming.
\li Enabled QPluginLoader to work even if \c QT_NO_LIBRARY is set (for
example, linking against a static libc).
\endlist
\section2 Qt Canvas3D Module
\list
\li Upgraded the \e three.js 3rd party library.
\endlist
\section2 Qt GUI Module
\list
\li Optimized QImage smooth scaling for NEON.
\li Optimized the OpenGL function wrappers for speed and code size.
The QtGui library size has been significantly reduced due to a
massive reduction in symbols.
\endlist
\section2 Qt Multimedia Module
\list
\li Added support for tvOS.
\li Extended QML playlist API.
\endlist
\section2 Qt Platform Abstraction (QPA)
\list

(instead of QQmlEngine), which allows non-QML JavaScript
debugging or profiling.
\li Added support for debugging multiple QJSEngine instances at the same
time.
\endlist
\section2 Qt Quick Module
\list
\li Added support for all subclasses of QQuickWindow by the inspector
service, which makes Qt Creator's inspection feature useful.
