New Features (within existing modules)

  • Qt Core
    • Added at(), operator[], mid(), right() and left() to QLatin1String
  • Qt GUI
    • QTouchEvent no have uniqueId and rotation
    • Support for dithering when converting to all QImage formats
    • Previously private QOpenGLTextureBlitter API is made public, to help QtWayland in particular
  • Qt Quick
    • Modularized the Qt Quick scene graph in order to decouple from OpenGL
    • Integrated the software backend (previously known as the Qt Quick 2D Renderer)
    • Partial update support in the software backend (2D Renderer) to prevent expensive fullscreen updates when only small areas are changing
    • Added an experimental Direct3D 12 backend
    • Implemented caching of code and data structures generated from .qml/.js files to disk to reduce start-up time and memory consumption. The resulting .qmlc and .jsc cache files are memory mapped.
    • Cleaned up touch and mouse event delivery and added a new internal class QQuickPointerEvent which is used for that purpose. This is the foundation for further improvements with regards to input event handling, but does not affect any code using Qt Quick yet.
  • Qt Quick Controls 2
    • Added new QML types: Dialog, DialogButtonBox, MenuSeparator and ToolSeparator
    • Added ripple effects to the Material style
    • Added hover effects to the Material and Universal styles
    • Added a 'System' theme to the Material and Universal styles
    • Added new experimental "platform" QML types: MenuBar, Menu, SystemTrayIcon, ColorDialog, FontDialog, MessageDialog, FileDialog and FolderDialog
  • Qt Widgets
  • Qt WebEngine
    • Based on Chromium 51+ (probably 53)
  • Qt Bluetooth
    • Bluetooth Low Energy Peripheral support on OS X and iOS
  • Qt Network
    • Support for TLS PSK ciphersuites on server side
    • Support for configurable diffie hellman parameters
  • Qt WebSockets
    • Support for TLS PSK ciphersuites on client and server side
  • Qt 3D
  • Embedded platforms
    • Enhanced multi-screen capabilities and configurability with eglfs when running on KMS/DRM, both with GBM and EGLDevice/Stream
    • Added support for 90 or 180 degrees rotation of software-rendered content (QWidget) in eglfs
