Qt 6.11 is now available with several major additions. A new Qt Canvas Painter module brings hardware-accelerated 2D rendering built on Qt's RHI, offering significant performance gains over QPainter's OpenGL backend and following the HTML Canvas 2D API. Qt Quick 3D gains real-time rendering techniques including Screen Space Global Illumination (SSGI), Screen Space Reflections (SSR), per-object motion vectors, and advanced render-pass customization via new QML APIs. The Qt Graphs module adds multi-axis support for 3D graphs, a new CustomSeries type, and a Wind Turbine Dashboard example. A new Qt TaskTree module (technology preview) introduces a declarative approach to asynchronous C++ workflows. Other improvements include Lottie/SVG animation enhancements, a new DoubleSpinBox in Qt Quick Controls, an OpenAPI code generator for Qt HTTP clients, gRPC flow control improvements, better QML/C++ IDE navigation, and Android Java/Kotlin interop enhancements.
