Feature highlights

• Qt Safe Renderer Monitor
  • With QSR 2.0, we introduced a brand new module to called Qt Safe Renderer Monitor. It is designed and implemented under MISRA-C to ensure the integrity of display content for safe items. For more detail, you can find out the details from https://www.qt.io/blog/qt-safe-renderer-monitor and https://www.qt.io/blog/qt-safe-renderer-monitor-debugging-the-safety-application
  • 
• Rendering output verification for Qualcomm Snapdragon SA8155P
  • We have added explicit support for Qualcomm Snapdragon chip sets, so that the onboard Display processor unit (DPU) CRC calculation is used for output verification. On how the Output Verification is achieved, see https://doc.qt.io/QtSafeRenderer/qtsr-outputverification.html 
• Localization support
  • With location support, developers can conveniently design, implement, and verify safety-critical user interfaces for many languages. The localization support also works with Qt Safe Renderer Monitor, so the verification of the display content output applies also to needed locales. You can read more from https://www.qt.io/blog/create-safe-uis-for-global-use
    
• Compliance with WCAG 2.1 guidelines
  • We have added the new fillColor feature, which provides a solid background color for Safe QML elements. This ensures visibility and readability by checking contrast against WCAG 2.1 guidelines. More detail can be found in https://doc.qt.io/QtSafeRenderer/qtsr-outputverification.html#using-fillcolor-property
• Safe touch support enabler.
  • We added a new API for SafeTouch, so it is possible to enable touch in a reliable way as part of the safety-critical application. You can read further from our Q&A as well as the SafeTouch API documentation

There are other improvements made in QSR 2.0, you can find the full details at https://doc.qt.io/QtSafeRenderer/qtsr-release-note.html
