Important behavior changes

  • Mixed content is blocked by default. To restore old behavior set QWebSettings::AllowRunningInsecureContent attribute to true
  • Now application code must handle QWebPage::fullScreenRequested signal to get fullscreen working. It's necessary because latests HTML standard specifies that any web element can go fullscreen, not only video
  • JPEG and PNG images no longer use Qt plugins (qpng and qjpeg) on Windows and macOS (actually, on any OS if Qt build uses bundled libraries)
