+
+Android
+-------

+   QCameraExposure changes).

+   * Image capture settings, focus, flash, exposure (iOS only) and
+     zoom (iOS only) APIs are now functional.
+   * QVideoProbe can now be used with a QCamera.
+
+ - VideoOutput, when used with a MediaPlayer on iOS, can now be displayed
+   under other elements and supports shader effects and advanced
+   transformations.
+ - QMediaRecorder now uses the correct system default audio capture
+   device.
+ - [QTBUG-36175] QMediaPlayer and the QML Audio and Mediaplayer types can
+   now play media files stored in a Qt resource file.

+   script will automatically configure Qt with GStreamer 1.0 support.
+ - QCamera now supports exposure and white balance locks.
+ - Added support for additional camera exposure modes (see list in
+   QCameraExposure changes).
+ - Fixed QCameraImageCapture::supportedResolutions(),
+   QMediaRecorder::supportedResolutions() and
+   QMediaRecorder::supportedFrameRates() that could return empty lists.
+ - [QTBUG-46169] QVideoWidget now works with any windowing system. It was
+   previously only working with X11.
+
+Windows
+-------
+
+ - [QTBUG-45571] QAudioBuffer::startTime() now returns the time in the
+   correct time scale.
+
+WinRT
