+****************************************************************************
+* Library *
+****************************************************************************
+
+QtMultimedia
+------------
+
+ - Added QAbstractVideoFilter that serves as a base class for QML
+ video filtering elements that integrate compute, vision, and image
+ processing frameworks with VideoOutput.
+ - Added new QCameraViewfinderSettings class.
+ - [QTBUG-40571] Fixed memory leak in QAudioDecoder.
+
+ - Camera (QML):
+ * Added imageProcessing.colorFilter, viewfinder.minimumFrameRate and
+ viewfinder.maximumFrameRate properties.
+ * Added new supportedViewfinderResolutions() and
+ supportedViewfinderFrameRateRanges() methods.
+ * Exposure modes extended to support Action, Landscape, NightPortrait,
+ Theatre, Sunset, SteadyPhoto, Fireworks, Party, Candlelight, and
+ Barcode modes
+
+ - QCamera:
+ * Added support for viewfinder settings. In addition to the getter and
+ setter, supportedViewfinderSettings(),
+ supportedViewfinderResolutions(), supportedViewfinderFrameRateRanges()
+ and supportedViewfinderPixelFormats() can be used to query for
+ supported values.
+ * Fixed searchAndLock() and supportedLocks() functions which could not
+ work at all on some platforms.
+
+ - QCameraExposure:
+ * Exposure modes extended to support Action, Landscape, NightPortrait,
+ Theatre, Sunset, SteadyPhoto, Fireworks, Party, Candlelight, and
+ Barcode modes
+

+ * Added support for color filters.
+
+****************************************************************************
+* Platform Specific Changes *
+****************************************************************************
+
+Android
+-------
+
+ - Added support for additional camera exposure modes (see list in
+ QCameraExposure changes).
+
+iOS / OS X
+----------
+
+ - Improved camera support:
+ * 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.
+ - [QTBUG-37655] Fixed video capture on iOS.
+ - [QTBUG-39240] QMediaPlayer and the QML Audio and Mediaplayer types now
+ support volume and mute on iOS 7.0 and later.
+ - [QTBUG-42035] Fixed crash when capturing an image after changing the
+ active camera device.
+
+Linux
+-----
+
+ - Added support for GStreamer 1.0. The 0.10 series is still used by default
+ and Qt needs to be configured with '-gstreamer 1.0' to enable 1.0
+ support. If only GStreamer 1.0 is available on the system, the configure
+ 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
+-----
+
+ - [QTBUG-42263] QMediaPlayer and the QML Audio and Mediaplayer types can
+ now play media files stored in a Qt resource file.
+ - [QTBUG-44838] Fixed camera preview on Lumia 630.
+ - [QTBUG-45920] Fixed camera preview on Lumia 530.
