+Qt 5.5 introduces many new features and improvements as well as bugfixes
+over the 5.4.x series. For more details, refer to the online documentation
+included in this distribution. The documentation is also available online:
+
+  http://doc.qt.io/qt-5.5
+
+The Qt version 5.5 series is binary compatible with the 5.4.x series.
+Applications compiled for 5.4 will continue to run with 5.5.
+
+Some of the changes listed in this file include issue tracking numbers
+corresponding to tasks in the Qt Bug Tracker:
+
+  http://bugreports.qt.io/
+
+Each of these identifiers can be entered in the bug tracker to obtain more
+information about a particular change.

+****************************************************************************
+
+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
+
+ - QCameraImageProcessing:
+   * 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.
+ - [QTBUG-45667] Fixed crash that could occur when using the camera
+   preview.
