+Qt 5.5.1 is a bug-fix release. It maintains both forward and backward
+compatibility (source and binary) with Qt 5.5.0.
+
+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
+------------
+
+ - The environment variable QT_QUICK_NO_TEXTURE_VIDEOFRAMES can now be used
+   to disable OpenGL texture based video frames when using the VideoOutput
+   QML type. This can be useful in applications that wish to filter and
+   process the video frames using QAbstractVideoFilter and are not GPU
+   based.
+ - QCamera's viewfinder capabilities functions now report correct values
+   when filtering by pixel aspect ratio.
+ - [QTBUG-46359] fixed crash after using moveToThread() on a QSoundEffect.
+ - [QTBUG-47205] fixed VideoOutput (QML) rendering frames from the wrong
+   source when having multiple VideoOutputs using different sources.
+ - [QTBUG-47630] fixed Camera.supportedViewfinderFrameRateRanges() (QML)
+   returning incorrect values when the argument is not of type 'size'.
+ - [QTBUG-47859] fixed crash when using Radio.radioData (QML) without
+   a radio backend available.

+
+Android
+-------
+
+ - Fixed QVideoProbe stopping to work when using QMediaRecorder to record
+   the camera.
+ - Video frames passed to a QAbstractVideoFilter can now be mapped to
+   system memory.
+
+Linux
+-----
+
+ - QCameraImageProcessing::isWhiteBalanceModeSupported() now correctly
+   reports if a given white balance mode is supported.
+ - [QTBUG-45707] fixed QAudioRecorder::stop() sometimes failing to
+   actually stop the recording.
+
+ WinRT
+-----
+
+ - [QTBUG-46456] QCameraImageCapture: getting the list of supported
+   image capture resolutions and setting the image capture resolution is
+   now supported.
+ - [QTBUG-47373] fixed crash occurring with some camera operations.
