++ QtPositioning
++ -------------
++
++ - Added QGeoShape::center() function
++ - Converted QGeoShape, QGeoCircle, QGeoRectangle & QGeoCoordinate to Q_GADGET.
++ It simplifies the integration of the above classes into QML as the extensive
++ QML value type wrapper conversion is implicitly done by Qt QML. The existing
++ custom wrappers were removed.
++ - Fixed Debug stream operators for QGeoAreaMonitorInfo, QGeoCoordinate,
++ QGeoPositionInfo, QGeoSatelliteInfo & QGeoShape following a QDebug related
++ change in Qt Base.
++ - [QTBUG-44663] Added updateTimeout() signal to QML PositionSource type
++ - [QTBUG-44983] Fixed broken build of qtlocation repo when using qmake -r
++ on OS X
++
++ QtLocation
++ ----------
