QtQuick
-------

 - Global:
   * [QTBUG-61679] Input method events now work in QQuickWidget
   * Loader and Flickable use setSize() to resize the inner Item in one
     transaction rather than setting width and height separately.
     This makes the state consistent by the time the change signals are emitted.
   * Optimized rendering of opaque pixmaps, 9-patches and layers in the
     software renderer
   * [QTBUG-61434] Fixed a crash on exit by ensuring that a PointerEvent
     instance is created only in response to an actual incoming event,
     not because of checking the mouseGrabberItem at shutdown, and by
     explicitly destroying the instances at the right time.

 - QQuickWidget:
   * [QTBUG-61798] QQuickWidget is repainted properly when moving between
     screens
   * [QTBUG-45557] Mouse enter and leave events are now correctly forwarded
     to MouseAreas inside a QQuickWidget

 - Item Views:
   * [QTBUG-62607] Fixed a crash and a memory leak related to moving Items
     in Item Views
   * [QTBUG-57225][QTBUG-57225] GridView's removeDisplaced animation
     occurs reliably and at the right time
   * [QTBUG-61269][QTBUG-62864] Changes in a ListView's model no longer
     disrupt the movement of an animated highlight item
   * [QTBUG-34576] ListView's calculated velocity remains correct during
     index-based scrolling
   * [QTBUG-63974] ListView.positionViewAtIndex now works correctly
     in the presence of sticky headers and footers

 - Platform Specific Changes:
   * [QTBUG-63835] iOS selection handles are shown properly when selecting
     all text in a TextEdit
