+     to contentItem.children or contentItem.childrenRect.
+
+ - QQuickView:
+   * Set the window's contentItem as the QObject-parent of the rootObject
+     to ensure consistent behavior for calling findChildren() on
+     QQuickWindow::contentItem and QQuickView::rootObject.
+
+- QQuickWidget:

+
+ - TestCase:
+   * [QTBUG-61297] Fixed compare() for URL objects.

+     milliseconds differ.
