This changes the semantics of URL redirects. Previously a redirected URL was used as the base URL for further URL resolution. This doesn't work because redirection occurs after interception and interception should not influence the resolution of further URLs. We now use the original URL as base URL for resolution of further URLs and rely on the server to redirect those, too. - [QTBUG-63844] Fixed a crash in QMetaObject::activate() when using a Loader to load items with animations QtQuick ------- - QQuickWindow: * Added logging category qt.quick.window.transient to check detection of transient windows declared inside other Items and Windows - QQuickWidget: * [QTBUG-64241] Synthesized mouse events delivered via QQuickWidget have QMouseEvent::source() set so they can be identified as synthesized * [QTBUG-64548] Shortcut now works in QQuickWidget * Fixed coordinate transformation in QInputMethodQueryEvent as delivered to QQuickWidget - Input Handling: * [QTBUG-53036] When an application is deactivated (applicationState() is no longer ApplicationActive), it's treated the same as window deactivation. Thus on mobile devices MouseAreas no longer get stuck in pressed state, etc. * [QTBUG-61144] Fixed the regression that when a mouse-handling Item or Control is used in a Flickable with a pressDelay, the delegate item did not receive touchscreen taps (in the form of mouse clicks) * [QTBUG-63026] Flickable no longer jumps when reversing the direction of scrolling on a pixel-delta-capable trackpad * [QTBUG-64249] When pressing one MouseArea via mouse, then tapping another via touch, then releasing, the first MouseArea correctly gets released - Item Views: * [QTBUG-46488] Refilling is restarted when necessary due to changing the model in a delegate's Component.onCompleted() * [QTBUG-50992] Fixed a bug which caused Qt Quick Controls to often be "destroyed during incubation" during asynchronous creation * [QTBUG-54859] Fixed a crash when items in a Repeater are moved around during asynchronous creation * [QTBUG-61537] Fixed incorrect delegate geometry due to model changes during delegate creation * [QTBUG-62864] Fixed incorrect ListView and GridView highlight position while scrolling through delegates backed by a lazy-loading model * [QTBUG-63743] Fixed a bug with clipping of items in a ScrollView - Other: * [QTBUG-62913] AnimatedImage.frameCount now has a NOTIFY signal * [QTBUG-65156] Fixed a memory leak by releasing textures during resizing
