+****************************************************************************
+* QtQml *
+****************************************************************************
+ - [QTBUG-83384] Fixed various failing assertions in the JIT compiler.
+ - [QTBUG-85605] QQmlObjectCreator: fixed member func call with this == nullptr
+ - [QTBUG-84104] Fixed a regression in QMetaType::registerConverter()
+ with converting JS arrays to sequence<T> types.
+ - [QTBUG-84447] Invokable methods of Q_GADGET objects are now fully accessible.
+ - [QTBUG-84095] Fixed an invalid memory read in QQmlContextData::emitDestruction()
+ - [QTBUG-84692] Fixed a race condition in QQmlData::createPropertyCache
+ - [QTBUG-84237] Fixed a bug which prevented inline components from accessing
+ inner objects in some cases.
+ - [QTBUG-83121] QQmlEngine::baseUrl() no longer returns an empty url
+ if the current path is the root directory.
+ - [QTBUG-83214] Fixed a memory leak in a StateMachine with signal handler.
+ - [QTBUG-84474] On all platforms other than Windows, QTimeZone::systemTimeZone()
+ is now used when converting from times such as QTime(0, 0, 0), to avoid
+ incorrect daylight-saving accounting in the BST timezone.
+ - [QTBUG-83352] Fixed a crash caused by QQmlDelegateModel items being
+ deleted while being removed from the cache.
+ - [QTBUG-83354] We now warn about circular dependencies between QML types while loading.
+
+ - qmlformat tool:
+ * [QTBUG-85321] Fixed handling of empty blocks.
+ * [QTBUG-85035] Nested functions no longer get moved to the top level.
+ * [QTBUG-85077] Braces are no longer removed from nested if's.
+ * [QTBUG-85003] Fixed the trailing newline in if blocks so that the
+ formatting is stable during repeated runs.
+ * [QTBUG-85189] Inline components are now formatted correctly.
+ * [QTBUG-85289] Bindings that take up multiple lines are now formatted correctly.
+ * [QTBUG-84599] String literals are not reformatted: thus unicode
+ escape sequences are now preserved.
+
+ - Qt Quick Compiler:
+ * [QTBUG-85243] Revived QTQUICK_COMPILER_SKIPPED_RESOURCES for cases when
+ some resources should not be compiled with qmlcachegen.
+ * [QTBUG-84901] Fixed compilation from a different drive on Windows
+ by converting the colon after the drive letter to an underscore.
+
+****************************************************************************
+* QtQuick *
+****************************************************************************
+
+ - Accessibility:
+ * [QTBUG-83738] Fixed a crash when the Accessible attached property was
+ accessed on ApplicationWindow or another non-Item object.
+ * [QTBUG-82433] Screen readers (such as Windows Narrator) no longer
+ spell out the characters in TextInput { echoMode: TextInput.Password }
+
+ - AnimatedSprite:
+ * [QTBUG-63942] AnimatedSprite now resumes playback when it becomes
+ visible again, if it was playing when it was hidden.
+
+ - Event Handlers:
+ * [QTBUG-85303] In a HoverHandler with a margin and a cursorShape, the
+ cursor now changes within the margin area.
+
+ - Flickable:
+ * [QTBUG-31905] With AutoFlickDirection and AutoFlickIfNeeded,
+ we now take margins into account to avoid unnecessary scrolling.
+
+ - Item:
+ * [QTBUG-55879] grabToImage() now works with QQuickRenderControl.
+ * [QTBUG-40220] If polish() is called within updatePolish(), or a polish
+ loop occurs for some other reason, the detection is now more correct, and
+ the warning occurs after 1000 such loops. The loop is broken after
+ 100,000 times, to avoid the application becoming unresponsive.
+
+ - Item views:
+ * [QTBUG-82989] Since the parent of a delegate can end up being null during
+ its lifetime, developers are now advised against using it in bindings.
+ * [QTBUG-83956] TableView now allows negative spacing, which is useful
+ to cause delegates with borders to overlap and make a single-pixel grid.
+ * [QTBUG-84046] During layout, TableView now sets item width before height.
+ This works better with text items like TextEdit which calculate implicit
+ height based on the assigned width, (because of word-wrap.
+ * [QTBUG-84604] Fixed a culling regression when using ListView with ObjectModel.
+
+ - Layouts:
+ * [QTBUG-71839] Performance improvements to Qt Quick Layouts. This has the
+ small side-effect that size hint (implicitWidth/implicithHeight etc)
+ changes are not immediately emitted after a layout has been modified.
+
+ - MouseArea:
+ * [QTBUG-82382] Dragging can no longer be started with non-accepted mouse buttons.
+ * [QTBUG-85111] Fixed a regression in mouseX/mouseY calculations during
+ dragging of a MouseArea whose position is not 0,0.
+
+ - Rectangle:
+ * [QTBUG-84069] Named preset gradients are working again.
+
+ - Repeater:
+ * [QTBUG-83356] keyboard.left/keyboard.right navigation now works when
+ setting up navigation to Repeater-created siblings.
+
+ - RHI / scene graph:
+ * [QTBUG-85965] If the first node in a batch becomes invisible due to opacity
+ change, it now triggers rebuilding the batch.
+ * [QTBUG-85996] Fixed a crash in QSGBatchRenderer::Renderer::updateStencilClip()
+ due to clipNext being null.
+ * [QTBUG-65170] Fixed a crash when QSGTexture is deleted in rc->endSync()
+ * [QTBUG-83319] Fixed a crash in QQuickWidget when failing to make the OpenGL
+ context current in createFramebufferObject() during resizing.
+
+ - Shapes:
+ * [QTBUG-82371] Fixed a crash on eglfs.
+
+ - Window:
+ * Pass input method events on to the focus item.
+ * [QTBUG-82815] A transient Window declared in an Item which is shown via
+ QQuickWidget now becomes visible even though the parent window is offscreen.
+
+ - Text:
+ * [QTBUG-69301] Fixed Outline style on connected glyphs, especially visible
+ in e.g. Arabic and Indic writing systems.
+ * [QTBUG-85514] Fixed a regression in antialiasing on outlined text.
+ * [QTBUG-81810] Fixed a bug where we would sometimes resolve the wrong fonts
+ inside .ttc font collections.
+ * [QTBUG-49646][QTBUG-84021] Fixed kerning with horizontalAlignment: center.
+ * [QTBUG-84454] Fixed an offset on text position when combining
+ NativeRendering with high-dpi scaling.
+ * [QTBUG-80180] Fixed a clipping bug in software-rendered text.
+ * [QTBUG-83819] If the selection color is transparent, it is not
+ rendered, to avoid problems with blending.
+ * [QTBUG-84981] Fixed the vertical alignment of images in a text document
+ to align with the HTML standard as much as possible: AlignMiddle
+ is between AlignTop and AlignBottom.
+ * [QTBUG-84351] Optimized text glyph geometry updating by doing it
+ only when necesssary rather than in scene graph preprocessing.
+
+****************************************************************************
+* Platform Specific Changes *
+****************************************************************************
+
+ - [QTBUG-84497] Fixed build issue on Windows when using nmake
+ (RegExpJitTables.h was not generated correctly).
+ - [QTBUG-83115] On webOS, Images with the same source are now shared even if
+ the cache property is false.
+ - [QTBUG-83119] On webOS, synthetic hover events are no longer sent on
+ frame update.
