| - [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-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. |
| |

| some resources should not be compiled with qmlcachegen. |

| - 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: |

| changes are not immediately emitted after a layout has been modified. |
| |
| - MouseArea: |

| dragging of a MouseArea whose position is not 0,0. |
| |
| - Rectangle: |
| * [QTBUG-84069] Named preset gradients are working again. |
| |

| change, it now triggers rebuilding the batch. |
| * [QTBUG-85996] Fixed a crash in QSGBatchRenderer::Renderer::updateStencilClip() |
| due to clipNext being null. |

| 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. |
