| * Important Behavior Changes * |
| **************************************************************************** |
| |
| - [QTBUG-14769] TextEdit now uses the I-beam cursor by default, and the |
| pointing hand cursor for links. However in C++ it's still possible to |
| override with a custom cursor. |
| - [QTBUG-70826] The QML Runtime tool now has an updated application icon |
| and a default window icon. QtQuick applications can still use |
| QWindow::setIcon() to override the window icon. |

| |
| - [QTBUG-75880] An anonymous function's "name" now comes directly from the |
| surrounding object pattern if applicable. This fixes some ecmascript tests |
| where functions were assigned to the key "eval" in an object. |
| - [QTBUG-75896] Fixed lookups of properties in QML singletons. |
| - [QTBUG-48809] We now print a warning when encountering a non-relative URL |
| in a qmldir file. You should use relative paths. |
| - [QTBUG-75609] Improved the cache for looking up attached properties objects, |
| to fix a performance regression in Qt Quick Layouts. |
| - [QTBUG-75392] Fixed a crash caused by std::function. |
| - [QTBUG-74048] Fixed a crash in QJSEngine::evaluate. |
| - [QTBUG-75501] lupdate now works better with the Qt Quick compiler. |
| - [QTBUG-75393] Fixed debugging of named signal arguments in Connections. |
| - [QTBUG-75410] Fixed maximum call stack depth for clang ASAN builds. |
| - [QTBUG-74815] We now allow creation of variants from non-singleton |
| QQmlTypeWrappers. |
| - [QTBUG-74815] Unknown types are no longer mis-identified as "null". |
| - [QTBUG-75335] Fixed a crash related to optimized heap lookups. |
| - [QTBUG-73217] The "QML debugging is enabled" warning is printed |
| normally rather than via a log message, which works better with |
| static builds. |
| - [QTBUG-75176] Fixed a crash on exit related to attached properties |
| on static builds. |
| - [QTBUG-75203] Fixed a crash when accessing invalid properties through |
| QObjectWrapper |
| - [QTBUG-71116] Errors in fetchOrCreateTypeForUrl are no longer fatal. |
| - [QTBUG-75121] Fixed an invalid capture in ECMAScript |
| string.replace(RegExp, backref) |
| - [QTBUG-74876] Fixed a crash in LinkBuffer's performFinalization. |
| - [QTBUG-74876] Fixed a memory leak when emitting QImage or QPixmap |
| as a signal argument. |
| - [QDS-589] qmlscene now supports file selectors. |
| - [QTBUG-74867] We now detect and reject cyclic aliases to avoid |
| infinite recursion. |
| - [QTBUG-74884] Configuration with -no-feature-delegate-model now works. |
| - [QTBUG-75030] Fixed an arithmetic exception related to bindings. |
| |

| |
| - [QTBUG-73768] Fixed a failing assertion in BorderImage when any border size |
| exceeds source image size. |
| - [QTBUG-75770] MouseArea no longer mis-identifies fast drags as double clicks. |
| - [QTBUG-75002] Accessibility: StaticText nodes are now properly marked as |
| read-only. |
| - [QTBUG-70083] Replaced PinchHandler qCInfo messages with qCDebug. |
| - [QTBUG-70083] Fixed the "no points" warning when using native gestures. |
| - [QTBUG-73182] Fixed a memory leak by optimizing storage of |
| QQuickEventPoint instances. |
| - [QTBUG-65761] Fixed input handling in QWebEngineView on eglfs. |
| - [QTBUG-51993] Canvas3D now works properly inside QQuickWidget. |
| - [QTBUG-74966] DragHandler no longer makes its target jump if you |
| start dragging in the margin area. |
| - [QTBUG-74679] Touch cancel now results in an ungrab event, so that |
| any parent flickable can filter the event, reset its state and be ready |
| to scroll again. |
