Important Changes qtbase 95811fba5e CMake: Make it possible to specify a debug MySQL client library If pkg-config is not used, a debug build of the MySQL client library can be specified with -DMySQL_LIBRARY_DEBUG=. The debug and release variants of the library are automatically detected. Setting MySQL_ROOT and MySQL_LIBRARY_DIR is sufficient in most cases. 2b65c4943e Fix missing text when Harfbuzz fails to shape a substring Fixed a regression which would sometimes cause text to disappear if the string contained an unmatched variation selector character. f11a9b203b QNetworkRequest: Make header parsing locale-independent Fixed a bug where certain QNetworkRequest::KnownHeaders wouldn't be recognized as such in certain locales. 08a0f332b5 PCRE2: upgrade to 10.42 PCRE2 has been updated to 10.42. 81f1611cc8 windows: Fix vertical metrics with GDI engine Fixed an issue where the line gap of some fonts would be included twice in the font's leading. db9d604357 QT_INLINE_SINCE: never inline for static Qt builds Restored binary compatibility for static Qt builds broken by the QT_INLINE_SINCE mechanism. Qt still does not guarantee BC for static build configurations otherwise. 3801ac5db5 SQLite: Update SQLite to v3.40.0 Updated SQLite to v3.40.0 4a68590fb3 QTest::WatchDog: fix missing timeout resets on test function change Fixed a bug which caused QTEST_FUNCTION_TIMEOUT to be applied to the whole test execution, as opposed to each test function. d045fe1f51 SQLite: Update SQLite to v3.40.1 Updated SQLite to v3.40.1 7b0fc393a0 Move QTypeInfo from qpair.h to qtypeinfo.h to avoid ODR violation The QTypeInfo for std::pair/QPair will now be correct even if qpair.h hasn't been included, fixing an One-Definition-Rule (ODR) violation. 02a03f28f5 QMimeDatabase: don't stat() something that isn't a local file Fixed a regression from 6.4.0 that made certain QMimeDatabase functions that inspected file contents to fail on Unix systems, if the file was not a native file (e.g., a Qt resource). 7dddb9df64 Update bundled libjpeg-turbo to version 2.1.5 libjpeg-turbo was updated to version 2.1.5 8bb9290b72 QVarLengthArray: clear() is not resize(0) clear() no longer requires the value_type to be default-constructible. cffe6800d1 QFileSystemWatcher/Win: remove the pre-QFileInfo path normalization Fixed a bug that prevented removePaths() from removing the root of a drive on Windows. 550ee1d752 CMake: Fix position independent code linker flags not being set Qt tools are now built with position independent code even with Unix toolchains where this is not the default, for example clang. 3e9ffad0c8 SQLite: Update SQLite to v3.41.0 Updated SQLite to v3.41.0 qtdeclarative db8c78b176 Fix missing glyphs when using NativeRendering Fixed an issue where text using NativeRendering would sometimes be missing glyphs. 2ce59cad5a QQuickTableView: change the order of row and column to modelIndex() Because of a source incompatible change in Qt 6.4.0 and Qt 6.4.1, modelIndex(column, row) has been reverted back to modelIndex(row, column), equal to how it was in Qt 6.3. This also affects modelIndex() in TableView. If the order used in Qt 6.4.1 is needed, you can set the environment variable QT_QUICK_TABLEVIEW_COMPAT_VERSION=6.4 291d3ed0da TableView: deprecate modelIndex(row, column) in favor of index(row, column) modelIndex(row, column) has been deprecated in favor of index(row, column). 4f7cda0c9f QmlCompiler: Fix coercion of undefined to float and double Converting a JavaScript value to a double or float, for example by inserting it into a typed array, now assumes JavaScript type coercion semantics. In particular, converting a value that is not actually a number now results in NaN where it previously sometimes resulted in 0. qttools 820a6a14e qdoc: Unify handling of QML types and QML value types qtconnectivity 85d04c1b SDP scanner: encode input URLs and escape XML-specific characters sdpscanner now %-encodes the URLs and escapes all XML-specific characters in them before adding the result to the generated XML output. qtwayland acd81a50 client: Fix infinite recursion with text-input-v2 Fixed a possible crash when editing a field in an item view. f8aac960 compositor: Fix crash when raising shell surface item Fixed an issue where the compositor would sometimes crash if a shell surface item was brought to front. qtimageformats beb3764 TGA Plugin: Fix reading of CMapDepth Fixed reading of TGA files with a non-zero X-origin 8a1b61e Update bundled libwebp to version 1.3.0 Update bundled libwebp to version 1.3.0 6f678f7 Update bundled libtiff to version 4.5.0 Bundled libtiff was updated to version 4.5.0 Fixes qtbase QTBUG-105046 Linker failures when building with -DFEATURE_openssl_linked=ON QTBUG-109093 tst_QWidget::optimizedResizeMove flakes on openSuSE Leap 15.4 QTBUG-108747 QTabletEvent TabletMove not sent to a QWidget without any children QTBUG-108799 [REG 6.2.4-6.3.2] Airplane emoji completely breaks text rendering QTBUG-108815 Installing qtdeclarative fails QTBUG-108908 closing QComboBox popup with Escape key also closes QDialog on macOS QTBUG-101680 MySQL plugin: QSqlQuery::prepare + exec no results when table contains JSON type QTBUG-109060 QAction() handling of text does not seem correctly documented QTBUG-109061 QAction and ampersands in text QTBUG-109240 file INSTALL cannot find "/home/qt/work/qt/qtremoteobject s_build/mkspecs/modules/qt_lib_repparser_private.pri": QTBUG-109239 file INSTALL cannot find "/home/qt/work/qt/qttools_build/ mkspecs/modules/qt_lib_linguist_private.pri" QTBUG-108677 macdeployqt tool does not copy networkinformation plugin QTBUG-108641 system tray icons in Windows 10 goes blurry QTBUG-109169 Invalid QColorTrcLut use causes unreadable text with 16-bit X11 visuals QTBUG-106634 Android examples: cmake error with cmake 3.18 QTBUG-104776 AndroidContentFileEngineIterator hangs when listing shared content with nested dirs QTBUG-109226 Rare crashes in QXcbBackingStoreImage::flushPixmap QTBUG-108440 Wrong icon picked in QMenu in multi monitor multi DPI setup (Vista style) QTBUG-107627 AndroidAssetsFileEngineHandler is broken QTBUG-107662 Android keyboard doesn't close when clicking on done QTBUG-109375 [REG.]Widgets lose their focus frame when QProxyStyle is set QTBUG-109165 No repaint when QGraphicsEffect gets destroyed QTBUG-103515 QSystemTrayIcon/macOS: Cannot quit the app when the context menu is opened by secondary click QTBUG-109400 Windows: Font Line spacing differs between Qt 5 and 6 QTBUG-99601 ios: QMAKE_PRE_LINK Gives Error :Multiple commands produce QTBUG-109449 inlining QByteArray::isNull() causes BC break on static Qt builds QTBUG-108848 iOS: Voice Control Accessibility feature breaks in iOS 16 QTBUG-106701 Crash with any QML app on external display with iPadOS 16.1 on M1 iPad QTBUG-109428 ABI broke for QJniObject::callVoidMethodV in 6.4 QTBUG-109466 QTEST_FUNCTION_TIMEOUT applies to the whole test, not per function QTBUG-108365 [REG 6.4.0 -> 6.5] Low contrast status bar in Android applications QTBUG-88652 QTEST_FUNCTION_TIMEOUT and test function limit (5 minutes) are not documented.
