| **************************************************************************** |
| * Important Behavior Changes * |
| **************************************************************************** |
| |
| - [QTBUG-76521] RCC's default compression algorithm was changed back to |
| Zlib, as it was in all previous releases until 5.13.0. The default will |
| remain Zlib for all Qt 5.x releases but will change in Qt 6.0. To |
| activate Zstd compression for your resources, either pass the |
| --compress-algo=zstd option to the rcc tool or add the XML attribute |
| compression-algorithm="zstd" to the <file> tags in the .qrc file. |

| |
| - [QTBUG-76293] Fix NDK r20 linking. |
| |
| **************************************************************************** |
| * QtCore * |
| **************************************************************************** |
| |
| - Global: |
| * [QTBUG-72073] Added the QT_NO_FLOAT16_OPERATORS macro in order to work |
| around a Microsoft <= VS2017 compiler bug that is exposed when using |
| std::bitset along with any Qt header that includes <qfloat16.h>. |
| |
| - QCborStreamReader: |
| * Fixed a bug that caused the QIODevice that the data was being read |
| from not to show the entire CBOR message as consumed. This allows the |
| user to consume data that may follow the CBOR payload. |
| |
| - QDeadlineTimer: |
| * [QTBUG-69750] Fixed integer overflows leading to immediate timeouts. |
| |
| - QStorageInfo: |
| * Fixed a bug that caused QStorageInfo to be unable to report all |
| filesystems if the options to mounted filesystems were too long (over |
| 900 characters, roughly), such as those found in Docker overlay |
| mounts. |
| |
| - QTextBoundaryFinder: |
| * Sentence breaking now no longer breaks between uppercase letters and |
| comma. This is a deviation from the Unicode specification, but |
| produces less surprising behavior. |
| |
| - QTimeZone: |
| * The IANA timezone database backend now properly follows symlinks even |
| when they point to variable locations like /run or /var (useful when |
| /etc is mounted read-only). |
| |
| - QVector: |
| * Fixed a regression that caused fill() not to detach, corrupting shared |
| copies. |
| |
| **************************************************************************** |
| * QtNetwork * |
| **************************************************************************** |
| |
| - Windows: |
| * Correctly emit errors when trying to reach unreachable hosts or |
| services |
| |
| - QNetworkAccessManager: |
| * Fixed QNetworkAccessManager::sendCustomRequest for Qt For WebAssembly. |
| |
| **************************************************************************** |
| * QtGui * |
| **************************************************************************** |
| |
| - [QTBUG-73231] QWindow::mapToGlobal()/mapFromGlobal() now handle windows |
| spanning screens correctly. |
| |
| - QImage: |
| * Improve loading time when loading png files that have the same size as |
| the target. |
| |
| - QPixmapCache: |
| * [QTBUG-76694][QTBUG-72523] Ignore unsafe access from non-main threads |
| |
| - Text: |
| * [QTBUG-76219] Fixed a bug which could cause the font cache to grow |
| larger than it was supposed to. |
| * [QTBUG-55096][QTBUG-74761] Fixed bug where regular text rendered with |
| a color font would always display in black. |
| |
| **************************************************************************** |
| * QtWidgets * |
| **************************************************************************** |
| |
| - QSystemTrayIcon: |
| * On macOS, show the icon passed into showMessage in the notification |
| popup |
| |
| - QDateTimeEdit: |
| * Use the information provided by the locale to determine the AM/PM |
| strings, unless they are already translated. |
| |
| - QGraphicsView: |
| * Ignore disabled items when setting the mouse cursor. |
| |
| - QMenu: |
| * Shortcuts are again shown by default in context menus, except on |
| macOS. They can be forced off by setting |
| AA_DontShowShortcutsInContextMenus to true. |
| |
| - QSplashScreen: |
| * On macOS, lower the splash screen when a modal dialog is shown to make |
| sure the user sees the dialog. |
| |
| **************************************************************************** |
| * Third-Party Code * |
| **************************************************************************** |
| |
| - Updated bundled SQLite to version 3.28.0 |
| - Updated QLocale's data to CLDR v35.1 |
| |
| **************************************************************************** |
| * qmake * |
| **************************************************************************** |
| |
| - [QTBUG-75653] The CONFIG value c++latest was added to select the latest |
| C++ standard the currently used toolchain supports. |
