| |
| - QBitArray: |
| * Fixed two bugs that caused QBitArrays created using fromBits() not to |
| compare equal to the equivalent QBitArray created using other methods |
| if the size was zero or not a multiple of 4. If the size modulus 8 was |
| 5, 6, or 7, the data was actually incorrect. |
| |
| - 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. |
| |
| - QCryptographicHash: |
| * Fixed a bug that caused the SHA-3 and Keccak algorithms to crash if |
| passed 256 MB of data or more. |
| |
| - QObject: |
| * Fixed a resource leak caused by a race condition if multiple QObjects |
| were created at the same time, for the first time in an application, |
| from multiple threads (implies threads not started with QThread). |
| |
| - 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. |
| |
| - 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). |

| - 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. |
| * [QTBUG-69546] Fixed a crash bug in |
| QTextDocument::clearUndoRedoStacks(QTextDocument::UndoStack). |

| |
| - QHostInfo: |
| * Functors used in the lookupHost overloads are now called correctly in |
| the thread of the context object. When used without context object, |
| the thread that initiates the lookup will run the functor, and is |
| required to run an event loop. |
| |
| - Windows: |
| * Correctly emit errors when trying to reach unreachable hosts or |
| services |
| |
| **************************************************************************** |
| * QtWidgets * |
| **************************************************************************** |
| |
| - QGraphicsView: |
| * Ignore disabled items when setting the mouse cursor. |
| |
| - QSplashScreen: |
| * On macOS, lower the splash screen when a modal dialog is shown to make |
| sure the user sees the dialog. |
| |
| - QSystemTrayIcon: |
| * On macOS, show the icon passed into showMessage in the notification |
| popup |
