For more details, refer to the online documentation included in this
distribution. The documentation is also available online:

*                                  QtCore                                  *
****************************************************************************

 - 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
