Revision control
++ Qt 5.12.5 is a bug-fix release. It maintains both forward and backward
++ compatibility (source and binary) with Qt 5.12.0 through 5.12.4.
++
++ For more details, refer to the online documentation included in this
++ distribution. The documentation is also available online:
++
++
++ The Qt version 5.12 series is binary compatible with the 5.11.x series.
++ Applications compiled for 5.11 will continue to run with 5.12.

++
++ - 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).
++
++ ****************************************************************************
++ * QtGui *

++
++ - 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).
++
++ ****************************************************************************
++ * QtNetwork *
++ ****************************************************************************
++
++ - 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
++
++ ****************************************************************************
++ * Android *
++ ****************************************************************************
++
++ - [QTBUG-76293] Fix NDK r20 linking.
++ - [QTBUG-76036] Fixed an issue where menus would not work on 64 bit
++ builds.
