Qt 5.12.3 is a bug-fix release. It maintains both forward and backward
compatibility (source and binary) with Qt 5.12.0 through 5.12.2.
For more details, refer to the online documentation included in this
distribution. The documentation is also available online:
https://doc.qt.io/qt-5/index.html
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.

****************************************************************************
* Third-Party Code *
****************************************************************************
- Changed classification of the wintab license from Public Domain to
Custom.
****************************************************************************
* QtCore *
****************************************************************************
- Event system:
* [QTBUG-72438] Fixed a possible race condition on Windows that would
cause an interrupted event loop to be stuck until more events were
posted.
- Logging system:
* [QTBUG-74359] Fixed the compilation of qCDebug("", ...) when debug
output was disabled.
- QCollator:
* [QTBUG-74209] Fixed a bug that caused QCompare to incorrect return a
sorting order on Windows if the Win32 API failed.
- QDateTime / QTimeZone:
* [QTBUG-74614] Fixed handling of timezones that contain no DST
transitions.
- QProcess:
* [QTBUG-73778] Fixed a crash when calling closeWriteChannel() on Windows.
****************************************************************************
* QtSql *
****************************************************************************
- When cross-compiling pg_config, mysql_config are not looked up in PATH
anymore. Pass -psql_config path/to/pg_config or -mysql_config
path/to/mysql_config to explicitly enable PSQL or MySQL in this setup.
****************************************************************************
* Platform Specific Changes *
****************************************************************************
- Android:
* Text fields with ImhNoPredictiveText set are no longer working around
keyboards that disregard this setting. To enforce the workaround, the
environment variable
QT_ANDROID_ENABLE_WORKAROUND_TO_DISABLE_PREDICTIVE_TEXT should be set.
* [QTBUG-74029] Added entries in the AndroidManifest.xml for specific
portrait and landscape splash screens. If one is present for the current
orientation, it will be preferred over the generic one.
- Linux:
* [QTBUG-74526] Changed the way we use the statx() system call to use a
fallback mechanism provided by the GNU C library. This should allow Qt
applications that are compiled with glibc >= 2.28 to run even on kernels
older than 4.11.
- Windows:
* [QTBUG-74062] Fixed QToolTip pop-ups and QComboBox animation pop-ups
being off by a few pixels on Windows 10.
