Qt 5.12.4 is a bug-fix release. It maintains both forward and backward
compatibility (source and binary) with Qt 5.12.0 through 5.12.3.
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.
Some of the changes listed in this file include issue tracking numbers
corresponding to tasks in the Qt Bug Tracker:
https://bugreports.qt.io/
Each of these identifiers can be entered in the bug tracker to obtain more
information about a particular change.
****************************************************************************
* General *
****************************************************************************
- The qtimageformats module now offers configuration settings
available in the global Qt configure. The image format handlers
based on external codecs can be enabled or disabled, and the choice
between bundled and system codec library can be set.
