+Qt 5.12.8 is a bug-fix release. It maintains both forward and backward
+compatibility (source and binary) with Qt 5.12.0 through 5.12.7.
+
+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:

+
+ - QLockFile:
+   * Suppressed the warning on QNX that said 'setNativeLocks failed:
+     "Function not implemented"'. There is no difference in behavior: Qt
+     will continue not to be able to apply an OS- level file lock, which
+     means the lock could be accidentally stolen by buggy software. Correct
+     software using QLockFile should not be affected.
+
+ - QXmlStream:
+   * QTBUG-47417: QXmlStreamReader does now limit the expansion of
+     entities to 4096 characters. Documents where a single entity
+     expands to more characters than the limit are not considered well
+     formed. The limit is there to avoid DoS attacks through
+     recursively expanding entities when loading untrusted content. Qt
+     5.15 will add methods that allow changing that limit.
