+Qt 5.4.2 is a bug-fix release. It maintains both forward and backward
+compatibility (source and binary) with Qt 5.4.1. Compatibility with Qt
+5.4.0 is also retained, except on Windows when using MSVC 2012 or MSVC
+2013. See note below.

+For more details, refer to the online documentation included in this
+distribution. The documentation is also available online:
+
+  http://doc.qt.io/qt-5.4/

+The Qt version 5.4 series is binary compatible with the 5.3.x series.
+Applications compiled for 5.3 will continue to run with 5.4 with the
+exception of on Windows when using MSVC 2012 or MSVC 2013. See note
+below.

+****************************************************************************
+*                        Important Behavior Changes                        *
+****************************************************************************
+- Restored binary compatibility with Qt 5.3.2 on Windows when using MSVC
+  2012 or MSVC 2013. This means that Qt 5.4.1 and 5.4.2 are no longer
+  binary compatible with Qt 5.4.0 when using either of those compilers.
+- [QTBUG-42594] OS X binary package: fixed incorrect linking to libraries in
+  /opt/local/lib
+- EXIF orientation is no longer applied to JPEG images on read. EXIF
+  orientation on JPEG was introduced in 5.4.0, but due to a bug the most
+  common EXIF-format (big-endian) was not working until 5.4.1. 5.4.2 restores the
+  behavior of 5.4.0 and earlier for most EXIF-tagged JPEGs.
+  EXIF orientation will be an opt-in starting with Qt 5.5.
