++ Qt 5.4.1 is a bug-fix release. It maintains both forward and backward
++ compatibility (source and binary) with Qt 5.4.0 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:
++
++
++ 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 is no longer binary compatible
++ with Qt 5.4.0 when using either of those compilers.

++ /opt/local/lib
