FFADO 2.4.2 released

The FFADO project is pleased to announce FFADO version 2.4.2.  This is a bug
fix release which mainly addresses some lingering issues associated with
python3.  While most of the fixes relate to the build process, one could
affect the mixer GUI at runtime.

FFADO 2.4.2 is a source-only release which can be downloaded from the
project's website at http://ffado.org/, or directly from

    http://ffado.org/files/libffado-2.4.2.tgz.

Thanks to those who contributed towards this version: Jinke Fan, Hector
Martin, Orcan Ogetbil, David Runge and Jonathan Woithe.
