===> Important Fontconfig configuration change <===

  The way fontconfig is configured has been changed. 
  Configuration is done via /etc/fonts/conf.avail and conf.d.
  Read /etc/fonts/conf.avail/README for more information.

  Configuration via /etc/fonts/local.conf is still possible,
  but is no longer recommended for options available in conf.avail.
