  0.4.10 (to be announced) "heterogeneous vacuum"
  -----------------------------------------------
  
 +      - The --no_default_filters option of para_filter has been
 +        depricated. It still works but has no effect and will be
 +        removed in the next version.
 +      - Cleanup and consolidation of the various wrappers for
 +        write(), writev(), send() and friends.
 +      - The obscure error messages on mmap() failures have been
 +        replaced by meaningful messages. This affects mainly
 +        para_afh.
++      - para_audioc: Cleanups and memory leak fixes.
 +
  -------------------------------------
  0.4.9 (2011-12-06) "hybrid causality"
  -------------------------------------
