Changes for the Labyrinth Core
==============================

5.21    2014-04-23
        - CPAN Testers Reports from Chris WIlliams identified a very odd error
          with the installed versions of File::Temp and File::Path. Specifying
          versions of both in pre-requisites to ensure known working copies
          are installed.
        - if log file not writeable, ignore audit logging.
        - extend unformat functionality (DTUtils).
        - return (without BADACCESS) if no record found (Support).
        - allow 'charset' to be set in return headers (Writer).

          trashes some of the CGI instances of binary image files. I suspect 
          this is something to do with the data format of the image files, but
          to curtail further (already lengthy) investigations, I have written
