2.00     2014 October 4
         Apparently I suck at version numbering. 1.0.10 is sorted as
         less recent than 1.0.9 by PAUSE. Just bumping to 2.00 and
         using more CPAN-ish versions to fix this. No other changes.
1.0.10   2014 October 4
         Fix warnings both in the upstream code and our own code,
         mainly to do with casts.
         Remove an unused call to newRV_noinc() from the "new"
         function.
1.0.9    2014 October 4
         Now includes the upstream Whirlpool.c and nessie.h
         as-is. There should be no functional changes, but this makes
         the module easier to maintain.
         Also moved the loading of the C code to BEGIN time, again,
         should have no functional changes.
         The ppport.h file was updated to the latest upstream release
         and suggested changes applied to Whirlpool.xs.
         Bump Module::Install to the latest upstream version.
1.0.8    2009 October 18
         Like 1.0.7 but with an updated MANIFEST
1.0.7    2009 October 18
         Fixed RT#50620 reported by KENTNL. The Digest.pm standard
         says that on ->hexdigest the checksum must be reset. But this
         module wasn't doing that. Oops!
1.0.6    2007 July 07
         Fixed typo in script/whirlpoolsum POD
         use utf8 for author name in Makefile.PL
         inc/: Upgraded to M::I 0.67
         Fixed release dates in release by avar, released in 2007, not 2006
1.0.5    2007 January 30
         Fixed typo in pod (oops!)
         Changed to a Module::Install-based build system
         Updated README file
         PODed INSTALL
         whirlpoolsum(1) utility
         removed examples/ directory, the Digest docs and t/ should be more than enough
         Updater ppport.h with Devel::PPPort
         Relicensed from GPL => GPL/Artistic, see COPYING for rationale.
1.0.4    2007 January 24
         - Added a clone() method that clones the state of the current object and
         - returns the cloned object.
         add and addfile now return current the object so ->add( "foo" )->digest
         works like it does in other digest modules.
         Added a b64digest method that is an alias for the base64digest method.
         Removed (add addfile reset) from @EXPORT_OK, 
         Updated the LICENSE section to the recommended FSF GPL notice
         b64digest no longer returns a trailing ==
1.0.3    2004 August 18
         Modified hashsize() to return number of bits, instead of bytes
         (to become consistent with Digest::SHA of Mark Shelor)
1.0.2    2003 July 29
         Minor code cleanup
1.0.1    Optimized even more
         Refined "files.pl" example script by including error-checking
1.0.0    2003 June 07
         Initial release
