Changes for version 1.56 - 2001-03-12

  • EVERYONE SHOULD UPGRADE TO THIS VERSION
  • fixed problem parsing ISBNs without valid country codes which would cause an infinite loop. (identified by Andy Lester <andy@petdance.com>)
  • this module is now kept in a local CVS repository
  • added symbolic constants to replace magic return values. see the docs for details.
  • fixed is_valid_checksum which would issue warnings if the string was less than ten characters (identified by Adam Thompson <athompso@athompso.net>)
  • added a test.pl which still needs more tests to reach all of the code.
