  and sad the author :-(

Version 1.73
- Minor POD changes

Version 1.72
- Changed Makefile.PL version check

Version 1.71
- Fixed validation for constructor arguments

Version 1.7
- Substancial changes in the internal structure to allow more efficient
  object destroying: now the objects that uses OOTools get destroyed always
  when they go out of scope instead in global destruction phase
- The variable related with the accessor is not tied anymore: this allows to
  bypass the options and frees object self reference that delayed the
  destruction until the global destruction phase (i.e. when the script exits).

  as plain string instead the usual hash reference
