    Version 1.5.0

      Features Added

        - Licenced under ZPL 2.0

        - The value of 'default' is no longer false.

        - Better error handling

        - When expanding macros, convert 'define-slot' into neutral
          'slot' instead of 'fill-slot', so unedited slots remain
          open.
