What's New

Version 2.4.5:

  • Changed the name for inscription windows and the suggested names for saving inscriptions as .insc files and graphic files.
  • The delimiters between Long Count units were spaces. Now they are periods. This reflects the general convention for the notation of Long Count Dates.


  • OS X 10.6.6 or later
