  • IMP: The update notification was improved 
  • IMP: Optimizations have increased the computing speed (up to a factor of 2)
  • FIX: Display errors fixed where selections were not plotted correctly
  • FIX: The opening of documents of older program versions improved
  • FIX: The activated table type is now taken into account during saving/loading
  • FIX: Various minor bugs of the user interface have been fixed
  • FIX: Fixed the bug that the program did not always recalculate when the slider was moved
  • FIX: Misleading message in case of no longer defined sizes in a self-defined table corrected
