Breaking Changes

  • font mechanism has changed to include a new FontFamily concept, and code that makes or inherits font types may need to be changed.
  • itemString was changed from 12 to 13 parameters with addition of specializationID in the middle. (in 6.2.0)


  • .xsd is still missing 'relativeKey' on Anchor


  • XML/Script 'inherit' attribute, for automatically pre/post hooking inherited scripts
  • XML/Font 'height' attribute, as alternative to <FontHeight> Value element. Takes precedence over FontHeight. Does not exist on FontString. Must set 'font' for 'FontHeight' or 'height' to be used.
