What's New

Version 1.1.36:
  • Fixed a bug that could cause special outline pads to be dropped in Gerber output files if the pads are given different spacings.
  • Fixed a bug that could cause blind vias to be incorrectly saved.
  • Importing a new Text part type now simply replaces the old Text part type without creating an artifact that cannot be removed using the Prune command.
  • Fixed a bug that could cause problems when replacing parts or importing part lists if Text parts have the same name as non-Text parts.
  • Fixed a bug that could cause a crash with multiple designs windows open when closing one design window some time after a Library window has been open.


  • OS X 10.5 or later
