The update for 1.03 isn't showing on MacUpdate. I found it on the developers site and it fixes a few bugs I noticed in 1.02:
• Checksum and calm zone calculation for UPC E barcode fixed.
• PZN barcode enhanced to PZN8 (7 code digits + 1 checksum character, valid as of 2013-01-01).
• When vector-based formats (PDF, EPS) have been chosen for export, the resolution and colorspace popups are hidden to avoid irritations about these parameters.
• Japanese localization added.
