A significant update to this add-on was made in December 2001 (unrelated to Advanced Accounting 5.1 2000-2001 updates) but there are no specific changes required as a result of the 2000 or 2001 updates. This update is available at no charge to existing Advanced Accounting 5.1-UPS interface users. For further information see http://www.addsuminc.com/ups.htm.
