NEW VERSION QBMS 1.9

(Includes important bug fix. All users encouraged to update to latest version.)

v 1.9 -- 09/05/09

- Optimized duplicate search so that large db's do not get impacted by duplicate handling.

- New feature to provide better error reporting to customers. Denials vs. validation now recognized and handled separately.

- New code to check for and handle duplicate transactions from QBMS. If same customer with same sales amount submits within 5 minutes, QBMS treats as "duplicate" and does not post the charge. BUT Zen was receiving the "OK" status and creating the order. New code checks the returned transaction ID, and if it exists - it creates an error without creating an order.

- Fix legacy bug in XML transaction request ID. This could cause transactions which submit very close together to be treated as duplicates at QBMS.
