We have added the following enhancements to the add-on in this release:

* Checkout By Amazon Instant Order Payment Notification (IOPN) Integration.
* Inventory updates immediately after the order is placed.
* Separate page specifically for managing Checkout by Amazon orders.
* Ability to search Orders by Amazon Order Id in the "Amazon orders" on osCommerce admin UI.
* New Status codes for Checkout By Amazon orders to ensure that these do not clash with the custom status codes you might have already defined.
* Support for merchants to send Cart level Custom information that is stored with the order and passed on at different levels including callback and IOPN.

IMPORTANT NOTE
--------------------
Please note that order management for amazon orders on osCommerce admin UI works only if you have a HTTPS endpoint for IOPN.

THINGS TO REMEMBER
-------------------------
1. Please set the IOPN endpoint in Seller central 2 hours prior to upgrading the 2.2 Plugin.
2. DO NOT use the upgrade script (upgrade_to_2.2.php) if you modified any of the original checkout by amazon add-on files and/or tables.
