Patched PayPal Express Checkout and IPN module ... for v1.3.7

[DrByte]

Patch Issued May 10, 2007

This fix includes:

• ** NEW ** IPN module now supports PDT Payment Data Transfer, resulting in far more reliable immediate activations of orders ... leaving your site less reliant on IPN communication for regular orders not paid by echeck.
  See instructions for configuring PDT below.
  
• accented characters outside the standard english alphabet are converted before sending to PayPal IPN
• telephone number confusion for non-North American countries now resolved (IPN)
• minor tweak for mysql5 compatibility
• Express Checkout now converts Yukon Territory properly despite PayPal's incorrect province-code
• debug infrastructure improvements
• this zip now also includes the updated tpl_shopping_cart_default.php file which was updated in January to support inline display of shipping-estimator data on the shopping-cart page

NOTES:

• If you are using the IPN module, you WILL need to remove and re-install the PayPal IPN module (after recording your settings) in order to benefit from the enclosed fixes.
• You will also need to remove and re-install the PayPal Express Checkout module in order to activate the MySQL5 fixes -- whether you are using Express Checkout or not (if you're not using it, you may de-install it again after installing).
