Hi there,
Probably you've already seen our blog post at
https://blog.x-cart.com/pa-dss-validation-for-x-payments-2-expired.html and a newsletter, but I want to post this news here, too.
Logic is similar to what we discussed at
https://forum.x-cart.com/showthread.php?t=68020 when XP 1.x PA-DSS certification expired for new deployment.
