Re: Updated X-Cart 4.x connector for X-Payments
> Is this update only for those who have X-Payments v2.1.1+?
No, new connectors can be used with older X-Payments versions, too, but some of the improvements can work with X-Payments 2.1.1+ only as we added new API calls there. Those who use hosted X-Payments plans can get upgrade to the latest X-Payments version absolutely free of charge by posting us a ticket about that.
