The newely introduced parameter
Billing|DeliveryAddressForm.AddressSource parameter now has a default Value of
NONE. This means, that, per default, no address will be gathered, be it through Saferpay, or the payment method! You must keep this in mind, if you gather your customers address through Saferpay, or the payment method (e.g. PayPal). Likewise the parameter
Billing|DeliveryAddressForm.Display no longer exists and is replaced by AddressSource.
