we've being contacted by a client who have advised us the Mastercard are soon to start issuing cards starting with a new number range.
We've tested this new number range on the site and it comes back with:
The card type field is required.
They're using Sagepay, EE 2.9.2 and Store 2.5.1
Is there anything we need to do to get Store to accept these new Mastercards?
