I just upgraded TC from 2.2.3 to 2.3.5. Earlier I did this:

protected override decimal CalculatePrice(ShippingMethod shippingMethod, Currency currency, Order order)
{    
     if (order.SubtotalPrice.WithVat >= 175)
     {
                return 0M;
     }

     return base.CalculatePrice(shippingMethod, currency, order);
 }

But now the signature has changed, so I cant access the order paramter?

protected override Price CalculatePrice(ShippingMethod shippingMethod, Currency currency, long countryId, long? countryRegionId, VatRate vatRate)

Is this not possible anymore or am I missing something?
