API changes in Sitefinity 5.4

This article contains changes in backward compatibility in the Sitefinity CMS 5.4 release. Here you can find the following:

• Changes in the Ecommerce module

Read the whole article for detailed information about each of the changes.

The following changes were introduced:

• The AddItemToShoppingCart method of the Telerik.Sitefinity.Modules.Ecommerce.Orders.Business.IShoppingCartAdder interface requires an additional argument of type nullable Guid. The argument represents the ID of the wish list of the user. If you are not using the Wish lists feature, set the argument to null.
• The OrderCalculator class is now obsolete. The class will be removed in Sitefinity CMS 6.1. To override the calculations for the orders you have to use the IOrderCalculator interface. For more information, read Tutorial: Create a custom order calculator.
• The OrderStatistic class has been added. It allows you to keep track of the statistics of the orders. If you are doing your own custom development (e.g. a custom checkout), you have to use the OrderStatisticUpdater class to calculate statistics of an order.

The ExchangeRateServiceCalculator class is no longer static and has its name corrected.
