Support has been added for SFRA 6.0.0
Bug fixes (int_dotdigital_SFRA):
We’ve fixed some HTTP 400 errors that were being thrown on page load for guest users.
Customers (not opted-in) were being opted-in after visiting their Account page if they were present in the dotdigital account regardless of their opt-in status; this is no longer the case.
lastModifiedDateTimeis now updated after each new order so that any address changes can be synced by dotdigital
How to update
Updates are available from the official Salesforce Commerce Cloud Github repository.
