MAJOR In the multi-location inventories service we have added an import mechanism to allow bulk setting of stock positions. This feature allows for simpler synchronization between the inventories service and customer's own stock management systems.
See Imports.
MAJOR In Product Experience Manager (PXM), we have introduced a new feature to allow stock to be managed in multiple locations
Multi-location inventories allow more flexibility in managing stock which enables scenarios such as Buy Online, Pick Up In-Store. This change has changed the format of requests and responses to the inventories service and to avoid any breaking changes has not been applied to existing stores that use this service.
