The GDSN accelerator is now fully compliant with GDSN 3.1.12. For details please take a look at the "GDSN Migration Guide for version 3.1.12" documentation in the accelerator package. In case of using the food and beverage extension, please take a look at those changes as well, because there are some which could affect your current installation. Some additional enhancements include:

An XSLT transformation, which splits export files in order to have not more than 100 items in a single catalog request
The sub-entity deletion during import feature is enabled for publication status
Import mappings to import the publication status are provided (1WorldSync source only)
A pre-import step is provided which dispatches the different messages and selects a corresponding import mapping
Two new import functions
"findOrCreateCustomer"
and
"findOrCreateSupplier"
that create imported customers or suppliers in the system if they do not exist yet have been added
