We added a feature for adding and changing product identifiers such as EAN, ASIN and MPN. When viewing a product you will find a new configure icon next to the delete and duplicate icons. When clicking this icon a form will appear where you can change the values. We added a safety check to make sure your products are offline before you can change identifiers.
Previously when doing bulk edits, empty values were ignored. We changed this behavior to match with the product content edit form. When you leave the fields empty, when doing a bulk edit, the content of the selected products will be cleared.
