Changes in Integration with WooCommerce:
• Added parameter attribute_ids for attribute.list method
• Added parameter lang_id for attribute.list and attribute.info methods. Now the values of the name and values fields will depend on the specified lang_id value
• Added field additional_fields->wpml_info for attribute.list and attribute.info methods
• Added attribute.value.add, attribute.value.update and attribute.value.delete methods.
• Fixed the product.attribute.value.set method. If the option is global, it binds the corresponding translations of the option values to the product and its translations. If you specify the attribute_name + value parameter set and there is no attribute with this name, then the corresponding attribute with translations is created and immediately linked to the corresponding product translations. If the attribute is custom, then it is linked only to the translation in the specified language, and the attribute will not be duplicated for all product translations.
