Changelog / Release Notes
Version 6.0.0 (2025/12/25)
Note that WPSSO WCMD requires WooCommerce 9.2+.
Removed the "GTIN" input field as WooCommerce 9.2+ offers a new "GTIN, UPC, EAN, or ISBN" input field. The MPN, ISBN, GTIN-14, GTIN-13 (EAN), GTIN-12 (UPC), and GTIN-8 input fields from the WPSSO WCMD add-on are still preferred, as they allow for multiple globally unique IDs (not just one) to be included in the Schema Product markup. You can enable all WPSSO WCMD input fields from the SSO > WC Metadata settings page.
