Yoast WooCommerce SEO Premium 16.2

Bugfixes:

• Fixes a bug where not all product attributes were available in the Brands and Manufacturer dropdowns.

Enhancements:

• Adds a Yoast SEO section to the WooCommerce product data metabox that allows entering a GTIN, ISBN and MPN number.
• Analyzes the content of the short description as part of the page content.
• Throws a warning when WooCommerce is not active.
• Adjusts the wording for when Yoast SEO is not active.
• Schema:
  • Adds an @id attribute to every individual review.
  • Adds a name attribute to every individual review.
  • Adds an @id attribute to every offer.
  • Adds a productID attribute to the Product output.
  • Adds a gtin8 attribute to the Product output.
  • Adds a gtin12 attribute to the Product output.
  • Adds a gtin13 attribute to the Product output.
  • Adds a gtin14 attribute to the Product output.
  • Adds a mpn attribute to the Product output.
  • Adds an isbn attribute to the Product output. If an ISBN number is set, it double types the schema output to [ Product, Book ]. By double typing it, the Product can have the attributes of both schema.org/Book and schema.org/Product, and thus it can have an ISBN attribute and a price etc.
  • Removes the priceValidUntil attribute, as it’s not sensible.
• OpenGraph:
  • Adds a product:condition meta tag to the OpenGraph output. It defaults to new but can be filtered using the new Yoast\WP\Woocommerce\product_condition filter.
  • Adds a product:retailer_item_id meta tag to the OpenGraph output for Facebook Catalog usage.
• Don’t try to use the WooCommerce shop page in the sitemap when it is not set in WooCommerce.

Bugfixes:

• Fixes a bug where the product:brand meta tag would not always be the selected primary term.
• Fixes a bug where the product:availability meta tag would be set to instock instead of the correct in stock.
• Fixes a bug where a PHP notice would be thrown on products with variations where a variation lacked an image.
• Fixes a bug where Organization would be used in the schema output, while no organization was set.
• Fixes a bug where non-public taxonomies could be chosen as manufacturer and brand.
• Fixes a bug where the shop page would be shown in the XML sitemap when it was set to noindex. Props stodorovic.
• Fixes a bug where an empty product:retailer_item_id was output when there was no SKU.

Other:
