Yoast SEO 12.3

While some of our checks are independent of languages, Yoast SEO has special skills to adapt the various content analyses to different languages from around the world. In Yoast SEO 12.3, we’re taking the first steps to add another language to the list: Hungarian. In addition, this release features a number of enhancement and fixes. Read our 12.3 release post to find out more!


  • Adds the transition word assessment for Hungarian. Props to @9abor.
  • Includes the admin bar CSS in AMP dev mode. Props to @westonruter.
  • Shows a floating Save changes button on Yoast SEO admin pages when the normal button is not visible in the browser window.
  • Improves user input validation feedback and suggestions for error correction.
  • Introduces a new filter wpseo_sitemap_http_headers which allows filtering the HTTP headers we send for XML sitemaps.
  • Adds a RankMath post meta value importer.


  • Removes the notification that would be thrown if add-ons with a lower version number than the plugin were installed. The yoast_plugin_compatibility_notification method has been deprecated.
