Highlight complex words and replace them with words that are easier to understand! This feature is in beta, so we welcome your feedback!


  • Fixes a bug where the keyphrase distribution assessment errors, or fails to mark the found keyphrases in the text, when using keyphrases that include some regular expression control characters, for example brackets.


  • Sets the minimum required Yoast SEO version to 19.3.
