 ### Fixed
 - Missing label of the tx_yoastseo_prominent_word table

+- Use `websiteTitle` of site configuration within snippet preview, previously this was only taken from site languages instead of the site itself
 
 ### Changed
 - Updated mentions of the premium extension within the documentation
