Property sets feature in the Google Search Console enhancements expands to cover more reports. Property sets, which was launched in May this year, show how a business is seen by Google across separate websites or apps.
Additionally, you can also monitor your site’s hreflang setup across different versions of the same website during a planned transition, such as when you move from HTTP to HTTPS, or change domains.
