I just noticed that when I do a search, the results table now has three additional columns titled ° (degree symbol), relation, and suggestion. I see how these things could be useful under certain circumstances (particularly when performing a surname search or searching for a relative who you know is already connected to you). However, these columns are currently completely empty. It makes sense that it might take some time for the data to show up, but since this was never announced as far as I can tell, I want to make sure that it wasn't released by mistake.
I do have the browser extension installed, so there is a possibility that this was added by the extension. The page that lists all of the updates to the browser extension says that the most recent update was on May 1 but does not seem to mention anything about extra columns in the search results page.
