Is this article from 2015 or 2017?

It would be great if the page displayed the date that the article was posted/updated. It is not in the URL nor the sources. The only way to see the dates is in the RSS feed and even that is only for new articles.

Last update is _today_. It links to a comment on this thread. I think (2016) should be removed.
