Facebook will set a cookie to keep you logged in, but it won't set one to remember whether you want to stick with a chronological News Feed. That sort of thing makes it hard to tell at a glance how old a story from a media outlet in your Feed might be. To counter that, the social network is giving certain publications access to a "breaking" tag for their posts. The bright red tag sits below a post's image and highlights how long ago it was published. Recode writes that publishers will be able to flag a story for between 15 minutes and six hours, and that it can be used once every 24 hours.
