The new options might not be noticeable to Facebook users right away. On mobile, they'll be hidden within the Like button: you'll have to press and hold Like for a moment before the new options — which Facebook calls "reactions" — pop up. From there, you can select one of the five new options, each of which is represented by a cute animated image. There was originally going to be a sixth option — "yay" — but Bloomberg says that Facebook removed it at some point over the past few months after determining that it wasn't "universally understood." You can read more about how Facebook created its new reactions feature in our story from when it was first announced. Bloomberg also has a nice profile on one of Facebook's leaders that discusses the new feature's development.
