Tesla doesn't completely redesign its models or officially refresh them. CEO Elon Musk has actually insisted on this even though vehicles like the Model S underwent a facelift and the Model S and Model X are now available as new "Raven" models.
With the said, Tesla's vehicles are changing on an almost constant basis due to over-the-air software updates and periodic hardware upgrades. The Model X came to market in September of 2015 and has changed significantly since its release. While it doesn't look much different, it's a different car in a number of ways.
