Unlike in any previous episode, there is a 'stinger' scene, ie. *after* the end credits are completely over.
There's a post-credit scene:
A masked stranger walking down the railroad tracks stops to see the Terminus sign Rick modified (now overgrown) and hangs his head. The stranger removes his mask to reveal that it's Morgan. He proceeds to follow a series of markings on trees (a circle with an X inside) to an unknown destination.
