In the alternate universe of Austraeoh, Ponyville has changed due to the battle with Discord and the resulting chaos rift which it left in the middle of town. However, apart from that it appears that things are carrying on more or less as before.
The side story "Hiatus" depicts Gold Petals visiting Ponyville and deciding to live there. In that story, set 9-12 months after Rainbow left, there is the completed sarcophagus in the center of town, as well as a bronze memorial of the main 6 with Rainbow Dash as the figurehead. Gold Petals becomes a second apprentice to Spike and works with him and Scootaloo in the library.
