"There is going to be a Stardew 1.6 update", Barone wrote on Twitter. "It's mostly changes for modders (which will make it easier & more powerful to mod). But there is also new game content, albeit much less than 1.5. I'm taking a break from Haunted Chocolatier to work on this at the moment. Then back to [Haunted Chocolatier].
