Eric Barone, aka ConcernedApe, has been hard at work on Stardew Valley. The game is still receiving updates, even though it was originally released over 8 years ago. All told, it was only a matter of time before another update was on the way. Version 1.6 has been in the works for some time.
However, it seems that the wait for the update is almost over. The creator of Stardew Valley revealed on his Twitter account that he has started working on the official patch notes for the version 1.6 update. You can see his tweet on the subject for yourself below.
