Until the Staff have the source code back in their hands, there's no way for them to change, update, or modify the game. If KovuLKD (the creator of Feralheart) decides to hand over the source code to one of the Administrators, then the Staff would be able to update the game. Until then, however, the only sort of game update includes modifications, markings, and items that other people have created. Although the game itself isn't able to be updated at the time being, the Staff are consistently arranging events inside and outside of the game.
We don't know when the next official update will come. All we can do now is enjoy how the game as grown thus far, and hope for the best in the future.
