The next major version is 0.10.x, just keep in mind that the game is considered finished by virtue of the main story being totally done. namely escaping noer island. And anything further is extra content like side quests that aren't required to meet this finished game state.
Cool and I gotta say this is the best game to ever be published by how much details is put into the game, we definitely have something big here and that is bigger than GTA6
