I can see why you would be perplexed by your own misunderstanding that people are misunderstanding anything. Pragmatically, we have no way of knowing what's supposedly apparent because you are discussing details within the game, which I'll note, we wouldn't have downloaded as people who have indicated we didn't download it. But ya know... by all means, continue making assumptions about what's apparent I guess.
A walkthrough is a guide which details the method of winning a game or the various paths available to the player. When there is only one path, there is no need for a walkthrough because the player is forced to follow the only path that exists. Since v.0.1.4, there has only been one path to follow, and only one (obvious) choice to make. Therefore, no update has been forthcoming because no walkthrough has been required since v.0.1.4. Any player who has completed the game up to the point where the current walkthrough ends (i.e. version 0.1.4) has reached that point in the game where it effectively becomes a kinetic novel.
What this means is that any walkthrough would have to cover up through v.0.1.4. That is precisely what the current walkthrough does. In other words, just use the v.0.1.4 walthrough for the latest version of the game. At some point in the future, it is likely that the game will once again have branching paths, and it will once again be useful to have an updated walkthrough. Should the fundamental parts of the game change (i.e. the programming and/or variables necessary to track the player), that would also make it necessary to update the walkthrough. Until either of those things happens, however, an update would be pointless. That is one reason why there has not been an update to this walkthrough since v.0.1.4. There may be other reasons, but we have not been told of them.
All of the above has been explained previously by various people, but not everyone reviews what has been posted before. That, and not everyone takes the time to think about what they are reading. I have attempted to provide a thorough explanation in the hope that it will provide clarity and understanding to those who actually want it. Until such time as an updated version of the walkthough is needed and/or useful, requests for an update are nonsensical. For those who have not read the thread and are therefore posting a request for an update without understanding the situation, I suggest pointing them to this post.
