Thank you for the explanations. And yes that reply answered my questions. I do think that a game having a new major version out is worthy of being bumped up in the ranking but it is what it is.
The only thing I will point out is that my dev blog beside link for patreon have a screenshot showing what new content is added to the game in terms of images/animations/words, those are the main things players want to see in terms of dev blog/changelog about game updates (for a VN). But in the same time yes it could be better if I have added text with more details about the update, beside the information already on project page, and that's something to improve for the future.
And on "butler" the main reason at least for me to avoid it is the 1gb limit which the game will eventually reach (then I have to manually request more space) and obviously its convenient to just drops the links I already have uploaded for the patreon page. But switching to butler is something to think about in the long term, its just not a high priority right now.
