I dont think they will update more "progress" in this page because its the "DEMO", pretty much they will create a steam page or a new page here for the full game. (Just my guess).
Yeah, thank you for your answer and I know that's a thing... But I have a notification in my feed that states they actually DID updated the "DEMO" four days ago, and since I played it like a week and a half ago, I would like to know if they changed something worth downloading it again. That's why I think they should add an update log, only IF they are going to keep updating the demo... That's all. At least if there's something actually new in it. Otherwise we should just ignore the notifications.
