you shouldnt put the changrlog as a text file in the downloable files, when there is an update of the game and you hit the update button of the itchio app on pc instead of downloading the las version it shows you the changelog becuase it is the last file you put on itchio, so you have to hit the buttton again and find the game, because you accidentaly downloaded a textfile, you culd write the changelog directly on itchio or simple upload first the changelog text and then upload the win, mac or linux version
