All I am asking is that you post the info in the Readme before the changelog somewhere more visible (as most people redownloading a game are unlikely to think they will need to read it again).
The Readme is in the root of the game’s folder and the file is in all caps to make it stand out. The line about using previous saves is the first sentence you see when the file is opened. I have also mentioned that previous saves won’t work on a number of my weekly updates.
