Since deleting old settings files would break the games that used them, and completely replacing them with new code could also break the games that used them, I added the ability to deprecate an old settings file. To deprecate an old settings file, go to Edit mode and enter the name of another settings file to redirect new invitations to. This will allow the settings file to be used when viewing games already played using it, but it will direct new invitations to the preferred settings file. This is useful when you change the rules or setup of a game or when you program a game in a way that will not work with notation used when previously playing the game with another settings file.
