G'day. It'd be lovely if you included a changelog for players. Factorio has a particular format that it likes, of which the best (and only, to my knowledge) documentation is here: https://forums.factorio.com/viewtopic.php?f=25&t=67140
If you use git, https://github.com/git-chglog/git-chglog may be of interest, since it can spit out that changelog format automatically from your commit messages.
Thanks! If you opt not to, of course, no stress. It is just nice to get the info in the mod update dialog in-game.
