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
Since I see you use git, https://github.com/git-chglog/git-chglog may be of interest -- only one of a billion tools doing the same thing, I'm sure, but I have used that successfully before. You can have it spit out a changelog from commit messages, and IIRC it was configurable enough to deliver what Factorio needs.
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.
