I'm only seeing one of these new files available to download: Dwarf ID Extra Sheets. The other two don't show up for me when I go to my download page for this game. I'm a Kickstarter backer, so my copy is "claimed". IDEK if that has something to do with it.
Dwarf Generator Supplement Available Now
Just for fun, I've put together a little Dwarf ID minizine that gives you names, jobs, and unique traits that you can use to generate character sheets for your various dwarves. It doesn't have to just be soldiers and gunners and the likes either, no, your fortress has plenty of unsung heroes and money grubbing louts in it so why not use these IDs to inject some life and character into the hold.
You can find it in the files section :)
