Things are moving along nicely. I have a few more tests to run for Alchemy and Libraries, but so far they are working as intended. My Armorer in my current test fort is not only a metal smith, she's a dabbling wordsmith
I have also decided what to do with leathers and whatnot. Using the More Leathers method to get somewhat appropriate amounts of leather from animals, combined with several levels of tough/thick hides, I should be able to give us a more reasonable selection. Cow leather will be better than, say, deer leather for armor, while Rhino Leather will be about as good as bronze armor. Creatures like the Ironhide Centipede should also work as intended. I may add in Furs while I'm at it.
I'm also going to do a modest bit of acceleration to make all non-useful animal materials generic (sinews, nerves, blood, stuff like that). There will probably be a few exceptions for special/sentient creatures (Dragon Blood could be useful for Alchemy somehow, for example, and we generally want to know about dwarf/goblin/elf blood), but we don't really care if there is cow blood or pig blood on the ground.
Dyansauri, sadly, do not seem viable as carnivores in your basic medium world. I'm going to test them some more with larger and high savagery worlds, but as-is they become more of a remnant race. I'll probably include the carnivore version + meat plants as an option, since having remnant/savage-lands only dinosaur people is kind of flavorful. But they won't be that way by default.
After that, I think we'll be about ready for a release. Lots to do, but I'm getting there.
Any other major requests from anyone?
