Yea, I would also love a changelog for each release! That would be immensely useful.

I'd like to find the optimum ratios for each various stage (sort only, hydro + sort, hydro + chem etc). Do you know if those are published anywhere?

edit: nevermind, I realized this post is for the smelting chain, not the refining chain.

Does it work if you don't use every processing step?
