Hello! I am currently using version 0.4.2, and am interested in updating to version 0.5.0, but I do not see any changelog for it explaining the update. Is this intentional? If so, do you mind sharing what's new/different with version 0.5.0?

Hiya, yeah I indeed forgot to write the changelog, and it'll be uploaded retroactively with the next minor release. For now, the changes are:
- [space-age] Add "More metallurgy" setting, which adds coke to molten metal recipes.
- Adding coke to LDS casting recipe has been merged into this new setting.

Awesome, thank you!
