Here's a patch to add a basic support for 2.1 https://gist.github.com/Acxd25/fa30bd44580494dd34c0180f925838e1

"cryogenics-or-assembling" was removed in 2.1.7

I hope I'm not overstepping by posting this here. I just want to help a little.

Not overstepping, though I ended up not needing it. Thank you anyway, though.
