This is failing due to issue #695 not because of any changes made here.

Why <0.18?

[itdependsnetworks]

I did not want to be over permissive

[itdependsnetworks]

Let me elaborate, I did not want to be so permissive not knowing your initial intention

[ktbyers]

@itdependsnetworks Can you rebase and update your poetry.lock file (to get David's mypy fix).

Also we should just do:

"ruamel.yaml" = "0.16.*"

That should allow 0.16 and greater, but disallow 1.x.x.

Alternatively we could just do >=0.16

[itdependsnetworks]

I went with Alternatively we could just do >=0.16, since semantic versioning technically treats every "minor" version as potentially non-backwards compatible, and poetry respects that.

Thanks!
