This builds upon gh-12678, it bumps the version of one of the requirements. Hopefully it also regenerates CI logs which are no longer available in the referenced pull request.

Hi! This is the friendly automated conda-forge-linting service.

I wanted to let you know that I linted all conda-recipes in your PR (recipes/chemicals, recipes/dot2tex, recipes/pyneqsys, recipes/pyodesys, recipes/sym) and found some lint.

Here's what I've got...

For recipes/chemicals:

• Feedstock with the same name exists in conda-forge.

For recipes/chemicals:

• noarch: python recipes are recommended to have a lower bound on the python version. This recommendation will become a requirement in the future.

For recipes/dot2tex:

• noarch: python recipes are recommended to have a lower bound on the python version. This recommendation will become a requirement in the future.

For recipes/pyneqsys:

• noarch: python recipes are recommended to have a lower bound on the python version. This recommendation will become a requirement in the future.

For recipes/sym:

• noarch: python recipes are recommended to have a lower bound on the python version. This recommendation will become a requirement in the future.

Thanks for the mention. Any tasks still pending for the inclusion of version 0.8.1?

[bjodah]

I don't think so, I just wanted to see if you could think of anything. If not I think this is ready. So I guess we'll simply wait for someone to find the time to review. Thank you for getting started with this and being willing to help maintain the recipes!.

Chempy is very important to my work, it’s a pleasure to do that. I'm sorry I didn't dedicate myself more recently, but the work has taken me a long time too.
