@willmcgugan here's the PR

The code changes and documentation look good to me!

I wouldn't personally submit a PR that bumps the version number, but other than that I see no problems. 😊

Thanks @harkabeeparolus! Reason I bumped the version is to hopefully get a new release of the library, so I can install and begin using these changes 🙂

(Also, I don't have permissions to merge the changes since I don't have write access to the repo, so merging is in your hands.)

@harkabeeparolus would a patch version update be more welcome?

- version = "1.8.0"
+ version = "1.8.1"

@harkabeeparolus would a patch version update be more welcome?

I wouldn't know, I'm just a random pythonista on GitHub — I don't have any commit access either. 😊 I just don't think I'd personally make a PR with an included version bump. Unless it was specifically about assisting the maintainers with a new release. But maybe that's just me. 🤔

(I do believe minor version would be appropriate from a Semantic Versioning perspective, since patch versions are supposed to be bugfixes without new features.)
