After the above pull request is merged, it is recommended that a tag is created on this repository for the registered package version.

This will be done automatically if the Julia TagBot GitHub Action is installed, or can be done manually through the github interface, or via:

git tag -a v0.2.3 -m "<description of version>" 222486008bb876497f5d2aa1e77aa5dfeda96d91
git push origin v0.2.3

Manually ran git tag because tagbot didn't run, at least not quickly enough.
