My code follows the code style of this project.

I'm pretty very new to rust and I'm not entirely sure what I've done around date parsing is correct.

Feedback very welcome

I'll look at test coverage as well.

Thanks for the PR! I will be reviewing this soon. No need to worry about test coverage or the code style for now.

Can you also update CHANGELOG.md file at the root of the repository by running git-cliff --latest with these changes? I want to see if the previously deleted first-time contributors will come back :)

[mcwarman]

Updated the CHANGELOG.md, I had to run cargo run -- -o CHANGELOG.md and remove [unreleased] section manually.

--latest only returned latest tag.
