Thanks for the very nice work!! I'll take this opportunity to check the CI workflow, it was outdated.

@PharmCat Do you think this Documenter error is easy to fix? I want to merge this, but we might not get the latest documentation deployed if the CI fails. Let me know if you want to take a shot at fixing it.

Hi... Mmm... I try to explore. Maybe it will be better to make separate file for Documenter task.

strict keyword removed, some anchor links seems broken or just doctest cant check them correctly. I think would be better to remove this keyword and use array [:autodocs_block, :cross_references, :docs_block, :doctest, :eval_block, :example_block, :footnote, :linkcheck, :meta_block, :missing_docs, :parse_error, :setup_block] without :linkcheck

I missed that, I think your suggestion is good
