@valdeirpsr thanks for your contribution! 🐼

Support for the alphanumerical format would be nice to mention in the documentation (Cnpj.md file). This is not required for us to accept the change, but I believe it's a nice to have.

I'll give some time for other maintainers to review it as well.

Once we're done with reviews and modifications, are you willing to rebase it into a single commit?

Thank you for the contribution, @valdeirpsr! 🐼

We don't use conventional commits, could you squash all your comments into a single one, that just describes what and why these changes we made? It would be awesome! It's okay if you don't do that, but we will squash it ourselves.

Sure! Change made.

@valdeirpsr can you run bin/console lint:docs --fix

It will automatically adjust documentation to conventions and also update the validators.md index.

@henriquemoody can I merge this one?

[henriquemoody]

It's still using conventional commit message, but it's fine. Until we have an actual check I find it unfair to expect that from contributors

[henriquemoody]

So, yes, by all means!

@valdeirpsr I'll wait for a little more. If you can reformat the commit title (just drop the feat:), it will then match the repo guidelines.

Thanks for your patience with us, and again, thanks for the contribution! 🐼
