Could you update / rebase? I only added unknown -- you added more:

    {warnings, [
        unknown,
        unmatched_returns,
        error_handling,
        underspecs
    ]}

Would love to see this contribution come in 😄

Could you change this:

 %% This group of types are from calendar.erl; we need to use some of them 

To this?

[paulo-ferraz-oliveira]

Sure. Give me a few minutes.

[paulo-ferraz-oliveira]

Done and done.

[paulo-ferraz-oliveira]

Wait, something's off here. I didn't change that many files. Must've something to do with the renaming of branch master.

Edit: yeah, I changed the base branch. Now it's better.

Yay! Looks like you got it fixed :-)

Thanks a bunch!
