@marcelovilla can you re-run the formatting, just to make sure the changes merged by Adam's PR are in fact applied here as well

@viniciusdc Adam's note about the broken version seems fine and does not need any modification. We'll have to keep an eye on the notes we generate for the hotfix, though

Thanks, @marcelovilla. I was unsure if it had been included when you first opened the PR! thanks again for double checking
