What's our plan with the changelog file? Seems redundant.

I agree. Probably add a big deprecated note at the top but keep it to preserve history.

[Mrod1598]

Could also, have the above just be a comment so then it really doesn't matter. What's meant to be in the parenthese?

[cpheps]

Yeah I'll do that.

Anything you want can go in the parenthesis or just ignore them all together.

I forgot to mention, Dependabot can be told how it should name and label pull requests https://github.com/observIQ/iris/pull/209/files
