This should have a newsfragement.

+1 to what @tomprince said. However I'm not sure what should we prefix the files with in the absence of bug numbers.

💛 - Coveralls

[MihaiTabara]

Come to think about it after chatting with @nthomas-mozilla - this raises the question, some of the PRs are not quliafiying for a bug number, hence am not sure they should really have a newsfragment. I mean, any code change that can affect functionality should have a bug number I suppose, but for doc fixing or tooling (e.g. tox, coveralls, etc) I don't think it's worth filing a bug.

@tomprince what do you think?

[MihaiTabara]

Let's make a consensus: any changes that don't have a tracking bug number in Bugzilla can ignore the newsfragment I suppose. In this category we can definitely shove the update of the info files (README, requirements, etc). We can always come back and change this.

Pushing this to be grabbed in the upcoming 7.5.0 roll-out
