Thanks for that. A project I contribute to recently had a discussion and policy change about what the right threshold is for adding someone to the official list of contributors (which also means a mention in the release notes and blog post accompanying a new release). On advice from a Sage (sagemath.org) developer: anything. The core devs gain little by withholding the "contributor" merit badge, and simple recognition is usually the main thing that motivates a newcomer to follow through with a patch and stay with the community. So now, if a new developer helps us with any contribution -- one-line patch, test case, documentation -- we offer to add their name to the contributors list and news file.
