I can add the label, sure, but from reading the rules, it does not seem to be required?
There are a bunch of issues that are labeled “minor change”: Issues · duplicati/duplicati · GitHub
All these are things that should be really self-contained.
There are also issues with the label “help wanted”: Issues · duplicati/duplicati · GitHub
These are issues I have not planned working on myself, and they are usually non-core issues (and there are issues with both labels).
Is this sufficient, or do you need them to have the hacktoberfest label?
