Places where we may want to expose the release notes:
- PyPI project description page, but most projects do not list changelogs there unless they happen to keep them in their main README.
- GitHub Releases page, a very good place to see what is new, also allowing you to watch new releases on that project.
- Published documentation
Git changelog does not replace release notes
Looking at git changelog is not the most fulfilling experience as it can contain too much noise, like multiple attempts to reconfigure CI, lots of gradual changes that do not worth mentioning like fixing linting rules.
Most users of a package want to see meaningful changes, sorted by how important they are.
Producing release notes on each change
Many projects spend a considerable amount of time building documentation for how you are supposed to contribute to a project, including writing some release notes.
While I can understand the reasons, this seems like a potential overkill for occasional contributors, especially for new contributors. It creates a barrier and I seen multiple cases where perfect valid contributions never materialized because they missed meeting the changelog requirements.
This is why I am inclined to look for a solution that allows project maintainers to edit release notes without slowing down the flow of incoming changes.
TownCrier is a project gaining popularity and relies on building fragments. Still with only a bit over 200 stars and under a single person control, it will need more time to prove itself.
Reno is the official release note managing platform used by OpenStack. This makes the tool popular among lots of Python developers. As the project is not hosted on GitHub I cannot state how its popularity outside OpenStack. Reno issue tracker does not seem very active either but this may only be a sign of maturity.
Release-Drafter on GitHub
Release Drafter is a GitHub App (or Action) which updates release notes for you. It is not bugfree but so far it proved to be the one that requires a minimal maintenance burden, and avoids clogging your CI with release note changes.
Git hub allows maintainers to edit PR names, descriptions and labels even after PRs are merged. This creates the opportunity to easily rebuild the release notes until you are pleased with the results.
