I was trying to standardize release notes across teams. The idea was to use ready-to-use templates that parse commits and produce SemVer-aware notes: grouped by change type, list of breaking changes, and auto-tagged version. I started with a template that looks for conventional commit prefixes, but our repo has inconsistent messages.
So I extended the template to accept a small mapping file that maps common team prefixes to conventional types. The template then runs commit parsing, groups changes, and attaches a generated changelog to the release draft. That cut manual write-up time a lot.
Has anyone built templates that handle messy commit history? How do you reconcile freeform commits with automated semver release note generation?
we made a template that normalizes commits using a small rules file, then generates release notes with sections for breaking changes. you can edit the template visually and test on a branch. it sped up release authorship for our group.
I layered templates: first normalize commits with regex rules and a fallback classifier (a small LLM). Then feed the normalized list into the template that creates sections and a suggested semver bump. That way you don’t need perfect commit hygiene to get decent notes.
If you have legacy commits, consider a retroactive reclassification step that runs once and tags past commits in a metadata file. New releases then use that metadata as a baseline and only parse recent commits live.
Templates that work reliably need two things: a robust commit classification layer and a fallback human review. Use a classifier tuned on your own history rather than generic rules. For the template itself, include an explicit breaking changes section and a rationale line for the bump. If the classifier confidence is low, insert a highlighted note in the draft release to force a quick human check. Over time, feed human corrections back into the classifier.
