FAQ
What does this tool tell you?
The Release Notes Format Checker validates Keep a Changelog 1.0 format — version headers, ISO 8601 dates, section names, yanked release syntax, and comparison links.
What affects the result most?
Keep a Changelog format: ## [version] - YYYY-MM-DD header, Added/Changed/Deprecated/Removed/Fixed/Security sections. GitHub Release format: markdown, auto-generated from conventional commits via gh CLI or Actions. Version header: ## [1.2.3] - 2024-01-15 — ISO 8601 date required, brackets around version.
How should I use the result?
Treat the tool's output as a first-pass check, not a proof of correctness. A clean pass means no issues in the patterns this tool recognizes; a failure points to a specific problem you can investigate in your source. The underlying spec is the authoritative source for edge cases.
