changelog

Automating changelog generation from git history involves mapping Conventional Commits to human-readable release notes under the Keep a Changelog format. This creates structured CHANGELOG.md files with categorized version sections and footer comparison links automatically.

Keep a Changelog is a standardized format for release notes that separates entries into Unreleased and versioned sections with dates and comparison links. It provides strict formatting rules to ensure project histories remain readable and auditable.

To update an existing CHANGELOG.md, new git commit entries are appended under the Unreleased section or promoted into a new versioned release. The process detects whether changes belong in Unreleased or a new release and formats them accordingly.

Conventional Commits mappings allow automatic categorization of changelog entries by translating commit message types into structured release note categories. This converts raw git history into human-friendly entries suitable for public release notes.

Changelog automation supports multiple versioned releases by detecting Unreleased versus released versions and generating versioned sections with dates and footer comparison links. It handles structured release notes across all project versions per the Keep a Changelog specification.

Automating release notes from git history requires commits to follow Conventional Commits standards for proper categorization. Non-standard commit messages may not map correctly to Keep a Changelog categories, limiting the accuracy of automated changelog generation.
