## What it is
A family of Node.js tools that generate CHANGELOG.md files and release notes from git commit history following conventions like Conventional Commits. It includes a CLI, a chainable JS API, and composable parser/filter/writer packages, plus a recommended version bump tool.

## Use cases
- generate changelog from git commit messages
- automate release notes from conventional commits
- determine next semver version bump from commits
- write CHANGELOG.md for npm package releases
- generate changelogs for monorepo packages
- integrate changelog generation into CI/CD release pipeline

## When to choose
- your project follows Conventional Commits or Angular commit conventions
- you want automated, grouped, linked changelogs without hand-editing
- you need a JS API to build custom release tooling
- you want commit history to drive major/minor/patch version decisions

## When to avoid
- your commit history is unstructured and you can't adopt a commit convention
- you need a full release automation tool rather than changelog generation (consider semantic-release or commit-and-tag-version built on top)
- your project doesn't use git
