## What it is
Changesets is a CLI tool and workflow for managing package versioning and changelog generation, with first-class monorepo support. Contributors declare changes in Markdown files with YAML frontmatter, and the tool handles semver bumps, changelogs, and publishing.

## Use cases
- manage versioning and changelogs in a monorepo
- automate npm package releases from pull requests
- let contributors declare semver bump types per change
- generate changelogs automatically for multiple packages
- keep interdependent workspace packages in sync
- set up a release PR workflow in CI

## When to choose
- you maintain a monorepo with multiple published packages
- you want contributors to describe release intent in PRs
- you need automated version bumps, changelogs, and npm publishing

## When to avoid
- you release a single app with no published packages
- you prefer fully conventional-commit-based release tooling like semantic-release
- you need non-JavaScript package ecosystems
