What is a Changelog?

A changelog is a curated, human-readable list of notable changes for each version. It lives in a file like CHANGELOG.md at the repo root.

Why Changelogs Matter

Users and teammates read changelogs to understand:

  • New features
  • Bug fixes
  • Breaking changes

They make upgrades safer and faster.

Keep a Changelog Format

A common convention groups entries under headings: Added, Changed, Fixed, Removed.

## [1.2.0] - 2024-05-01
### Added
- Search filters
### Fixed
- Login redirect bug

Conventional Commits

Conventional commits use prefixes like feat:, fix:, and BREAKING CHANGE: so tools can build changelogs automatically.

feat: add CSV export
fix: handle empty cart
feat!: drop Node 14 support

Listing Commits Since a Tag

You can preview what changed since the last release using git log with a tag range.

git log v1.1.0..HEAD --oneline

Pretty Log for Notes

Format the log into bullet lines suitable for pasting into release notes.

git log v1.1.0..HEAD --pretty=format:'- %s'

Automated Changelog Tools

Tools like standard-version or conventional-changelog read conventional commits and generate the changelog plus a version bump.

GitHub Auto-Generated Notes

GitHub can auto-generate release notes from merged pull requests when you create a release.

gh release create v1.2.0 --generate-notes

Categorizing with Labels

A .github/release.yml file maps PR labels to changelog sections, so notes group bug fixes and features automatically.

changelog:
  categories:
    - title: Features
      labels: [feature]

Reviewing Before Publishing

Always read generated notes before publishing. Automation drafts them, but a human edits wording and highlights breaking changes.

Linking to Releases

Keep each changelog entry linked to its Git tag and release page so readers can jump to the exact diff.

[1.2.0]: https://github.com/you/repo/compare/v1.1.0...v1.2.0
