Release

Stop and inform the user if any check fails.

2. Determine new version

Read the current version from package.json.

• patch: bump patch (e.g. 1.44.0 → 1.44.1)
• minor: bump minor (e.g. 1.44.0 → 1.45.0)
• explicit version: use as-is

3. Collect changes since last release

git log --oneline $(git describe --tags --abbrev=0)..HEAD

Categorize commits:

Skip entirely:

• The release commit itself (e.g. v1.44.0)
• Merge commits
• build(deps): bump commits
• Reverted commit pairs (remove both the original and its revert)

4. Collect contributors

Get the GitHub username for each commit. Only the first author — ignore co-authors.

• Commits with a PR number (e.g. feat(retry): add shouldRetry (#1585)):

  gh pr view {PR_NUMBER} --repo toss/es-toolkit --json author --jq '.author.login'
  

• Commits without a PR number:

  gh api repos/toss/es-toolkit/commits/{FULL_SHA} --jq '.author.login'
  

Deduplicate, sort alphabetically, format as @{username}.

5. Generate changelog entry

Follow the existing CHANGELOG.md style exactly:

## Version v{NEW_VERSION}

Released on {Month Dayth, Year}.

- {Description}. ([#{PR_NUMBER}])
- {Description}.

We sincerely thank {contributors} for their contributions. We appreciate your great efforts!

Rules:

• Features first, then fixes, then other changes
• English, past tense ("Added", "Fixed", "Enhanced")
• Include ([#{PR_NUMBER}]) only when a PR number exists
• Use today's date for "Released on"
• Separate contributors with , and use and before the last one

6. Preview and confirm

Show the user:

• Version change: v{OLD} → v{NEW}
• Full changelog entry
• Files to modify: package.json, jsr.json, CHANGELOG.md

Use AskUserQuestion to get approval before proceeding.

7. Apply changes

1. package.json: "version": "{OLD}" → "version": "{NEW}"
2. jsr.json: "version": "{OLD}" → "version": "{NEW}"
3. CHANGELOG.md: Insert new entry after # es-toolkit Changelog\n

8. Commit and tag

git add package.json jsr.json CHANGELOG.md
git commit -m "v{NEW_VERSION}"
git tag "v{NEW_VERSION}"

Commit message is the version string only (e.g. v1.45.0). No body. No co-author footer.

9. Push confirmation

Use AskUserQuestion to ask "Push to remote?".

If approved:

git push origin main
git push origin "v{NEW_VERSION}"

NEVER push without explicit confirmation.

10. Report

## Release v{NEW_VERSION}

- Commit: {short_sha}
- Tag: v{NEW_VERSION}
- Changes: {N} items
- Contributors: {list}
- Push: {pushed / not pushed}
