Pop Changelog Automation

Enhanced Changelog Automation

Overview

Automatically generate CHANGELOG.md updates and GitHub release notes from conventional commits with semantic versioning analysis. This skill provides intelligent version management and changelog generation that surpasses Auto Claude's capabilities.

Key Features

1. Semantic Versioning - Auto-detect MAJOR.MINOR.PATCH bumps
2. Auto-Categorization - Group commits by type (feat, fix, breaking, etc.)
3. Breaking Change Detection - Highlight breaking changes with migration notes
4. Release Notes Generation - Auto-generate GitHub release notes
5. Integration Ready - Seamless integration with git workflow

Conventional Commit Format

PopKit follows conventional commit format:

<type>(<scope>): <subject>

<body>

<footer>

Commit Types

Version Bump Rules

The changelog generator automatically determines the appropriate version bump:

# MAJOR bump (1.0.0 → 2.0.0)
- Any commit with "BREAKING CHANGE" in body or footer
- Incompatible API changes
- Major architectural changes

# MINOR bump (1.0.0 → 1.1.0)
- feat: commits
- New features added
- Backward-compatible functionality

# PATCH bump (1.0.0 → 1.0.1)
- fix: commits
- Bug fixes
- Performance improvements
- Refactoring
- Documentation updates

Usage

Automatic (Recommended)

Changelog is automatically updated when:

1. Before PR creation (/popkit:git pr)

   • Analyzes commits since last release
   • Generates changelog entry
   • Updates CHANGELOG.md
   • Includes changelog in PR description

2. Before release (/popkit:git release)

   • Determines version bump automatically
   • Updates CHANGELOG.md with new version
   • Generates GitHub release notes
   • Creates git tag

3. On PR merge (via hook)

   • Updates changelog for merged changes
   • Prepares for next release

Integration with Git Workflow

PR Creation Flow

# When creating PR with /popkit:git pr:

1. Detect commits since last release
2. Analyze commit types
3. Determine version bump (if release PR)
4. Generate changelog entry
5. Update CHANGELOG.md
6. Include changelog in PR description
7. Create PR

Release Flow

# When creating release with /popkit:git release:

1. Get commits since last version tag
2. Determine semantic version bump
3. Calculate next version
4. Generate changelog entry
5. Update CHANGELOG.md
6. Generate GitHub release notes
7. Save release notes file
8. Create git tag with version
9. Create GitHub release with notes
10. Publish release

Breaking Change Format

When introducing breaking changes, use this format:

feat(api): Change authentication endpoint

Move authentication from /auth to /api/auth for consistency with REST API structure.

BREAKING CHANGE: Authentication endpoint changed from /auth to /api/auth
Migration: Update all API calls to use new endpoint
See migration guide: docs/migrations/v1.1.0.md

The changelog generator will:

• Detect "BREAKING CHANGE" in footer
• Categorize as MAJOR version bump
• Extract migration notes from footer
• Highlight in both CHANGELOG.md and release notes

Validation

The changelog generator validates:

1. Conventional commit format - Ensures commits follow type(scope): description format
2. Version bump logic - Correctly determines MAJOR/MINOR/PATCH
3. Breaking change detection - Identifies "BREAKING CHANGE" in footer
4. Issue reference extraction - Finds all #N references
5. Categorization - Groups commits by type with proper priority

Best Practices

1. Use conventional commits - Always format commits as type(scope): description
2. Include issue references - Add (#123) to link commits to issues
3. Document breaking changes - Use BREAKING CHANGE footer with migration notes
4. Scope your commits - Use meaningful scopes like api, ui, core
5. Write clear descriptions - Make it easy to understand the change

Value Delivery

Time Saved:

• Manual changelog: 30-45 minutes per release
• Automated changelog: 30 seconds
• Savings: 98%+ time reduction

Quality Improved:
