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

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

Conventional Commit Format

PopKit follows conventional commit format:

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

<body>

<footer>

Commit Types

Type	Description	Version Bump
`feat`	New feature	MINOR (1.0.0 → 1.1.0)
`fix`	Bug fix	PATCH (1.0.0 → 1.0.1)
`perf`	Performance improvement	PATCH
`refactor`	Code refactoring	PATCH
`docs`	Documentation only	PATCH
`test`	Test additions/updates	PATCH
`chore`	Maintenance tasks	PATCH
`ci`	CI/CD changes	PATCH
`build`	Build system changes	PATCH
`style`	Formatting, no code change	PATCH
`BREAKING CHANGE`	Breaking change	MAJOR (1.0.0 → 2.0.0)

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:

Before PR creation (/popkit:git pr)
- Analyzes commits since last release
- Generates changelog entry
- Updates CHANGELOG.md
- Includes changelog in PR description
Before release (/popkit:git release)
- Determines version bump automatically
- Updates CHANGELOG.md with new version
- Generates GitHub release notes
- Creates git tag
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:

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

Best Practices

Use conventional commits - Always format commits as type(scope): description
Include issue references - Add (#123) to link commits to issues
Document breaking changes - Use BREAKING CHANGE footer with migration notes
Scope your commits - Use meaningful scopes like api, ui, core
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:

Consistent changelog format
No missed commits
Proper semantic versioning
Clear breaking change communication
Professional release notes
