# Changeset & Release Manager

## Overview

Automate the creation of changesets following project conventions, ensuring proper version bumps and well-documented release notes.

## When to Use

- After completing a feature or fix
- Before creating a PR
- When preparing a release
- To document breaking changes

## What is a Changeset?

A changeset is a markdown file in the `.changeset/` directory that describes:
1. Which packages are affected
2. What type of version bump (patch/minor/major)
3. A description of the change

## Changeset Types

| Type | When to Use | Version Change |
|------|-------------|----------------|
| `patch` | Bug fixes, documentation, refactoring, dependency updates | 1.0.0 → 1.0.1 |
| `minor` | New features, non-breaking enhancements | 1.0.0 → 1.1.0 |
| `major` | Breaking changes, API modifications | 1.0.0 → 2.0.0 |

## Decision Guide

### Use `patch` for:
- Bug fixes that don't change behavior
- Documentation updates
- Internal refactoring (no API changes)
- Dependency updates (non-breaking)
- Performance improvements
- Code style/linting fixes

### Use `minor` for:
- New features
- New CLI commands
- New configuration options
- Enhanced functionality
- New entity types support
- Non-breaking API additions

### Use `major` for:
- Breaking configuration changes
- Removed features or commands
- Changed CLI interface
- Required migration steps
- Node.js version requirement changes

## Creating a Changeset

### Interactive Method

```bash
pnpm changeset
```

Follow the prompts:
1. Select affected packages (space to select)
2. Choose bump type for each package
3. Write a summary of changes

### Manual Method

Create a file in `.changeset/` with a random name:

```markdown
---
"@saleor/configurator": minor
---

Add support for reference attributes with entityType field

- Attributes of type REFERENCE now require an entityType field
- Introspection properly captures entity type references
- Deploy correctly handles reference attribute creation
```

### File Format

```markdown
---
"package-name": patch|minor|major
---

Short description of the change (shown in CHANGELOG)

Optional longer description with:
- Bullet points for details
- Code examples if needed
- Migration instructions for breaking changes
```

## Release Workflow

### 1. Create Changeset

```bash
pnpm changeset
git add .changeset/
git commit -m "chore: add changeset for feature"
```

### 2. PR and Review

- Changeset is part of the PR
- Reviewers can suggest bump type changes

### 3. Merge to Main

- Changesets action creates "Version Packages" PR
- This PR updates version and CHANGELOG

### 4. Merge Version PR

- Triggers npm publish
- Creates GitHub release

## Checking Status

```bash
# See what changesets exist
npx changeset status

# Preview version bump
npx changeset version --dry-run
```

## Common Mistakes

| Mistake | Issue | Fix |
|---------|-------|-----|
| Wrong bump type | Unexpected version | Review decision guide above |
| Vague description | Poor CHANGELOG | Be specific about changes |
| Missing changeset | No release notes | Always add before PR |
| Multiple changesets | Fragmented notes | Combine related changes |
| Not including context | Hard to understand | Explain *why* not just *what* |

## Common Scenarios

For detailed examples of common scenarios including:
- Bug fixes, new features, breaking changes
- Multiple related changes
- Consolidated changesets
- Pre-release versions
- Best practices for descriptions
