Writing Guidelines

User-Facing Descriptions

Translate technical commits to user benefits:

• Technical: "Refactor auth state machine"
• User-facing: "Improved reliability of authentication state management"

Breaking Changes

Flag API changes clearly:

### Changed
- **BREAKING**: `login()` now returns `Promise<User>` instead of `Promise<void>`

Output Example

## [1.2.0] - 2024-01-14

### Added
- New health data visualization screen
- Apple HealthKit integration for step counting
- Export health data to PDF

### Changed
- Improved task scheduling performance
- Updated questionnaire UI design

### Fixed
- Fixed race condition in account state initialization
- Resolved infinite loop when no tasks exist

Workflow

1. Run git log to get commits since last release
2. Group commits by category (Added/Changed/Fixed/etc.)
3. Identify breaking changes
4. Write user-facing descriptions
5. Include PR/issue references where available
6. Format following Keep a Changelog structure
