## Changes

### New Onboarding Experience

Claude Code now features a comprehensive onboarding flow for first-time users:

- **Interactive setup screens** guide you through initial configuration
- **Theme selection** to personalize your experience from the start
- **Security awareness** with explicit information about Claude's capabilities
- **Terminal optimization** with specific key binding recommendations for your terminal

When you first run Claude Code v1.0.70, you'll be greeted with setup screens that help configure:

- Visual theme preferences
- OAuth login or API key authentication
- Terminal-specific settings (e.g., Option+Enter for new lines in Apple Terminal)

### Enhanced Security Model

- **Explicit permission dialogs** for MCP servers and hooks
- **Trust management** for code execution permissions
- **API key validation** with user confirmation for custom ANTHROPIC_API_KEY usage
- Clear security notes displayed during onboarding about Claude's file system access

### Major Codebase Refactoring

- **66.3% structural similarity** to v1.0.69 (significant reorganization)
- **2,889 functions removed** and 2,257 new functions added
- **Complete removal of Sentry telemetry** and error tracking for improved privacy
- Reduced external dependencies and cleaner module structure

### Removed Telemetry

All Sentry integration has been removed, including:

- Error tracking and reporting
- Performance monitoring
- User activity telemetry
- Database instrumentation (Express, PostgreSQL, MySQL)
- Browser and network instrumentation

This means Claude Code no longer sends crash reports or usage data to external services, enhancing user privacy.

### Module System Updates

- Added support for `createRequire` from Node.js native module system
- Better CommonJS and ES module interoperability
- Improved module loading and dependency resolution

### Process Handling

- Reorganized Windows-specific ENOENT error handling
- Maintained full cross-platform process spawning support
- Better error messages for missing executables

### File System Operations

Enhanced file system capabilities with new imports for:

- File watching (`watchFile`, `unwatchFile`)
- Stream operations (`createReadStream`, `createWriteStream`)
- Path handling for both POSIX and Windows systems

### Terminal Integration

- Automatic detection and optimization for different terminal emulators
- Custom key binding recommendations based on your terminal
- Improved handling of iTerm2 settings restoration

### Authentication Flow

- Clearer distinction between Claude AI subscription and Console API billing
- Better handling of custom API keys with validation
- Streamlined OAuth login process

### Export Structure

The main module now exports three functions:

- `showSetupScreens` - Displays the onboarding flow
- `setup` - Main initialization function
- `completeOnboarding` - Marks onboarding as complete

### Code Organization

- Significant module restructuring for better maintainability
- Removed monitoring and instrumentation code
- Simplified export structure
- Cleaner dependency graph

### Performance

- Reduced bundle size due to removed dependencies
- Faster startup time without telemetry initialization
- More efficient module loading

## Bug Fixes

- Improved Windows process spawning error handling
- Better Node.js version compatibility checks
- Fixed issues with terminal settings restoration after interruption

## Notes

This version represents a major cleanup and privacy-focused release. The removal of all telemetry and external monitoring makes Claude Code more privacy-respecting while maintaining all core functionality. The new onboarding experience ensures users have a smooth first-run experience with proper configuration and security awareness.
