## Changes

# Claude Code v0.2.98 Changelog

### Dynamic Model Configuration

The CLI now provides enhanced model selection capabilities with runtime configuration support:

- **Statsig Integration**: Model configuration now integrates with Statsig for A/B testing and feature flags
- **Environment Variable Priority**: The `ANTHROPIC_MODEL` environment variable takes precedence over other configuration methods
- **Fallback Chain**: Implements a robust fallback mechanism for model selection:

- Check environment configuration
- Check process environment variable
- Use Statsig-provided model
- Fall back to default model

**Example usage**

`# Set a specific model via environment variable
ANTHROPIC_MODEL=claude-3-opus-20240229 claude

# The model will persist across sessions if set in config`

### Settings UI Enhancements

The settings panel now tracks configuration changes more comprehensively:

- **Change Tracking**: All setting modifications are now logged with telemetry events
- **Model Configuration**: Removed the separate model configuration UI in favor of environment-based settings
- **Verbose Output**: The verbose setting is now properly persisted and tracked

### MCP Configuration File

New support for `.mcp.json` configuration files in your project directory:

`function saveMcpConfig(config) { let mcpPath = path.join(cwd(), ".mcp.json"); writeFileSync(mcpPath, JSON.stringify(config, null, 2), { encoding: "utf8" }); }` This allows you to configure MCP servers and tools on a per-project basis.

### Parent Process Detection

New utilities for detecting if Claude Code is running as a child of a specific process:

`function isChildOfProcess(pid) {
  if (!isProcessAlive(pid)) return false;
  // Walks up the process tree to check ancestry
  // Useful for IDE integration detection
}`

### IDE Name Resolution

Enhanced IDE detection with friendly name mapping:

`function getIDEDisplayName(ideId) { switch (ideId) { case "vscode": return "VS Code"; case "cursor": return "Cursor"; case "windsurf": return "Windsurf"; case "pycharm": return "PyCharm"; case "intellij": return "IntelliJ IDEA"; case "webstorm": return "WebStorm"; // ... and many more IDEs } }` Supports detection of 20+ different IDEs including JetBrains suite, VS Code variants, and Android Studio.

### Enhanced Limit Status Tracking

The rate limit status now includes time-based information:

`// Previous version { status: "limited" } // New version { status: "limited", hoursTillReset: 3 // Hours until rate limit resets }` This provides users with better visibility into when they can resume using the service.

### Conversation Path Resolution

New functionality to resolve and track conversation paths across sessions:

`async function resolveConversationPaths() { // Automatically resolves parent-child relationships // between conversations for better context tracking }` This helps maintain conversation context when switching between related discussions.

## Technical Improvements

- **Stream Handling**: Added `PassThrough` stream support for better data pipeline management
- **Removed Dependencies**: Cleaned up unused imports and variables for a leaner codebase
- **State Management**: Introduced new Recoil atoms for slow/capable model configuration with proper state persistence

## Bug Fixes

- Fixed model configuration not persisting across restarts
- Improved error handling in process detection utilities
- Enhanced telemetry event tracking for configuration changes
