## Breaking Changes

- **New SDK architecture** - Modular design with separate packages for VR/AR/AI
- **API versioning** - All endpoints now versioned (e.g., `/api/v2/...`)
- **Authentication** - OAuth 2.1 required (OAuth 2.0 deprecated)
- **WebRTC** - Upgraded to WebRTC 2.0 specification

## Migration Guide

### From v1.x to v2.0

1. **Update SDK:**
   ```bash
   npm install @wia/virtual-classroom@2.0.0
   ```

2. **Update imports:**
   ```typescript
   // Old
   import { VirtualClassroom } from '@wia/virtual-classroom';

   // New
   import { VirtualClassroom } from '@wia/virtual-classroom/core';
   import { VRClassroom } from '@wia/virtual-classroom/vr';
   import { AITutor } from '@wia/virtual-classroom/ai';
   ```

3. **Update API endpoints:**
   ```typescript
   // Old: /api/v1/sessions
   // New: /api/v2/sessions
   ```

4. **Update authentication:**
   ```typescript
   // Use OAuth 2.1 with PKCE
   ```

## Future Roadmap (v2.1+)

- **Holographic displays** - Support for holographic projections
- **Haptic feedback suits** - Full-body haptic feedback
- **Neural interfaces** - Direct brain-to-computer learning
- **Quantum computing** - Quantum algorithms for AI
- **Interstellar classrooms** - Support for space-based education
