## [3.0.0] - 2025-08-27

### 🚀 Major Changes
- **Complete migration from Electron to Tauri 2.0** - The application has been completely rewritten using Tauri, resulting in:
  - **90% reduction in bundle size** (from ~150MB to ~15MB)
  - **Significantly improved startup performance**
  - **Native system integration** without Chromium overhead
  - **Enhanced security** with Rust backend

### ✨ New Features
- **Native window controls** with transparent title bar on macOS
- **Improved file system operations** using Rust for better performance
- **Enhanced security model** with explicit permission declarations
- **Better platform detection** using Tauri's native APIs

### 🔧 Technical Improvements
- Migrated from Electron IPC to Tauri command system
- Replaced Node.js file operations with Rust implementations
- Implemented proper CSP (Content Security Policy) for enhanced security
- Added TypeScript strict mode for better type safety
- Integrated Rust cargo fmt and clippy for code quality

### 🐛 Bug Fixes
- Fixed bundle identifier conflict on macOS (changed from .app to .desktop)
- Resolved platform detection issues
- Improved error handling in configuration management

### 📦 Dependencies
- **Tauri**: 2.8.2
- **React**: 18.2.0
- **TypeScript**: 5.3.0
- **Vite**: 5.0.0

### 🔄 Migration Notes
For users upgrading from v2.x (Electron version):
- Configuration files remain compatible - no action required
- The app will automatically migrate your existing provider configurations
- Window position and size preferences have been reset to defaults

#### Backup on v1→v2 Migration (cc-switch internal config)
- When the app detects an old v1 config structure at `~/.cc-switch/config.json`, it now creates a timestamped backup before writing the new v2 structure.
- Backup location: `~/.cc-switch/config.v1.backup.<timestamp>.json`
- This only concerns cc-switch's own metadata file; your actual provider files under `~/.claude/` and `~/.codex/` are untouched.

### 🛠️ Development
- Added `pnpm typecheck` command for TypeScript validation
- Added `pnpm format` and `pnpm format:check` for code formatting
- Rust code now uses cargo fmt for consistent formatting
