## [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

- **Enhanced security model** with explicit permission declarations
- **Better platform detection** using Tauri's native APIs

### 🔧 Technical Improvements

- 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

## [2.0.0] - Previous Electron Release

### Features

- Multi-provider configuration management
- Quick provider switching
- Import/export configurations
- Preset provider templates

---

## [1.0.0] - Initial Release

### Features

- Basic provider management
- Claude Code integration
- Configuration file handling
## [Unreleased]

### ⚠️ Breaking Changes

- Tauri 命令统一仅接受 `app` 参数，移除历史 `app_type`/`appType` 兼容路径；传入未知 `app` 时会明确报错，并提示可选值。

### 🔧 Improvements

- 统一 `AppType` 解析：集中到 `FromStr` 实现，命令层不再各自实现 `parse_app()`，减少重复与漂移。
- 错误消息本地化与更友好：对不支持的 `app` 返回中英双语提示，并包含可选值清单。

### 🧪 Tests

- 新增单元测试覆盖 `AppType::from_str`：大小写、裁剪空白、未知值错误消息。
