[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:

  • Significantly improved startup performance
  • Native system integration without Chromium overhead
  • Enhanced security with Rust backend

✨ New Features

• 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

• Resolved platform detection issues
• Improved error handling in configuration management

📦 Dependencies

• Tauri: 2.8.2
• React: 18.2.0

• 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。
