## 📦 What's New in v3.6.1 (2025-11-10)

This release focuses on **user experience optimization** and **configuration parsing robustness**, fixing several critical bugs and enhancing the usage query system.

### ✨ New Features

#### Usage Query System Enhancements

- **Credential Decoupling** - Usage queries can now use independent API Key and Base URL, no longer dependent on provider configuration
  - Support for different query endpoints and authentication methods
  - Automatically displays credential input fields based on template type
  - General template: API Key + Base URL
  - NewAPI template: Base URL + Access Token + User ID
  - Custom template: Fully customizable
- **UI Component Upgrade** - Replaced native checkbox with shadcn/ui Switch component for modern experience
- **Form Unification** - Unified use of shadcn/ui Input components, consistent styling with the application
- **Password Visibility Toggle** - Added show/hide password functionality (API Key, Access Token)

#### Form Validation Infrastructure

- **Common Schema Library** - New JSON/TOML generic validators to reduce code duplication
  - `jsonConfigSchema`: Generic JSON object validator
  - `tomlConfigSchema`: Generic TOML format validator
  - `mcpJsonConfigSchema`: MCP-specific JSON validator
- **MCP Conditional Field Validation** - Strict type checking
  - stdio type requires `command` field
  - http type requires `url` field

#### Partner Integration

- **PackyCode** - New official partner
  - Added to Claude and Codex provider presets
  - 10% discount promotion support
  - New logo and partner identification

---

### 🔧 Improvements

#### User Experience

- **Drag Sort Sync** - Tray menu order now syncs with drag-and-drop sorting in real-time
- **Enhanced Error Notifications** - Provider switch failures now display copyable error messages
- **Removed Misleading Placeholders** - Deleted example text from model input fields to avoid user confusion
- **Auto-fill Base URL** - All non-official provider categories automatically populate the Base URL input field

#### Configuration Parsing

- **CJK Quote Normalization** - Automatically handles IME-input fullwidth quotes to prevent TOML parsing errors
  - Supports automatic conversion of Chinese quotes (" " ' ') to ASCII quotes
  - Applied in TOML input handlers
  - Disabled browser auto-correction in Textarea component
- **Preserve Custom Fields** - Editing Codex MCP TOML configuration now preserves unknown fields
  - Supports extension fields like timeout_ms, retry_count
  - Forward compatibility with future MCP protocol extensions

---

### 🐛 Bug Fixes

#### Critical Fixes

- **Fixed usage script panel white screen crash** - FormLabel component missing FormField context caused entire app to crash
  - Replaced with standalone Label component
  - Root cause: FormLabel internally calls useFormField() hook which requires FormFieldContext
- **Fixed CJK input quote parsing failure** - IME-input fullwidth quotes caused TOML parsing errors
  - Added textNormalization utility function
  - Automatically normalizes quotes before parsing
- **Fixed drag sort tray desync** (#179) - Tray menu order not updated after drag-and-drop sorting
  - Automatically calls updateTrayMenu after sorting completes
  - Ensures UI and tray menu stay consistent
- **Fixed MCP custom field loss** - Custom fields silently dropped when editing Codex MCP configuration
  - Uses spread operator to retain all fields
  - Preserves unknown fields in normalizeServerConfig

#### Stability Improvements

- **Error Isolation** - Tray menu update failures no longer affect main operations
  - Decoupled tray update errors from main operations
  - Provides warning when main operation succeeds but tray update fails
- **Safe Pattern Matching** - Replaced `unwrap()` with safe pattern matching
  - Avoids panic-induced app crashes
  - Tray menu event handling uses match patterns
- **Import Config Classification** - Importing from default config now automatically sets category to `custom`
  - Avoids imported configs being mistaken for official presets
  - Provides clearer configuration source identification

## Architecture Refactoring

### Backend (Rust) - 5 Phase Refactoring

1. **Phase 1**: Unified error handling (`AppError` + i18n error messages)
2. **Phase 2**: Command layer split by domain (`commands/{provider,mcp,config,settings,plugin,misc}.rs`)
3. **Phase 3**: Integration tests and transaction mechanism (config snapshot + failure rollback)
4. **Phase 4**: Extracted Service layer (`services/{provider,mcp,config,speedtest}.rs`)
5. **Phase 5**: Concurrency optimization (`RwLock` instead of `Mutex`, scoped guard to avoid deadlock)

### Frontend (React + TypeScript) - 4 Stage Refactoring

1. **Stage 1**: Test infrastructure (vitest + MSW + @testing-library/react)
2. **Stage 2**: Extracted custom hooks (`useProviderActions`, `useMcpActions`, `useSettings`, `useImportExport`, etc.)
3. **Stage 3**: Component splitting and business logic extraction
4. **Stage 4**: Code cleanup and formatting unification

### Testing System

- **Hooks Unit Tests** - 100% coverage for all custom hooks
- **Integration Tests** - Coverage for key processes (App, SettingsDialog, MCP Panel)
- **MSW Mocking** - Backend API mocking to ensure test independence
- **Test Infrastructure** - vitest + MSW + @testing-library/react

### Code Quality

- **Unified Parameter Format** - All Tauri commands migrated to camelCase (Tauri 2 specification)
- **Semantic Clarity** - `AppType` renamed to `AppId` for better semantics
- **Centralized Parsing** - Unified `app` parameter parsing with `FromStr` trait
- **DRY Violations Cleanup** - Eliminated code duplication throughout codebase
- **Dead Code Removal** - Removed unused `missing_param` helper, deprecated `tauri-api.ts`, redundant `KimiModelSelector`

---

## Internal Optimizations (User Transparent)

### Removed Legacy Migration Logic

v3.6.0 removed v1 config auto-migration and copy file scanning logic:

- **Impact**: Improved startup performance, cleaner codebase
- **Compatibility**: v2 format configs fully compatible, no action required
- **Note**: Users upgrading from v3.1.0 or earlier should first upgrade to v3.2.x or v3.5.x for one-time migration, then upgrade to v3.6.0

### Command Parameter Standardization

Backend unified to use `app` parameter (values: `claude` or `codex`):

- **Impact**: More standardized code, friendlier error prompts
- **Compatibility**: Frontend fully adapted, users don't need to care about this change

---

## Dependencies

- Updated to **Tauri 2.8.x**
- Updated to **TailwindCSS 4.x**
- Updated to **TanStack Query v5.90.x**
- Maintained **React 18.2.x** and **TypeScript 5.3.x**
