Thanks to @Sirhexs

Custom Configuration Directory (Cloud Sync)

• Independent Management - Managed via Tauri Store for better isolation and reliability

Thanks to @ZyphrZero

Configuration Directory Switching (WSL Support)

• Auto-Sync on Directory Change - When switching Claude/Codex config directories (e.g., WSL environment), automatically sync current provider to the new directory without manual operation
• Post-Change Sync Utility - Unified postChangeSync.ts utility for graceful error handling without blocking main flow
• Import Config Auto-Sync - Automatically sync after config import to ensure immediate effectiveness
• Smart Conflict Resolution - Distinguishes "fully successful" and "partially successful" states for precise user feedback

Configuration Editor Improvements

• JSON Format Button - One-click JSON formatting in configuration editors
• Real-Time TOML Validation - Live syntax validation for Codex configuration with error highlighting

Load Live Config When Editing

• Protect Manual Modifications - When editing the currently active provider, prioritize displaying the actual effective configuration from live files
• Dual-Source Strategy - Automatically loads from live config for active provider, SSOT for inactive ones

Claude Configuration Data Structure Enhancements

• Granular Model Configuration - Migrated from dual-key to quad-key system for better model tier differentiation
• New fields: ANTHROPIC_DEFAULT_HAIKU_MODEL, ANTHROPIC_DEFAULT_SONNET_MODEL, ANTHROPIC_DEFAULT_OPUS_MODEL, ANTHROPIC_MODEL
• Replaces legacy ANTHROPIC_SMALL_FAST_MODEL with automatic migration
• Backend normalizes old configs on first read/write with smart fallback chain
• UI expanded from 2 to 4 model input fields with intelligent defaults
• ANTHROPIC_API_KEY Support - Providers can now use ANTHROPIC_API_KEY field in addition to ANTHROPIC_AUTH_TOKEN
• Template Variable System - Support for dynamic configuration replacement (e.g., KAT-Coder's ENDPOINT_ID parameter)
• Endpoint Candidates - Predefined endpoint list for speed testing and endpoint management
• Visual Theme Configuration - Custom icons and colors for provider cards

Updated Provider Models

• Kimi k2 - Updated to latest kimi-k2-thinking model

New Provider Presets

Added 5 new provider presets:

• DMXAPI - Multi-model aggregation service
• Azure Codex - Microsoft Azure OpenAI endpoint
• AnyRouter - None-profit routing service
• AiHubMix - Multi-model aggregation service
• MiniMax - Open source AI model provider

Partner Promotion Mechanism

• Support for ecosystem partner promotion (Zhipu GLM Z.ai)
• Sponsored banner integration in README

Improvements

Configuration & Sync

• Unified Error Handling - AppError with internationalized error messages throughout backend
• Fixed apiKeyUrl Priority - Correct priority order for API key URL resolution
• Fixed MCP Sync Issues - Resolved sync-to-other-side functionality failures
• Import Config Sync - Fixed sync issues after configuration import
• Config Error Handling - Force exit on config error to prevent silent fallback and data loss

UI/UX Enhancements

• Unique Provider Icons - Each provider card now has unique icons and color identification
• Unified Border System - Consistent border design across all components
• Drag Interaction - Push effect animation and improved drag handle icons
• Enhanced Visual Feedback - Better current provider visual indication
• Dialog Standardization - Unified dialog sizes and layout consistency
• Form Improvements - Optimized model placeholders, simplified provider hints, category-specific hints
• Usage Display Inline - Usage info moved next to enable button for better space utilization

Complete Internationalization

• Error Messages i18n - All backend error messages support Chinese/English
• Tray Menu i18n - System tray menu fully internationalized
• UI Components i18n - 100% coverage across all user-facing components

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
