 ## 最近更新
 
-### 版本 0.1.3（最新）
+### 版本 0.1.5（最新）
+
+**新特性：**
+- ✨ **日志系统优化**：将 FastAPI/Uvicorn 日志重定向到 loguru，防止污染 MCP stdio 协议
+- ✨ **工具调试接口**：Web 管理界面新增工具列表和调试功能
+
+**改进：**
+- 🔧 **日志输出控制**：移除控制台日志输出，仅输出到文件，避免干扰 stdio 协议
+- 🔧 **标准库日志拦截**：使用 `InterceptHandler` 拦截所有标准库日志
+- 🔧 **Web API 增强**：新增 `/api/tools` 端点列出可用工具
+
+**技术细节：**
+- 实现了 `InterceptHandler` 类来拦截标准库 logging
+- 配置 uvicorn 使用 `log_config=None` 禁用默认日志
+- 所有日志统一输出到 `~/.acemcp/log/acemcp.log`
+
+### 版本 0.1.4
 
 **新特性：**
 - ✨ **多编码支持**：自动检测和处理多种文件编码（UTF-8、GBK、GB2312、Latin-1）

 ## Recent Updates
 
-### Version 0.1.3 (Latest)
+### Version 0.1.5 (Latest)
+
+**New Features:**
+- ✨ **Logging System Optimization**: Redirect FastAPI/Uvicorn logs to loguru to prevent pollution of MCP stdio protocol
+- ✨ **Tool Debugging Interface**: Web management interface now includes tool listing and debugging functionality
+
+**Improvements:**
+- 🔧 **Log Output Control**: Removed console log output, only output to file to avoid interfering with stdio protocol
+- 🔧 **Standard Library Log Interception**: Use `InterceptHandler` to intercept all standard library logs
+- 🔧 **Web API Enhancement**: New `/api/tools` endpoint to list available tools
+
+**Technical Details:**
+- Implemented `InterceptHandler` class to intercept standard library logging
+- Configured uvicorn with `log_config=None` to disable default logging
+- All logs unified to output to `~/.acemcp/log/acemcp.log`
+
+### Version 0.1.4
 
 **New Features:**
 - ✨ **Multi-Encoding Support**: Automatic detection and handling of multiple file encodings (UTF-8, GBK, GB2312, Latin-1)
