+### Fixed - 🐛 WebSocket 关键修复
+
+#### 修复 WebSocket frame payload 解析问题
+- **✅ 单包消息 payload 恢复** - 修复相比版本 52e069ee 的关键回归问题
+  - 单包消息的 payload 在 `process_frame_packages_internal` 中被 `take()` 但未重新设置
+  - 导致下游处理器接收到没有 payload 的 frame，事件处理失败
+  - 现在正确恢复单包消息的 payload，确保消息完整传递
+- **🧪 完整测试覆盖** - 添加 WebSocket payload 处理的单元测试
+  - `test_single_package_payload_preservation` - 验证单包消息 payload 保存
+  - `test_multi_package_payload_combination` - 验证多包消息组合逻辑
+  - 测试辅助方法 `new_for_test()` 支持隔离测试
+
+#### WebSocket 客户端示例增强
+- **📡 完整 WebSocket 连接示例** - `websocket_client.rs` 添加实际功能
+  - 集成 `LarkWsClient::open()` 建立 WebSocket 连接
+  - 配置 `EventDispatcherHandler` 处理实时事件
+  - 注册 `p2_im_message_receive_v1` 事件处理器
+  - 提供完整的错误处理和日志输出
+- **📚 改进示例文档** - 清晰的功能说明和使用指导
+  - WebSocket 功能特性说明
+  - 事件类型和处理器注册示例
+  - 特性标志 (`--features websocket`) 使用说明
+
+### Technical Details
+- 修复了 WebSocket 消息处理的核心逻辑缺陷
+- 所有测试通过，代码检查无警告
+- 向后兼容，不影响现有 API
