+  }
+  ```
+
+### Changed
+
+- 下载器参数timeout移除。
+
+  可以使用文件系统的看门狗机制代替。
+
+- (#632) IFilterRule接口变动。
+
+  收集器可以指定搜寻的资源类型，在收集目录资产量巨大的情况下，可以极大加快打包速度！
+
+  ```csharp
+  public interface IFilterRule
+  {
+      /// <summary>
+      /// 搜寻的资源类型
+      /// 说明：使用引擎方法搜索获取所有资源列表

+  }
+  ```
+
+

+
+- 新增了资源系统初始化参数：UseWeakReferenceHandle 
+
+  目前处于预览版，可以在引擎设置页面开启宏：YOOASSET_EXPERIMENTAL
+
+  ```csharp

+  /// 启用弱引用资源句柄
+  /// </summary>
+  public bool UseWeakReferenceHandle = false;
+  ```
+
+- 内置文件系统和缓存文件系统新增初始化参数：FILE_VERIFY_MAX_CONCURRENCY

+  }
+  ```
+
+  
+
+## [2.3.14] - 2025-07-23
+
+**重要**：**所有下载相关的超时参数（timeout）已更新判定逻辑**

+
+  ```csharp
+  public interface IManifestProcessServices
+  {
+      /// <summary>
+      /// 处理资源清单（压缩或加密）
+      /// </summary>
+      byte[] ProcessManifest(byte[] fileData);
+  }
+  
+  public interface IManifestRestoreServices
+  {
+      /// <summary>
+      /// 还原资源清单（解压或解密）
+      /// </summary>
+      byte[] RestoreManifest(byte[] fileData);
+  }
+  ```
+
+## [2.3.12] - 2025-07-01

+      /// 处理资源清单（压缩和加密）
+      /// </summary>
+      byte[] ProcessManifest(byte[] fileData);
+          
+      /// <summary>
