 All notable changes to this package will be documented in this file.
 
+## [2.3.15] - 2025-09-09
+
+**重要**：升级了资源清单版本，不兼容老版本。建议重新提审安装包。
+
+### Improvements
+
+- 重构了UniTask扩展库的目录结构和说明文档。
+- 重构了内置文件系统类的加载和拷贝逻辑，解决在一些特殊机型上遇到的偶发性拷贝失败问题。
+- 增加了生成内置清单文件的窗口工具，详情见扩展工程里CreateBuildinCatalog目录。
+- 优化了异步操作系统的繁忙检测机制。
+- (#621) 资源配置页面可以展示DependCollector和StaticCollector包含的文件列表内容。
+- (#627) 优化了资源清单部分字段类型，CRC字段从字符串类型调整为整形，可以降低清单尺寸。
+
+### Fixed
+
+- 修复了构建页面扩展类缺少指定属性报错的问题。
+- (#611)  修复了资源扫描器配置页面，修改备注信息后会丢失焦点的问题。
+- (#622)  修复了纯鸿蒙系统读取内置加密文件失败的问题。
+- (#620)  修复了LINUX系统URL地址转换失败的问题。
+- (#631)  修复了NET 4.x程序集库Math.Clamp导致的编译错误。
+
+### Added
+
+- 新增了支持支付宝小游戏的文件系统扩展类。
+
+- 新增了支持Taptap小游戏的文件系统扩展类。
+
+- 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
+  /// <summary>
+  /// 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 
+
+  ```csharp
+  /// <summary>
+  /// 自定义参数：初始化的时候缓存文件校验最大并发数
+  /// </summary>
+  public int FileVerifyMaxConcurrency { private set; get; }
+  ```
+
+- (#623)  内置构建管线新增构建参数：StripUnityVersion 
+
+  ```csharp
+  /// <summary>
+  /// 从文件头里剥离Unity版本信息
+  /// </summary>
+  public bool StripUnityVersion = false;
+  ```
+
+- 可编程构建管线新增构建参数：TrackSpriteAtlasDependencies
+
+  ```csharp
+  /// <summary>
+  /// 自动建立资源对象对图集的依赖关系
+  /// </summary>
+  public bool TrackSpriteAtlasDependencies = false;
+  ```
+
+- (#617) 新增资源收集配置参数：SupportExtensionless
+
+  在不需要模糊加载模式的前提下，开启此选项，可以降低运行时内存大小。
+
+  ```csharp
+  public class CollectCommand
+  {
+      /// <summary>
+      /// 支持无后缀名的资源定位地址
+      /// </summary>
+      public bool SupportExtensionless { set; get; }  
+  }
+  ```
+
+- (#625) 异步操作系统类新增监听方法。
+
+  ```csharp
+  class OperationSystem
+  {
+      /// <summary>
+      /// 监听任务开始
+      /// </summary>
+      public static void RegisterStartCallback(Action<string, AsyncOperationBase> callback);
+          
+      /// <summary>
+      /// 监听任务结束
+      /// </summary>
+      public static void RegisterFinishCallback(Action<string, AsyncOperationBase> callback);
+  }
+  ```
+
+  
+
