+## [2.3.9] - 2025-05-13
+
+### Improvements
+
+- 增加了YOO_ASSET_EXPERIMENT宏，用于控制实验性代码的开关。
+- 构建管线目前会输出构建日志到输出目录下，方便查看引擎在构建时主动清空的控制台日志。
+- 优化了收集器tag传染扩散逻辑，避免Group里配置了Tag导致的无意义的警告信息。

+
+### Fixed
+
+- (#528) 修复了AssetDependencyDatabase在查询引擎资源对象是否存在的时效问题。

+      /// 销毁资源系统
+      /// </summary>
+      public static void Destroy();
+  }
+  ```
+
+- 新增了SBP构建管线的构建参数
+
+  ```csharp
+  /// <summary>
+  /// 从AssetBundle文件头里剥离Unity版本信息
+  /// </summary>
+  public bool StripUnityVersion = false;
+  ```
+
+- 新增了构建错误码：BuiltinShadersBundleNameIsNull 
+
+## [2.3.8] - 2025-04-17
+
+### Improvements
+
+- 扩展工程里增加了“图集丢失变白块的解决方案”的相关代码。
+
+### Fixed

+
+### Improvements
+
+- (#526) 运行时资源清单的哈希值验证兼容了MD5和CRC32两种方式。
+- (#515) 优化了资源路径大小写不敏感的逻辑代码，减少字符串操作产生的GC。
+- (#523) UnloadUnusedAssetsOperation方法支持了分帧处理。
+
+### Fixed
+
+- (#520) 修复了UWP平台获取WWW加载路径未适配的问题。
+
+### Added
+
+- 新增了文件系统初始化参数：INSTALL_CLEAR_MODE
+
+  ```csharp
+  /// <summary>
+  /// 覆盖安装清理模式
+  /// </summary>
+  public enum EOverwriteInstallClearMode
+  {
+      /// <summary>
+      /// 不做任何处理
+      /// </summary>
+      None = 0,
+   
+      /// <summary>
+      /// 清理所有缓存文件（包含资源文件和清单文件）
+      /// </summary>
+      ClearAllCacheFiles = 1,
+   
+      /// <summary>
+      /// 清理所有缓存的资源文件
+      /// </summary>
+      ClearAllBundleFiles = 2,
+   
+      /// <summary>
+      /// 清理所有缓存的清单文件
+      /// </summary>
+      ClearAllManifestFiles = 3,
+  }
+  ```
+
+- 新增了初始化参数：BundleLoadingMaxConcurrency
+
+  ```csharp
+  public abstract class InitializeParameters
+  {
+      /// <summary>
+      /// 同时加载Bundle文件的最大并发数
+      /// </summary>
+      public int BundleLoadingMaxConcurrency = int.MaxValue;
