+- (#163) 修复了Unity2019版本编译报错的问题。
+- (#167) 修复了初始化时每次都会提示文件验证失败日志。
+- (#171) 修复了IsNeedDownloadFromRemote里缺少判断依赖的资源是否下载 。
+
+### Added
+
+- 资源收集器里增加了AddressDisable规则。
+
+- 资源收集器里FilterRuleData结构体增加了多个备选字段。
+
+  ```c#
+  public struct FilterRuleData
+  {
+      public string AssetPath;
+      public string CollectPath;
+      public string GroupName;
+      public string UserData;
+  }
+  ```
+
+### Changed
+
+- 可以设置自定义参数DefaultYooFolderName。
+
+- 资源配置界面的分组不激活时，不再进行配置检测。
+
+- SBP构建管线增加新构建参数用于修复图集资源冗余问题。
+
+  ```c#
+  public class SBPBuildParameters
+  {
+      /// <summary>
+      /// 修复图集资源冗余问题
+      /// </summary>
+      public bool FixSpriteAtlasRedundancy = false;
+  }
+  ```
+
 ## [1.5.4-preview] - 2023-08-25
 
 优化了资源清单文件构建速度（极大提升构建体验）（感谢yingnierxiao同学）。
