 All notable changes to this package will be documented in this file.
 
+## [1.3.4] - 2022-11-04
+
+### Fixed
+
+- (#29)修复了EditorHelper中根据guid找uxml有时候会出错的问题。
+- (#37)修复了在修改GroupName和GroupDesc时，左侧Group栏显示没刷新的问题。
+- (#38)修复了工程里没有shader的话，SBP构建会报异常的问题。
+
+### Added
+
+- 新增了AssetsPackage.CheckPackageContentsAsync()方法
+
+  ```c#
+  /// <summary>
+  /// 检查本地包裹内容的完整性
+  /// </summary>
+  public CheckPackageContentsOperation CheckPackageContentsAsync()
+  ```
+
+### Changed
+
+- 优化了HostPlayMode的初始化逻辑，优先读取沙盒内的清单，如果不存在则读取内置清单。
+
+- 重写了文件的加密和解密逻辑。
+
+  ```c#
+  public interface IDecryptionServices
+  {
+      /// <summary>
+      /// 文件偏移解密方法
+      /// </summary>
+      ulong LoadFromFileOffset(DecryptFileInfo fileInfo);

+- 编辑器模拟模式
+
+  每次启动调用EditorSimulateModeHelper.SimulateBuild()方法，都会在底层执行一次模拟构建（Simulate Build）。
+
+  如果参与构建的资源对象数量级很大的话则会有卡顿现象，可以通过直接指定已有的清单路径来避免每次都重复执行模拟构建。
+
+- 单机运行模式
+
+  在初始化的时候，会直接读取内置清单文件（StreamingAssets文件夹里的文件），最后根据加载的清单去验证沙盒里缓存的文件。
+
+- 联机运行模式
+
+  该模式下，每个package都会在沙盒里保留一份清单，当有更新的时候采用覆盖的方式存储。
+
+  在初始化的时候，会优先从沙盒里加载清单，如果沙盒里不存在，则会尝试加载内置清单并将其拷贝到沙盒里。最后根据加载的清单去验证沙盒里缓存的文件。
+
+  **注意**：如果沙盒清单和内置清单都不存在，初始化也会被判定为成功！

-对于偏单机但是也有资源热更需求的项目。当玩家本地网络不稳定或无网络的时候，我们又不希望玩家卡在资源更新步骤而不能正常游戏。所以当玩家本地网络有问题的时候，我们可以跳过资源更新的步骤。
