 All notable changes to this package will be documented in this file.
 
-## [2.3.1-preview] - 2025-02-25
-
-**资源加载依赖计算方式还原为了1.5x版本的模式，只加载资源对象实际依赖的资源包，不再以资源对象所在资源包的依赖关系为加载标准**。
-
-### Improvements
-
-- 优化OperationSystem的更新机制，异步加载的耗时降低了50%。
-- 优化了Debugger窗口的显示页面，BundleView页面增加资源包的引用列表。
-- 优化了Reporter窗口的显示页面。
-
-### Fixed
-
-- 修复了怀旧依赖模式下，TAG传染不正确的问题。
