+# Changelog
+
+本文件记录 `ShrinkInstaller` 的包内变更。
+
+## [0.2.5] - 2026-09-05
+
+### Fixed
+
+- 按 SemVer 比较已安装版本与目录版本；已安装较新版本不再被误判为旧版本，也不会提供降级操作。
+- 更新内置包目录，使版本与当前 ShrinkSDK 模块清单一致。
+
+## [0.2.4] - 2026-08-28
+
+### Changed
+
+- 目录切换到 `ShrinkEventBus 2.0.1` 及其精确依赖链，常用完整套件仍只安装四个直接根。
+
+## [0.2.3] - 2026-08-28
+
+### Changed
+
+- 目录固定到 App Core 0.1.3、Context App Adapter 0.1.4、Starter Basic 0.2.1、DataSaver 2.2.2、ModFramework 0.2.3 及对应 Integration 稳定版本。
+- 常用完整套件继续只安装 Starter、Context EventBus Adapter、ModFramework 与 Tutorial 四个直接根，并固定 UniTask revision。
