+- 恢复 WebUI 在接口返回 401 时跳转登录页，避免会话失效后停留在异常状态。([#8903](https://github.com/AstrBotDevs/AstrBot/pull/8903))
+- 保持 Core 版本与 WebUI 静态资源版本同步，修复打包或升级后可能加载旧 dist、资源版本错配的问题。([#8901](https://github.com/AstrBotDevs/AstrBot/pull/8901))
+- 将知识库上下文作为临时 user 内容注入，修复模型请求中知识库上下文角色不准确的问题。([#8904](https://github.com/AstrBotDevs/AstrBot/pull/8904))

+
+## What's Changed (EN)
+
+### Bug Fixes
+
+- Restored the WebUI login redirect when API requests return 401, preventing expired sessions from staying in a broken state. ([#8903](https://github.com/AstrBotDevs/AstrBot/pull/8903))
+- Kept Core and WebUI static asset versions in sync, fixing stale dist loading and asset version mismatches after packaging or upgrades. ([#8901](https://github.com/AstrBotDevs/AstrBot/pull/8901))
+- Injected knowledge base context as temporary user content, fixing the role used for knowledge context in model requests. ([#8904](https://github.com/AstrBotDevs/AstrBot/pull/8904))
