+## What's Changed
+
+### 修复
+
+- 将 WebUI 项目升级改为后台任务执行，避免关闭或刷新前端页面导致升级请求被取消。
+- 调整升级流程为先下载并校验 WebUI 与 Core 两个更新包，再统一应用，降低下载失败导致文件半更新的风险。
+- Core 更新包优先从 AstrBot Registry 下载，失败时回退到 GitHub zipball。
+- WebUI 在升级重启期间会轮询启动时间，并在重启完成后使用 cache-buster 进行全量刷新，减少旧前端缓存残留。
+
+### 构建
+
+- 调整 Hatch artifact 配置，确保 sdist 与 wheel 都包含打包后的 Dashboard 资源。
+- Release workflow 增加 Core 更新包构建与 Registry 上传。

+
+## What's Changed (EN)
+
+### Bug Fixes
+
+- Changed WebUI project updates to run as backend tasks, preventing updates from being cancelled when the frontend is closed or refreshed.
+- Made the update flow download and verify both WebUI and Core packages before applying files, reducing partial-update risk after download failures.
+- Prefer AstrBot Registry for Core update packages, with GitHub zipball fallback.
+- During update restarts, WebUI now polls backend start time and performs a cache-busted full refresh after restart completion to avoid stale frontend assets.
+
+### Build
+
+- Updated Hatch artifact configuration so both sdist and wheel include bundled Dashboard assets.
+- Added Core package build and Registry upload steps to the release workflow.
