+## [0.37.1] — 2026-04-23
+
+### ✨ Highlights
+- `planet.sh` 后端重启链路修复 `uvicorn --reload` 残留 worker 场景，`restart` 现在能真正替换旧实例
+
+### 🔧 Improvements
+- 收口后端清理逻辑，统一按 `uvicorn` 进程、端口占用进程和进程组执行清理，减少 reload 场景漏杀分支
+
+### 🐛 Fixes
+- 修复部分机器执行 `./planet.sh restart --allow-lan` 后后端仍停留旧实例，导致 `/api/v1/visualization/geo/compute-centers` 返回 `404` 的问题

 ## Timeline
 
 | Version | Type | Branch | Commit | Summary |
 | --- | --- | --- | --- | --- |
+| `0.37.1` | bugfix | `dev` | `pending` | 修复 `planet.sh` 在 `uvicorn --reload` 场景下未清理旧 worker 的问题，避免后端重启后仍停留旧实例并导致算力中心聚合接口 404 |
 | `0.37.0` | feature | `dev` | `pending` | Earth 连线系统从巡航语义中完全解耦为通用 callout connector，统一桌面/移动端对象级锚点、临界区锚点滑动与稳定巡航展示链路 |
 | `0.36.0` | feature | `dev` | `pending` | Earth 新增统一算力中心图层与估算位置展示，继续收口拖拽交互，并补充 AI Provider 指纹与 WSL 局域网访问支撑 |
 | `0.35.1` | bugfix | `dev` | `pending` | 收口 Earth 桌面 HUD 与移动端抽屉的统一统计绑定机制，修复态势统计在图层切换后的同步遗漏 |
