 # 업데이트 이력
 
+## 2026-06-23 / v4.0.8 — nginx 정적 캐시·deck-favorites 배포 수정
+
+### 수행 작업
+- 운영 HTML이 v4.0.6·JS가 CDN `immutable` 구버전으로 남아 `init` 오류 지속
+- `docker-compose.prod.yml`: `nginx/default.conf` 볼륨 마운트 추가
+- nginx: HTML·`deck-favorites.js`·`api.js` `no-cache`, JS `immutable` 제거
+- `script/deck-favorites-shim.js`: 구버전 JS에 `init`/`forget` 폴리해
+- `docs/deploy.md`: 호스트 vs 컨테이너 vs Cloudflare 3단계 검증 명령 추가
+
