 # 업데이트 이력
 
+## 2026-06-23 / v4.0.7 — 덱 목록 JS 캐시·init 오류 수정
+
+### 수행 작업
+- 운영 `deck-favorites.js` 구버전( `init` 없음) + CDN JS 캐시로 `UaDeckFavorites.init is not a function` 발생 → 덱 로드 중단
+- `deckHistory.html`·`preset.html`: 스크립트에 `?v=4.0.7` 캐시 무효화, `init` 없을 때도 `loadDecks` 실행되도록 방어 코드
+
 ## 2026-06-23 / v4.0.6 — CSS 캐시·배포 반영 수정
