+# Changelog
+
+이 문서는 LaunchingView의 릴리즈 변경 사항을 기록합니다.
+
+## Unreleased
+
+- 아직 릴리즈되지 않은 변경 사항은 여기에 기록합니다.
+
+## 0.9.1 - 2026-05-17
+
+### Added
+
+- 강제 업데이트와 종료형 공지를 앱 종료 대신 차단 화면으로 표시하는 `BlockingLaunchView` 흐름을 추가했습니다.
+- fetch 취소, fetch error dismiss 후 재조회, optional update action, notice dismiss URL open 흐름을 Swift Testing 테스트로 보강했습니다.
+- README에 LaunchingView의 목적, 동작 방식, 주요 컴포넌트, 설정 포인트를 한글로 보강했습니다.
+
+### Changed
+
+- `LaunchingService` 의존성을 `0.9.2`로 업데이트했습니다.
+- The Composable Architecture를 `1.25.5`로 업데이트했습니다.
+- Swift tools를 `6.1`로 올렸습니다.
+- 최소 지원 플랫폼을 iOS 16.0, macOS 13.0으로 상향했습니다.
+- `ViewStore` 기반 관찰을 제거하고 `@ObservableState`, `@Presents`, `Perception` 기반 Store 관찰로 전환했습니다.
+- DocC 배포 워크플로가 `swift-man/docs` 저장소의 `main` 브랜치에 `LaunchingView/` 경로로 배포하도록 정리했습니다.
+
+### Fixed
+
+- fetch 실패 alert를 표시하기 전에 optional update alert와 notice alert 상태를 정리해 여러 alert binding이 동시에 활성화될 수 있는 문제를 방지했습니다.
+- fetch 작업 취소 시 사용자에게 fetch error alert가 표시되지 않도록 취소 경로를 별도로 처리했습니다.
+- SwiftUI view 재생성 중 Store 상태가 유실되지 않도록 Store 소유권을 안정화했습니다.
+
+## 0.9.0 - 2026-05-17
+
+### Changed
+
+- Launching reducer의 부수 효과를 TCA dependency 기반으로 분리했습니다.
+- URL open 동작을 `@Dependency(\.openURL)`로 주입하도록 정리했습니다.
+- `LaunchingService` 테스트 의존성을 안전하게 격리했습니다.
+- XCTest 기반 테스트를 Swift Testing 기반으로 전환했습니다.
