 <ul>
-<li>macOS Ventura (13.0+)를 지원합니다.</li>
-<li>앱 실행 시 아무 동작이 없는 것처럼 보인다는 피드백을 반영하여 실행 직후 맞춤법 검사기 화면을 표시하도록 변경했습니다.</li>
-<li>Dock에 앱을 두고 사용하는 경우를 고려해 Dock에 있는 앱을 클릭했을 때 맞춤법 검사기 화면이 표시되도록 변경했습니다.</li>
-<li>검사 진행 중 확인이 가능하도록 진행률을 표시하도록 추가했습니다.</li>
-<li>맥 내 서비스(Services) 메뉴에서도 맞춤법 검사를 할 수 있도록 추가했습니다. 단축키를 할당하면 아무 곳에서나 선택한 텍스트를 바로 검사할 수 있습니다. 방법: https://github.com/ssut/Matchumbeop/wiki/macOS-서비스-등록-방법</li>
