+### Выпуск релиза
+
+1. Поднимите `version` в `package.json` и добавьте раздел `## X.Y.Z` в `CHANGELOG.md`.
+2. После слияния в `main` поставьте тег: `git tag vX.Y.Z && git push origin vX.Y.Z`.
+3. Workflow `release.yml` на `windows-latest` прогонит проверки, соберёт `GetBox-X.Y.Z-portable.exe` и опубликует релиз «GetBox X.Y.Z» с разделом из `CHANGELOG.md`.
