# Migration Notes

YMhut Box 2.x migrates user settings into `%LOCALAPPDATA%\YMhut Box\WinUI\settings.json` on first launch.

The current release line runs as a native WinUI 3 app. Tool metadata, navigation, recent-tool records, settings, logs and update checks are handled by C#/.NET services.

Older app data is imported as a compatibility step and is not required for new installs.
