The archived package can still migrate existing environments and restore older configurations, but the project is no longer maintained. As operating systems, cores, and configuration formats continue to change, the archived client will not receive ongoing compatibility updates.
For new devices, prefer actively maintained clients such as Clash Plus, Clash Verge Rev, FlClash, or Clash Nyanpasu. Before migrating, record the subscription URL, policy choices, and local overrides, then restore them one by one in the new client rather than assuming every field is fully compatible.
