What
A cloud session is a Claude Code session running on Anthropic's servers that can be attached to your computer. Claude Code now has a way to reconnect such a session after a restart, using a device key it keeps and proof held by the session itself. It retries reading the session link several times, waiting longer between tries. If reconnecting fails, it reports "cannot reconnect cloud session".
This is behind a server-controlled switch and a second check.
Why
Restarting Claude Code no longer has to cut off an attached cloud session.
