What

A background session is a Claude Code session that keeps running without a terminal attached. When the connection used to reach one is rejected, either because authentication did not match or because a reply was refused, the session now records that the rejection happened. Before, the rejection was only logged.

Why

Keeping a record suggests Claude Code can now act on a rejected connection later, rather than only logging it.
