What
Claude Code reuses open network connections instead of opening a new one for every request. It now keeps a separate set of reusable connections for each client, so connections for different customers do not mix.
For one of its HTTP clients, Claude Code reads an idle limit and closes a connection that has been unused for that long. It reuses a stored connection only when both the idle limit and the security (TLS) settings match. Before, it reused a connection whenever the security settings matched.
Why
This changes when connections are reused and when idle ones are closed.
