What
An unhandled rejection is an error in code running in the background that nothing in the program caught. When one of these makes Claude Code shut down, the shutdown now carries a stated cause, "unhandled_rejection". Before, the shutdown happened without saying why.
Why
A shutdown that names its cause makes crashes easier to tell apart and diagnose.
