Unclear What the new end-of-run note looks like is not stated.
What
When a shell command running in the background finishes, Claude Code adds a note to its output. It used to write a plain line saying [killed] or [exited with code N]. It now passes whether the command was killed, or its exit code, to a separate step that records the ending, so the note may look different.
Why
This changes how the end of a background command shows up in its output.
