What

A subagent is a helper Claude starts to work on part of a task. When a subagent is stopped, killed or fails, Claude Code now removes the items still waiting on its behalf and gives a reason, either that the subagent was killed or that it was stopped. Before, the items were removed without any reason.

Why

This could matter for permission prompts left hanging after the subagent they belonged to is gone.
