Codex 0.159.0 introduces an opt-in instant_interrupt setting that lets new input steer the agent during model responses and long-running code-mode calls. App-server clients can also paginate thread history from a specific item. The release fixes Windows MCP process launches and preserves explicit filesystem denials when preparing approved commands.
