Codex CLI 0.159.0: Opt-in instantinterrupt lets new input steer Codex during model responses or long-running code-mode calls.

Key changes

Opt-in `instant_interrupt` lets new input steer Codex during model responses or long-running code-mode calls.
New sessions get a compact welcome screen and consistent headers, with occasional tips during and after turns.
The warnings viewer dismisses reviewed warnings when closed; press `k` to keep one for later.
You can scroll the transcript while deciding whether to implement a plan.
Native Mermaid rendering supports more flowchart edges, labels, and node groups.
App-server clients can paginate thread history from a specific item.
Windows launches avoid stray console windows for MCP servers, code-mode hosts, and piped commands; restrictive launchers can fall back to embedded mode.
Copying transcript selections preserves Markdown tables, formatting, and significant whitespace. More terminals now copy automatically on selection.
