Codex CLI v0.159.0 Release Notes — What's New

New Features

Opt-in instant_interrupt lets new input steer Codex during model responses or long-running code-mode calls. (#48135, #48141)
New sessions get a compact welcome screen and consistent headers, with occasional tips during and after turns. (#48513, #48562, #48352)
The warnings viewer dismisses reviewed warnings when closed; press k to keep one for later. (#48205, #48206)
You can scroll the transcript while deciding whether to implement a plan. (#48805)
Native Mermaid rendering supports more flowchart edges, labels, and node groups. (#48814, #48895)
App-server clients can paginate thread history from a specific item. (#48151)

Bug Fixes

Windows launches avoid stray console windows for MCP servers, code-mode hosts, and piped commands; restrictive launchers can fall back to embedded mode. (#48138, #48238, #48483, #48491)
Copying transcript selections preserves Markdown tables, formatting, and significant whitespace. More terminals now copy automatically on selection. (#48548, #48549, #48469)
Blank sessions retain drafts when switching tasks, and threads can be archived and listed before their first turn. (#48628, #48828, #48199)
Local ChatGPT sign-in opens the browser reliably; onboarding also provides a shortcut to copy the login link. (#48502, #48544)
Approved commands retain explicit filesystem denials, and .aws directories are protected by default under writable roots. (#48155, #48176)
Fixed macOS TLS access in network-enabled sandboxes and remote environments that require proxy access. (#48565, #48198)

Chores

Removed automatic follow-up prompt suggestions and the tui.prompt_suggestions setting. (#48621)
Removed the bundled plugin-creator skill. (#48604)
