Release Notes

New Features - Opt-in instantinterrupt 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.promptsuggestions setting. (48621) - Removed the bundled plugin-creator skill.
