In-Depth Technical Analysis

Background

Long Codex turns often need mid-flight steering—waiting for a full response or killing the process wastes context. 0.158.0 hardened MCP OAuth and exec-server tokens; 0.159.0 targets interruptibility and review UX.

What shipped

v0.159.0 adds opt-in instant_interrupt (#48135/#48141), compact welcome/headers, dismiss-on-close warnings (k to keep), scroll-while-planning, richer Mermaid, and item-anchored thread/items/list pagination (#48151). Windows suppresses stray consoles; .aws protected under writable roots; macOS sandbox TLS/proxy fixes.

Benchmarks

No public SWE-bench numbers in the notes. Signal: ~89 commits / 300 files vs v0.158.0. Validate interrupt success and MCP spawn behavior on your stack.

Get started

npm i -g @openai/[email protected] or grab assets from the release. Note removal of tui.prompt_suggestions and the bundled plugin-creator skill.
