The Codex Changelog

Codex’s 0.163.0 prerelease adds Program Status Protocol signals so terminals can distinguish working, done, error, and the kinds of prompts that block an agent—without scraping screens or watching window titles. We explain how the signals latch until you interact, what to expect from terminal integrations, and cover recent changes to managed worktrees, image previews, model catalogs, and WebSocket request limits.

Discover how OpenAI's new Composer predictions and faster steering settings in the Codex desktop app speed up your agent workflows. Learn about eligibility requirements, safety guardrails, and key CLI quality-of-life updates.

A deep dive into Codex 0.162.1 reveals why choosing the new MXC backend doesn't automatically secure your network, alongside the security risks of loopback access in managed environments. Plus, learn about key quality-of-life updates, including instant interrupts, preserved CRLF line endings, and TUI scroll speed customization.

Discover why OpenAI Codex sandboxed commands fail on Windows with os error 32 sharing violations and why the fix missed the 0.162 stable line. Learn how to verify your build via logs and explore practical workarounds ranging from Full Access to prerelease builds.
