Version notes worth knowing

  • WSL1: supported through Codex 0.114. From 0.115 the Linux sandbox uses bubblewrap, so WSL2 is required (source: OpenAI’s Windows docs).

Questions people ask

Why are GitHub release tags named rust-v...?

The Codex CLI is written in Rust, and its GitHub release tags use the rust-v prefix, for example rust-v0.162.1. The number after it is the version that codex --version reports.

Should I update right away?

For daily work, updating within a few days is reasonable. If Codex runs in CI, pin a version and update deliberately after reading the release notes.
