The Codex changelog migrates internal GPT-5.4 selections to GPT-5.6 Terra and Luna, restores Guardian auto-review's prior policy and tool behavior after a prompting regression, and refreshes the bundled OpenAI Docs skill. Startup and large-context overhead dropped via concurrent skill/plugin discovery and more efficient remote compaction, and packaged ripgrep is now 15.2.0. GPT-5.4 and 5.4-mini leave Codex for ChatGPT-signed-in sessions on August 31 but stay on the API. If you depend on them, pin an API key.
