Codex 0.153.4
A hotfix restores Astra to Codex's bundled model picker as the default and limits its async-question guidance to sessions where that tool exists.
Codex 0.153.4 is a hotfix that fixes Astra's visibility in the bundled model picker and makes it the bundled default when no model is explicitly configured. It also updates Astra's guidance so it only uses asynchronous questions when that tool is available in the session.
Full details are in the release notes.
