Codex alpha updates continue, with a related log-safety fix

openai/codexJun 28, 2026 · 15d ago

0.143.0-alpha.29 was released on June 28, 2026 as a pre-release. The public note only confirms the version and release, so no specific new feature or behavior change can be verified from it.

Several nearby 0.143.0 , from alpha.27 through alpha.34, appeared around the same period, which points to fast ongoing changes. A nearby stable-line release, 0.142.5, fixed a logging issue so full would not be written into trace logs.

A separate community signal raised a possible concern: Codex may behave worse when cluster around 516. The available details do not show whether 0.143.0-alpha.29 fixes that concern or introduces any new one.
