openai/codex released two tagged pre-releases in window: 0.148.0-alpha.19 on 15 Aug 2026 and 0.148.0-alpha.20 on 16 Aug 2026, both published by github-actions. Per-tag changelogs are not exposed on the GitHub release pages in a loadable form, so specific feature notes for each cut are not verifiable; only version, commit and ship date are confirmed against the official release feed.

Why it matters

OpenAI continues the 0.148 alpha cadence of Codex CLI ahead of an expected stable cut; tracking the alpha trains is the only public signal of near-term CLI changes.

Importance: 3/5
