Codex 0.155.1 is a one-commit hotfix restoring `none` as the TUI reasoning-summary default
GitHub·medium signal
Published 2026-09-18T20:03Z, rust-v0.155.1 contains a single fix (#46467): new local TUI sessions again leave reasoning summaries disabled by default, because providers that do not support reasoning summaries were rejecting the requests outright. Explicit reasoning-summary settings are still respected. If you were seeing hard request rejections from a non-OpenAI provider on 0.155.0, this is the cause and the fix.
