Background updates for Codex CLI without blocking startup

[Eiji-Kudo]

Codex CLI currently surfaces updates at startup and users need to decide whether to update before continuing, or run codex update manually.

It would be useful to have a Claude Code-like background update flow:

• check for updates without interrupting startup
• download/install the next version in the background when possible
• keep the current session on the current binary
• apply the updated version on the next launch
• only notify prominently if the background update failed or requires manual action

This is different from disabling update checks or adding a manual codex update command. The goal is to keep Codex current while avoiding a startup interruption and preserving user momentum.

I could not find an existing discussion or issue specifically about this background update flow. The closest items I found were about the manual codex update command, disabling update prompts, update check frequency, and update prompt wording, which seem adjacent but not the same request.

Totally agree, claude does this and since this software evolves so quickly its mandatory, my attention is limited, updating is a no brainer, no need to ask.
