### `brew upgrade codex` isn't upgrading me

If you're running Codex v0.46.0 or older, `brew upgrade codex` will not move you to the latest version because we migrated from a Homebrew formula to a cask. To upgrade, uninstall the existing oudated formula and then install the new cask:

```bash
brew uninstall --formula codex
brew install --cask codex
```

After reinstalling, `brew upgrade --cask codex` will keep future releases up to date.
