  81  Options:
  82  --non-interactive     No interactive questions or confirmations
  83  --allow-unstable      Upgrade even if the version is not marked as stable yet,
  84                        required in non-interactive mode.
  85  --lang=CODE           Set preferred language for CLI output. Defaults to the
  86                        site language if not set. Defaults to 'en' if the lang
  87                        parameter is invalid or if the language pack is not
  88                        installed.
  89  --verbose-settings    Show new settings values. By default only the name of
  90                        new core or plugin settings are displayed. This option
  91                        outputs the new values as well as the setting name.
  92  --is-pending          If an upgrade is needed it exits with an error code of
  93                        2 so it distinct from other types of errors.
  94  -h, --help            Print out this help
