      "Version: v3.241.0",

      "json (value for --output) (required): Emit an object containing `result`, `duration`, and per-operation-kind counts in `summary`.",
      "Docs conflict: The current Pulumi CLI reference is generated for v3.268.0 and documents `--json` for serialized preview diffs, operations, and overall output; it does not document `--output`. This differs from the v3.241.0 release note, so that newer reference was not used to describe the new flag."
