# list_flight_versions
> List the version history of a Flight, newest first.
List every immutable version of a [Flight](/concepts/flights), newest first. Each update to `source_code`, `requirements_txt`, `config`, `md_token_name`, or `md_secret_names` produces a fresh version. Updates to `name` or `schedule_cron` are metadata-only and do not appear here.

## Description

Use `list_flight_versions` to browse what changed between versions, or to find the version a specific run executed. The corresponding SQL function is [`MD_FLIGHT_VERSIONS`](/sql-reference/motherduck-sql-reference/flights/md-flight-versions).

## Input parameters

| Parameter | Type | Required | Description |
|---|---|---|---|
| `id` | string (UUID) | Yes | The Flight UUID. |
| `limit` | integer | No | Max results to return (default: 100, max: 500). |
