# Restore an earlier dashboard version

> Use History in the Mammoth dashboard editor to preview any earlier version of a dashboard, see who made it and from which prompt, and restore it as current.
>
> Applies to: Roles: Anyone who can edit the dashboard. Where: Dashboard editor › History

Every change to a dashboard is kept as a version you can preview and restore from **History** in the [dashboard editor](https://mammoth.io/docs/learn/dashboards/editor/) header, next to **Undo** and **Redo**.

## Preview and restore earlier versions with History

1. Click **History**. Each version shows a thumbnail, a label, when it was made, and the prompt that made it. Tags mark the **Current** version and versions that are **Undone** or **Ahead** of where you are.
2. Click a version to preview it. A banner reads "Viewing an earlier version" (or "Viewing the original version"), with who made it and when.
3. Click **Restore** to make it current, or **Back to current** to close the preview.

A version from before you swapped the dashboard's data shows "This version used a different dataset". It isn't previewed, because drawing it against the current data would show the wrong numbers.

| Message | What it means |
| --- | --- |
| "Couldn't load that version." | The version can't load. |
| "Someone else changed this dashboard — we've refreshed it. Please try that again." | Someone changed the dashboard while you were restoring. Try again. |
