Whenever you save a version of your dashboard, a copy of that version is saved so that previous versions of your dashboard are not lost. A list of these versions is available by entering the dashboard settings and then selecting **Versions** in the left side menu.

**Note**  
The most recent 20 versions of a dashboard are saved.

The dashboard version history feature lets you compare and restore to previously saved dashboard versions.

**Comparing two dashboard versions**

To compare two dashboard versions, select the two versions from the list that you wish to compare. Click **Compare versions** to view the diff between the two versions. This brings up the version diff view. By default, you’ll see a textual summary of the changes.

If you want to view the diff of the raw JSON that represents your dashboard, you can do that by clicking the **View JSON Diff** button at the bottom.

**Restoring to a previously saved dashboard version**

If you need to restore to a previously saved dashboard version, you can either select the **Restore** button on the right of a row in the dashboard version list, or select the **Restore to version *<x>*** button in the diff view. Selecting either of these will prompt you to confirm the restoration.

After restoring to a previous version, a new version will be created containing the same exact data as the previous version, only with a different version number. This is indicated in the **Notes column** for the row in the new dashboard version. This ensures your previous dashboard versions are not affected by the change.
