Editor version history saves snapshots of page content while you design.
Open version history

In the designer toolbar, click the version history icon. You see numbered versions (V1, V2, and so on).
Actions
- Preview — See how a past version looked.
- Restore — Replace current canvas content with that version.
- Delete — Remove a saved version you no longer need.
This is content history inside the designer. Deploy versions on the Publish screen are separate published builds. See Auto-publish and deploy versions.
