# Version History

> Inspect saved changes and restore an individual setting.

Open **History** in the Advanced builder. Pending changes show the previous and new values before you save. Saved versions let you review what changed over time.

Select the change you want to reverse and restore that setting. Review the pending edit, save the assistant, and test the affected behavior. For example, restore the previous voice while keeping a prompt revision made in the same version.
