Phocas tracks the history of changes to database designs by automatically creating a new version of the design each time it is saved or when the database is built. You can revert to a previous version if you need to. You can revert to a previous version if you need to.

In Designer, click the **Versions** tab. The **Versions** tab lists all previous iterations of the database design. On the left you can see the last build date and the time the version was saved, along with the option to show the changes. On the right, you can see the status of the build.

## Revert to a previous version
