Looking at Project Versions

In the History area you can look at the versions of your project. Each version corresponds to a script that created it, and is labeled with the check-in comment from that script and a unique script id.

To view the details of a version:

Select any version to view the files affected by this check-in in the Details pane below
Double-clicking a file in the Details pane will launch the file in the visual differ where you can see the differences
From the Details pane you can choose to save copies of selected files to a specified location

To view changes made since a certain version:

Select the version from which you want to start
Select Show changes since this script... from the Selection menu or Context menu
The list of files that have changed since this version will be listed in the Details pane.
Double-click on any of the files in the list to view the differences.
From the Details pane you can choose to save copies of selected files to a specified location

Calling history from the Files Tab

Another approach for viewing history is to first select a file (or files) in the Files tab, and click the Show History button. You'll be shown all the scripts that changed the selected file/s. You can view these scripts, compare versions of the file, and save them under different names.
