How can I compare the current version of a file to past versions of a file?

Select the Differences View. (You can select the menu View -> Differences View)
In the base revision history pick the base revision for the comparison.
In the compare revision history pick the compare revision for the comparison.
In the file browser below you will see the state of all the files which differ from the revision base to the compare revision.
Select files you are interested in and diff them to see the differences.
