If you mean an audit trail of what software was updated with from and to versions, and when: not that I know of unless you document it.
As mentioned above, you can check the current version several ways. And I will add that if you have used USM to do the updates, that you can probably identify the date of the last update by looking in the USM repository; there is a folder for diagnostic data, and each array should have a file present that was created during the last service (unless it was collected manually since then...).
If you looked at the files on an SP there are probably 'breadcrumbs' that you could pick up there that might help you re-construct an upgrade history, perhaps someone else can provide some insight into that possibility.
