If you are looking to just make your LMS current, the update feature tht's built into CiscoWorks will do that for you. If you're looking for offline verification to download and install patches / updates manually, there's an install.log created whenever an update is performed. It's parsed nicely for you if you just go to the GUI (Reference) by selecting Common Services > Software Center > Software Update.

There is also a compilation of the various CiscoWorks applications and version in this document. It is more recent than the FAQ link posted above.

Hope this helps.
