Where latest UPS shipping module?

I have a client with an old version of ZenCart who does not want to upgrade. The UPS shipping estimator does appear to give same results as UPS rate charts on UPS website. How can I check how old their shipping module is and where to get the latest UPS shipping module? Or is the mis-estimation due to something else?

I did a search under "Contributions", but did not find anything.

Oh, what I meant was they don't want to upgrade "right now". They say it would make more sense to "upgrade when 1.3.8" comes out. But perhaps they can upgrade just the shipping module for the time being.

There, that sounds a bit better.

What version are they running now?

I'm curious as to how the shipping estimator for UPS works. Does the shipping estimator makes XML API calls to the UPS website to determine the rates at runtime? Or are all the rate tables stored in the ZenCart database/PHP?
