Software updates for 2007 XK's..?

I factory ordered my gorgeous 2007 Salsa Red XK convertible in June 2006. This car was delivered on August 31, '06 (Thanks!, Jaguar). I have read posts on other sites that say that this car has had software updates. I am taking the fun car in for service very soon. The service manager at my dealership says that he is unaware of any software updates. Help...confused by the different statements....??

Too far from Tucson, Too far from San Antonio. Need local club.
