The Squiz website tells us that your can update the Squiz Matrix product at the click of a button, provided you have a support agreement:

Can someone confirm that this feature exists for the Squiz Matrix product.
That page talks about our automated upgrade scripts. It's not a button, but it is pretty easy. More info (and links to documentation) can be found at: http://matrix.squizsuite.net/subscriptions/
