Magento has released a new update for Magento which includes the SUPEE-6482 Patch Bundle. See also my post for the magento version 220.127.116.11
I have performed successfully the upgrade thru Magento Connect Manager. Just wait a least 5 minutes.
Note: I recommend you to perform the upgrade on a test environment first.
Note that the bug I had into the previous release seems to be fixed : see my previous article
