Turn off the reminder function magento background notification

My magento website: lovely fridge magnet || foot locker 


Each into the the magento background, and always will pop up a dialog box, the latest news prompted magento (notification), the updated version.

This feature, shut down the open position:

system -> configuration -> advanced -> advanced -> Mage_AdminNotification

Set to disable, you can close.

Magento Mage_AdminNotification
If magento close the notification of this feature, I suggest that often go to magento official website look magento News. In case a major bug, released a new version, and you did not receive notice in magento, would not the cups.
