Apple's engineers have been very busy these days because last night the company released an update for its developers OS X Mountain Lion Developer Preview 3, Mac OS X Lion 10.7.4 build 11E53 and a new version of Xcode 4.4. Of the 3, only OS X Mountain Lion bring an interesting novelty and it is represented by an option Do Not Disturb which allows users to block notifications coming through the Notifications Center that will be included in the new version of the operating system.
As soon as this function is activated, it completely blocks the notifications coming from any application in OS X and I think it should make its way into the iOS available in our iDevices. In the past, Apple offered us the option to completely block Push Notifications, but starting with iOS 5, we have to close them manually for each individual application. For now, OS X Mountain Lion is "scheduled" for a summer release, and Mac OS X Lion 10.7.4 should be available before WWDC on June 11.
