What is the strong property attribute

I am using the Xcode beta for developers, and am noticing some subtle differences. Among them is a new attribute for declared properties.

@property(strong)IBOutlet NSArrayController *arrayControl;

My question is: what does the strong attribute mean?? Does it replace some older one, or is it something entirely new? I have searched through google and the developer documentation and havent been able to find anything. Until i know what it is i am hesitant to use it.

Thanks in advance

As we know, we cannot release any object in an ARC-based project in iOS 5. So when we want to retain any object for further use at a later stage and don't want ARC to remove the object from memory, then we set the property for the object as "Strong".
