What's up with the .NIB -> .XIB?

iphone, nib, objective-c, xcode

Solution

XIB's are very cool. they are basically an un-compiled NIB (in XML format if memory serves me)

during the build process they are converted to NIB's to be deployed in the final product.

Problem

What's up with the NIB->XIB change somewhere between XCode 3.0 to 3.1? Is there any difference with this name change that I should know while I go through tutorials that mention nothing but the .nib file?
