Xcode 8 recommend me to change the min iOS Deployment Target from 7.1 to 8.0
<p>When I use the Xcode 8 beta(8S128d) to open my project,it recommend me to change the min iOS Deployment Target to 8.0 instead 7.1.
And I found that there is no option less than 8.0 in the iOS Deployment Target list.</p>

<p>So, does it mean that I no longer need to adjust my project for iOS 7.x or less?</p>
