+* Create all necessary build configurations for *Pods.xcodeproj* at the project level. If the user’s project has more than just *Debug* and *Release* build configurations, they may be explicitly specified in the Podfile:  
+`xcodeproj 'MyApp', 'App Store' => :release, 'Debug' => :debug, 'Release' => :release`  
+  If build configurations aren’t specified in the Podfile then they will be automatically picked from the user’s project in *Release* mode.  
+  These changes will ensure that the `libPods.a` static library is not stripped for all configurations, as explained in [#1217](https://github.com/CocoaPods/CocoaPods/pull/1217).
