 Conductor is architecture-agnostic and does not try to force any design decisions on the developer. We here at BlueLine Labs tend to use either MVP or MVVM, but it would work equally well with standard MVC or whatever else you want to throw at it.
 
 ## Installation
 
 ```gradle
-compile 'com.bluelinelabs:conductor:1.1.0'
+compile 'com.bluelinelabs:conductor:1.1.2'
 
 // If you want the components that go along with
 // Android's support libraries (currently just a PagerAdapter):
-compile 'com.bluelinelabs:conductor-support:1.1.0'
+compile 'com.bluelinelabs:conductor-support:1.1.2'
 
 // If you want RxJava/RxAndroid lifecycle support:
-compile 'com.bluelinelabs:conductor-rxlifecycle:1.1.0'
+compile 'com.bluelinelabs:conductor-rxlifecycle:1.1.2'
 ```
