Subject: [PATCH 03/24] Listen for page control changes by default on
 explicitly set page controls

Technically, this would be a breaking change as current implementations don't expect ImageSlideshow to listen for `.valueChanged` on a PageControl they set themselves. That said, this would be a nice addition so that users of ImageSlideshow don't have to implement this logic themselves.

@@ -23,14 +23,14 @@ ImageSlideshow is available through [CocoaPods](http://cocoapods.org). To instal
 it, simply add the following line to your Podfile:
 
 ```ruby
-pod 'ImageSlideshow', '~> 1.8.3'
+pod 'ImageSlideshow', '~> 1.9.0'
 ```
 
 ### Carthage
 To integrate ImageSlideshow into your Xcode project using Carthage, specify it in your Cartfile:
 
 ```ruby
-github "zvonicek/ImageSlideshow" ~> 1.8.3
+github "zvonicek/ImageSlideshow" ~> 1.9.0
 ```
 
 Carthage does not include InputSources for external providers (due to dependency on those providers) so you need to grab the one you need from `ImageSlideshow/Classes/InputSources` manually.
