 ###Getting video information
 
@@ -94,6 +83,12 @@ Install
 
 This will install this node module along with the latest version of [youtube-dl][] into your module folder. It will also create a symlink to youtube-dl so you run it from the command line.
 
+
+### API Change
+
+Note that the API has changed in version 1.1.0. It now uses emitters to handle the download, progress, and finished events. I'm sorry for any of the invonvenience this may have caused but I'm new at this node.js thing and I just found out emitters are the best way to do this.
