 # Change Log
 
+## Version 3.0.0
+* Refactor
+    * Move the logic for the typhoeus request out of the individual trackers in Tracker to hide the complexity.
+    * Create Tracker to encapsulate the common logic in Backlink, Tracker, and Rank.
+    * Have each file declare it's dependencies, so that it is simple to use a la carte.
+* Fix google backlink and index. The search API is deprecated and the new API is annoying to setup, so webscraping has been brought back.
+* Make requires consistent.
+* API Breakages
+    * Tracker was renamed to Trackers and a new Tracker file was created that represents a different object.
