+# Overview of Changes
+
+## 0.3.0
+
+* Factory.debug was broken on ActiveModel based classes, now works with them
+
+* Attributes can be skipped by setting the value to :skip. e.g. crank(:user, :name => :skip) will
+  generate a User instance without calling or assigning anything to the name attribute
+
+* Updated dev environment for latest rspec compatibility (2.6.0)
+
+## 0.2.0 
+
+Changes between version prior to this were not tracked here
