+*   Changed how validation error translation strings are fetched: The new behaviour
+    will first try the more specific keys, including doing locale fallback, then try
+    the less specific ones.
+    
+    For example this is the order keys will now be tried for a `blank` error on a
+    `product`'s `title` attribute with current locale set to `en-US`:
+ 
+        en-US.activerecord.errors.models.product.attributes.title.blank
+        en-US.activerecord.errors.models.product.blank
+        en-US.activerecord.errors.messages.blank
+        
+        en.activerecord.errors.models.product.attributes.title.blank
+        en.activerecord.errors.models.product.blank
+        en.activerecord.errors.messages.blank
+        
+        en-US.errors.attributes.title.blank
+        en-US.errors.messages.blank
+        
+        en.errors.attributes.title.blank
+        en.errors.messages.blank
