 *SVN*
 
+* Fixed that remote_form_for can leave out the object parameter and default to the instance variable of the object_name, just like form_for [DHH]
+
 * Modify routing so that you can say :require => { :method => :post } for a route, and the route will never be selected unless the request method is POST. Only works for route recognition, not for route generation. [Jamis Buck]
 
 * Added :add_headers option to verify which merges a hash of name/value pairs into the response's headers hash if the prerequisites cannot be satisfied. [Sam Stephenson]
