[#82049858] Removing Address from the required params
[#82039224] changed is now a filter on the members
The values for this optional parameter are true or false. If true is selected then the members who have a changed flag of 'true' will be returned. (The same thing for changed set to false.)
[#82049858] Created a new model for PUT on member/{member_slug}/
This makes sense so we are not wanting to let address changes occur via PUT. Changing NewMember to not have the address field affected the POST so this seems like the best choice.
