* allows ib_spec attrs to be filtered in update
This change will allow the ib_spec entries to be be filtered on a change
object by setting the update keyword to false. The default value for
update is true. When the update keyword is set to false, the keyed
entry will be removed from the update object before it is sent to the
api endpoint.
