There never was a "new IP address" function in Tor.

NEWNYM    -- Switch to clean circuits, so new application requests
             don't share any circuits with old ones.  Also clears
             the client-side DNS cache.  (Tor MAY rate-limit its
             response to this signal.)

Two things are important here:

 * existing/open application requests still use old circuits
 * new circuits don't exclude previously used relays; after "New
Identity", you might end up exiting from the same exit relay, for example
