Only Asterisk 1.4 needs patching. You do not need to do anything since asterisk 1.8.
However, in order for attendant transfer to work in fop2, you must enable it in asterisk features.conf and you must add tT to the dial options in your dialplan (to allow transfers). Otherwise when you attempt and attendant transfer, you will probably hear dtmf and nothing will happen.
