NMAP 4.0 Released
Nmap has undergone many substantial changes since the last major release (3.50 in February 2004) and they recommend that all current users upgrade.
The changelog is huge. My personal favorite is revriten scanning engine, not only is it faster but its also less memory hungry (I have a lot of old machines set up for testing, routing and firewalls).
Also worth mentioning is improved service(and version) detection, and os fingerprinting.
