Full help output is no longer displayed for usage errors. Apple Mac OS X Tiger, Leopard, and Snow Leopard are now supported. The license was changed from GPL v2 to v3. A DoS warning was added to the manpage and help output. New arp fingerprints were added. gcc compiler security options were enabled. "make check" tests were added. The Perl scripts were modified to work on systems where the perl executable is not in /usr/bin. Various minor bugfixes and improvements were made.

A new --pcapsavefile (-W) option to save the ARP response packets to a pcap save file for later analysis. A new --vlan (-Q) option to create outgoing ARP packets with an 802.1Q VLAN tag.
