Why Can't I Connect? 1.9.0 release notes:

• Added the neighbors tool. This identifies all the named devices within a range of IP addresses. Note: The neighbors tool uses the socket function getnameinfo and, depending on your operating system, ICMP echo requests. These inquiries may be blocked by a firewall and I do NOT try to circumvent these security measures.
• Added the MAC address in the bind trace when the trace detail level is set to high.
