Howl is a cross platform implementation of the Zeroconf zero configuration networking standard. It includes daemons and a client side SDK for registering, browsing, and resolving network services, and assigning link local IP addresses without a DHCP server. On Windows 2000/XP, it includes a sidebar in Internet Explorer that allows users to browse zeroconf-enabled Web and FTP servers. This release fixes a broken Makefile.am and a compilation error on FreeBSD. Elsewhere, Apple has recently released Technology Preview 3 of Rendezvous for Windows.
