The Avahi team would like to announce the immediate availability of 
Avahi 0.1 "Guten Tag".

Avahi is a fully LGPL framework for Multicast DNS Service Discovery.
It allows programs to publish and discover services and hosts 
running on a local network with no specific configuration.  For 
example you can plug into a network and instantly find printers to 
print to, files to look at and people to talk to.

Avahi is designed to be compatible with the mDNS/DNS-SD specification 
and boasts the following features

 * Fully open source and freely available under the LGPL
 * Full IPv4 and IPv6 support
 * An embeddable mDNS stack
 * Dynamic adjustment to network reconfiguration
 * Daemon with DBUS API for desktop applications
 * C library to interface with the DBUS API
 * Compatible with other mDNS/DNS-SD implementations such as
   Howl and Apple Bonjour (previously Rendezvous)
 * Ability to correctly "reflect" mDNS between two or more LAN segments
 * Ability to configure DNS servers based on mDNS/DNS-SD published
   information, a feature that is very usefull on IPv6
   which has no other mechanism for this.
 * Combined with nss-mdns, allows hostname lookup such as 
   'laptop.local' without the configuration of a DNS server.
 * Easy integration into GLIB, GTK other mainloop applications.
 * Documentation and examples of both developer APIs and utilities.

mDNS/DNS-SD is part of a larger set of specifications for easy 
configuration of networking known as "ZeroConf" 
(http://www.zeroconf.org/), with the aim of allowing you to plug into 
a network and instantly be able to interact with it's services.

Avahi was designed to be a fully free implementation, and is 
available under the LGPL.  Many other implementations of the mDNS/DNS-SD 
specification were previously non-free, restricting their use in many 
platforms such as the GNOME desktop and many distributions.

While Avahi is a 0.1 release, we feel it is feature complete and 
available for immediate use, developers can make use of the Avahi 
client library to provide above mentioned functionality in their
