Anenga writes "A Windows (and somewhat WINE compatible) Gnutella client, Shareaza, has released a public preview of its next version which includes a re-designed Gnutella protocol they call "Gnutella2". Gnutella2 (or "G2") dumps the Gnutella broadcast model and uses a new global searching method with UDP connections. It also features compression to limit hub-to-hub (G2 Ultrapeers) bandwidth, Tiger Tree Hashing etc. Shareaza has released a small description of the revised protocol here, but plans to release a full spec to the GDF after the release of v1.7 Final. Gnutella2, which is really a revised Gnutella protocol, will also be free and open for anyone to use in their clients. Shareaza and G2 may give Gnutella - an open and free P2P protocol which has been struggling to keep up with the times against Kazaa, eDonkey and other P2P spin-offs - the stability and power it needs to attract the closed and commercial FastTrack Network users when or if the network folds."
