There is a lot of themes changes that we are going to turn on for 3.0 I guess. These are like lightweight skins.

The real changes are invisible and mostly on the Ultrapeer (i.e. Dynamic Querying, Ultrapeer Query Routing on the last hop, Higher outdegree/lower TTL). These are what we are really trying to beta right now and fix (no doubt) lots of problems with. This is our big shot at changing the way Gnutella works by making it much more efficient (100x) and less resource consuming for messaging (selective broadcasts rather than pure broadcasts). Until these changes fully take hold, we need to work to tone down the messaging rate of the existing network. Thus, we need to make some of these changes (outdegree vs TTL) in stages.
