And beta 3 for the Linux port is ... well, coming. Sometime.
I'm hacking the network-transparent code into it slowly, as I get time, so once I get that done I'll add the generation the minimum was found on, and release it as beta3. I don't know if it'll be able to inherently handle multiple clients at that point, or not. The network transparence does come at a very minor disadvantage -- sending sizeof(dfclientconfig) across the network when you make a change to the configuration, and sending the bench data across the network at the refresh interval.
Jeff -- does the best energy reset now when a new 250-gen sequence is started?
