apostle5406 writes to mention that the "Freenet" project (a global peer-to-peer publishing network) has unveiled their first release candidate. "Freenet 0.7 is a ground-up rewrite of Freenet. The key user-facing feature in Freenet 0.7 is the ability to operate Freenet in a "darknet" mode, where your Freenet node will only talk to other Freenet users that you trust. This makes it much more difficult for an adversary to discover that you are using Freenet, let alone what you are doing with it. 0.7 also includes significant improvements to both security and performance."
