0.9.7 includes significant bug fixes and improvements.

For the first time, class 'N' routers (those with a minimumum of 128 KBytes/sec of shared bandwidth) will automatically become floodfill (previously it was only 'O' routers with 256 KBps). This will increase the floodfill population for additional resistance to certain attacks (see below). Floodfill routers don't consume much additional bandwidth, but they do tend to use additional memory and concurrent connections. If you do not wish your router to become floodfill, set the advanced configuration router.floodfillParticipant=false .

As we think the last release fixed the experimental update-via-torrent bugs, 3% of routers should update over in-network bittorrent this cycle.

Plugin update checks, possibly broken for several releases, are fixed. Your plugins should once again auto-update after updating the router.

We fixed a major streaming timer bug that contributed to frequent IRC disconnects.

This release contains additional mitigations for the "practical attacks" paper. However, we have a lot more work to do to resist Sybil attacks on the floodfills, and resist traffic analysis at the gateways and endpoints of exploratory tunnels. It's a good reminder for everybody that our network is still relatively small and vulnerable. We don't currently recommend any uses that would put anybody in serious jeopardy. We'll keep working to improve it... please keep working to spread the word. A bigger network is a better network.
