0.9.5 includes bug fixes and defenses for some issues and vulnerabilities that are being investigated by researchers at UCSB. We continue to work with them on additional improvements. This is a good opportunity to remind the community that while our network continues to grow rapidly, it is still relatively small. There may be multiple weaknesses or bugs that could compromise your anonymity. Help us grow the network by spreading the word and contributing where you can.

In this upgrade cycle, a random 1% of routers, (plus all routers running a development build) will attempt to update via the experimental in-network bittorrent with i2psnark. If this doesn't work, it should fall back to standard in-network HTTP update.

Files are available on the download page.
