I2P is an anonymous network exposing a simple layer that applications can use to anonymously and securely send messages to each other. The network itself is strictly message based (ala IP), but there is a library available to allow reliable streaming communication on top of it (ala TCP). All communication is end to end encrypted (in total there are four layers of encryption used when sending a message), and even the end points (”destinations”) are cryptographic identifiers (essentially a pair of public keys).
Latest Changes:

• Use a minimum uptime of 2 hours, not 4
• Cut down the proactive rejections due to queue size – if we are at the point of having decrypted the request off the queue, might as well let it through, rather than waste that decryption
• Bug fix to the I2PTunnel IRC filter to support multiple concurrent outstanding pings/pongs
• Further reduction in proactive rejections
• Don’t let the pending tunnel request queue grow beyond reason (letting things sit for up to 30s when they fail after 10s seems a bit… off)
• Be more conservative in the proactive rejections
• Trim out sending a blank line before USER in susimail. Seemed to break in rare cases
• Small tweak to I2PTunnel CSS, so it looks better with desktops that use Bitstream Vera fonts @ 96 dpi
