This release, I2P 2.4.0, continues our effort to improve the security and stability of the I2P network. It contains significant improvements to the Network Database, an essential structure within the I2P network used for disovering your peers. The congestion handling changes will improve network stability by giving routers the ability to relieve congested peers by avoiding them. This will help the network limit the effect of tunnel spam. It will also help the network heal during and after DDOS attacks. The NetDb changes also help secure individual routers and the applications that use them. Routers can now defend against attackers by separating the NetDB into multiple "Sub-DB's" which we use to prevent information leaks between applications and the router. This also improves the information available to Java routers about their NetDB activity and simplifies our support for multihoming applications. Also included are a number of bug-fixes and enhancements across the I2PSnark and SusiMail applications. As usual, we recommend that you update to this release. The best way to maintain security and help the network is to run the latest release.
