2009-01-24: 0.7 Released
The 0.7 release adds stability and flexibility to I2PSnark, which can hopefully be used to distribute I2P updates in future.
The I2P router gets fixes and optimizations to various transport-level and streaming issues, network exploration, NetDB performance and the UDP introducer system. Among other features, the new release offers better connection limiting, higher tolerance to "out of memory" exceptions in helper applications, and an experimental new address system using Base32 hashes of destination keys (".b32.i2p" URLs).
Both the BOB and SAM protocols are improved upon, more old components dropped, Router Console features added and a possible latency measurement attack mitigated. From this release onwards, block lists for misbehaving peers are activated by default.
It seems worthwhile to remind that already since the last release, I2P requires Java 1.5 or higher. If you are uncertain about your Java version, you can verify by opening a terminal window or command prompt, and entering the command "java -version". If you have an older Java installed, please update it first!
