0.9.8 includes the long-awaited support for IPv6. It's enabled by default, but of course you need a public IPv6 address to use it. Configuration is on the 'network' configuration tab in your console. We also have anonymity improvements including padding of SSU packets and longer router private keys.

This unscheduled release disables the RouterInfo verification messages that were used in the attack published in the UCSB paper, which should make correlating a LeaseSet and a Router much more difficult. We have also included a limited number of other fixes listed below. Our 0.9.8 release, which will include IPv6 support, is still on-schedule for late September.

0.9.7 includes significant bug fixes and improvements.

0.9.6 includes bug fixes and an update from Jetty 6.1.26 (2010-11-10) to Jetty 7.6.10 (2013-03-12). See below for important information on the Jetty update. The Jetty 7 series is actively maintained and we plan to stay current with it in future I2P releases.

0.9.5包括对UCSB的研究人员正在调查的一些问题和漏洞的错误修复和防御措施。我们将继续与他们合作进行额外的改进。这是一个提醒社区的好机会，虽然我们的网络继续快速增长，但它仍然相对较小。可能存在多个弱点或错误，可能会损害你的匿名性。通过传播信息和贡献您的力量，帮助我们发展网络。

0.9.4包括对0.9.2中引入的一个网络容量错误的修复，该错误会降低网络性能和可靠性。它还包括网络内更新系统的重大变化，并增加了通过网络内种子下载更新的能力。

0.9.3包括对路由器中的消息排队的广泛的低层次的改变。 我们实现了CoDel主动队列管理（AQM）算法。 我们还统一了运输工具中的队列和优先级机制，以帮助诊断和减少网络延迟。 修复UDP传输错误的工作仍在继续，并使UDP对攻击的抵抗力增强。 还有更多的变化，以提高路由器的性能，减少其内存使用。 另外，我们默认启用了i2psnark的DHT支持，这是上次更新时引入的。

0.9.2包括大量的底层修改，以提高路由器的性能和效率。我们更新了我们的UPnP库，希望能让UPnP为更多人所用。I2PSnark现在支持DHT，但还没有默认启用，因为我们计划在即将到来的0.9.3开发周期中做更多测试。

0.9.1 includes a large number of bug fixes in i2psnark, some streaming lib improvements, home page changes, new themes, and translation updates.

The 0.9 release concludes over a year and a half of work on the 0.8.x series, in which we greatly improved the performance and security of the router, and the scalability of the network.
