Update to HSQLDB 2.3.1

0.9.9 fixes a number of bugs in the netdb, streaming, and i2ptunnel, and starts work on a year-long plan to increase the strength of the cryptographic signing algorithms used in the router, and support multiple algorithms and key lengths simultaneously. Automatic update files will now be signed with 4096-bit RSA keys.

0.9.8.1 fixes a problem with updating to 0.9.8 on Windows for some people. New installs and non-Windows platforms are not affected, however all platforms will automatically update even if running 0.9.8.

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 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.

0.9.4 includes a fix for a network capacity bug, introduced in 0.9.2, that was reducing network performance and reliability. It also includes major changes in the in-network update system, and adds the capability to update via in-network torrents.

0.9.3 includes extensive low-level changes to the queueing of messages in the router. We implement the CoDel Active Queue Management (AQM) algorithm. We also unify the queueing and priority mechanisms in the transports to aid diagnosis and reduce network latency. Work continues on fixing UDP transport bugs and making UDP more resistant to attacks. There are more changes to improve the performance of the router and reduce its memory usage. Also, we enable i2psnark's DHT support, introduced last release, by default.
