New in I2P 0.8.13 (Feb 28, 2012)

  • The 0.8.13 release contains several bug fixes and a couple of new features. We are pleased that the last release significantly improved performance, and the network is running well despite continued rapid growth. Upgrading is recommended.
  • This is likely to be the last release before 0.9, in which we will migrate to Jetty 6, and introduce a simplified router console home page. Monitor the news section of your the router console in the coming weeks for more information on the next release.
  • Starting with this release, the router will check for and install plugin updates shortly upon restarting after a router update. To prevent this, add the advanced configuration plugins.autoUpdate=false before restarting. There is also a new update-all button on the client configuration page.
  • Routers in certain countries will now automatically enable hidden mode for increased protection. However, hidden mode may have lower performance or reliability, and is still a work in progress. To disable hidden mode before restarting, add the advanced configuration router.isHidden=false. To disable hidden mode later, select use all auto-detect methods under IP Configuration on the network configuration page. For the list of countries see the thread on zzz.i2p. The only country on the list that has more than one or two I2P users is China.
  • Major changes:
  • Check for and download plugin updates upon restarting after a router update.
  • Routers in certain countries will now automatically enable hidden mode for increased protection.
  • New Tunnel Wizard for creating tunnels

New in I2P 0.8.12 (Jan 6, 2012)

  • This release contains Several big changes that should help network reliability and performance.
  • The first two changes are fixes for major UDP packet transmission bugs, described below. The third change is fixes to the decompressor. Fixing these should eliminate a big source of message delivery failures.
  • Also, the release contains a rewrite of the router's participating traffic congestion control. It should now more accurately measure current participating bandwidth, handle bursts better, drop messages less, and drop the right messages if dropping is required.
  • Also, the release reduces the amount of processing that routers do for messages they pass down the tunnel. These messages do not need to be completely parsed and validated since the gateway is simply passing them through. This will help performance of all routers but the improvement will probably not be noticeable except on high-traffic routers.
  • We're optimistic that these changes will help, and of course eliminating sources of message corruption is sure to help. However the extend of the improvement won't be apparent until the majority of the network upgrades.
  • The release also contains some updates to the router console light theme. You may need to do a shift-reload or control-reload in your browser to force a reload of the CSS.
  • Major changes:
  • Instead of fully parsing and validating messages received at the inbound gateway, simply pass them down the tunnel
  • Don't verify I2NP checksums in most cases, as message corruption is caught at other layers
  • Don't recalculate I2NP checksums on messages passed through unchanged
  • Several NTCP pumper optimizations, to hopefully fix NTCP pumper high CPU usage on fast routers
  • Rewrite participating tunnel congestion control, to drop less, more accurately measure traffic, and handle bursts better
  • Wrapper Update:
  • New installs include wrapper version 3.5.13 which fixes a heap corruption with very long log lines. See http://wrapper.tanukisoftware.com/doc/english/r... for additional information. I2P PPA package users should have gotten this update in the last week of December. If you do not use our PPA package and would like to update your wrapper manually, follow the instructions at http://www.i2p2.de/manualwrapper .
  • Bug Fixes:
  • Fix major SSU MTU bug introduced in 0.8.9.The router sometimes sent UDP packets that exceeded the maximum size that routers would accept on the receive side. This resulted in a lot of dropped packets, tunnel build problems, and connection problems. One thing that contributed to us missing the problem was that 0.8.9 was released in the middle of the huge network expansion in early October, when network performance was already deteriorating rapidly.
  • Fix major SSU fragmentation bug present since 2005. UDP corrupted transmit messages when the message size was an exact multiple of the fragmentation size.
  • Fix major decompression bugs present since 2005 that caused message corruption and data loss at multiple protocol layers.
  • Snark doesn't always delete directories
  • Fix all character case conversion (Turkish four i problem)
  • Whitelist more IRC commands
  • Remove expired reseed cert
  • Other:
  • Speed up the inefficient GeoIP lookup
  • Optimize several heavily-used utility functions
  • Don't drop the transport connection when receiving an invalid message, it isn't necessary and could be an attack vector
  • Console light theme update
  • Move the complex network configuration stuff to a new console page
  • Add a link to hide the news in the console
  • Allow numerous additional IRC commands through the IRC filter
  • Several other cleanups, optimizations, and object caches added
  • New Estonian translation (thanks ajutine)
  • Spanish, Swedish, Ukrainian translation updates

New in I2P 0.8.11 (Nov 8, 2011)

  • As you all have noticed, the unprecedented network growth starting October 5th has dramatically increased network congestion, especially on evenings (UTC) and weekends. The last two releases contained a few changes that we hoped would relieve the pressure, but unfortunately these measures have been only modest successes. The primary issue is to limit the number of direct router-to-router connections in the network. This isn't a new problem; we've been working on it for several years, with some success. However, the recent growth pushed us over the edge once again.
  • Release 0.8.11 includes several more changes to reduce the number of router-to-router connections and increase connection and tunnel build capacity. The goal, of course, is to improve tunnel build success rates and general reliability. Of course, there's also a few bug fixes and translation updates.
  • We welcome all our new users. Please be patient as we work to improve network performance. Debugging congestion problems in a distributed anonymous network is a continuing challenge. Please help us to diagnose and improve the network by restarting your router once the upgrade is downloaded.

New in I2P 0.8.10 (Oct 20, 2011)

New in I2P 0.8.9 (Oct 12, 2011)

  • The 0.8.9 release has several performance improvements, and many changes to handle the continued rapid growth of the network. It uses a new iterative method for Kademlia network database lookups that should be more reliable and efficient. There are also several improvements to our SSU (UDP) transport protocol that should help reliability and efficiency. We have made several changes to improve tunnel build success rates. And, of course, there are lots of bug fixes and translation updates.
  • The network has grown quite rapidly in recent weeks, and that's great news, but it has caused some instability. We welcome all our new users and we ask you to be patient as we make improvements to the software.

New in I2P 0.8.8 (Aug 29, 2011)

  • I2P release 0.8.8 enables the new hosts.txt database to speed hostname lookups and store additional information on hostname entries. It also includes improvements to speed a router's integration on startup. There is new code to detect and react to large clock shifts that should help a router recover after suspend/resume of the computer.
  • There are new translations for Danish and Ukranian and lots of updates in other languages. Also included are, of course, a large collection of bug fixes, performance improvements, and updates to deal with the continued rapid expansion of the network.

New in I2P 0.8.7 (Jul 1, 2011)

  • I2P release 0.8.7 contains several upgrades to long-neglected components, including the Naming Services, graphing, the native CPU ID and BigInteger libraries, crypto implementations, and the wrapper. For more information, see the release notes and change log associated with the milestone.

New in I2P 0.8.6 (May 20, 2011)

  • The 0.8.6 release contains more peer selection defenses to resist powerful attackers, and tweaks to adjust to the recent rapid growth in the network. Upgrading is recommended.
