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 beinhaltet erweiterte low-level Änderungen der Nachrichtenwarteschlange im Router. Wir haben den CoDel Active Queue Management (AQM) Algorithmus implementiert. Außerdem wurde der Transportwarteschlangen - und Transportprioritätsmechanismus für bessere Diagnose und Netzwerk Latenz vereinheitlicht. Wir arbeiten weiterhin an der Beseitigung des UDP Transportbugs und machen UDP sicherer gegen Attacken. Des weiteren gibt es am Router änderungen zur Leistungssteigerung und Verringerung des Speicherverbrauchs. Ebenfalls wurde die DHT funktionalität von i2psnark, welche mit dem letzten Release eingeführt wurde, standardmäßig aktiviert.

0.9.2 beinhaltet umfangreiche, tiefgehende Änderungen, um die Performanz und Effizienz des Routers zu verbessern. Wir haben unsere UPnP-Bibliothek aktualisiert, um hoffentlich UPnP für mehr Leute nutzbar zu machen. I2PSnark unterstützt jetzt DHT, aber es ist standardmäßig noch nicht aktiviert, da wir in der Entwicklungsphase zur 0.9.3 noch weitere Tests planen.

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.

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.

The 0.8.12 release fixes several message corruption bugs, some present since 2005. It also contains a redesign of the router's congestion control, and continued optimization of CPU and memory usage. We are hopeful that these changes will improve network performance.

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. As always, there's a few bug fixes and translation updates.
