Welcome!

Here is the stable 0.9.1 release and the mtn builds based on it

Release notes are published under the official www.i2p2.i2p page.

Remember: from the release 0.7 on you need Java 1.5 to run I2P, SUNs Java 1.6 IS REALLY preferred!
No more headless installer files - thanks to a update of the installer package the i2pinstall.exe can be run headless!
If you have installed I2P from the PPA, have a look on I2P debian installer page and look for updates in the PPA.

Use: java -jar i2pinstall-0.9.1.exe -console.
