Hello I2P! This is the first release signed by me (str4d), after 49 releases signed by zzz. This is an important test of our redundancy for all things, including people.

Housekeeping

My signing key has been in router updates for over two years (since 0.9.9), so if you are on a recent version of I2P this update should be just as easy as every other update. However, if you are running an older version than 0.9.9, you will first need to manually update to a recent version. Update files for recent versions can be downloaded here, and instructions on how to manually update are provided here. Once you have manually updated, your router will then find and download the 0.9.23 update as usual.

If you installed I2P via a package manager, you are not affected by the change, and can update as usual.

Update details

The migration of RouterInfos to new, stronger Ed25519 signatures is going well, with at least half of the network already estimated to have rekeyed. This release accelerates the rekeying process. To reduce network churn, your router will have a small probability of converting to Ed25519 at each restart. When it does rekey, expect to see lower bandwidth usage for a couple of days as it reintegrates into the network with its new identity.

Note that this will be the last release to support Java 6. Please update to Java 7 or 8 as soon as possible. We are already working to make I2P compatible with the upcoming Java 9, and some of that work is in this release.

We have also made some minor improvements in I2PSnark, and added a new page in the routerconsole for viewing older news items.

As usual, we recommend that you update to this release. The best way to maintain security and help the network is to run the latest release.
