0.9.11 continues improving LeaseSet lookup and storage to prevent an attacker from correlating a Destination with a Router. It adds support for the Orchid outproxy plugin which is available at plugins.i2p. There is a reduction in memory usage due to fixes in the transports. We have some I2CP protocol improvements that will provide better lookup facilities and authorization protection for external clients. Of course, there's also the usual collection of bug fixes. All users should update.

This may be the last release that works with Java 5, which is very old and unsupported. If you are using a Java 5 or 6 runtime, we strongly recommend that you upgrade to Java 7.

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.
