0.9.20 contains many important bug fixes, and several changes to increase floodfill capacity in the network.

Routers configured for 32-64 KB of shared bandwidth may now become floodfill, and routers configured for 512 KB or more of shared bandwidth will have higher connection limits. These changes may cause your router to use more resources. If the router becomes too busy, the best way to reduce usage is to lower the bandwidth settings in your console. If that doesn't help, you may now disable automatic floodfill on the advanced configuration page in the console.

We're hopeful that these changes will increase network capacity and performance, and reduce the congestion that's been affecting the network the last three months.

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.

Finally, we're excited to announce our first-ever I2P meetup, in Toronto August 15-16. There will be lots of presentations and tutorials. All are welcome. For more information, see the announcement.
