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.

In the 0.9 release we migrate to Jetty 6 for the console and eepsite web server, and introduce a simplified router console home page. This release is network-compatible with prior releases, however see below for important information on compatibility with existing eepsites, plugins, and webapps. Upgrading is recommended.
