As you all have noticed, the unprecedented network growth starting October 5th has dramatically increased network congestion, especially on evenings (UTC) and weekends. The last two releases contained a few changes that we hoped would relieve the pressure, but unfortunately these measures have been only modest successes. The primary issue is to limit the number of direct router to-router connections in the network. This isn't a new problem; we've been working on it for several years, with good results. However, the recent growth pushed us over the edge once again.

Release 0.8.11 includes several more changes to reduce the number of router-to-router connections and increase connection and tunnel build capacity. The goal, of course, is to improve tunnel build success rates and general reliability. As always, there's a few bug fixes and translation updates.

We welcome all our new users. Please be patient as we work to improve network performance. Debugging congestion problems in a distributed anonymous network is a continuing challenge. Please help improve the network by restarting your router once the upgrade is downloaded.
