0.8.11 Release
==============
.. meta::
:date: 2011-11-08
:category: release
:excerpt: 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.

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.

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.

- Improve peer profile capacity metric to include factors for connection, reachability, country, and router hash, to reduce connection churn
- Adjust connection limits and timeouts to increase capacity
- Adjust router info and peer profile expirations to reduce memory usage
- Rebuild existing tunnels some of the time to reduce connection churn and improve build success
- Build Executor / Handler thread separation to increase build handling capacity for high-speed routers
