The alpha Tor Browser Bundles have all been updated to the latest Tor 0.2.3.20-rc release candidate as well as being updated with some bugfixes. We're getting closer and closer to releasing the 0.2.3.x series as stable, so please give these bundles a lot of testing and help us shake out all of the remaining bugs! The regular bundles have also been updated.
