The Rocket viewer version 2.4.1 for the Meshmoon hosting service was launched earlier this week. One of the highlights of the release is a fix to a Mumble VoIP related bug that has been bugging us for a while now. As a result, you should see marked improvements in sound quality over the previous versions, especially in situations with several people in the conversation. We encourage everyone to try out the enhanced VoIP and let us know how it works. The fixes should also be available in the future realXtend Tundra releases, but for now you will need to go to Meshmoon to try out the new VoIP.
The latest Rocket viewer (Win & OSX) is available here. If you have one of the previous versions, autoupdate will get you up to date next time when you launch the rocket. Full changelog is available here
