Unvanquished Open-Source Game Still Coming Along, More Assets Licensed CC-By-SA 3.0
Unvanquished developers have put out their first blog post in several months. In there they talk mostly about getting more of the in-game assets licensed under the Creative Common Attribution Share Alike (CC-By-SA 3.0) license. They almost have all of their models unified under this nice open-source license for assets except for being unable to reach someone who had been one of their more prolific contributors.
More details on their model licensing work and tooling can be found at Unvanquished.net.
