The first release of dyn4j is out!
It’s taken me a while but I think its release ready. You can download the release on the Google Code project site here. All the Javadocs, features, and getting started pages have been updated accordingly. In addition to this the forums have been opened.
There is still a lot to accomplish as you can see by the Features page. Two items on there, Raycasts and CCD may require some API changes and will be large changes none-the-less.
