pybox2d isn't dead just yet.
A few days ago, I started porting the bleeding-edge version of the library.
Some changes include the addition of b2Fixture, contact listener changes, a new way to create edge chains, and significant algorithm changes. More information on these C++-specific changes can be found on the forums and the Box2D SVN changelog.
As it is a departure from the previous builds, it will stay as a branch on here at least until it's significantly improved over the trunk. I'm not entirely happy about the significant API changes that are occurring, but I'm just bringing to Python what Erin Catto and others are making available to the C++-world. I guess what I'm trying to say is, well, don't shoot the messenger.
