Today we saw one of the largest recent API changes come to pass, "mesh" is now something that can be applied to a Body, not a type of Body itself.
soy.bodies.Pyramid is gone, there is now a pyramid.py in tests/ which provides it for the test scripts. I also copied over the blocks.py file from Blockdropper (one of my old Soya games) and updated it's API for our engine. That is the screenshot I included here.
There are a few tickets remaining for Beta-1, but barring some last minute critical bug discovery we should be set in the next 16 hours.
