These builds are for 6.3 and 7.0b100.There are more concise descriptions on the 
respective pages, but  a brief overview


Geometry Tools; surprisingly,  creates and modifies geometry: 
 Create 3D Text, 3D Shapes (from roto curves), Voronoi-shards, and copy 
geometry onto points or with an accumulated transform.
 3D Curves that you can sweep, revolve, or create an axes on.
 Boolean operations, face/edge extrusion, Catmull-Clark subdivision, face 
removal/poking and point merging.
 Test geometry for intersection with an ellipsoid, trapezoid, or cylinder for: 
modifying attributes with values or expressions, and applying Transform, Bend, 
Bulge, Taper, and Twist deformers.


Dynamics; oddly enough, allows rigid and soft body simulations in Nuke.
 Integration with particles to trigger emission when objects collide or 
simulate geometry emitted from a stream.
 Achieve realtime playback with a massive amount of objects (30,000 for 
example).
 Simulate deforming geometry and concave objects.
 Animatable properties and constraints (point, hinge, spring, soft pin, soft to 
rigid).
 Baking of both rigid and soft bodies (invokable in UI and command-line).
 Bake object transforms to Axis nodes.









Thanks, and let me know of any issues.
