1.     Solver bug fix #1– Large bending stiffness caused the solver to blow up.  This bug is fixed in 4.0-5.

2.     Solver bug fix #2 - Cloth meshes with duplicate faces with identical vertices produced unexpected results with the 4.0-3 solver.  This behavior is fixed in 4.0-4.

3.     Plug-ins for Maya 2008, 2009, 2010, 2011 are removed from the deployment package.
