There is a new version of the Newton Game Dynamics SDK available for download (Win32, Linux and Mac).

It mostly contains bugfixes and also some nice speed-improvements over the last version. I also updated the headers, which you can download here. The headers didn't change much, but the function NewtonWorldRayCast now takes an additional parameter (prefilter callback), so if you use it please get the new headers and dll and recompile your project.

I also plan on releasing an updated version of NewtonPlayGround very soon, to reflect the improvements of the recent Newton SDK (no date yet, it's finished but still needs some testing, so maybe this or next weekend).
