[Bf-gamedev] New Bullet version and Featherstone

[Jacob Merrill]

The new Bullet 2.82 SDK is available for download. It allows for higher
quality physics simulation, suitable for robotics, using the Featherstone
articulated body algorithm. The release also introduces a new Mixed Linear
Complementarity Problem (MLCP) solver interface, with various direct solver
implementations. Read more here.

Our focus is now on integrating all Bullet 2.x features into the upcoming
Bullet 3.x SDK. You can learn more about its progress in our SIGGRAPH
course notes on GPU rigid body simulation at the Multithreading and VFX
website.

So in 1 paragraph they talked about both multithreading and Featherstone,
this may be why I was confused,
