The latest update introduces two new GI engines, support for tonemapping, random walk subsurface scattering, and more.
OpenVDB toolset has also been improved: Disney’s Partio particles library has been integrated and there are improvements to Layout, Modeler, and the OpenGL viewport.
First, there's a new global illumination system including separate render engines for primary and secondary light bounces. You can now use new Brute Force or Irradiance Cache engines for either primary or secondary bounces. There's also support for tonemapping, and more.
