The update brings support for the 3ds Max Physical material, the Arnold Standard Surface shader, and the Autodesk Interactive shader. What is more, you can now set up support for other third-party materials.
Also, there's the option to disable viewport picking for parts of a scene, so it's now easier to select the correct scene objects for editing.
There's a number of new features for 2D artists and the most important is an experimental sprite swapping system generating character variants with different looks.
There's more, of course, for developers with all kinds of projects. You can find a thorough breakdown here.
