Seamless integration with Maya shapes, cameras, lights and shaders.
Image Based Lighting support, including a state of the art physical sky.
Interactive rendering (IPR) allows parameter changes to be rapidly previewed without interrupting your work.
Support for volume rendering with Maya Fluids.
Support for Maya Hair and nHair.
Particles and nParticles support, including particle instancer.
Defer the creation of geometry at render time with the Stand-in placeholder nodes.
Productivity boost: override sets, holdout mattes, shadow catcher, passes, UDIM style textures, and arbitrary primvar data.
Extensible through plug-ins (Golaem, FumeFX for Maya, Yeti, Shave & Haircut).
XGen integration.
Texturable geometric lights.
Deep EXR.
Rendering of curves.

Changes 3.0.1 (Release Date: June 4, 2018)

Arnold Viewport rendering (Maya 2018 only):
It is now possible to render inside the Maya viewport, by switching the viewport "Renderer" to Arnold. Some of the Arnold RenderView options are exposed, like Region Rendering, Debug Shading, Isolate Selected, AOVs, etc... This feature is only available with Maya 2018

AOVs:
- Added token in output filename, so that Light Group AOVs tokens can be inserted in custom ways.
- Option Output Denoising AOVs now automatically dumps the optional AOVs for noice (diffuse_albedo, Z, N). This requires EXR output files.

Arnold Denoiser UI:
The new menu "Arnold -> Utilities -> Arnold Denoiser UI (noice)" allows to denoise previously rendered images. This requires that the input images were rendered in exr with merged AOVs enabled.

Bugfixes:

Improved stability with incompatible OptiX versions
Fixed crashes when editing nHair nodes during IPR sessions.
Fixed crash happening with snapshots resolution changes.
Fixed errors in Render To Texture when '|' characters exist in the Maya node name

Incompatible changes:

MaterialX Operator's parameter mtlx was renamed filename
Light Group AOVs now add the group suffix before the frame number
