Added metadata support: All the information that Aton has on its framebuffers is now stored in the node as a metadata.

New Operator Aton: operator_aton is designed to replace all output drivers with aton driver at render time. In DCC apps like Houdini or Katana where the driver selection is not exposed in the UI, this can come handy to use Aton without extra scripts.

Distributive rendering on the farm: The frame can be split into smaller tiles and distributed on the local render farm via region arguments. It's fully farm manager agnostic, meaning you have to sub-class and implement supplied virtual methods in the python script in order to get it to work for the given farm requirements. At this moment this feature is only available for Houdini, but similar scripts should work fine for the other DCC apps too.

Render Region: Region handles have been added in the node, which accelerates the workflow. It's still possible to use a crop nodes too.

Render Layers: Render Layer names will show up as a prefix for snapshot's name on the stack. There is an arbitrary output entry in the Arnold driver which can be set by a script.

Auto Snapshots: Each IPR session is now automatically being kept in memory with options to take, rename, reorder and remove the snapshots. Use write to disk options to permanently store them, as it was done before with capturing.

HtoA implementation is based on the research article from Ryan Heniser, but the workflow is similar to Maya and Cinema 4D. See how to install at the bottom of this page.

Dockable UI in Maya: By default Aton UI in Maya is now docked at right corner.

Extra Host improvements: It's now possible to stream the rendering to Extra Host, without necessarily having a local Nuke session opened.

Live Camera support: By Enabling Live Camera checkbox, Aton will create an interactive camera node in Nuke, which will update during IPR and frame change.

Sequence Rendering: New rendering mode has been added from Dan Bradham, allowing to batch render a multiple frames at one go.

Shader override support: Quickly override all or selected object's shaders to Checker, Grey, Mirror which are useful for look development and lighting, as well as to Normal, Occlusion and UV, for debugging.

Full IPR Support within Aton UI in Maya: No longer need to refresh every time you switch the camera or set an overrides.

Multiple frames support: By default it is enabled, meaning Aton is now taking into account the frame attribute supplied by MtoA and syncing Nuke's timeline accordingly, so you can have a sequence of rendered different frames cached in a single Aton node.

Enable AOVs toggle: If you Disable AOVs, Aton will start to ignore and not cache them for you. This can come useful if you want to render multiple frames, at the same time keeping the memory usage low.

Multiple nodes support: It's now possible to create a multiple Aton nodes either in the same Nuke script or in the separate instance, as well as run renders from a different instances of Maya simultaneously. In order to get this to work, make sure that your Aton node's Port number is matching with the one which has been added to the Aton for Maya GUI.

Frame Stamp enhancements: Arnold version and Frame numbers have been added to the Status bar, and the Time is now resetting after every IPR iteration.

Capture All Frames: It's possible to capture all the rendered frames at once, as a sequence. In this mode the frame number will be inserted in the file names instead of the current date.
