This powerful feature can be accessed via the AOV groups, outputs and layers elements.
Those are now managed as 3dsMax Texture maps, to provide a more flexible workflow, and take advantage of the Slate editor graph.
The new AOV Scene setting dialog has a single texmap, that is the main AOV Group where multiple AOV output can reside.
In previous versions, all AOV outputs and layers were displayed in a single dialog, that could become difficult to navigate.
Note that the old AOV system is still available for now, via the 'Use Legacy AOV outputs' option.
Here is a simple introduction to the new AOV system usage:

-Load the sample scene 'aov_hue_Begin.max'
-Open the AOV Scene settings dialog
(from Octane menu, 'Open Scene AOV settings' options, or from Octane viewport, multi pass menu, 'Open AOV Settings', or from the Render Setup dialog, in Kernel / Render Settings : 'AOV Settings' button)
-Make sure 'Use Legacy AOV outputs' is disabled in 'Output AOVs [legacy] pannel.
-In Output AOVs Group pannel:
Click the AOV Group texmap button ( indicating 'No map' by default), to create a 'Output AOV group' map
(in -Maps -Octane - Output AOVs)
-Drag this 'Output AOV group' to the Material editor (as Instance)
-Let's rename it from, in this case 'Map #0' to 'main_aov_group'
You should have a Texmap like this (with only Output 1 with no map) :
-Assign the Output1 by creating a Output AOV map
-Let's rename it from Map #1 to beauty_plus_hue
It should have empty 2 layers, like this:
This will be refered to as 'AOV 1 (beauty_plus_hue)' in the passes list, that you can select in the Octane viewport, and in the 'AOV Output' Render Element.
-For Layer 1, create a 'Render AOV' map (in the 'Blend' category : Maps - Octane - Output AOVs - Blend)
Let's rename it from Map #1 to 'beauty_layer'
It is set by default to the Beauty pass, so that's all we need for now.
-Go back to 'beauty_plus_hue'
-For Layer 2, create a 'Adjust hue' map (in the 'Effects-color' category : Maps - Octane - Output AOVs - Effects-color)
-Rename it from Map #2 to 'hue_layer'
-Set the 'Hue shift' value to 40
Open Octane viewport, and select the 'AOV 1 (beauty_plus_hue)' pass.
You can adjust the Hue shift value, or disable and enable the layer 2 to see the effects.
Note that the Hue shift value unit is in degree, so values are expected to be in the range [-180, +180]. (360 will be the same as 0, etc..)
The output can be viewed in the Slate editor:
You can see the final sample scene: aov_hue_End.max
