I believe you’ll need a higher nuke addon version to match with latest ayon core. Same likely for blender, maya, etc.
I think for Nuke you need 0.2 or higher. @iLLiCiT shouldn’t there be a warning or even compatibility error for this?
The versions warning you can ignore - that’s a recent feature implemented where addons report versions but not all addons reported their versions yet; but should be resolved now with all latest addon versions if you update all of them.
