I believe the title is straightforward, I am yet to get a clear answer on this. I gathered this from the website:
Fusion solves the problem of fragmentation in AR-enabling technologies, including cameras, sensors, chipsets, and software frameworks such as ARKit and ARCore. It senses the capabilities of the underlying device and fuses them with Vuforia features, allowing developers to rely on a single Vuforia API for an optimal AR experience. Vuforia Fusion brings advanced Vuforia features to ARKit-enabled devices, in addition to over 100 Android and iOS device models.
But searching "arcore" in the release notes returns absolutely no result (as opposed to arkit)... hence my question.
(I am using unity but the question still holds for the android sdk I suppose)
