+### Migration Notice
+The API changed slightly with N8AO 1.7 - the only change you should have to make is adjusting your `distanceFalloff` parameter - choosing 1.0 is a safe value. For the exact same results you had before, you can do `distanceFalloff = 5.0 * oldDistanceFalloff / radius`.
+
 `intensity: number` - A purely artistic control for the intensity of the AO - runs the ao through the function `pow(ao, intensity)`, which has the effect of darkening areas with more ambient occlusion. Useful to make the effect more pronounced. An intensity of 2 generally produces soft ambient occlusion that isn't too noticeable, whereas one of 5 produces heavily prominent ambient occlusion. 
 
 `color: THREE.Color` - The color of the ambient occlusion. By default, it is black, but it can be changed to any color to offer a crude approximation of global illumination. Recommended in scenes where bounced light has a uniform "color", for instance a scene that is predominantly lit by a blue sky. The color is expected to be in the sRGB color space, and is automatically converted to linear space for you. Keep the color pretty dark for sensible results.
