Shader Graph smoothness changed? ( Unity 2020.3.1 )

Hi,
I'm not sure if this can be considered a bug or something else, but the smoothness value using Shader Graph is working different on Unity 2020.3.1 ( ShaderGraph V10.3.2 ) compared with the version 2019.4.x ( ShaderGraph V7.5.3 ).

I made some tests with my shader to try to get my old look, but I was unable to reach the same level of specular reflection. Looks like the smoothness value is working in a different way and is now internally clamped from 0 to 1.

Here is a screenshot with the same smoothness value of 0.96f with both Unity versions.
