Using hassbian script to upgrade from 3.7.3rc1

Recently I did a fresh install of hassbian. I downloaded the latest image [v1.6/ I did not noticed that this version is based on debian buster which is not released yet.

My question is if I can use the hassbian script to update from python 3.5 to the latest stable version (as mentioned in the release notes of HA 0.94) because I am already on python 3.7.3rc1.

I prefer using a stable version which 3.7.3rc1 is not (i think)…
