BQ28Z610: BQ28Z610 0.20 firmware

Part Number: BQ28Z610

Hello, I need to save a Golden Image with the BQ28Z610. I downloaded version 1.3.104 of the Battery Management Studio, but I have read that firmware version 0.20 is also required. My BQ28Z610 devices report version 0.17. Where can I download firmware version 0.20? On the site I find only 0.17.
