G-Speed es Pro (mini SAS)

Hello. I’m not having problems with my es Pro. However, how can I make sure I have the latest firmware? I downloaded 2 .blf files from the G-Tech site - “rr4322-gtech.blf” and “sas4.10.3.0.blf” I’m not sure if and how to try and utilize these files? My controller is the Atto R680. Thank you in advance for your input.
