I've been testing R80.20 very intensively in the lab over the last few days. Here I have discovered some interesting new commands on CLI. What did you discover that didn't exist before?
# cphaprob stat > with more clusterxl informations
# fwaccel ranges > show's anti spoofing ranges
# fw ctl multik utilize > shows the CoreXL queue utilization for each CoreXL FW instance
# fw ctl multik print_heavy_conn > shows the table with heavy connections
