I'm trying to to retrieve most recent master version from the Hexxeh/rpi-firmware which is used by Ubuntu Mate 16.04.
rpi-update update script exist on this page but I'm unable to fishout how they check if their version is newer than my local one.
What repo file, or what CLI/Bash command cold I use to get the newest available version online?
I could do
sudo JUST_CHECK=1 rpi-update but is there cleaner way?
