The Drive and Libredrive report FW 1.01

Should I update to a later flash? What would I gain? Are there release notes?

ps I reflashed with /Applications/MakeMKV.app/Contents/MacOS/makemkvcon f -d /IOBDServices/E8BA6DA0 -f /tmp/sdf.bin rawflash enc -i /tmp/HL-DT-ST-BD-RE_BU40N-1.03-NM00000-211810241934.bin - but the FW stayed at 1.01.

Remove enc

That worked. Thank you!

Cheers,
