Default updating bootloader advice request?

My nex 10 is unlocked with twrp and latest cm11 build installed.
I checked my bootloader version today and noted it was LJ09.
There have apparently been 3 bootloader revisions since this, the latest being MF01 http://www.randomphantasmagoria.com/...s-10/mantaray/
Is it worth updating to the latest bootloader or should I not risk it?
Also, the link above kind of suggests the bootloader would have to be updated in steps, one version at a time. Is that right or can I go straight from LJ09 to MF01?
