Bootloader V4 update necessary/recommended?

Hi,
I saw that there is a new bootloader V4 from 03.02.2014 (PX4FMUV2) avaliable.
For whom would this update be recommended?
Is the update via SDCard and NSH shell over APM terminal a valid way to do the update?

pixhawk.org/dev/bootloader_update

OR: "Do NOT update the bootloader unless being asked to do explicitely. "

The bootloader was last changed about 2 months ago

github.com/diydrones/ardupilot/ … bootloader

All Pixhawks shipped with that bootloader and the bootloader is included in the ROMFS of each build of the APM flight code so instead of loading of the sd card you can load directly from the ROMFS

bl_update /etc/bootloader/fmu_bl.bin

All this to say:
There is no requirement to update

OR: "Do NOT update the bootloader unless being asked to do explicitely. "

Thanks Craig,

I saw some changes on github in the last weeks, and on pixhawk.org only the V3 was documented. The V4 is dated in february 2014. So I thougt it could be necessary.
