Root Bootloaders difference

[guidogoni]

Hi!
I've been an android user for some time now, but with recent updates and all that, I just don't understand what bootloader versions stand for.
I have an argentine milestone with canada 2.1, everything works great, but I still have the default bootloader that came with my phone, what changes if I update this to the "newest" 90.78 ?
Are there any efficiency changes? New options?
Can't find anything related to this searching on the net.
Hope anyone has an idea or can find bootloaders difference.
Thanks!

I wouldn't bother unless you are having problems.

The newer versions are most likely to increase the lockdown of the bootloader itself.
