I hate to start off my first post here with a silly question,but i have had my D5100 for about a week now and love it.I have been doing alot of reading and I can`t tell if I need to update my firmware for it.My firmware as of right now reads like this(and its kinda confusing me).

A - 1.01
B - 1.01
L - 1.006

I know that may look like a typo but its not.
Any help would be greatly appreciated.
