Kef LS50 Wireless Firmware update

I got some Kef LS50 Wireless speakers a few days ago and am wondering if I need to do any firmware updates to the speaker or if on initial setup, this was done...

Forgive my ignorance on the subject.  Also, it seems like a pain / gamble to update anything that is already working properly (apple...).  If its not broken, well, I can break it in order to spend the next week trying to get back to square one :-p
Usually updating the firmware includes updated features so doing an update in not necessarily a bad thing with the KEF.  I have the same speakers and always update when the new firmware does out.
