Upgrading firmware for 6D from 1.1.3

[LovePhotography]

I've got a one year old 6D with factory installed 1.1.3 firmware.
Should I update to the latest?
Is there good reason? If there is something important that I am missing out on, then I want to, but don't want to risk one of these update horror stories if not much of anything happens.
About the only thing I wish for is faster AF. But, I dunno. I haven't really done much "fancy stuff". I mostly take stills in natural light.
Thanks for the advice.

There is a section on CR describing the changes.

I'd say its worthwhile. The update came out 2-1/2 months ago and very few had issues after installing it.
