There no real need to update unless after all trouble shooting has been exhausted, to update. Yes there were some issues with some of the FW releases however not everyone saw issues with these version. Hence, set up the router and enjoy it as is out of the box first. FW updates have to deal with some fixes in code however mostly it's to fix a defect possibly or add in a new feature. There were no new features added after v1.15 I think. Have to go back and look. Run the router and see how it does, set it up and if your a gamer, check out the stickies. I promise you, you'll enjoy it. I do.
