So if you have any of the hacks running on your 3DS system DO NOT UPDATE!! Here is what smea @smealum had to say on Twitter just this afternoon.

ninjhax users can just go ahead and update most likely. ironhax/oot3dhax should probably wait for updated payloads.
getting confirmation that themehax was patched. so yeah, don’t update yo.
