Breath of the Wild was patched to version 1.1.2 last night, and all Nintendo is saying in the related patch notes is that "adjustments have been made to make for a more pleasant gaming experience." That's it. No explanation, no examples.

Although not mentioned in the notes, numerous reports indicate that Nintendo has patched out a particularly useful exploit that allowed players to farm up to 999 arrows from enemies while not taking any damage. Pre-patch, if you positioned Link in a safe spot near a group of Bokoblin archers, they would keep twanging arrows at him indefinitely, but would never actually hit him. You could collect a full stash just by picking them up off the ground. Since last night's patch, the Bokoblins seem to have gotten smart to the trick, and now after Link has collected a dozen or so arrows, he's unable to collect any more.
Perhaps it's best to stock up on arrows before you apply the patch.
