The update also includes a lot of other upgrades, including the ability to change font sizes, switching between the mage's spellbook and priest spells is easier, and of course some bug fixes. NPCs have been updated as well. Now if they are blinded they will roam around until they happen upon someone to attack. Also, Drizzt Do'Urden finally has his classic scimitars to closer represent his character in the Forgotten Realms book series.
There are plenty more improvements to explore in the game. You can check out Baldur's Gate: Enhanced Edition for $9.99 on the App Store.
