Level 20 and up characters will probably be excited to know that there's a new quest that they can complete now. Lower level characters will have to wait to bask in the glory of the new quest, or something like that.
Enot has been kind enough to illustrate another 4 items and 2 monsters for us, you'll find them in places you might expect them.
Finally, potions are more potent now. More specifically, I've doubled the HP gain they give, so a potion that previously gave 15 HP now gives 30 HP. The rest of the multiplications are left as an exercise to the reader, or you could just look at the item descriptions.
