Heroes of the Storm update brings Diablo's wizard and a monkey you can catch for gold - CNET

The second quest is a daily one. As long as someone on your team hasn't yet completed the quest for the day, there's a 50 percent chance of a Monkey Elder spawning at the start of a match. Catching it causes it to drop an envelope that grants 100 gold to anyone with the quest unfulfilled. You can do this every day, conceivably eaing almost 3,000 gold over the course of the month.

Along with the new content, there are a number of balance and gameplay changes. These include adding a timer when someone is invulnerable or in stasis; towers, forts, and keeps all do 50 percent more damage to players; Nova has been reworked to make her more viable; Rehgar's talents have been changed; and Gall has seen changes to both some talents and his skills.

You can see the full patch notes on Blizzard's website. As for the next update, we don't yet have a date, but we do know Diablo II's Necromancer is coming soon.
