Blizzard abruptly announced today that Hearthstone has officially launched and updated to the new 188.8.131.5244 patch.
The free-to-play card game has been widely available for some time now, but now it's all there for keeps. Today's patch includes golden hero and special card backing visuals as rewards for ranked play. Other changes include balance tweaks, a reconnect feature, access to multiple regions, and a whole lotta bug fixes.
Players can also earn a Hearthstone mount for World of Warcraft by winning three games in play or arena mode.
