Patch 2.2.0.7835

Patch 2.2.0.7835 is a Hearthstone patch made available on 25 February 2015. The patch added a new card back, made improvements to Spectator Mode, and made various minor adjustments.

General

 * The following card back has been added to Hearthstone:
 * Lunar Card Back: Acquired by reaching Rank 20 or higher in Ranked Play mode during the month of February.
 * When a match you are spectating ends, your client will be put into a waiting state until your friend joins another match. You’ll automatically connect to their next match without having to re-enable Spectator Mode. How convenient!
 * Mimiron's Head has an AWESOME new play animation. Go ahead, push the big red button!
 * [iPad/Android] You should no longer see the “You have been disconnected” message when you start up the game.
 * [iPad/Android] The in-game friend’s list should now open much faster.

Bug Fixes

 * Players will now continue to spectate a match even after 30 minutes of inactivity.
 * Cogmaster has taken a break from constructing mechanical menaces and has given himself a tune-up! His attack will now properly increase when a Mech is in play, even after his Attack and Health stats have been swapped.
