While the upcoming Hearthstone expansion, Whispers of the Old Gods, hasn't arrived yet, Blizzard is doing pre-launch preparations with a new patch. The patch changes many classic and basic cards, adds 3 new card backs, and fixes tons of bugs. Of course, that is not everything. One of the "crucial" changes of this patch is the emote replacement. The "Sorry" emote is gone and is replaced by a new "Wow" emote. I think this is one of "the best" changes done so far. Please, visit this official news blog to know more details about major and small changes done by the developers.
