Dota 2 Update - December 13th, 2013

Today there is an update about bug fixes and the back of the skeleton king(It's the wraith king). So, skeleton king is back, i mean wraith king has risen! There is no big different on the hero, only different skin and animation. So the update is about 60MB.
The update conclude:

• Wraith King has risen (Skeleton King is back, that's mean you can play him again)
• Fixed Recruits sorting in the wrong direction 
• Fixed Captain crowns showing on all players when spectating CM games
• Added matchmaking preference to use themed or classic map (You can choose either winter or normal map)
• Ranked matchmaking will always use the classic map. (This is to minimize fragmentation of the matchmaking pool)
• Tuned quality thresholds in ranked matchmaking to wait longer and require a higher quality match
• Private lobbies will use classic map if tournament version is selected in lobby settings
• Fixed bug causing full parties of 5 players to wait needlessly when searching for Wraith-Night or Coop Bot matches 

For Frostivus (Wraith Night game mode) :

• Rebalanced both Shadow Fragments and Shining Fragments rewards
• Fixed towers sometimes becoming invulnerable
• Fixed CM hero selection being limited after a Frostivus game
• Fixed buy back cost not being reset on new game with increased difficulty
• After defeating Wraith King end panel now correctly shows up and shows fragment rewards and allows voting
• Added conversion of Shining Fragments to Shadow Fragments  

 And that's all the update for 13th December. Hope this is useful! GL :)
