An update to Team Fortress 2 has been released. The update will be applied automatically when you restart Team Fortress 2. The major changes include:

• Matchmaking
  • Competitive Mode
    • Abandon penalty times are now longer for first-time abandoners with a low number of games played
      
    • Abandoning a game now results in significant rank loss. This loss is always greater than losing a given match.
      
    • Fixed an issue where players could drop and reconnect too many times before triggering an abandon
  • Casual Mode
    • Matches can now start with fewer than 24 players when there are not enough compatible players in queue
      • The match will still add additional players (up to 24) as they become available
        
      • This should improve queue times for low-population regions and game modes
    • Added maps cp_gullywash, cp_snakewater, and koth_probed
      
    • Fixed not being able to cycle between spectator modes
• Weapon viewmodels
  • The field-of-view slider has been re-added to Adv. Options menu (range: 54 to 70 degrees)
    • This feature is now allowed in Competitive Mode
  • Improved and fixed many animations when using a higher viewmodel field-of-view
    
  • Removed custom animations from the sv_pure whitelist because it was being exploited
    
  • Adjusted The Cow Mangler and Black Box reload animations to be slightly faster (they now match the default rocket launcher)
• Your class portrait will now always be the innermost in the match status HUD (top center) and will have a slightly brighter background
  
• Added the Prinny promo items to the Mann Co. Store
  
• Added the Florida LAN 2016 community medal
  
• PASS Time update
  • Fixed achievement items (e.g. Civilian Grade JACK Hat) not cloaking with the Spy
    
  • Tweaks and fixes for all maps
    
  • Fix pack speed not being updated sometimes
    
  • Aiming players will no longer receive pack speed bonus
    
  • Some adjustments to reduce average round length
    • Overtime will end immediately if the winning team touches the ball
      
    • Overtime won't happen if it's impossible for the losing team to win
• Fixed players being able to avoid a vote-kick by reconnecting to the server at the right time
  
• Fixed the pd_watergate HUD not drawing
  
• Fixed Engineer teleporter exits sometimes detonating when used due to invisible geometry
  
• Fixed getting a black screen if the chat window was open when the match stats were being shown
  
• Fixed weapons not being hidden during some taunts for the Engineer, Medic, and Soldier
  
• Fixed Spy cloak causing the HUD 3D Character to cloak for the player the Spy is disguised as
  
• Fixed a client crash related to the animation system
  
• Fixed a bug where players in looping taunts could sometimes cause other clients to drop from the server
  
• Fixed not seeing particle effects for Unusual versions of Baseball Bill's Sports Shine, Ritzy Rick's Hair Fixative, and Texas Slim's Dome Shine
  
• Fixed hearing the "team wipe" Announcer audio at the incorrect times
