• Fixed a bug in networking that would cause long stalls (up to 10 seconds) when a split packet would not be reassembled properly, which forced a full update to all clients
  
• General optimization to tracelines
  
• Fix for broken .dem file playback
  
• Added backward compatibility code to allow demos recorded with protocol 12 to continue to be playable under protocol version 13
  
• When showing "WARNING: Connection Problem", now indicate the number of seconds remaining before an auto-disconnect will occur
  
• Fixed a bug that would cause NULLNAME to be shown as the player's name in the scoreboard for a short time
  

Team Fortress 2

• Fixed exploit where spectators could spawn into the world without actually joining a team
  

Hydro map changes

• Fixed an exploit that would allow players to jump out of the map
  

Granary map changes

• Cover changes to the first capture points of both teams. Reduces some of the sight lines for defenders, and should make the area easier to capture
  
• Teams that are holding more points will receive a greater spawn time bonus (spawn timer reduced for the winning team). This should help attacking teams build momentum
  
• Minor visual tweaks to the BLU side between capture points 2 and 3
  
• Clipped off a super high (demo pipe jump) perch in the middle area
  
• Increased base round timer to 10 minutes
  
• Added windows overlooking the final cap from the capture point 2 building (via new room next to conveyor route)
  
• Minor changes to lighting in the middle area
  
• Moved the middle spawn points farther forward (saves 6-7 seconds off a Heavy's run from this spawn to enemy capture point 2)
  
• Reduced spawn advantage/penalty to a total of -/+ 6 seconds when on the final cap (from 10 seconds)
  
• Fixed material alignment and model interpenetration issues in home spawn rocket rooms
  

SourceTV

• Increased default bandwidth rate from 5 to 8 KB/sec for spectator clients
  
• Increased SourceTV demo buffer size for table class descriptions from 64 to 96KB. Team Fortress 2 was running over this
  
• Performance improvement for copying unreliable data buffers to SourceTV clients
  
• Updated the list of events in TF2 tagged for the director to play
