Steam have released updates for both Team Fortress 2 and Day of Defeat: Source. The updates will apply automatically when you next restart your Steam client.
Chief among the updates are these fixes:
- Added flag to the gamerules entity so map authors can override the HUD type being used. Allows map authors to force CTF or CP HUD to be used if they mix CTF/CP entities in the map
- Fixed players getting stuck in the "prepare to respawn..." countdown loop
- Fixed server crash when trying to load a map that contains control points with duplicate index values
- Changed AutoTeam to give new players to the attackers on attack/defend maps if the teams are even
And so on...
