Today, a number of Valve's games-- Team Fortress 2, Half-Life: Episode One, Episode Two and Portal--have been updated.

Team Fortress 2, Episode 1 & 2, and Portal - Added support for the Novint Falcon

General - Added an option to the advanced multiplayer menu to select left or right handed view models - Fixed a bug where a spectator's wearable items could be seen floating around the player they were spectating - Fixed a bug where a fake Spy hand would appear on the screen of other players - Custom death animations now only play 25% of the time - Fixed teleporters not being build-able in some places where they should be (such as within the pit at the end of Badwater Basin) - Fixed rare client crash on connection and level change - Removed refract from water ripples caused by bullet impacts for performance reasons - Added log entries for player extinguished events using the medigun, jarate, flamethrower and dispenser - Started tracking localization settings to help make decisions regarding localization in the future - Fixed the blank progress bar in the upper-left of the screen when the client scheme is reloaded

Mapmaker requests - Added spawn flag to funcrespawnroomvisualizer that allows it be non-solid to players - Added SetSolid input to funcrespawnroomvisualizer to change solidity to players dynamically - Added OnWonByTeam1 and OnWonByTeam2 outputs to the TFGamerulesProxy

Sniper - Fixed a bad detection case in the "Friendship is Golden" achievement - Changed the description of the "Triple Prey" achievement so it better describes how to get it - Critical arrows now have a trail and correctly deal enhanced damage - The Huntsman now defaults to be right handed - Friendly arrows will no longer trigger the near miss sound on you - Fixed several sources of floating arrows

Spy - Fixed disguised Spies occasionally looking like they have invulnerability, instead of the correct fake Spy mask - Disguised spies will no longer lose their disguise weapon when they interact with a weapon locker - Fixed a bug where the spy's watch would randomly change models during play - Fixed uncloaked spies flickering in and out of the cloak effect when taking damage - The Cloak and Dagger now always regenerates at its intended rate. Previously it only regenerated at the correct rate when the spy was cloaked - Increased the Cloak and Dagger regeneration rate slightly - Capped the rate of energy loss from moving faster than run speed (falling / air toss) while cloaked with the Cloak and Dagger - The Dead Ringer's cloak consume rate has been slightly reduced, giving about an extra second of cloak time on a full meter - Emerging from the Dead Ringer's cloak now drains up to 40% of the cloak meter instead of 100%. This drain only happens if the meter is at least 60% full - The Dead Ringer's cloak meter can now be regenerated from ammo sources - The Ambassador now only crits when fully accurate and no longer penetrates enemies - The Spy can no longer change weapons from the knife while shocked by the Razorback - Force-A-Nature & Flamethrower air blast knockback effects no longer work on disguised spies - Fixed disguised Spies showing the wrong teleporter effects when using an enemy teleporter
