Steam has news of an update to Half Life 2 : Deathmatch and also news on the release of the source code for SDK.

In advance of the Counter-Strike: Source update we've mentioned here recently, we'll be releasing an update for Half-Life 2: Deathmatch. This update will include two new weapons (the StunStick and the Slam) as well as a return of the trusty crowbar. We've decided to also include a new map called "Steam Lab."

Also included on the Steam website is news of VAC2. As usual the updates will download and apply themselves the next time you start steam. Steam lab huh, sounds kinda cheesy.
