Change your steam command line to read as the following
"C:\Program Files\Valve\Steam\Steam.exe" -beta sdk (if your installation dir is different you probably already know how to change it)

Features:
* Added support for HDR map compiles in Normal and Expert build dialogs
* Added SDK support for DoD
* VGUI Model browser with substring filtering, 3D preview, and reference grid to indicate the size of the model. Camera controls are:
* left mouse: rotate
* right mouse: zoom
* middle mouse or SHIFT: translate
* Overhauled Autovisgroups
* Added many new Auto visgroups
* Created a separate tab for Autovisgroups in the Filter dialog
* Disallowed users changing Autovisgroup membership, deleting Autovisgroups, etc.
* Objects that are loaded in a hidden state without being in a user visgroup will throw an alert message and will be placed in a User visgroup named “_orphaned hidden”
* Objects hidden by a user created visgroup can no longer be made visible by the actions of the auto visgroup.
* Filter dialog is now resizable

So you plugin devs can start w/ those DoD: Source plugins now! :p
