General:

*         Upgraded Steamworks SDK to v1.29
*         Fixed mod compatibility problem with Multiplayer Base that was introduced in September.
*         In Hammer, while using the Vertex Tool, pressing CTRL+B will snap selected vertices to the grid.

Virtual Reality:
*         Mods that support virtual reality now need to have a line in gameinfo.txt that says “supportsvr 1”. This indicates to gameui and engine that certain UI should be enabled.
*         VR-enabled mods will now start up in VR mode when launched from Steam’s VR mode.

Windows:
*         Upgraded to Visual Studio 2013. If you need to build projects for VS 2010, add /2010 to your VPC command line.

OSX:
*         Upgraded to XCode 5.
