* Fixed a variety of server browser issues with mods based on this SDK * Fixed many warnings on various platforms * Added source code for fgdlib and raytrace * Updated many source files with the latest shared source from TF2. OSX: * Added support for Xcode 4.6 * Switched OSX builds to use Xcode instead of makefiles * Moved libs from src/lib/osx32 to src/lib/public/osx32 or src/lib/common/osx32 to match windows better. Linux: * Moved libs from src/lib/linux32 to src/lib/public/linux32 or src/lib/common/linux32 to match windows better.
