- Fixed a major oversight in Source 2013 which was causing some code to think all logic entities were worldspawn - Added WIP background nodraw for point_cameras set to not draw skybox at all - Fixed map-specific talker not flushing on restore - Added optional HUD hint to code-based game instructor hints - Added workaround for suspicious crashes in HL2 NPC rappelling code (reported by 1upD) - Made antlions summoned by npc_antlionguard report as dead when removed with the "Kill" input - Fixed math_mod not saving mod value (reported by Klems) - Added SDK_WindowImposter, which uses the SteamPipe cubemap bug workaround and includes support for parallax corrected cubemaps - Updated thirdpartylegalnotices.txt to mention the Squirrel API - Fixed incorrect type checking for script instances in VScript - Added a bunch of new misc. VScript constants - Added a few new base VScript functions - Added a separate "Clientside Script Language" keyvalue to worldspawn for VScript, allowing client scripts to use a different language from server scripts - Fixed worldspawn crashing the game when running entity scripts (reported by krassell) - Fixed manifests creating a second worldspawn, allowing them to function properly in HL2 - Added tons of remapping-related fixes for instances and manifests, including node IDs and overlay remapping - Added a keyvalue to func_instance which allows vector axis lines to be remapped properly - Added support for manifest root path instances in VBSP - Added missing PrintBrushContents() contents to VBSP - Added -nohiddenmaps parameter - Made manifest cordon somewhat functional
