An update for Visual Studio 2013 is available for download.
Compiler and CRT
VS 2013 Update 4 includes a new version of the C++ compiler (18.00.31101.0). There's no new C/C++ Runtime--it still uses CRT version 12.0.21005.1 from VS 2013 RTM--, but there are updated remote debugging tools packages.
Visual Studio Graphics Diagnostics: This update includes a new GPU usage tool. Note that this tool is included with VS 2013 Express for Windows, VS 2013 Community, and VS 2013 Pro+.
Community Edition: There is now a new Visual Studio Community 2013 Edition for individuals, students, and hobbyists who want to target multiple platforms, use VS extensibility, and the graphics debugger.
