We finished the RTM release of Visual Studio 2012 in August 2012 and launched it in September. At that time, we committed to releasing new value into Visual Studio via a regular cadence of Visual Studio Updates, and in November 2012 we released our first, Visual Studio 2012 Update 1 (VS2012.1), which contained not only bug fixes and performance improvements, but also new functionality spanning four primary areas of investment: Windows development, SharePoint development, agile teams, and continuous quality.
