The first update, Visual Studio 2012 Update 1, is now available. You can install it today from the download page (see "Visual Studio 2012 Update 1" under the "Additional software" section).
This isn’t just about bug fixes, it contains quite a few of those to measurably address issues reported through Connect, UserVoice, and Windows Error Reporting. This update also delivers a wealth of new functionality into Visual Studio 2012. The new functionality in Update 1 primarily spans four areas of investment: Windows development, SharePoint development, agile teams, and continuous quality.
