Check for Updates Dialog Box
Beginning in the November 2012 release of SQL Server Data Tools, you see a Check for Updates menu option under the SQL menu.
The Check for Updates dialog box displays the version of SQL Server Data Tools that is installed on your computer, and the released version. An Update displays if the released version is later than the installed version. Click the Update button to see a description of the available updates, and, if you choose, install the most recent SQL Server Data Tools version on your computer.
The Check for Updates dialog box also has an Automatically check for updates to SQL Server Data Tools check box. When checked, SQL Server Data Tools displays a description of available updates when Visual Studio starts. You can choose to install those updates.
