You can use Visual Studio Application Lifecycle Management (ALM) to manage your product lifecycle, reduce risks, and improve efficiencies. When you install or upgrade to Visual Studio Team Foundation Server 2013, you and your team can benefit from the new features and supported tasks outlined in the following table.
Use Git for version control (requires that you create a Git team project).
Get more work done in your web browser with enhanced version control features. Enhancements have been made to the navigation; viewing code, changesets, shelvesets, annotations, and history; and administering permissions.
Create or reply to comments on changesets or commits using the web-based Version Control Explorer. This allows you to engage in conversations with your teammates on source code changes. Comments can be added to changesets and shelveset or Git commits.
Undock () the Pending Changes, Changeset Details, and Shelveset Details pages from Team Explorer and open them in new windows.
Find information about your code without leaving the editor when you use CodeLens in Visual Studio Ultimate.
