Updates
An updated version called Visual SourceSafe 2005 was released in November 2005, promising improved performance and stability, better merging for Unicode and XML files, as well as the ability to check files out over HTTP. It was included with Visual Studio 2005 Team System editions, but is not included with Visual Studio 2008 Team System.
At the same time, Microsoft also introduced a source control and project lifecycle management product called Team Foundation Server, which is part of Visual Studio Team System. This product addresses many of Visual SourceSafe's shortcomings, making it suitable for larger teams requiring high levels of stability and control over activities.
With Visual Studio 2010, Microsoft no longer distributes Visual SourceSafe. Microsoft now offers Team Foundation Server Basic for smaller development teams. There is a hotfix so existing SourceSafe customers can use SourceSafe with Studio 2010.
The final version of the product, Visual SourceSafe 2005, retired from mainstream support on 10 July 2012 with extended support ending on 11 July 2017.
