Subversion moves back into the Adopt section of the radar because it is a solid version control tool suitable for most teams. We consider Subversion’s features to be the basic standard for a modern version control tool. ThoughtWorkers continue to embrace and recommend Distributed Version Control tools such as Git and Mercurial, but we caution that these systems often require deeper understanding to get the most out of them. New to the radar is GitHub, a “social coding” tool supporting both source code hosting and social networking. GitHub is arguably one of the main reasons Git has become the leading DVCS tool, and GitHub’s collaboration features are often used by enterprises that need to support distributed teams.
