CollabNet Subversion has been architected from the ground up for distributed, Internet-based source code management providing very distinct WAN-performance advantages over its competitors. CollabNet Subversion offers new features for distributed software development including: versioning of directories, copies, renames, and file metadata; truly atomic commits; enhanced network capabilities; more efficient handling of binary files; and very efficient branching and tagging. CollabNet is the main corporate sponsor of the Subversion open source project and was the first company to integrate it into a complete solution for distributed software development.
