Apache Subversion vs IBM Rational Synergy

Apache Subversion is a free, open-source centralized version control system for individual users through large enterprise operations. It versions directories, files and free-form key/value properties, with atomic commits that apply only when the complete change succeeds. Branches and tags use copy operations with a small, constant space requirement, while merge tracking assists changes between development lines. File locking is optional, and selected files can require a lock before editing. Repositories can be served through Apache HTTP Server using WebDAV/DeltaV, or through the standalone svnserve server, including SSH tunneling. Subversion supports Windows, macOS and Linux, with API and self-hosted deployment options. It offers native large-file handling, sparse checkout and nested repositories. TortoiseSVN and Eclipse or NetBeans integrations are identified as separate third-party projects rather than core features. The project publishes source code, while binary packages are maintained by volunteers or other projects. Community support comes through user and developer mailing lists. Archived releases outside currently supported versions lack community support, and experimental features in the 1.14 release notes carry no backward-compatibility promise.
