Apache Subversion (often abbreviated SVN, after the command name svn) is a software versioning and revision control system distributed as free software under the Apache License.[1] Developers use SVN to maintain current and historical versions of files such as source code, web pages, and documentation. Its goal is to be a mostly compatible successor to the widely used Concurrent Versions System (CVS).
The free software community has used SVN widely: for example in projects such as Apache Software Foundation, Free Pascal, FreeBSD, GCC, Mono and SourceForge. Google Code also provides SVN hosting for their free software projects. CodePlex offers access to SVN as well as to other types of clients.
The corporate world has also started to adopt SVN. A 2007 report by Forrester Research recognized SVN as the sole leader in the Standalone Software Configuration Management (SCM) category and as a strong performer in the Software Configuration and Change Management (SCCM) category.[2]
SVN was created by CollabNet Inc. in 2000, and is now a top-level Apache project being built and used by a global community of contributors.
