Renamed/copied/moved/removed files retain full revision history. Git SVN is a feature in Git that allows changes to move between a Subversion and a Git repository. Subversion does not have such a feature and what its documentation recommends to use instead is very different in nature. The open source community has used Subversion widely: for example, in projects such as Apache Software Foundation, Free Pascal, FreeBSD, SourceForge, and from 2006 to 2019, GCC. After the developer has made changes, they send the changed files back to the central server. In SVN, branches are created as directories inside the server. Files are stored as links to the most recent change; thus a Subversion repository is quite compact. In Subversion, the only difference between branches and tags is how they are used. Merge tracking – Merges between branches will be tracked, this allows automatic merging between branches without telling Subversion what does and does not need to be merged.
