The Data Management – Version Control page of the Preferences dialog allows you to set up version control options. SVN - Subversion is built-in and is, therefore, installed by default. This extension delivers the implementation of version control functionality through the use of SharpSVN. This implementation has full support for Unicode (multi-byte) characters in file names. As an example, this allows you to add files to your SVN VCS repository that include Russian characters in their names.
The Data Management – Version Control page is part of the main Preferences dialog that is accessed by clicking the control in the upper-right corner of the design space then selecting the Version Control entry under the Data Management folder.
