SmartSVN 5
SmartSVN is a graphical SVN client. It combines a mature user interface with the power of SVN (Subversion), providing professional version control for everyone  on Windows, Mac OS X and Linux.
SmartSVN has powerful features like the built-in File Compare/Merge, Conflict Solver and Tag and Branch handling which make your daily work with Subversion as easy as possible.
SmartSVN is the consequent successor of SmartCVS which helps thousands of users to sail around the CVS cliffs. SmartSVN is more than a simple wrapper around command line executables. Based on the open source library SVNKit, it has been designed as a graphical SVN client from scratch which works together with your Subversion server out-of-the-box.
SmartSVN is available in two versions, a free Foundation version and the powerful Professional version.
