Stefan Reich has released SuperVersion 1.1, a single user version control system suitable for small projects, as opposed to multiuser, server-based systems like CVS and Subversion. According to the web page, "Superversion 1.1 is feature-complete, very stable and suitable for everyday use. It can be (and is!) used for local versioning today; an extension for client/server operation is under development." Version 1.1 adds the ability to classify files as binary or text. Superversion is published under the GPL.
