Stefan Reich has released SuperVersion 1.2, 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 1.2 treats DOS and Unix newline characters the same, makes the database format compatible with 2.0, and fixes a deadlock condition. Superversion is published under the GPL.
Reich has also posted beta 5 of Superversion 2.0, which extends the product to handle multiuser version control.
