Obviously, no 'version 2' release has ever happened. The code exists, but it's been more of an incubator than anything else. Part of 'version 3' will be released this week in alpha, and expanded on afterwards. This will include some C code, the type-id facility, and a significantly revised version of the subject-observer/server-client pointer classes. SDL will be used to eventually provide a threading-compatible version of the library.
