"0.1" or "Agrajag" (named so retroactively) was the first iteration of Sputnik, written on a Sunday afternoon in early April of 2007. It worked and powered Kepler wiki for a few months, but the code was too ugly to be shown to the world. "Argajag" was originally designed to be a clone of JuneBug and the very first version really looked liked it. However, we slapped a navigation bar early on, since we felt the Kepler wiki needed it, and so the look and feel started diverging from there.
Agrajag was never "released" and was later deleted by mistake.
