I used 0.5.2 because it was the version available before or early during the axe contest (or was it 0.5.3? I can't remember). EDIT: confirmed 0.5.2. (Idiot, you have a folder called Axe0.52, doh. soz talking to myself) It was also the first version i used. Anyway I only switched to 1.0.5 a few days ago.
