There is a client changelog on the wiki which goes back to Graal 1.3 (
http://wiki.graal.net/index.php/Crea...lient_Releases). For some reason Graal 3.1 is not listed there, and I don't really know what happened to things like the "New World" project either. Graal 3 (or 3.1 - I don't remember) brought clientside GScript2 and Graal3D, before the best of both Graal 2 and 3 were merged to make the major Graal 4 release.
