Yeah, with 10.3 (Panther) Apple released Safari 1.3, but only for that system, and then with 10.4 (Tiger), they released Safari 2.0, but again, only for the new system software. I've been wondering why that is? Are they afraid people won't pay to upgrade to the latest system or is there really something in the new browser versions that can't be backported to the older system relatively easy?
