Safari 2.0.1 vs Safari 1.3.2
I'm a Portuguese web designer who strives to build pages as universally accessible and compatible with the greatest number of platforms and browsers (including Safari) as possible. I bought a Mac Mini where I maintain 15 different browsers and versions, just for testing purposes. I presently have the Mac OX X(10.3.9) with the Safari 1.3.2. and I would like to know which are the main differences between this Safari version and the newest 2.0.1 version (or at least where I can find this information) so I can evaluate if an upgrade of both the OS and browser justifies itself... I really wouldn't like to do the investment if differences are not so notorious, mainly respecting rendering capabilities (CSS interpretation, web standards conformation and so on).
Thank you very much for your help!
