updating QT - what are the risks?

Folks, I plan to do some development work with QT. I downloaded the latest free release, 3.2 and then looked at what was installed with SuSE 8.0 which turned out to be QT 2.3.2 ! As a lot of tools use QT, including KDE, I am hesitant to just install the new version. My question is, what are the risks to such a major upgrade? Has anyone done this already? Thanks for your input. Babu __________________________________ Do you Yahoo!? Yahoo! SiteBuilder - Free, easy-to-use web site design software http://sitebuilder.yahoo.com
